TP Link Ac 600 on elementary 7.0

[anballes]

Hi All

I use elementary OS on Dell Latitude E7440 (its only have 2.4 Ghz wireless card) and bough an new USB wireless card from TP Link, the TP-Link AC600 wireless Realtek RTL8811AU (its 5 Ghz)

I download the drivers and setup everything, finally the network interface works and can connect to internet.

But the previous process ( im no sure) change something al kernel level then when the system update everything roll back the kernel to the new one and previous setup for TP link dismiss.

I dont know how setup the wireless card and preserve it in front of new kernel changes.

Anything is welcome and thanks in advance,

Andres

When you install a driver manually, it relies on the specific kernel you have to generate code to talk to it, and it's susceptible to failures when you update the kernel, so the driver is kept in a place that is specific to that kernel, otherwise the system would just start spewing lots of errors due to the faulty driver. To solve this, it's common to suggest to stick to hardware that contributes their drivers directly to the linux software. In you specific case, there is a package available to add drivers in a way that they get reinstalled automatically when a new kernel is installed (this uses a process called DKMS). After looking for info on your specific card, I found out that if you run in a terminal the command sudo apt install rtl8812au-dkms it should, after installation and reboot, allow you to use your usb wifi card with current and future versions, as this will install the driver using DKMS.

Yeah, kernel seems to be too new for that, you might have to download the .deb package from here, running sudo apt remove rtl8812au-dkms to remove the one failing, and installing it from the downloaded deb (You can use either the Eddy app available in the App Center, or via the dpkg tool in console)

[anballes]

Thanks, the sudo apt remove rt18812au-dmks was successful but the package installation from Synaptic got an error:

Weird, the link I shared gives you a .deb called rtl8812au-dkms_4.3.8.12175.20140902+dfsg-0ubuntu20_all.deb (for the ubuntu release codenamed mantic) but the log you shared is for rtl8812au-dkms_4.3.8.12175.20140902+dfsg-0ubuntu17_all.deb (for the ubuntu release codenamed kinetic) You need the one from mantic because it is the one compatible with the 6.x kernels

Hi Mario

I think I will opt to do a fresh install of the OS and boot from scratch, if I go this way what would you suggest me to do a clean install of the drivers and not fill the system with software patches ?

[anballes]

Back again guys

I decided that I will do a clean install of elementary 7 and the first thing will be to install the driver card, but please could you confirm me what would be the steps to just installed the O.S, install the card but remain persistent so that with kernel updates does not stop working ?

[anballes]

Hi All

Please, any clue ?

Thanks in advance.

Hi Jeremy

Thanks for the contribution.

Unfortunately I got this error during the installation:

Later on, try again to run the make with flag suggested but nothing , finally when I ran again the command:

Any clue ?

[jeremyb31]

sudo apt install linux-headers-$(uname -r)

[anballes]

Great, you right.

My problem was that in a fresh install of elementary it does not download the kernel source, so as a step before s_udo make dkms_install_ you would have to verify the kernel and that the OS has git.

Thanks to all
