Comment (by anonymous):
I'm also having this exact same problem...
I'm using ubuntu 7.10 and the madwifi driver.
A fix/workaround would be great..
Replying to [ticket:1785 [EMAIL PROTECTED]:
> I just got an ASUS C90S notebook, which has a AR5008X (AR5418) wifi
chip. It runs Ubuntu 7.10.
> I followed the instructions on the Ubuntu site for Macbook C2D
notebooks, as they seemed to have the same support issue with this chip. I
downloaded the SVN version of madwifi r3346 as far as I can tell. Now the
wireless card connects well (including obaining an address with DHCP) but
only when I'm not using any encryption on the AP.
> As soon as I switch on WEP encryption, the card can associate with the
wep-key, but doesn't get an address anymore when using DHCP.
> Sounds like a familiar problem, but I haven't been able to find the
exact same problem in the exising and closed tickets. Problem is that
there doesn't seem to be going anything wrong, but DHCP persistently
refuses to get an IP address. I've listed some stats below. Any idea what
this could be? If more details would help, please let me know ..
