Windows 7: Internet Inactivity

Internet Inactivity

Hi guys! I'm having internet problems that I have tried to fix for two days now and just can't get anywhere with. I have tried everything I can think of and every forum I can find and nothing has helped. I'm hoping the experts here at the Seven forums can help.

First a rundown of my system:

I have a Comcast Cable modem that is plugged into a Gigabit DIR-655 Router. From the Router, I have two, sometimes three, laptops connecting wireless and then my PS3 and computer connected by a wire. My computer is running legal Windows 7 with everything updated.

About two days ago, when I got home from work, my internet was down. Every once in a while this happens so I proceeded to restart my router. That didn't fix it and so I went from there and it just got worse. Here is a list of everything I've checked.

Reset/Restarted Router
Reset/Restarted Modem
Checked that I had the newest NIC driver and the newest firmware on router
Made sure that all the laptops and PS3 have connection (They do)
Tried to restart computer.
Tried booting into Ubuntu to see if I could get internet there (I CAN'T)
Tried uninstalling the Network adapter driver and reinstalling it
Tried pinging the NIC (270.0.0.1) It pings fine
I have tried plugging the ethernet wire that was going into my pc into my ps3 and one of the laptops (It connects both of them)

What happens when I first boot into Windows is that it says I don't have a network. The little diagram just shows the adapter going into internet. When I unplug the ethernet cord from the back of the computer and plug it right back in, then it shows a network but an unidentified public network.

I'm so confused by this because I've pretty much killed of the possiblity of a hardware problem but at the same time since it is happening in Ubuntu and Windows 7, it doesn't seem like it could be a software problem. Maybe it conveniently has a software problem with both? Any help would be greatly appreciated. I don't have a ipconfig /all log yet since I'm at work. I'll try to post one this afternoon.

Is this a built in NIC? If so you may want to go into the BIOS and play around with the NIC settings, maybe reset your BIOS.

Yes it is. The NIC is on my Gigabyte P55A-UD3 Mobo. It is a Realtek. I will try when I get home from work. Any other suggestions? Thanks.

If you have tried the network cable on different devices and it works on the other devices that rules that out, but ya never know, you may go ahead and try a different network cable.

And if ubuntu and windows both have the same issue, its pointing to your nic being bad, or misconfigured in the BIOS.
