Hi SOUK,These errors are common in FreeBSD 10 for said hardware. Apparently a lot of work went into FreeBSD 11 and it is fixed there, but the fixes never went back to 10.x, so until we migrate to FreeBSD 11, these errors will not go away and the hardware hardly works.There are some workarounds like only using channel 12 (??), but I don't exactly remember, some people had the same issues before and the old threads can possibly help operate the hardware until the major FreeBSD update is done.Cheers,Franco
