OK, and your directly connected computer is working?  Is it running Linux or
Windows?  If it's working, we know that DHCP is working properly on the DSL
router, and it's correct that it should appear as the DNS IP.

OK, so that's the _internal_ address of the router.

You're not kidding.  Siemens seems to have closed it's whole home networking
line.  Are you sure of that model number?  Are you sure it's wireless? 
(Sorry, but one has to ask!)  

Plug the system you're having trouble with into the router with an ethernet
cable, make sure you have a connection.  Then do:

cat /etc/resolv.conf
cat /var/lib/dhcp*/*.leases 

(for dhclient3 it's actually /var/lib/dhcp3/dhclient.leases, but it depends
which client you're using - that should get most of them).

Then try to connect wirelessly and do the same.  Compare the results.  They
should be exactly the same except for the metric & iface columns in the
"route" output, the actual IP issued in the lease, and the interface the
lease is for.

If you don't get an IP at all wirelessly, then try: "dhclient ath0" (or
whatever the wireless iface is) and report back.
