I have a HP Elitebook 2730p. lspci shows my WLAN adapter as follows:
02:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN
[Shiloh] Network Connection
When I am at home (WPA2) everything works perfect. But when I am at work
(WEP 128 with shared key), I never get a working connection. The strange
thing is that all my other machines at work (all running Ubuntu 8.10 but
all with a different WLAN adapter) get a connection without any problem.
Therefore my guess is that something is broken in the iwlagn driver that
does not like WEP or shared keys. But I am no expert here at all. Here
are some more details about the machine where the connection fails:
Here is the output of iwconfig:

When I kill nm-applet and start it from the command line, I get the following
console output after the connection failed:
** Message: <info> New secrets for PFHSO_PWLAN/802-11-wireless-security

dmesg shows the following lines:
