I tried every solution under the sun for given adapter model but they didn’t work for me.

Here are the outputs:

I tried setting wlp5s0f3u3 up with “sudo ip link set wlp5s0f3u3 up” but it didn’t work

I also tried known rtl8192eu fixes:

wifi.scan-rand-mac-address=no

cat /etc/modules-load.d/modules.conf

blacklist rtl8xxxu

options iwlwifi 11n_disable=1 # disables 11n connections
options iwlwifi disable_11ac=1 # disables 11ac connections
options iwlwifi disable_11ax=1 # disables 11ax connections

and also rebooted computer dozens of times in the process.

I don’t see any device with an Intel chip. Is it possible that the adapter does not work/hardware issue?

aleksandar · April 3, 2023, 11:21am

I have dual boot with windows 10, and there adapter worked as soon as I plugged it in.

jrichard326 · April 3, 2023, 11:24am

Is Windows 10 completely shutdown, hibernation, hybrid sleep and fast start all disabled?

aleksandar · April 3, 2023, 11:37am

Yes. Also i forgot to mention that it sees the networks but with really bad strength and can’t connect to them. Also, led diode lights up instantly on windows but here it doesn’t work at all.

jrichard326 · April 3, 2023, 11:08pm

Have you tried to rebuild the driver since the last update? I would go for the dkms version as long as you have the appropriate Linux headers installed for your kernel and if the PKGBUILD does not pull in DKMS, then install that one as well.

aleksandar · April 4, 2023, 2:53pm

I tried, but still nothing. Today I got Tp link Archer T2U plus wifi adapter, and it worked as soon as I installed drivers for it’s chipset. I don’t know what was the problem with previous adapter, but this one just worked. I don’t know if I should mark this reply as answer, but for the price difference of 5$ I think it is worth it.
