Bug 116779 – extraordinarily bad performance with ipw2200

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Voltron Rex 2005-12-26 06:53:50 UTC]

Hello

I'm using a Fujitsu-Siemens laptop that has an ipw2200 wireless card. When connecting to the Sitecom wl-114 wireless router, I get terrifyingly poor performance. Initially, things are fine, but usually within 10 minutes I can no longer use the web at all. Generally, I receive 404's for every request. Using ICQ also has large problems; I get disconnected quite often. If I don't get 404's, I have to wait about 3 minutes for each page to load. No exaggeration!

I get this sort of stuff in dmesg:
ACPI: PCI interrupt for device 0000:01:0d.0 disabled
ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, git-1.0.8

Dec 26 00:41:18 [kernel] ipw2200: Firmware error detected.  Restarting.

This behaviour has occurred since 2.6.12. I am currently using 2.6.15-rc6, but all kernels (gentoo stable, vanilla stable, vanilla unstable) exhibit this behaviour. Further, both the out-of-kernel and in-kernel ipw2200/ieee80211 drivers exhibit this behaviour. The firmware of the router is up to date (I checked today). I only get this behaviour with this router, as far as I know. However, since it's my home router, it's a big deal!

The current kernel config is attached.

I tried to attach the config, but I keep getting an error from bugzilla. When it works again, I will upload the attachment.

Unfortunately, this is a known problem upstream. Nothing much I can do about it in Gentoo land, sorry...

Hi Brix

thanks for the information. If this issue is known, where is the bug for it? At ipw2200 sourceforge, or b.k.o, or what? Please let me know the bug number.
