[Novalug] DCHP server on different subnet from default gw

I'm typing this from my nifty eee pc.

This is a great device, except that It's a bit of a crapshoot as to whether I can connect to my university's wireless network.  

When things work, they work flawlessly:  DHCLIENT is able to get DHCPOFFER from a DHCP server, and the router then automatically sets the default gateway.

But when they don't work, they're perplexing.  DHCLIENT succeeds, but immediately after I get DCHPACK  and my IP from the DHCP server, I end up with
SIOCADDRT:  Network Unavailable

messages.

>From what I can tell, the default gw is on a different subnet from at least one DHCP server.   The network admins at school have confirmed this suspicion.  

We run a no-fixed-IPs-to-students network, so my plea for a fixed IP was rejected.  The techs reported that there was a similar problem with older versions of Apple OSX, but somehow it was no longer a problem for Apple.

Any ideas on how to overcome this?  It goes without saying that my classmates on Windows and Apple have experienced no similar problems.
