Description:
Cannot use some wireless networks with 2.6.23. Can successfully associate and gain an IP on the network, but am unable to then use it.

If I type 'route' at console, the first two lines appear, and the third one always after 10 seconds, it seems to be timing out on something. The third line is the gateway.

Networks that don't work:
* Uni, WPA Enterprise, dhcp
* Another Uni, No Security, dhcp
* State Library, No security, dhcp

Network that works:
* Home, wpa personal, dhcp

Additional info:
* kernel26-2.6.23.1-3
* ipw2100
* disabling ipv6 has no effect
* loopback is up

Will post output of route, dmesg, ifconfig and iwconfig when I get home. Also will test previous versions of kernel26 next monday/sunday if I can to nail down the version, or whether it was something else that has caused the problem.
This task depends upon

This bug really annoys me. I had a similar/same thing with my old wireless router.

New kernel doesn't fix it, though one of the 'problem' networks started working randomly this afternoon after not working in the morning.

I tried 2.6.22, and was able to reproduce it there, so I don't think it's kernel related after all. Something in userspace, or possibly some horribly odd and hard to track bug.

I've got some ideas, which i'll try tomorrow. It may be dhcpcd...

yes dhcpcd can be weird too

Almost definitely dhcpcd, I'll file a bug with the author.

My old wireless router, which I've since given to someone else, exhibited this behaviour frequently. Today I found I could connect fine with dhclient.

Just then, the same problem occurred. Did dhcpcd -k ipw0, then dhclient ipw0, and it's all working again.
