GNOME Bugzilla – Bug 689945
wireless connection drops, asks for unneeded password, fails reconnect, restart req'd
Last modified: 2014-04-25 15:53:00 UTC
Archlinux i686 (2012-11-01) and Gnome 3.6: After running for awhile (several hours) with user interaction and stationary, a wireless connection to local AP fails, and reconnect presents dialog requesting PSK, which it has. Attempts to reconnect fail. Connection automatically succeeds after system restart and sometimes after Networkmanager.service restart (systemd). nm-applet sometimes fails aslo. Previouly filed at: https://bugzilla.gnome.org/show_bug.cgi?id=689366 A reinstall of ArchLinux(2012-12-1)/Xfce4(4.10) with NetworkManager 0.9.6.4-1 produces identical results. Further discussion at: https://bbs.archlinux.org/viewtopic.php?id=152968 with some logs and related bug reports. Hardware is Lenovo S12 Intel Atom 32bit laptop with Broadcom 4312 (B43 and firmware installed). No connection problem on this system running dual-boot WinXp. No other clients of AP having problems with connection. MAC filtering in use. Makes this system useless for Skype.

Correction: 2nd sentence should read After running for awhile (several hours) ***without*** user interaction and stationary
I have dropped Network Manager, installed and tested netcfg and it failed. I have now dropped netcfg and installed WiCd, and it holds the connection
Lost connections, slow operation is most probably driver issue. NetworkManager calls wpa_supplicant that establishes connection and talks to driver. See instructions at https://live.gnome.org/NetworkManager/Debugging/#line-33 to get logs and debug.
NetworkManager has been deprecated on this system. It has been replaced with WiCd, which has held the wireless connection for over 48 hours. The driver and firmware are b43, unchanged. Connection speeds vary, but are acceptable for this inexpensive laptop. Thanks for the excellent link.
