https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D218908 --- Comment #4 from Kai-Uwe Eckhardt <kuehro@posteo.de> --- The WN821N behaves really strange. Today ifconfig wlan0 scan showed only th= ree APs instead of about 30 like yesterday. After repeating it several times wi= th the same result I shutdown, rebooted and now it shows 30 again but an AP in= 3 meters distance is sometimes present and sometimes missing. Turning debuggi= ng on with sysctl -w dev.rtwn.0.debug=3D1 shows a bunch of messages like this: Apr 29 13:35:31 x201 kernel: rtwn0: rtwn_bulk_tx_callback: empty pending qu= eue Apr 29 13:35:31 x201 kernel: rtwn0: rtwn_raw_xmit: called; m 0xfffff8000adac300, ni 0xfffffe00023c1000 Apr 29 13:35:31 x201 kernel: rtwn0: rtwn_raw_xmit: called; m 0xfffff8000aa41a00, ni 0xfffffe00023c1000 Apr 29 13:35:31 x201 kernel: rtwn0: rtwn_bulk_tx_callback: empty pending qu= eue Apr 29 13:35:32 x201 kernel: rtwn0: rtwn_raw_xmit: called; m 0xfffff8000adac300, ni 0xfffffe00023c1000 Apr 29 13:35:32 x201 kernel: rtwn0: rtwn_raw_xmit: called; m 0xfffff8000aa41a00, ni 0xfffffe00023c1000 Apr 29 13:35:32 x201 kernel: rtwn0: rtwn_bulk_tx_callback: empty pending qu= eue Apr 29 13:36:00 x201 wpa_supplicant[659]: wlan0: Trying to associate with 9c:80: df:85:f7:b9 (SSID=3D'balkonia' freq=3D2462 MHz) Apr 29 13:36:10 x201 wpa_supplicant[659]: wlan0: Authentication with 9c:80:df:85 :f7:b9 timed out.

Looks like a good opportunity to learn something n= ew about the kernel code ;-)=20 Kai-Uwe --=20 You are receiving this mail because: You are on the CC list for the bug.=
