https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218908 --- Comment #4 from Kai-Uwe Eckhardt <kuehro@posteo.de> --- The WN821N behaves really strange. Today ifconfig wlan0 scan showed only three APs instead of about 30 like yesterday. After repeating it several times with 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 debugging on with sysctl -w dev.rtwn.0.debug=1 shows a bunch of messages like this: Apr 29 13:35:31 x201 kernel: rtwn0: rtwn_bulk_tx_callback: empty pending queue 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 queue 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 queue Apr 29 13:36:00 x201 wpa_supplicant[659]: wlan0: Trying to associate with 9c:80: df:85:f7:b9 (SSID='balkonia' freq=2462 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 new about the kernel code ;-) Kai-Uwe -- You are receiving this mail because: You are the assignee for the bug.
