Acer Aspire 3750 wlan stalling

[sarte]

Wlan on my Aspire 3750 seems to periodically stalling. First it works perfectly but after couple of minutes it starts to slow down until it finally almost shuts down. After trying to connect a while everything starts work and the cycle starts all over again.

Problem is not protocol or port related. It also does it with all the different wlan-boxes with wide variety of firmwares.

I'm using Ubuntu 11.04

Problem doesn't exist on windows.

Any ideas how to fix it?

edit: updating to 11.10 seems to fix the whole problem.
