Hi,

I am using the iwl4965 driver which is included in the kernel
2.6.25-rc6. Everything works fine (Networkmanager, WPA2, etc.) The only
thing I experience is a very bad performance.
I cannot get more than around 30 kb/s. Also the responses are rather
slow. If I open some new tabs in firefox it takes up to 5 seconds before
there is enough data to render something.
When using wired network its much faster.
The router is also not the source of the problem, with my old airo card
i could get up to 200 kb/s, the macbook running gentoo gets to around
500kb/s.

Any ideas where to start investigation ?

Thanks
Thomas

Hi,

Have you tried using the driver from the 2.6.24* series kernel? I've been
using iwl3945 from tuxonice-sources 2.6.24-r3 without any performance or
stability problems whatsoever.
Good luck.

Regards,
José Pedro

When I switched to iwl3945 I had problems with a very unstable
connection (just stable enough to allow wpa_supplicant to recover),
decreasing effective bandwidth a lot. Enabling every suboption except of
debugging for "Intel Wireless WiFi Link Drivers" in the kernel 
resolved it.

Does it work with kernel 2.6.24?

Maybe you could try wpa_supplicant with debugging enabled?

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -d

or even
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -dd

Hi again,

the problem seems to be related to WEP Encryption. Today I tried in a
WPA-Enterprise Network and it was much faster and more responsive too...

I will give the subobtions and 2.6.24 kernel a try anyway.
Thanks
Tom
