After upgrading to OpenSUSE 12.1 from 11.4 I had very strange issue with ny Wi-Fi
Right after start my wireless connection works with full acceptable bandwidth about 20 Mb/s. If I start IPTV or other bandwidth-greedy application bandwidth degrade to 1 Mb/s. And doesn’t rise till restart. Ethernet works perfect.
My box is HP 530 Laptop with iwl3945.
I tried OpenSUSE 12.1 Live KDE and got the same issue so it is general problem.

There are no iwl3945 experts here. If you can repeat this without tainting your
kernel (no proprietary modules) and you have a better description, then post on
the linux-wireless mailing list (linux-wireless@vger.kernel.org).
If you have another host available on your LAN and can duplicate the problem
with netperf without involving your ISP, it would be even better.
If you open a terminal and unload/reload iwl3945 with modprobe -r/modprobe, does
that restore full speed, or is a reboot really needed?
Have similar problem, weak and flaky WLAN connection on a new Samsung Chronos with:
The reception is very weak (with frequent disconnects) compared to running windows, or compared to my old laptop (Samsung X20 with PRO/Wireless 2200BG [Calexico2] Driver: “ipw2200” and running 11.4).
I did a data collection with collectNWData.sh if someone is interested. I’m still looking for a solution.

The brcmsmac driver is maintained by Broadcom. None of the b43 developers, or
anyone else, know very much about it. You should post your complaints on the
wireless mailing list (linux-wireless@vger.kernel.org) with as much detail as
you can provide.
