It's probably a protocol inconsistency...I would check the settings on a known good system...and compare those one-by-one to the system having problems.

I would also remove the power cord from the router and the modem...for five seconds or so and the put each back in. Force the entire network system to recycle.

use some anti-spyware/something of the sort. I had a problem a few months back where I couldn't get any web pages to show up, but i could ping web pages through the Command prompt..

Try ad-aware, and scan your computer with it.

Although, first you might want to try and turn radio on, if you're using a wireless connection.

Also, you could reset the router to factory installation, but you might not want to try that unless you have to. (Removes everything, like passwords, ect, ect....)

gutwosa,

In case it's still not working, to me, it looks like the DNS connection is being blocked somewhere.
If you reboot the computer, is the address resolution working? And then after some time things fail?

If yes, I'd check the following:
1. In the router should be some setting similar to "Keep Alive" always. If it's a DSL connection, they do tend to disconnect when inactive.
2. In the firewall, the DNS servers should be not blocked by default, but included in the list of safe/trusted/allowed addresses
3. In the TCP/IP properties of the Network connection, DNS should be obtained automatically from the router OR listed explicitly.
