rtl8812AU_8821AU-kmp-default-20170613_k4.4.74_18.20-2.1.x86_64 with TP-LINK ARcher T4UH on openSUSE Leap 42.2 #230

After buying the TP-LINK Archer T4UH that claims "Linux support" I realized that the driver TP-LINK offers cannot be compiled easily (even after hacking) in openSUSE Leap 42.2 (4.4.74-18.20-default). So I used rtl8812AU_8821AU-kmp-default-20170613_k4.4.74_18.20-2.1.x86_64 from the openSUSE build service (http://download.opensuse.org/repositories/home:/Akoellh:/Kernelmodules/openSUSE_Leap_42.2_Update/x86_64/rtl8812AU_8821AU-kmp-default-20170613_k4.4.74_18.20-2.1.x86_64.rpm). Basically it worked quite hassle-free, but there are some minor issues.

The first day the WLAN AP was close by (about 1m): The WLANs were detected and I could log in. At some point (maybe the AP restarted after reconfiguring) I got these messages:

Another thing that puzzles me is "BSS not found" (I don't understand what it means):

The second day I had the WLAN AP move about 10m away, so the 5GHz was rather weak, but I couldn't see the issues I had seen on the first day.

However it seems the WPS-key on the stick has no effect at all. Can you confirm?

Are these problems already known and fixed?

Throne3d commented 7 years ago

The disconnection problem looks plausibly related to #215. I've been getting intermittent disconnections, with a similar error involving rtw_set_802_11_connect and rtw_chk_start_clnt_join. I'm not sure what triggers it, but when it starts it usually repeats once every 120 seconds. (Moving the device to another port seems to fix it, sometimes?)

sjvudp commented 7 years ago

Could it be some roaming between 2.4 and 5GHz (same SSID), or the access point changing to more silent channels ("self optimizing")?
