[SOLVED] Can't get any wireless connection from my TP-Link Archer T3U

byjove01 · 2023-03-06 21:24:00

Hello,

I had to remove for some times my TP-Link Archer T3U AC1300 until now, but despite putting it back to my computer, my computer still does recognize it but doesn't get any internet connection from it. When I ask to connect to my WiFi network, it gets stuck on "interface connection" and suddenly gives up on a "wlp3s0f0u4" error with description "Can't find WiFi network". I remember this device to perfectly work until I remove it, so I don't think it died.

I'm using this driver https://aur.archlinux.org/packages/rtl88x2bu-dkms-git and my Arch version is 6.2.2-arch1-1.

lsusb -v makes me sure my USB device is detected.

Here's the output of journalctl -b : https://pastebin.com/SMAtRcZY.
Also, a bit off-topic, it happens that my desktop freezes for several seconds after doing something. Is that related to that lack of a Plasmoid logged in the journal?
Thanks in advance.

Does nobody have an idea? I really need to get this solved. I tried again to use it with the classic way, the error is still here.

- Don't bump
- Post the actual journal, not some random tail.
- Search the forum for rtl88x2bu and try the LTS kernel, out-of-tree modules fall incompatible w/ major kernel updates rather frequently. At least rebuild the module from the latest git.

- If I need help for a technical issue and that nobody replies me, what should I do if not bump? Wouldn't I get blamed if I created another topic? No disdain but I don't see any prohibition of bumping into the forum rules by the way.
- I watched for a longer time the comments of the driver package and it seems like blacklisting "rtw88_8822bu" was the best way to solve this issue. It seems like the kernel was the one bullying my Wi-Fi device.
Thanks anyways.
