When I realized the kernel was breaking the connection (syslog- 3cycles.txt), I decided to give a try for ndiswrapper + windows driver for my wireless card. I followed the discussion here http://art.ubuntuforums.org/showthread.php?p=9391464.
I removed b43-fwcutter and installed bcmwl-kernel-source + ndiswrapper- utils-1.9 + Broadcom BCM4318 driver for Windows XP. In addition I blacklisted b43, b43legacy and ssb kernel modules in /etc/modprobe.d/blacklist.conf and added "alias wlan0 ndiswrapper" in /etc/modprobe.d/ndiswrapper.conf. The connection is pretty stable, without reconnection. This is not a solution, it is just a work-around to keep wireless working. So I am sending you a syslog with come recurrent events done by network-manager and wpa_supplicant. ** Attachment added: "syslog-ndiswrapper.txt" http://launchpadlibrarian.net/49684102/syslog-ndiswrapper.txt -- [Lucid] wireless connection keeps dropping - WPA TKIP https://bugs.launchpad.net/bugs/481432 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
