Hi,

My windows 7 64bit comp shows its connected to the internet, but I can't connect at all using chrome or internet explorer?

the laptop in house works on the network wirelessly without a problem.

I can ping google.com successfully and here are the ipconfig /all results.

"the laptop in house works on the network wirelessly without a problem.

So wirelessly it works, but your ipconfig shows only the wired connection so I assume the issue is when using an Ethernet cable to connect to the internet, try these pings in the following order:

-ping 127.0.0.1 (to verify TCP/IP drivers are correctly installed)
-ping 192.168.1.6 (it's own IP should reply)
-ping 192.168.1.1 (1st chance of failure)
-ping 74.125.229.250 (pinging directly to one of google's IPs)

lets also test the DNS resolution:

from cmd type: nslookup www.google.com

if it gives a successful answer then your pc should be able to navigate, if it fails to load say google.com try going directly by typing it's IP in the browser URL bar: 74.125.229.250

If still unsuccessful make sure there's no proxy configuration in your browser, that could cause this issue while getting successful pings and DNS resolutions.

I apologize, I meant the laptop which is a different computer is working on the network wirelessly without a problem.

The Desktop is plugged in through the ethernet. and everything looks like it should be working. Here are the results of the ping tests.

I see, have you checked your browser's proxy configuration? also, run a virus and trojan scan on it, some malwares specifically cause this problem so let's discard that possibility.

I believe you are correct, it is a virus, trojan, or some kind of malware. The computer has succumb, and at this point, I am just going to do a fresh re-install. It will be the easier path I think

I thank you for your help,
