<div>T60 continually failed to associate with a Linksys WRT54g AP. PCMCIA Prism2-based cards worked fine. I tried both the ipw3945 and iwlwifi non-free firmware available using Sidux (Debian Sid).<br />
<br />
The card would configure properly and respond to commands but would not associate.<br />
<br />
The solution was simple, I had disabled ESSID broadcast on my AP. Enabling ESSID broadcast solved the problem. This also solved the same problem with a Linksys WPC11 ver 2.6 with USB interface. The non-free at76c50x firmware worked properly, but it also would not associate without ESSID broadcast enabled.</div>Picothinkerhttps://www.thinkwiki.org/w/index.php?title=Known_Problems&diff=30979Known Problems2007-07-04T19:02:04Z<p>Picothinker: /* Network Problems */</p>
