Question : Can connect to internet at work, but not at home

We have a user using a laptop at work (using a AD domain) and he has no problems connecting to the internet.

When he takes his laptop home, he is unable to connect to the internet (via wireless and cable modem).

His IP settings on his wired and wireless connection are set to DHCP.

If he connects to the company VPN, he can get internet access at home.

When he does a nslookup at home, his laptop is trying to connect to the work internal DNS servers.  

I've been beating my head against the wall with this one... any ideas?

Answer : Can connect to internet at work, but not at home

Check that the user can ping his router at home.
I would get the user to run a cat5 cable to the router and be sure its working before attempting wireless.

make sure also that in the network settings

control panel -> network connections --> connection name --> (right click) properties -->TCP/IP -->properties

both general and alternate config should be set to obtain IP address automatically.
