Glad that one helped.  (this really needs to be fixed)

I think there is way to configure different network profiles and then
select which one you want to use.  Have not done this myself but I found
this which may get you going the right direction.

The best place to look is using netstat -rn which will list your routing
information.  Make sure the default gateway is set correctly and that
you can ping it.

Is it possible you are using a duplicate IP address?  If you happen to
grab an IP that another machine is using the gateway would send reply
packets to the other device until its arp cache is flushed or forced to
re-arp at which time your machines MAC address would be added to its arp
cache.  Then you would have access through the gateway.

Check the man pages on the system.  Lots of good info there.  Make sure
you have resolv.conf configured correctly.  It needs to contain the DNS
servers IP addresses either for your ISP at home or for your works DNS
servers depending on which network you are on.

DHCP will usually provide that information if you are able to use DHCP.
