** Description changed: Binary package hint: firmware-b43-installer DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.10 DISTRIB_CODENAME=maverick DISTRIB_DESCRIPTION="Ubuntu 10.10" Linux HP 2.6.35-28-generic #50-Ubuntu SMP Fri Mar 18 18:42:20 UTC 2011 x86_64 GNU/Linux Laptop is a HP Pavilion dv9500 with a wireless hardware switch. Problem seems to occur after intensive wireless use (simultaneous video, IM, IRC and web surfing) or after being on continuously for more than 24 hours. Network manager will indicate disconnection from wireless network (WPA2) and any subsequent attempts to reconnect will not work (nw will act as if interface is down). Attempted modprobe -r / -i of b43 driver, restart of /etc/init.d/network and /etc/init.d/network-manager and flipping physical hardware switch in various orders.
