Windows 7: win 7 vs. modem

win 7 vs. modem

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 Windows 7 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 Windows 7 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 Windows 7 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 Windows 7. 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.

You shouldn't need any "driver for this RCA modem", if you are using the ethernet connection from the PC to the modem. (You'd need drivers for the Realtek Ethernet controller, but I assume that you already have those.)

On rare occasions, I find it necessary to reset my RCA modem. There's a rest button in the rear, that is recessed (use a paperclip end to press it). Sometimes I have needed to power cycle the modem completely, which requires that its backup battery be removed.

Do you own the modem, or is it leased from your cable provider? If it's leased, and Canadian cable companies are like US ones, they may be prepared to exchange it for a new one with no hassle.

There's no DNS server addresses in your IP configuration; without that, you won't be able to browse the web.

You could also test, if your network connection is a OK:

Code:
ping 192.168.100.10 (note: your computer's IP address)
ping 192.168.100.1 (note: your router's IP address)
The result should be something like this:

Ping statistics for 192.168.100.1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1ms, Maximum = 3ms, Average = 1ms
If the results are a bunch of "Request timed out", you may have a misconfiguration for the network card or a bad Ethernet cable. It is also possible that you'd need a cross-over cable.

If you can ping the gateway, then try this:

Code:
C:\Users\username>nslookup sevenforums.com
Server:  your default DNS server name
Address:  Your DNS server's IP

Non-authoritative answer:
Name:    sevenforums.com
Address:  184.172.52.99
If the domain name does not resolve to IP, use the above IP address and try to ping it. If you have Internet connectivity, you should have similar results as this:

I've overlooked your DNS settings...

That seems to be either IPv6 address, or leftover from the DSL settings. In either case, configure the IPv4 as shown in the image:

Check that under "Advanced\DNS" tab, there's no DNS server listed:
