random network disconnects. network maniger / Realtek.

mrhooman · 2025-05-12 19:11:54

Hello, a while ago I got a lenovo yoga 3 in 1 and I installed arch on it because thats what I daily run. the issue that I have been having with is that sometimes the networks I am connected to will randomly disconnect and prompt for a password (the kde network login pops up and says the password was wrong). I can re connect by just putting in the password again, sometimes I have to do it multiple times before it works. I am relatively good at arch but I have steered clear of trying to deal with this because Realtek scares me.

it seems to mostly happen when the wifi chip is not under heavy load and is just idling so it might be something with it going to sleep. the card is weird as well sometimes the difference of me sitting up vs slouching is enough to disconnect it.

lsmod | grep rtw

Depending on which module is used (rtw88 ot rtw89) try

rtw88_pci.disable_aspm=Y rtw88_pci.disable_msi=Y rtw88_core.disable_lps_deep=Y  pcie_aspm=off

or

rtw89_pci.disable_clkreq=y rtw89_pci.disable_aspm_l1=y rtw89_pci.disable_aspm_l1ss=y  pcie_aspm=off

Also maybe see https://aur.archlinux.org/packages/rtw89bt-dkms-git

Sanity check:
Please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Also check your system journals for indications that NM is just roaming.

note: SwapAdder.service is a scetch thing I made to make more swap. ik there is a better way but if it aint broke dont fix it

Please use [code][/code] tags. Edit your post in this regard.

But there're no concurrent services so look for roaming patterns and test the relevant module options.
