How to install a driver for Wi-Fi MediaTek MT7921 and MediaTek MT7961 in Linux

This note will show how to solve the problem with Wi-Fi adapters MediaTek MT7921 and MediaTek MT7961, which you can find in the latest models of laptops, for example, such as the ASUS ROG G15 and ASUS TUF GAMING A15 FX506L-HN004.

We need the MT76 driver, which ensures the operation of the following chipsets (source):

  • MT7610U 802.11a/b/g/n/ac 1t1r 2.4/5GHZ USB Chip
  • MT7612/MT7662 802.11a/b/g/n/AC 2T2R 2.4/5GHZ PCIE/USB Chip
  • MT7630E 802.11a/b/g/n 1t1r 2.4/5GHZ PCIE Chip
  • MT7610E 802.11a/b/g/n/ac 1t1r 2.4/5GHZ PCIE Chip
  • MT7603E 802.11b/g/n 2T2R 2.4GHZ PCIE Chip and MT7628 802.11b/g/n 2T2R 2.4GHZ SOC Device (4.7)
  • MT7615 802.11a/b/g/n/ac 4t4r 2.4/5GHZ PCIE Chip (5.2)
  • MT7622 802.11b/g/n 4t4r 2.4GHZ SOC Device (5.7)
  • MT7663 802.11a/b/g/n/AC 2T2R 2.4/5GHZ PCIE/USB/SDIO Chip (5.eight)
  • MT7915 802.11a/b/g/n/ac/AX 4T4R 2.4/5GHZ PCIE Chip (5.9)
  • MT7921 802.11a/b/g/n/ac/AX 2T2R 2.4/5GHZ PCIE Chip (5.12)

There is no MT7961 on this list, but the nucleus module for MT7921 is responsible for its work.

You can see the numbers in brackets. they mean the version of the nucleus, starting from which the driver is supported. Yes, the good news is that the driver is supported by the Linux nucleus from the box, that is, in theory, the user does not need to take any action-the Wi-Fi adapter should “just work”.

But the problem is that the Linux core with version 5.12 relatively fresh and widespread not on all distributions. For example, already at the time of writing, a preliminary version of the nucleus 5 is available.15, and the ARCH Linux is already used by the nucleus 5.fourteen. But in Ubuntu 21.04 Nuclear 5 is used.11, respectively in Linux Mint, an even older core.

  • Wait for your distribution to receive the latest version of the nucleus (you can never wait, since only new distribution issues will receive a new core)
  • Install the latest version of the nucleus yourself (there is some risk to the system)

So you need to install the kernel 5.12 or later. how to do this depends on a specific distribution. This instructions will show how to install the latest version of the nucleus in:

I have a kernel 5.12 or later, but MediaTek MT7921 (MediaTek MT7961) do not work or work with problems

If you have already installed fresh core 5.12 or more new, but Wi-Fi adapters or Bluetooth work with problems, then this section is for you.

MediaTek MT7921 and MediaTek MT7961 requires firmware, which, although there are standard distribution repositories, are usually not installed by default.

In Ubuntu, Linux Mint and their derivatives, follow the following command:

In Debian derivatives, run:

In Kali Linux, follow the following command:

In Arch Linux, Manjaro, Blackarch and their derivatives, complete the command:

Questions and answers to Wi-Fi in Linux

Why does the MAC address change, even if the program is not used for this

Many modern distributions are constantly tuning to change the MAC address. Details about this, as well as how to disable or vice versa, turn on this function in the article “How to change the MAC address in Linux, how to enable and disable the automatic change (spun) Mac in Linux”.

How to find out if Wi-Fi will be supported for an audit of Wi-Fi networks

If you want to determine, the monitor and wireless injections support another adapter that is not included in the list, then study “How to determine which Wi-Fi adapter is suitable for Kali Linux”.

Modern Wi-Fi cards for wireless audit

Two.band wireless adapters with support for the monitor mode and wireless injections, as well as with support for the AC standard:

  • Alfa Awus1900 (Chipset: Realtek RTL8814AU)
  • Trendnet Tew-809ub (Chipset: Realtek RTL8814AU)
  • ASUS USB-AC68 (Chipset: Realtek RTL8814AU)
  • Alfa Awus036ach (Chipset: Realtek RTL8812AU)
  • Alfa Awus036ac (Chipset: Realtek RTL8812AU)
  • ASUS USB-AC56 (Chipset: Realtek RTL8812AU)

Any of these adapters will be relevant for many more years.

How to see what is happening with wireless intenses

The following commands will help you see absolutely everything that happens behind the scene during, for example, unsuccessful connections.

You can use the conclusion of the following commands to solve any problems with Wi-Fi.

The next team in real time will show everything that happens in your system. for example, when connecting a wireless adapter, it will show which driver is downloaded or what problems arose. Messages will also be displayed by applications:

The output of the program is very extensive, but its study can suggest the reasons for the problem. See also “How to use Journalctl to view Linux system logs”.

The next team will tell you about everything that happens at the level of the inter.sequences. how the IP addresses are assigned to intenses and what routes are prescribed in the system:

And this team will show all the events associated with wireless network intenses:

These three teams are the most important source of information to resolve non.obvious problems. Study their conclusion or provide the withdrawal of these commands if you are trying to jointly solve your problem with Wi-Fi.

How to find out how much traffic was transmitted

Why in Wi-Fi at 5 GHz are not available to the channels between 64 and 100

You can see what frequencies your Wi-Fi card supports.

The set of channels varies slightly, but in any case, the frequency in the range of the 64-100 channels is completely unavailable. That is, they are not even disconnected, but no matter how simply they exist.

You may also be curious why there is a gap between the 64 and 100 channel in Wi-Fi 5 GHz?

The range of 5.35–5.46 GHz lists various applications, including “air radio navigation”. There will be channels from 68 to 96. Obviously, they do not want equipment with Wi-Fi support even by chance, which could interfere with the aircraft navigation.

These channels are used together with meteorological radar. The router using these channels should check the presence of a meteorological radar. If a meteorological radar is detected, the router must switch to another channel on which there is no meteorological radar. I do not remember how quickly the router should stop using the channel. It could be 10 minutes.

If the router switches Wi-Fi channels, customers usually do not switch. Everything that was connected loses its connection. I think that the controller can switch customers to a new channel before the old one is disconnected, but again I’m not sure.

It can be corporate equipment. Consumers cannot afford it.

The lack of mentioning the channel in the list of supported frequencies, as well as the next entry means that your Wi-Fi device is not able to work on this channel:

You can also see the notes with “No IR”:

No-IR flag (no-initiating-radiation) is translated as “lack of initiating radiation”, that is, the channel in principle can be used, but cannot be the first to send any data, that is, it will be used only if it receives from the Beacon router (lighthouses) these frequencies.

You can also see the notes with “No IR, Radar Detection”:

We have already figured out No IR, and “Radar Detection” apparently means that if a radar is found at adjacent frequencies, this frequency also ceases to be used. but this is rather a hunch, if you know a more correct answer, write it in the Комментарии и мнения владельцев.

Is it possible to use old adapters supporting only b and g Standards to hack

Yes, such adapters are able to carry out almost all attacks even on TD working at the standard N. See details in the article “For what attacks are old Wi-Fi adapters”.

Drivers and firmware

Wi-Fi drivers in Linux. Support for Wi-Fi Adaptors in Linux

Linux currently supports most Wi-Fi cards and drivers for them are already preinstalled in the system (they are part of the nucleus). That is, when buying a new Wi-Fi adapter or installing Linux on a laptop in the vast majority of cases, no action is required-Wi-Fi adapter will just work.

In rare cases, you will need to install the driver and/or firmware from standard repositories.

In exceptional cases, it is necessary to compile the driver from the source code.

You will find a list of installed drivers in the folder

If for some reason the driver has not yet entered the core, then he may be present in standard repositories in the form of separate packages:

  • Realtek-RTL8188EUS-DKMS (driver for RTL8188EUS, in some distributions is present in repositories; in Arch Linux is present in AUR, like other drivers mentioned here)
  • Realtek-RTL88XXAU-DKMS (driver for RTL8812AU/21AU). How to install this driver in various distributions, as well as many useful tips, see the article “How to install a W-Fi driver for cards with chipsets RTL8812AU/RTL8821AU (Alfa Awus036ach, Alfa Awus036ac)”
  • RTL8814AU (this driver for RTL8814AU chipsets, See details and hints in the article “How to install a W-Fi driver for maps with chipset RTL8814AU (Alfa Awus1900)”
  • RTL8821CE (this is a driver for Wi-Fi adapters based on the Realtek RTL8821CE chipset, there is no default, but in some distributions it has already been added to the repository). See Details on the installation in the article “How to install the Realtek RTL8821CE driver”
  • ATH10K_PCI driver, Qualcomm atheros qca9377 802 chipset.11AC Wireless Network Adapter: Wi-Fi Adapter Qualcomm atheros QCA9377 does not capture data packets in monitor mode (decided)

So, the drivers for most Wi-Fi adapters are built into the core and, therefore, are already installed on any Linux. Start by connecting your wireless card and try to connect to the access point.

If problems arise, look in the repositories of the driver and/or firmware for your device.

5 Things To Do After Installing Manjaro

Linux drivers firmware

If you are familiar with the article “Linux nuclei modules”, then you know that many devices for proper work need two things: the driver and firmware. The driver requests a firmware from the file system in /Lib /Firmware. This is a special file required for hardware, this is not a binary file. Then the diver does everything you need to load the firmware into the device. Firmware programming equipment inside the device.

In addition to complete inoperability, when the system does not see a Wi-Fi device and wireless networks, the absence of firmware can lead to partial inoperability when the system sees the device, but cannot use it.

Examples of problems that can cause missing firmware:

Installation of the main firmware packages required for Wi-Fi devices is performed by the following commands.

A difficult way

Compared to the above, this method is a little more complicated. In the above team, the network profile was automatically configured. Now we will set the profile manually. But don’t worry, it will not be much more difficult. let’s start!

The first thing you have to do is to find out the name of your Inte Wee, as a rule, it is WLAN0/WLP2S0, but there may be many exceptions. To find out the name of your Inte Wee, you must use the IWConfig command.

In this submarine you will see various examples of profiles.

Copy the example of your profile in/etc/netctl/your_profile

You can view the contents of the profile using the command:

Edit the following fields in the profile using VI or Nano:

Interface: It should be Wlan0 2. Essid: your network name 3. Key: Your network password

Netctl launch

You should see a profile created using Wi-Fi-Menu, for example Wlan0-SSID; Or, if you used a complex way, then you should see the profile created by you.

Launch your profile using the command:

At the end, you must complete the following command:

At the same time, Systemd will be created and activated, which will be launched when downloading a computer. Now you have set up Wi-Fi in your Arch Linux.

Network Manjaro Linux

After installing a new operating system, it needs to be configured to work. Change and configure the main parameters. The first where to start starting this connection to the Internet. So this is linux Internet is very important. After installing Manjaro, if you have a DHCP server. OS get all the settings automatically and gain Internet access. But you need to know and be able to configure all the parameters on your own manually. over, in Manjaro this is done very simply, let’s see how. This article will be useful to beginner users Manjaro.

And so in order to change the network settings, you need to find the network icon in the lower right corner, click PKM and select “Change the connection”.

All active connections will be displayed in the window that opens. Select “Wending connection 1” and click on the settings icon from below.

In the connection settings on the first “Basic” tab, you can change the connection name, configure the auto carrier, select users that will have access to this connection. And also configure the VPN connection.

We go to the Ethernet tab. You can select the device, configure the parameters “MTU”, configure awakening on the local network. Set a password for awakening. Select the speed of the local network 10/100Mbit/s and 1/10GBIT/s.

On the IPV4 parameters tab, set up a method for obtaining network settings. If these static parameters indicate the address, mask, gateway and DNS. Here, in general, everything is as in Windows.

We save and check the operability of the network. Everything is quite simple and clear.

Of all Linux systems with which I worked, I can say that Manjaro is the most convenient and understandable. Very similar to Windows. If you have a choice for which Linux OS, then I advise you to try manjaro.

Wi-Fi does not work after awakening from the sleeping mode on Linux

The article was written with the calculation of indexation of one insidious, unpleasant low.frequency error, which he himself could not decide for a long time, and finally decided even without the advice of good people https: // t.Me/Johenews/723?Comment = 34811. I hope someone will be useful to someone except me.

Description of the problem

Exactly a year I was periodically worried about the next problem. On my laptop Lenovo Lenovo Legion 5 15arh05, when leaving the sleeping mode, t.e. When opening the lid of the laptop, the system did not always connect to the Wi-Fi network. over, Wi-Fi adapter stopped working. Not a single network within the radius was visible. And at the same time, in the context menu when clicking on the network icon, two errors were displayed:

which cyclically replaced each other endlessly.

That I just did not try to do, no manipulations led to success. If you ask: “I restarted the Networkmanager service, then I will answer:“ Yes, I restarted, with the command ”Sudo Systemctl Restart Networkmanager. And this did not lead to the result. The reloading of the system helped to make the network, or re.opening/closing the laptop cover, in the hope that this lottery ticket will give a win this time this time.

It feels like about once out of five exits from the sleeping regime ended in failure, but the patterns in this were not. At the moment when you do not have the Internet, google what. it becomes problematic, t.to. This must be done from a neighboring device. Usually you open a laptop on the case, and it is often not time to solve the problem without the Internet without the Internet.
