i got my X30 now and configured it correctly (hope so)
the dell wlan utility says i have excellent connection to my network.
wlan router (vigor 2500we) ip 192.168.1.1
x30 ip 192.168.1.50
three other desktop have ip -20 to -40

i configured the standard gateway on the x30 to
the router ip: 192.168.1.1, as all other desktops have,
with every pc i can surf the internet,
but i cannot browse with my x30 in the internet.

the only exception is, if i start activesync on my laptop, i can surf with the x30 via the USD connection, which i really do not prefer. why do i have a wlan x30 but cannot use it ?

does anybody have an idea how to solve the problem ?

thx
