And since you are not using a support service I'll offer a test I use to sniff out if this is hardware or software.
But first, since this machine had DSL it's possible you had some DSL MODEM driver installed. I don't see where you removed that. Sorry I can not tell you how to. I've seen dozens of such PPPoE DSL software over the decades so I can't guess which method to use.
With that out of the way, I'm also hampered by the lack of a quoted "error message."
Moving onto the test I use. I boot a LiveCD called Ubuntu and see if I can get on the internet. No install needed, no learning Linux either.
More at ubuntu but for 99.99% of the time I boot the LiveCD and then pull up FireFox and I'm in. If there is hardware or windows software issues you have to tackle that.

In parting I've lost count of posts like yours when the antivirus expires.

Hi y'all. I recently switched from Bell DSL internet to Teksavvy cable service. No network connection/no internet service would function on my computer. A Roger's Cable tech rep came to my apartment. His Windows XP laptop worked fine using my ethernet cable connection, which would not function on my W7 64 bit computer. The Rogers rep told me to take the one year old (3.3Ghz/ram) computer tower to where I bought it from (Canada Computers). The Canada Computers service rep hooked their DSL ethernet LAN cable to my W7 computer, and it worked fine. Back at home and using cable, the internet finally worked (after I changed my log-in user to administrator). After a few days of surfing, the network connection died again. All I get now is "Error message 651; The modem has reported an error." RCA model DCM425 is the modem. Window's "Diagnose" and "troubleshooting" functions came up with nothing. I thought it might be a virus, so I re-installed W7 a few times. Furthermore, using a different computer at a shop, I downloaded a driver for this RCA modem, but the files were not recognized by W7. I've tried doing hard resets with the RCA modem, turning it off/on, all to no avail. I even tried some advice from forum.techguy.org to command prompt "ipconfig/release" and "ipconfig/renew" in order to get the modem and computer communicating, but still no luck. I phoned Microsoft tech support, and they want $100 to "solve the problem." Teksavvy has no answers; Rogers, the same. So too for Canada Computer.
