Hi Kevan,

As I said check your /etc/resolv.conf. I believe most of the applications accessing internet should honour it.

Also make sure your dhclient.conf file ($ find /etc/ -name "dhclient.conf") has these entries -

#need this next line with your ISP's Primary and Secondary DNS
prepend domain-name-servers x.x.x.x, x.x.x.x;

#if it already has this entry, leave it as it is. Otherwise, put 'em.
request subnet-mask, broadcast-address, time-offset, routers,
	domain-name, domain-name-servers, host-name,
	netbios-name-servers, netbios-scope;

These files get overwritten everytime when you execute -
$ dhclient eth0;
to get dynamic IP from your router.

Also sometimes, new driver for your specific network card (wireless, wired) get loaded in the new distribution. In that case, if it doesn't work, you need to replace the new driver with the old one (usually located in /lib/modules/`uname -r`). This symptom is apparent when you can't get your interface (eth0/1/2 etc..) to work.
