My custom built older computer is no longer connecting to the internet (yellow triangle). I can connect with other devices, and verified that the ethernet cable was not the problem.

My connection is through comcast on a technicolor tc8305c. I am running windows 7 home on a 64 bit system.

Are you saying that other systems can connect using this modem-router...but your system does not?  Does the wifi aspect work with your system?

 

Have you tried the wired ethernet connection to other systems?

The wired does work even with the same cable on my other computers. The problem computer does not have wireless.

Start an elevated command mode, and type:  ipconfig (press Enter)

Find your ip address, and type: ping [your_ip_address] (press Enter)

If you have a reply of failure to receive 4 sent packets, your problem is in your computer.

If successful and 4 packets are returned, then type: ping google.com

If that ping fails the problem is in your router/modem. I doubt this is the reason since your other computers can access the internet, but try it anyway.

 

If you are running integrated network connection (the NIC is part of the mainboard) you can try SFC Scannow command. It may or may not work. If no joy, try a system restore from a time point immediately before this all started.

If that fails, and if you have the system drivers for that computer on a separate CD,l try reinstalling the networking drivers.

If that fails, I suggest getting a USB wireless dongle and trying that.
