You must have a bad DNS server; by default, the domain and search
won't be used if the server that you're trying to connect to has a "."
in its name.

Override the values that the router sends you by adding

supersede domain-name-servers "8.8.8.8 8.8.4.4"; ## Google's but you
can set others
supersede domain-name "domain";
supersede domain-search "search";

to "/etc/dhcp/dhclient.conf"
