Hello again!

I got another strange problem with my 500gP...
It concerns the DNS behavior.

I connect to the router with 2 machines: 1WinXP with LAN Cable - everything works well.
But when I connect via WLAN with my Laptop, I cant get DNS resolving.
I can ping the DNS Server and any other IP in the web, but pinging for example www.google.com gives me a timeout.
One time resolving seemed to work (dont know why...), but i still got a timeout.

Ping www.google.com [66.249.85.99] mit 32 Bytes Daten:

Zeitüberschreitung der Anforderung.

ipconfig /all displays everything correct, including the DNS Servers.

Has anyone some experience with this behavior?
