Wlan trouble after connected.

Hi there,
I am looking for some information and help to fix my problem.

Since a couple of days I got this trouble regarding my wlan connection.
Here my problem and how it occurs:

Starting windows vista just normal nothing else
windows works fine
than I try to get connected via Wlan (either Router or via Internet USB Stick).
My notebook recognises the new network and either I connect manually or the network will be found automatically. So far so good. After the notebook is connected it immediately freeze and I only can shut down and restart.

The strange thing is, if I start windows vista 'safe mode with network' I can get connected and it works just fine.

After I start vista regularly again, I tried a lot of things and hints. for instance
c:\windows\:sfc/scannow
after finished it says some damaged files are repaired...

does not work for me even after this one it failed.

Hopefully there is someone around who has a clue and can help me.
Many thanks.

Hi.. had you tried to run a windows repair off the windows cd?

no i could not try this one. i do not have my cd with me here at my new place... however, today i startet windows vista again and out of the sudden everything is working fine. do not know what happend over night...

windows update can also find solutions and fix it.. if you are running vista..
to check that on start typpe "solution" and open problem and solution.. see if there is anything there as a result to that fix.

cheers
