Windows 7 keeps dropping the internet connection

Windows 7 trouble shooter says it is having problems with naming via DNS. Rebooting will sometimes resolve this temporarily, but later the naming gets dropped-----at least that is what Windows 7 thinks. I have noticed that other people can connect to me through Skype, but Windows 7 will not let me connect going out. I was troubleshooting the problem and received a call on Skype. I even told my brother that Windows 7 seems to think that I am not connected.

The fact that I can dual boot into Linux and it has no problems connecting tells me that Windows 7 has a problem. Linux does not have this problem with dropping the connection. I have had the cable company check the lines and modem----and no problems are reported. So the blame points back to Windows 7 every time.

I can connect with XP, Vista, and Linux with no problems like  this one with Windows 7. My problems did not start until I upgraded to Windows 7. So if anyone out there knows why this happens, then please inform me of your results.
