Is your office DHCP server configured correctly?

The subnet declaration needs a "option routers" block.
My ISC dhcpd.conf file has these lines:

subnet 10.10.10.0 netmask 255.255.255.0 {
    option routers 10.10.10.1;
    pool { range   10.10.10.100 10.10.10.150; }
}


To debug, you can run tcpdump on your lan interface and watch
the dhcp traffic for anomalies.
