Hi Magnus, Excerpts from Magnus Therning's message of Fri, 18 Jun 2010 00:22 +0100: > It's a broadcom card, using the b43 driver.

Any hints on what I can do to test that > myself? I used to use b43, but now I don't. I had similar situations with other wifi cards. 1. Two or more access points in the vicinity are using the same channel. If you're able to change the channel, chose one not used by others. The reasons are more or less obvious. 2. If other computers are using the same access point, and my connection is getting dropped I indeed intentionally lower the bitrate: iwconfig wlan0 bitrate 24M (or lower) - it works, but the reason is unknown, I haven't investigated it. You may want to install wavemon program to monitor your connection [0], there is a package in AUR too [1].
