It happens randomly. There is no definite way to reproduce it. Here are some info of the wlan configuration copied from NetworkManager system-connection files. [connection] type=wifi [wifi] mode=infrastructure security=802-11-wireless-security [wifi-security] key-mgmt=wpa-psk [ipv4] method=auto [ipv6] method=auto ip6-privacy=2 I also tried to switch to different channels on the router settings, but not helpful. Other wireless devices have no stability problem when connecting to this router, but I also haven't observed another router which this laptop with b43 has problem with. Here are some system information. $ uname -a Linux hong-MacBook 3.18.1-3-ck #1 SMP PREEMPT Mon Dec 22 14:40:44 EST 2014 x86_64 GNU/Linux # lspci -vvn | grep 43 -A7 04:00.0 0280: 14e4:4331 (rev 02) Subsystem: 106b:00ef Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- SERR- -------------- next part -------------- A non-text attachment was scrubbed...
