Solve : Cannot connect to Internet?

Answer»

Hi all, really hoping you guys can shine some light and lead me out of this dark tunnel.
Basically I cannot get my desktop to connect to internet using WIRED connection.
Here are specifics and steps I have already taken. (Apologize now for LENGTH but been trying for a WHILE now)

Specs:
Intel Core 2 duo
Asus P5n-E SLI mother board
4GB Ram
80GB SATA HD
Windows 7 Home Premium
NiC Card Realteck TRL8139

Problem:
A few weeks ago could go on line no problem, then a day later couldn't connect. (got no connectivity warning)
Figured it might have been an update that caused an issue, but first I reset modem (Verizon FIOS) and switched Cat5 cables and ports, no avail.
Tried a system restore... no good
Tried installing new drivers for NiC card... no good
Disabled NiC card (as it was onboard MB) and installed a new PCI one.. also no good
Tried ipconfig /release /renew received error, I did not have a valid IP address
Finally decided to just wipe computer since I wanted to go to 64bit Win7 anyways hoping a new install would help.
Got new OS loaded. Still no connection
I tried a static IP,... no good
I unchecked the TCP/IV6 protocol (since I read on another forum that had been causing problems)
I reset the TCP/IPv4 back to automatic
I reset the WINSOCK and TCP/IP stack and still no connection
I do however now have a IP address, but still cannot connect to internet.

Any help or suggestions would be great, as I am on the verge of shooting this thing with a sh** gun

Thanks all
Hi I'll try and help here.

For one thing, you always have an IP address no matter what. .

For second, is there a reason why your warning is saying (no connectivity)?


Also try this:

1. try resetting the modem, disconnect the cables, let it sit for 2 mins, then retry. Tried unplugging everything. Even took it from my dads to my house (both of us have fios.
And when I hit ipconfig it didn't show anything for an ip address. Now it does after doing all the THINGS I've listed. no connection warning was down on task bar, and when I open the network sharing center it shows and says no connection.
Did I answer question or just made more confusion? Anything you want me to try our specs want me to post I will.
Thank you very much for taking time
Dear All Here solution of this error.
BROADBAND connection uses dialer to connect to the Internet. This dialer uses Authentication when connection, either by post paid or prepaid. You need username and password when connection using Windows 7. Good thing about Windows 7, it has it's own driver to detect broadband modem when it's plugged in.
When connecting to the Internet and an error 651 pop-up, then there is something wrong with the network. The driver for RAS PPOE file "rasppoe.sys" located on c:\windowssystem32drivers folder is the cause of the problem.

I tried replacing the "raspppoe.sys" copying it from a working Win7 and it didn't work
(Also I never got that error. (error 651 pop-up)
OK this is just weird and frustrating. I decided to try and reinstalling the MOBO drivers. So I SHUT down computer and rebooted and entered the BIOS to re enable the onboard LAN card (the one that originally didn't work) since I was going to reinstall the drivers. But before I could reinstall drivers, after the computer rebooted shazam it connect to internet using the original onboard LAN card?!?!?!

At this point am just happy it is working, but really am not sure how or why it is.

Thanks all for the help and suggestions. Will let know if it continues to work or if it goes out again.
