Distance: A very interesting parameter, if clients are in the same room and approximately at the same distance, well, let’s say everything is within a radius of 20 meters from the access point, then indicate indoors, if you have a field or conference room in an open area, and clients are at different distances of more than 0.20 meters then specify dynamic. And thirdly, if the clients are at the same distance, say 1 km, then indicate that. This option allows Mikrotik to use a built-in algorithm to calculate whether the package has been delivered to the desired addressee.
Periodic Calibration: The fact is that the WI-FI chip heats up during its operation, and because of this, the frequency may move down a little, respectively, enable this option. Leave the next field equal to one minute. Frequency will be calibrated every minute.
I didn’t want to write about this item. Hw. Protection Mode: This item can help solve the hidden node problem by specifying “rts cts”. Quite briefly: 802.11 (aka wifi) is a unified data transmission medium (Remember the HUB device), and the 802.11 standard states that clients themselves determine between themselves who and when will record, BUT there is one nuance, this condition will work, only if customers see each other directly. If two clients start writing at the same time, then we get a collision. As an example, let’s imagine a certain field (The one that is on the Windows XP desktop). On it is the access point in the figure, a red dot, and its radius is pale red. And also Shraibikus (A), Vasya (B), Kolya (C) Shraibikus and Vasya can be normal participants and work in the network without interruptions, but, because of Kolyan, everyone may have problems, the fact is that Shraibikus and Vasya can communicate directly and determine which of them will broadcast in a given period of time. But Kolya does not see any of the participants in our network, and can safely broadcast at any time, even when Vasya or Shraibikus will also broadcast, because of this, collisions appear.
Let’s go back to setting up MikroTik with the rts cts value, if it’s just that “The access point itself will control who to broadcast at the moment”, which will solve the problem of the hidden node. This parameter will slightly reduce the bandwidth and increase the load on the access point. (Required parameter)
Adaptive Noise Immunity: This option allows the 802.11 chip to filter out noise, such as the reflected signal of the access point itself from a neighboring building. Set the value to “ap and client mode”
Mode:. the mode of operation of our card, select “ap bridge”
Band:. What standards will be supported by our access point, select “2ghz-b / g / n”
SSID:. Everything is simple, the name of our network
Wireless Protocol: what protocols our point will use for work, here it is worth specifying only 802.11, since we will not make a “Christmas tree from our access point”, but just a regular access point.
Country: Choose our country. Surely the question arises, why? Answer: Legislation of different countries, different frequencies are allowed, so that we do not get a layup from ROSKOMNADZOR, MikroTik will not give us the opportunity to work with other frequencies.
Antenna Gain: If you have an external antenna, be sure to indicate its gain, with a calculation of 0.5, on the connecting node. And also if you are using a cable, look at the marking on the cable, attenuation per unit of measurement (meter, 10 meters, etc.) of the cable and enter the value taking into account the cable attenuation.
WMM Support: If you are going to use Multicast, then set this option to Enabled, this will give great guarantees for the delivery of this package. If you are setting up MikroTik at home, then enable this option, but if it is a restaurant or conference room, then one client can gobble up the entire channel.
Here put only two daws HT Tx Chains. Set daws in chain0 and chain1
HT Rx Chains. Set daws in chain0 and chain1
SOHO MikroTik usually has two built-in antennas, respectively, this parameter says through which antennas to receive and transmit.
MikroTik. quick access point configuration
Very often, today’s “System Administrators” have a problem with setting up 802.11 equipment, I will try to explain it at an intelligible level.
In this post I will try to tell you how to set up a regular access point on MikroTIk equipment 751,951,2011 etc 802.11 b / g / n I will give an example of a ready-made setup and tell only about the basic settings, since it is difficult to describe the whole principle of operation and settings of 802.11 in one article Please do not consider this post as a dogma.
And so, before configuring MikroTik, I recommend resetting the WLAN settings.
(Data Rates) tab
Everything here is simple Rate Selection: select Legacy extended support (for old devices), without this option, the old barcoder did not want to get along with Mikrotik
(TX Power) tab
1W (by default, be sure to remove). Microwave))))
I strongly recommend setting the value equal to 15 and if not enough, then raise no more than 17-19.
Actually that’s all, we are almost finished now we need to select the channel (frequency) and channel width. It is at this stage that I most often make mistakes, so I left it at the end. And so we will immediately discard the channel widths of 5 and 10 MHz, since half of the home equipment will not work at such a width. In the next posts I will tell you where you can use such a width.
The following range is available to us 2412-2472, by tricky mathematical analysis, we found out that a width of 60MHz is available to us. Let’s see a spectral analysis of the entire range. [admin @ test] / interface wireless spectral-history wlan1 range = 2412-2472 We see that for us the best option is frequencies 2425-2445 (2437)
The channel width is chosen simply if we have only a couple of points in the entire range, and all of them are without any jambs, something like a multicast, etc. Channels 2412-2457 can be used as Above Channels 2432-2472 can be used as Below But use this width only when you really have a clean frequency.
It is also worth recalling once again that WI-FI is a unified data transmission medium. If suddenly, at the same frequencies (2452-2472), a client with 802.11 g appears, then all participants of this frequency will work at the same speed as our client with an old card.
A handy TV widget with an extensive library of movies and TV series. Digital television is also available, for which no payment is required. You can find popular terrestrial channels, as well as some thematic channels that are usually available with a cable connection.
For users with a weak Internet, it is possible to set the quality of the TV signal transmission.
Setting up free channels on Smart TV via IPTV
When using the software from the provider, the user will not need to worry about the stability of the connection, since the service provider has done everything possible to provide full access to Internet TV.
First of all, the TV must be connected to the Internet. The connection can be either wired or wireless. After connecting to the Internet, you need to configure it first. Information about the IP address and personal information about the user may be required. Once the connection is successfully established, the device will prompt you to sign in to your account. You can create a new account or use an existing one.
But it is absolutely not necessary to activate a special tariff from the provider in advance in order to watch TV channels. You can save some money by using third-party software. For its installation and subsequent use, you will definitely need an Internet connection. It doesn’t matter which type of connection you use (wired or wireless). The most important thing is that the speed is sufficient for playing streaming video from the Internet. Wired interfaces usually guarantee higher signal speed and stability, but they are not very convenient for placing a TV in a room.
After the installation is complete, the user will be able to launch the program and start using various playlists. All names and addresses of playlists are entered manually. It is not as convenient as using TV from the provider, but does not require additional payment.
What you need to watch
You can watch TV on Smart TV Samsung through special programs or through IPTV. The basic IPTV package for Smart TV is often provided by an Internet provider (Rostelecom, Beeline, Megafon, etc.). In this case, the amount of payment for using the connection may increase compared to the standard mode. Therefore, it is difficult to call this approach free, despite the fact that it is extremely convenient.
The program consists of external and internal directories. There can be an unlimited number of external ones, while there is only one internal.
To add a new directory, you need to do the following:
- go to the “Content” section;
- go to the “External” tab;
- click the “Add” button;
- enter the directory address and its name.
To add an internal list, click the Get button in the General section. The list will be able to function for a specific code only for a day. After that, you will need to copy the new code from the SS IPTV website.
How to set up free channels on Samsung Smart TV?
Smart TV functionality on Samsung TVs allows you to use the capabilities associated with the transfer of media files over the Internet. Smart TV can provide the user with a certain set of channels that will not need to be paid for separately. Free channels on Samsung Smart TVs are not that difficult to set up, but adjusting the broadcast settings can be difficult. So it is better to get acquainted with the specifics of the connection in advance and learn how to properly configure the channels.
A convenient service that allows you to quickly find films of interest and watch them online. There is no limitation in signal sources. You can use online movie libraries, removable media and playlists with channels with equal convenience.
In addition to viewing the contents of the playlist, the user can also create his own list of TV channels. It was these qualities that allowed the program to gain recognition from Samsung Smart TV owners.
To expand the capabilities of the application, you can use an additional program called RemoteFork. nStreamLmod. This software will allow you to comfortably watch videos from hosting, access online cinemas and run files from torrents without downloading them first. It should be noted that for the full functioning of this set of programs, it is advisable to combine a TV with a computer.

The program is paid, but has a trial period of 30 days.
Another quite successful application, which is loved by the user for its extremely convenient category “Cinema”. There are a large number of sites where you can watch movies and TV shows for free.
For fans of traditional TV, there are channel packages, among which there are both paid and free. You can add your own playlist.
Unofficial applications for watching TV over the Internet
There are many programs that allow you to watch TV channels absolutely free of charge over the Internet. Consider the most popular software.
Free channels on Smart TV
All free channels on Samsung TVs are available by entering the desired address in the TV menu. Addresses include a playlist (set of channels) that can be viewed for free when connected to the Internet. Actual addresses of playlists are placed by IPTV providers on their sites.
How to set up Internet on Samsung Galaxy A3?
The full potential of a smartphone can only be unleashed when it has the Internet. This is especially true of a flagship like Samsung like the Galaxy S3.
The device model is equipped with the latest Android operating system version 4.0.4. And it would be a real crime to use the flagship exclusively for talking on the phone.
Only with the Internet all its possibilities will open up for you, social networks and popular resources will become available.
But for this you need to know how to set up the Internet on the Samsung Galaxy A3. And today you will learn how you can do it. over, such settings will not take much of your time.
After reading the article, you will learn how to independently configure the Internet on your smartphone, while saving your money. After all, such a service in mobile salons is not cheap.
- Order automatic Internet settings from a mobile operator.
- Configure yourself manually.
- Via Wi-Fi.
Of course, it’s easier than ever to contact a mobile operator. To do this, you just need to make a call to the operator and tell him the model of your gadget. After that, you will be sent automatic settings that you need to save.
In some cases, there are no automatic Internet settings for a specific model.
It also happens when you get not settings for regular Internet access, but VAP access (do not be surprised later where money instantly disappears from your account).
The most reliable one is to set up Internet on Samsung Galaxy A3 manually. This is done by entering an access point. And it’s easy enough to do it.
Access points can be taken on the website of your mobile operator or by calling.
Then go to the “menu”, “settings”, “mobile networks” (the last item can also be found in other tabs).
Find the “access point menu d / d” and on the screen select “create a new access point”. The name does not matter, it can be anything. Proxy. leave the field blank or just turn it off.
Do not enter anything, at the bottom of the screen type with the touch keys “save”.
The access point you created will appear in your APN list. It remains to make it active, restart the smartphone. Done. you have internet access.
In this case, you will need to make settings in areas where Wi-Fi is available. Look for “applications” on the gadget (located in the lower right corner), then “settings”.
Now we need the item “wireless” (make sure Wi-Fi is on). Choose a network. If it is not added, then you need to add a network (menu. add a Wi-Fi network).
The network will ask you for a confirmation key, enter it.
Everything, you can use the Internet and the advantages of the flagship.
3G internet connection
Another method that comes in handy if you are out of range of Wi-Fi, for example, on the road.
Such a connection is suitable for those who do not have restrictions on using the Internet.
If there are restrictions on Internet traffic or you pay for the volume of its use, then avoid watching videos or other voluminous resources.
We do the settings like this. We press “applications”, “settings”, “additional settings”, “mobile networks”. In the latter, we mark the item “mobile data”.
We configure the access point. To do this, we remain in the same “menu” just find “access points”. We register (usually it is already registered). If not, see the second method of Internet settings.
That’s all. Now you know how you can set up the Internet on the Galaxy A3. I would advise not to stop at one connection.
It is rational to use two, it will give many advantages.
So, a 3G connection will allow you to connect to the Internet from anywhere, but this involves considerable expenses, and Wi-Fi gives you the opportunity to use free traffic.
How to share Internet from Samsung Galaxy over Wi-Fi
The easiest way is to distribute the Internet from a phone via Wi-Fi to a computer, laptop, tablet or other smartphone. At the same time, keep in mind that only mobile Internet (received from a telecom operator) can be distributed via Wi-Fi, the process itself is as follows:
- On your Samsung smartphone, go to Settings. Connections. Mobile Hotspot & Tethering.
- At the top, turn on the item “Mobile hotspot“. If you are told that you need to turn off Wi-Fi for this, agree (since we cannot share the existing Wi-Fi connection in this way, which I mentioned above).
- In order to change the network name, find out or change the password, click on the item “Mobile hotspot” and specify the necessary data instead of the standard.
- After that, you can connect to the created wireless network from any other devices and use your phone’s mobile Internet from them.
A few nuances that may be important in the context of distributing the Internet over Wi-Fi from a phone:
- Do not forget that for the Internet to work, the mobile Internet must be connected and active.
- Some telecom operators on some tariffs block the ability to distribute mobile Internet from the phone to other devices.
- If you need to quickly connect another phone to the Internet, in the settings of the mobile hotspot on Samsung, you can click on the QR code icon in the upper right and scan the generated code with another smartphone.
- If your tariff has limited traffic, keep in mind that by connecting your PC or laptop to the created access point, you can quickly use it up (for example, if OS updates start downloading).

How to set up your Samsung TV 2018 Samsung TV set up guide: what to enable, disable and set up
How to set up your Samsung TV 2018
Setting up a new TV may seem like a daunting task, but Samsung Smart TVs are built to be user-friendly, including an out-of-the-box setup process. Once you turn on your TV, it will walk you through the initial setup, so follow the on-screen instructions to connect the remote to your TV, select your language, and connect any external devices.
If you want to start with an existing TV, you can factory reset your Samsung Smart TV in System Preferences.
The modem function works on almost any smartphones, this applies even to fairly old models. So, even on Samsung Galaxy A1000, Wi-Fi distribution is carried out without the slightest problems and interruptions.
To securely enable hotspots on your Samsung Galaxy, you first need to set a password and change other settings. If this is not done, then anyone can connect, which means that this user will be able to waste your precious traffic or, even worse, try to enter the device and steal any data.
Using third-party programs
We’ve covered a basic way of distributing Wi-Fi on a phone, however, using third-party applications, everything can turn out faster. Some programs even increase the reliability of the connection. This will be useful for the distributor from the Samsung Galaxy phone, since no one can hack it, even if they try.
Osmino is one of the most popular hotspot applications. This application allows just a couple of clicks to create a secure point from which you can distribute Wi-Fi.
You no longer need to think about how to share Internet from Samsung Galaxy. All that is required is to download a small application, install it and run it. After that, the access point settings will open. There you can enter your nickname and the desired password, after that you need to click the “Distribute” button. These actions will launch the Internet Sharing from your smartphone.
The app is quite lightweight and will run on any company device, including the Samsung Galaxy A5000.
How to turn on the access point and distribute the Internet
There are situations when the Internet is urgently needed, and it is, for example, only on a friend’s smartphone, since any modern mobile device from Samsung Galaxy has a modem function. This is a rather useful “feature” that helps to distribute the Internet to nearby devices, such as other smartphones or even a laptop. over, even a dozen devices can be connected at the same time, the main thing is that the Internet speed is enough for everyone. This function is quite simple to use. You can learn more about how to share Wi-Fi on Samsung Galaxy in the instructions below.
How to set up a wireless router as an access point
I’ve often found it helpful to get only wireless functionality from a Wi-Fi router and reuse it as an access point. Wireless routers seem to be more common and often even cheaper than wireless access points. Adding an AP to an existing wired network, or one where the primary NAT router is provided by your ISP, is usually the easiest solution; however, adding a second NAT router to your network. not a good idea especially without some tweaks to set it up correctly.
Instead of using the wireless router for its intended purpose (NAT routing, DHCP client / server, PPPoE client, etc.), converting it to a wireless access point saves you a lot of hassle and simplifies setup.
Basically, the new wireless router / access point needs to be configured to use a LAN IP in your network range (on the same subnet as your other devices) and you need to connect one of its LAN ports to your existing gateway. / router. Do not use the Internet / WAN port on the wireless router as an access point.
detailed step-by-step instructions on exactly how to convert and use your wireless router as an access point are below:
Find the IP addresses of your existing gateway / router and clients
You need to find the internal IP address of your existing modem / gateway / router that connects your local network to the Internet. On Windows, the easiest way to do this. go to command prompt (Start Run type: cmd) and type: ipconfig
In this example, the gateway / router provided by my ISP (“Default Gateway”) is set to 192.168.1.1. My client computer is located at 192.168.1.10
The line “IP Address” in the above figure shows the IP address of your computer and the “Default Gateway”. this is your main existing router providing internet connectivity. It is usually in the range 192.168.x.x.
Alternatively, you can try connecting to your router’s default IP address by looking at our router database.
Connect to your router’s admin interface to find the DHCP range.
By default, LAN clients are usually configured to automatically obtain their IP addresses, which means the router acts as a DHCP server and dynamically serves IP addresses to client computers. You need to find the range of IP addresses used for DHCP so that you can later configure your access point to use an IP address outside this range (but on the same subnet).
Samsung Galaxy S8: How to Setup Mobile Hotspot and Tethering
Log into your gateway’s admin interface, usually by entering its IP address in a web browser, and find the DHCP range:
|In this example, the DHCP range is 192. 168.1.10 to 192.168.1.100|
Note: if you do not know the password for your router’s admin interface, you can find the default values in its manual or in our hardware database.
Connect your computer to your wireless router / AP
You need to connect your computer (via the LAN port) to a new wireless router that will be used as an access point. From now on, I will refer to it as the “access point.” To do this:
Log into the admin page of the access point (you can find its IP address as you did in step 1 for your main router). This is usually done by simply entering the IP address of the router in the address bar of the browser.
Configure your wireless router / access point
After logging into the administrator interface of your wireless router, there are two things you need to do. First, you need to change its internal IP / LAN IP to an unused address in the same range / subnet as all your other devices on your LAN. Second, you need to disable the DHCP server on your new AP so that there is only one DHCP server on the network. In my case, my main LAN gateway / router is set to 192.168.1.1 and it serves dynamic IPs via DHCP in the 192.168.1.10 range. 192.168.1.100. I need to use any other address in the 192.168.1.x range for the access point:
|In this picture, my new wireless router / access point is configured to use 192.168.1.2 as my IP address and I disabled DHCP so it won’t interfere with the DHCP server from my gateway. It is important that only one device acts as a DHCP server and that the IP address of the access point is in the same range as the main router.|
Connect the access point to the local network
It’s time to connect the reconfigured wireless access point to the network. Use the LAN port on the new wireless router and connect it with a Cat5 network cable to one of the LAN ports of the existing gateway. Do not use the “Internet / WAN” port on the wireless access point!
Connect your client computer to a different LAN port of the gateway / router (if you do not restart the computer, you will need to use the “ipconfig / refresh” command in the command line to get the IP address from your router).
Note. Some older devices that do not support auto-switching (MDI / MDI-X) may require a crossover network cable (where the send and receive pairs are switched) between the two routers. This is not the case with modern hardware.
Admin test page is available and protects the AP
Now that the new wireless access point is connected to our network, with the correct IP address in the same range (and out of DHCP range). we can check if it is available and secure the wireless connection.
In the above example, I configured the wireless access point to use 192.168.1.2. Its administrative interface should be accessible by entering this IP address in the browser.
Once connected, it’s time to set up wireless security:
|Use WPA2 if both your access point and clients support it. Install a strong key and remember it. clients will need it to connect to a wireless network. Try not to use WEP encryption. it’s easy to hack as shown here.|
Test wireless AP connection
Launch the wireless client and make sure it connects to the network correctly. It should automatically obtain an IP address from your existing router / gateway (DHCP server).
Done, you now have a wireless hotspot.
Notes: If both your default gateway and access point have wireless capability, you can use the same SSID, the same security, and different non-overlapping wireless channels to extend the range of your wireless network and allow clients to connect to any one automatically. If you cannot determine the default IP address by connecting to your router with Cat5 cable, you can also find it in our broadband equipment database containing IP address and login information for more than 2600 routers.
How to set up a Samsung Galaxy smartphone to Wi-Fi router mode
In order to distribute Wi-Fi from a Samsung Galaxy smartphone or tablet, you need to follow a series of simple steps. The first thing that needs to be done is to connect to the mobile Internet, it is from it that the network that we are going to distribute comes from. For a stable speed, it is recommended to connect to 3G or 4G, as simple mobile Internet is quite slow.
This is done differently in different firmwares and smartphone models, but in each case, you first need to go to Settings and then click on the menu item. Further, depending on the firmware version, there may be different items: in one of the OS versions the item is called “Modem Mode”, in others it is “WLAN Access Point” or “Personal Access Point”. One way or another, the same function is hidden under this item, it is this function that allows you to make the distribution of the Internet work.
How to set up an access point, more will be said later.
Without USB cable
So, we need everything the same, except for the USB cable. Sequence of steps:
- We carry out points 1-4.
- In the next window “Choosing a configuration method” we select “Using a direct wireless connection” and click the “Next” button.
- It is likely that you will see a window where you need to press the WPS button on the front panel of the all-in-one printer and hold it for 2 seconds.
- After completing all the manipulations, click “Next” and follow all further instructions.
So, the block of instructions for setting up on Windows OS is completed, now let’s move on to Mac OS.
Network cable application
As with the previous instructions, check for the presence of a network cable, access point, PC, all-in-one printer and software disc. We also need to find out the SSID, password and print information about the network data of the Samsung Xpress M2070W. How this can be done will be described in more detail later.
If you have everything you need, we begin the setup itself:
- We connect the network cable to the printing device.
- Enter the printer’s IP address in the address bar of the browser on the PC (on the control panel, select “Network”. “Network Configuration”, wait for the Report to print) and go to this IP.
- After loading the site, click “Login”.
- Our equipment is new and factory-configured. Therefore, we enter the ID “administrator” and the password “sec00000” and again click “Login”.
- After the SyncThru Web Service window appears, open the “Network Settings” tab, click on the “Wireless” item, and then on the “Using the Wizard” sub-item.
- In the list that appears, select the SSID, and in the “Operating mode” tab. “Infrastructure”.
- Click “Next” and “Apply”.
- Disconnect the network cable. If everything was specified correctly, the printer should start working through the access point.
- Despite the fact that the setup is almost complete, we need to start and install the software again. We continue to follow all the recommendations that appear on the monitor, but in the “Connect a printer” window, select “Network connection”.
All possible options for setting up the printing device via the PC interface have been considered, now you can go to the configuration using the device’s control panel.
First of all, to work with a Wi-Fi connection, one type of connection can be used out of two possible:
- Infrastructure mode. communication with the printer does not occur directly from the PC to the all-in-one printer, but via a Wi-Fi point;
- “Ad-Hoc” mode. connection with all-in-one printer is made directly.
During the initial setup, you will have to create an SSID, select a security level and a password. The type of protection will depend only on the model of the router (subject to the choice of the infrastructure mode).
For Mac OS users
Let’s start by connecting the Samsung Xpress M2070W using a USB cable. First of all, we check for the following things:
- Router, PC, all-in-one printer;
- CD with software;
- USB cable.
How to set up an all-in-one printer Samsung Xpress M2070W on MAC OS:
- Connect the all-in-one printer to a PC using a USB cable.
- We insert a disc into the drive or run the software downloaded in advance from the official website.
- Double-click on the disk shortcut, which will appear immediately on the desktop (or in the Finder window, if the version is Mac OS X 10.8). In the case of using the downloaded software, run the executable file with the extension.exe.
- Run “Installer OS X” from the “MAC_Installer” folder and click “Continue”.
- We press the tick in the window with the license agreement and press the “Install” button. It will be the printing device drivers and special software that you can choose to install.
- Enter the password and click “OK”.
- Next, we need to select the type of connection. we select “Configuration of Wireless network” or “Configure wireless connection”, since we are setting up the wireless connection. After that, click “Continue”.
- It is quite possible to open a window called “Wireless Settings”. Here we select “Using a USB cable” and click “Next”. After that we indicate all the data of our access point (for a better understanding, we recommend that you see paragraph 5 “For Windows”). After specifying all the necessary data, click “Next”.
- Everything is extremely simple here: we specify the network name and set a new password (length. 8-64 digits), click “Next”.
- When a window opens, notifying of the end of the network configuration settings, click on the “Next” button and disconnect the USB cable from the PC, click “Next” again.
We have described how to connect the printer to MAC OS X using a cable. Now let’s move on to the wireless method.
Setting up with an access point
There are two options for adjusting: using remote configuration from a PC and through the all-in-one printer control panel. In turn, the setting from the PC can be divided into three ways, and from the control panel. into two.
A schematic of the Samsung Xpress M2070W printer setup guides can be displayed as follows:
- Via PC:
- Using a USB cable;
- Without him;
- Using a network cable.
- Via the control panel:
- WPS button;
- Menu button.
How to connect and configure a Samsung Xpress M2070W printer via Wi-Fi?
Good day, dear readers of our site! Today we would like to share with you an article on how to set up Wi-Fi on the Samsung Xpress M2070W printer, and provide you with step-by-step instructions. The article will be divided into two parts: the first is for an overview, and the second contains a setup guide.
