Doc I got to that, but my question is why does my 5242E's "Web Configuration" still show the Teksavvy DNS when I have the XP DNS set to Google DNS ?
It's been awhile since I had that modem with Bell's dumb-dumb firmware, however I am very sure that "web config" refers do settings you have no control over (aka the Internet side of your modem). When your modem connects to your ISP (doing the PPPoE login), the ISP assigns you an IP, and also assigns DNS servers. This is the information that populates that page. You don't have any control over what your ISP will assign, however by taking the good doctors advice you can define your own choice at your computer and use them rather then youre ISPs.
Sounds like you have only have a modem (no router) and configured the network setting in your OS to use DNS servers of your choice, by doing so the domain lookup will be done via that address. It is irrelevant what the modem is set for as those servers are not being used since you have configured a new primary and secondary address at your computer.
If you had a more functional firmware installed on that modem you could configure the local network settings to your choice of DNS server. Any machine that connects to the modem (acting like a modem router) would get a DHCP lease that would also include the DNS settings you wish, saving you the bother of manually change each machine.
