Comment 7 for bug 272156

Hi Dmitry,
I took your advice and set my Linksys WAG160N to disable 802.11N and
now I can set the ESSID. However, while it associates without the
freeze and I can scan with iwlist and see all the available
neighbourhood Cells... dhclient refuses to give me an address.

At least the system doesn't freeze :^)

I see the following in the log:

root@dug-desktop:~# dmesg|grep wlan

I'm not sure what the IE unknown means.

No lease offers are seen:

No DHCPOFFERS received.
No working leases in persistent database - sleeping.

Setting a static IP doesn't work either :^(

This is using a Linksys WMP300N (Atheros 5416) and Ubuntu 8.10 beta,
2.6.27-5-generic.

At least you cured the freezing :^)

Cheers,

Doug
