Dear list members, I have an RTL8191SU USB WiFi card (with rtl8192su driver) and unfortunately it looses network connection many times (reproducibly, and only under Linux). Re-connecting to the previous network is also very difficult because the following error messages appear in dmesg during that: [164797.994074] wlp0s26f7u2: authenticate with 90:f6:52:7d:6e:0e [164798.031433] wlp0s26f7u2: direct probe to 90:f6:52:7d:6e:0e (try 1/3) [164798.232411] wlp0s26f7u2: direct probe to 90:f6:52:7d:6e:0e (try 2/3) [164798.433700] wlp0s26f7u2: direct probe to 90:f6:52:7d:6e:0e (try 3/3) [164798.634457] wlp0s26f7u2: authentication with 90:f6:52:7d:6e:0e timed out When I turn the adapter off (in KDE network manager app), wait about ten seconds, then turn it on again, it can suddenly connect again flawlessly. Since I'm not a kernel developer, I don't know the perfect ways to track down these kinds of issues. Anyway, I ran the following command when I tried to connect multiple times and the driver refused: trace-cmd record -T -e mac80211 -e cfg80211 I uploaded the output which you can reach here: http://home.sch.bme.hu/~szotsaki/trace-auth-time-out.dat I also traced out the firware version: printk(KERN_WARNING "Version: %u\n", hal_get_firmwareversion(rtlpriv)); -> Version: 36926 (which is strange because in the source everywhere a v52- like numbers are referenced). Do you have time to fix this issue and if so, can I provide some more useful input? Thank you very much!
