Are you certain that your DSL modem is plugged in to the correct port on the router with the correct cable? You said that you plugged it into the "Internet" port, which looks like it is the WAN port, according to the
manual. Depending on your DSL unit, that could be a cross-over cable or a standard ethernet cable. If it came with the modem then it
should be the right one.
"dialed into the router via browser" By
dial I assume you aren't using a POTS modem, yes? Blending terms can make that confusing. If you can connect to the router, then you have an IP address and are connected to your local network and the problem is at the gateway. What information to you have about your Internet connection?
Assumption: DHCP ISP IP
On the router's configuration page there should be an entry for the IP address it received from your ISP. Did it get one? Did it also get entries for DNS servers? Are they the same or similar entries as you would get in Windows when the DSL line is plugged straight into your computer (
via ipconfig /all at the command line)?
On your PC, what happens if you
ping www.google.com and
ping 216.239.63.104? If you can ping the IP address, then it would be a DNS problem. Neither and you still aren't getting past the gateway.
