Intermittent wireless Issues...

[Kevin Kempter]

Hi List;

Sorry for the cross-post, I'm not sure if I should ping the KDE list or the 
Fedora list so I posted to both.

I've just acquired a new (last years model) Sony VGN-SZ430N/B laptop. I 
installed Fedora 7 and initially everything worked fine - including the 
wireless. However when I'm at my current client's site (they have a WEP 
shared key wireless) I get the following behavior:

1) upon boot my wlan0 connects without issue.
2) as long as I work in my cube life is good
3) if I travel around the office at some point the wireless looses it's 
connection
4) once the wireless connection is lost I cannot re-connect by any means other 
than a reboot. The reboot works every time. If I try the 'Network Device 
Control' it simply fails, If I go to the Knetwork Manager (I'm running KDE) 
right click and choose the right connection I get prompted for the WEP key 
(even though it's saved in my KDE Wallet) and the connection fails.

Here's the versions of KDE/Knetwork Manager I have installed:
knetworkmanager-0.2-0.1.svn20070815.fc7
kdebase-3.5.8-3.fc7

Any thoughts on what might be the issue? Ideas how to debug this?

Thanks in advance
