Comment 4 for bug 176602

I can confirm a rather similar behaviour on my D630 with Gutsy. The ip3845 does not work in a stable manner and the iwl3945 is not able to join WEP protected access points.

Here is an excerpt form the syslog:

It seems to work fine with access point without any encryption method.
