View Full Version : [ubuntu] Dell wireless unstable after latest updates

May 4th, 2011, 01:12 PM
I'm using Ubuntu 10.04 on a Dell Inspiron 640m (Wireless: Intel PRO/Wireless 3945ABG [Golan] Network Connection, Ethernet: Broadcom BCM4401-B0 100Base-TX, output from sudo lshw -C network below.)

This morning, the wireless connection, has gone down repeatedly, and signal strength looks a bit weaker. There was a period in January when there were similar problems that then improved. Seems like a recent system (perhaps this morning/yesterday) update broke something.
