I was pretty sure that the routes where okay - I did just double check 
and it's all fine: http://files.derickrethans.nl/Screenshot-5.png

I've check that resolv.conf is correct (same as on the laptop that uses 
the same WLAN), but still no dice. It gets the IP address just fine 
through DHCP, but *no* packets go over the line - I can't even ping the 
gateway (though I can ping the device's IP).

Now I do remember that when upgrading my kernel it mentioned something 
about wlan modules - but I do not remember the extend of those messages.

Any other ideas what the issue could be? I am still on 2007.7 - as how 
it came with the phone, but I've opkg update & opkg upgrade'd it all 
today. Any other ideas?
