Can I install my TP-Link Adapter on wlo2 interface?

I want this to be on wlo2
Hi @LowNightSnack
Can I use 2 wifi adaptors on the my laptop on linux?
Yes. The one thing to be aware of is if you try to use 2 adapters based on the same Realtek chipset. That won't work as Realtek's drivers are broken in this regard. You can have several wifi adapters working on a computer and it can be a mix of Mediatek and Realtek based adapters or all Mediatek and it will work as long as no two Realtek adapters have the same chipset.
$ dkms status 8812au, 5.6.4.2_35491.20191025, 5.15.0-41-generic, x86_64: installed
You need to uninstall the above driver as it has code to support the 8811cu/21cu chipset, the same as this driver so there will be a complict and things won't work as expected.
Can I install my TP-Link Adapter on wlo2 interface?
It is possible to set and lock a wifi interface name but that is not a function of the driver. I can show you how if you wish.
Regards
Thanks!

So apparently I have a Realtek internal wifi adapter. I want to switch this to my external Realtek wifi adapter. Is there a sequence of commands to let me do that?
Preferably, I would like to turn off wlo1 and turn on wlo2 and vice versa. (with wlo1 interfacing my internal card and wlo2 interfacing my external adapter)
So apparently I have a Realtek internal wifi adapter.
It appears that you do. Before we work on anything else, we really need to get rid of that old driver you have installed. Run the following:
$ sudo dkms remove -m 8812au -v 5.6.4.2_35491.20191025 --all
Next run and post the output of:
$ dkms status $ lsmod
Next reboot and then run and post the output of:
$ iw dev
That is enough for now.

Good. It appears the old driver has been uninstalled.
It appears that your internal wifi card is support by the in-kernel driver RTW88. The interface leads me to think it is working fine. It can be turned off, we just have to figure out what to blacklist but first, let's try to figure out why an interface for your usb adapter is not showing up.
I see that secure boot is off. It is not clear to me why we are not getting a wifi interface for the adapter. Let check again:
$ sudo update $ sudo upgrade Make sure the usb wifi adapter is installed in a usb port. $ sudo reboot $ iw dev (port the results)

The packages that got upgraded were browsers.
Something could have went wrong during the installation so maybe we should start over. Let's uninstall the driver from this repo and try again.
Go to the driver directory and then I'll provide the installation steps here:
cd ~/src/8821au-20210708 sudo ./remove-driver.sh delete the driver directory and reboot sudo apt install -y build-essential dkms git mkdir -p ~/src cd ~/src git clone https://github.com/morrownr/8821au-20210708.git cd ~/src/8821au-20210708 sudo ./install-driver.sh reboot iw dev (post the results)

Did you run the following lines?
make clean
make
sudo make install
sudo reboot
I was hoping to see the output of the second line so as to see if there are compile errors.

That is a clean compile, exactly as we want.
I have no idea why we are not seeing a wifi interface for your usb wifi adapter. Maybe we need to clean house again and reinstall and turn on some logging:
cd ~/src/8821au-20210708 sudo ./remove-driver-no-dkms.sh make clean sudo ./install-driver.sh sudo reboot
Do you know how to turn on the logging?
No I dont know how to turn on logging.
I was looking into the official drivers provided. They dont have a linux driver on the website but then I thought that the Mac driver might have more information on the type of hardware on the adapter. I havent investigated properly. It maybe of help?
Leaving the link down below https://www.tp-link.com/in/support/download/archer-t2u-plus/
No I dont know how to turn on logging.
cd ~/src/8821au-20210708 sudo ./edit-options.sh
In the options line, change rtw_drv_log_level=0 to rtw_drv_log_level=4
save and reboot
You can save a log file that only includes RTW log entries by running
the following in a terminal:
sudo ./save-log.sh
The name of the log file will be ```rtw.log```.
Paste the ciontents of rtw.log here.
Tell which distro you are using.

Well, that is the kernel, not the OS. It might help if I know the OS (distro).
8821au: module verification failed: signature and/or required key missing - tainting kernel
That is not necessarily the problem but I can't say it is not at this point.
I will try to install the driver and operate my adapter in a VM. I'll post the results here. Maybe that will help
Did you see the fix for #47 ?
I am using xubuntu 20
This driver should work for xubuntu 20.04 if it was using the original version of the kernel that shipped with it which I think was 5.4 but you are now using the kernel from Ubuntu 22.04 and many parts of the dev system have changed so this is kind of a hybrid installation which makes it very difficult to work on. Is there any possibility of getting you to backup your important files so you can do a clean installation of Xubuntu 22.04?
Regards

No. Computers can have several wifi adapters and cards running.
If I have time this afternoon, I am going to reread this thread to see if anything comes to mind.

(WARNING! Diff between built and installed module!)
Never seen that before. Your issue really has me stumped. I'll keep an eye open but, for now, I have no idea what to try next.
The router is working with my system now. I have no idea how.
So in that sense, this issue seems to be solved.
SUMMARY:
I had the latest version of the linux kernel (5.15) but my system was ubuntu 20 something.
I updated my system from ubuntu 20 to ubuntu 22 and installed the driver and that seems to have worked.
