Title:
8086:4220 WiFi (signal strength and connection) drops intermittently:
12.04, Intel 2200BG (ipw2200)
Status in linux package in Ubuntu:
Won't Fix
Bug description:
This is a continuation of:
https://answers.launchpad.net/ubuntu/+source/gnome-nettool/+question/182997
The problem had persisted after that ticket expired, but it's only now
that I have the laptop in my hands and free to troubleshoot.
To recap, the basic issue is that there's something about the way the
Intel 2200GB wireless card on the ThinkPad T43 interacts with Ubuntu
(now upgraded to 12.04) that makes the Wifi connection drop
intermittently and signal strength vary. On my Mac laptop on the same
Wifi network, the signal strength is steady and the Wifi connection
never drops.
I've completely removed Network Manager and am using wicd. I've turned
off IPv6 and Wifi card power management.
