Wifi instability with TP-LINK Archer TX20E

nikthechampiongr · January 1, 2024, 2:32am

Hello, I’ve been having constant issues recently with a lot of instability with wifi where my connection just dies for no apparent reason and sometimes gets completely disconnected from the network and can’t reconnect until whatever service is handling the network is restarted. So far I’ve tried to switch from NetworkManager to iwd which made no real difference. Something to note is that currently tp-link on their website provides the rtl8852BE driver for wifi which is not supported past linux kernel versions over 6.0.0. The driver currently in use is rtw89, from what I understand from the output of lsmod the driver currently in use is rtw89:

rtw89_8852be           12288  0
rtw89_8852b           376832  1 rtw89_8852be
rtw89_pci              86016  1 rtw89_8852be
rtw89_core            688128  2 rtw89_8852b,rtw89_pci
mac80211             1662976  2 rtw89_core,rtw89_pci
cfg80211             1376256  3 rtw89_8852b,rtw89_core,mac80211

I should also note that using lts kernel 6.1.69-1 somehow breaks everything even more with the adapter not being detected at all.

Here is the inxi output:

I just realized that there is a specific hardware section. I don’t think I can move this however.

Not sure if this helps.

github.com

lwfinger/rtw89/blob/main/README.md

rtw89
===========
### A repo for the newest Realtek rtw89 codes.

This repo is current with wireless-next up to Nov. 2, 2023.

This branch was created from the version merged into the wireless-drivers-next
repo, which is in the 5.16 kernel. IF YOU USE DRIVERS FROM THIS REPO FOR KERNELS
5.16+, YOU MUST BLACKLIST THE KERNEL VERSIONS!!!! FAILING TO DO THIS WILL RESULT
IN ALL MANNER OF STRANGE ERRORS.

This code will build on any kernel 5.6 and newer as long as the distro has not modified
any of the kernel APIs. IF YOU RUN UBUNTU, YOU CAN BE ASSURED THAT THE APIs HAVE CHANGED.
NO, I WILL NOT MODIFY THE SOURCE FOR YOU. YOU ARE ON YOUR OWN!!!!!

Note that if you use this driver on kernels older than 5.15, the enhanced fetures
of  wifi 5 and wifi 6 are greatly crippled as the kernel does hot have the capability
to support the new packet widths and speeds. If you use such a kernel, you might
as well have an 802.11n (wifi 4) device.

Alright I’ll attempt running this for a few days and tell you if it helps. Thanks for the help.

nikthechampiongr · January 2, 2024, 8:21pm

Well so far no other problems so I guess I just need the git version of the driver which isn’t ideal but much better than my previous situation.

ricklinux · January 2, 2024, 8:41pm

Lets hope it stays that way at least for a while. I think this chip is pretty new.

Edit: I have a number of tp-link wifi Pcie-e adapters and i just picked up a newer one not installed yet which is an Archer also but don’t remember the model off the top of my head. It is the AX standard though.
