Periodically cannot connect to the internet w/ 5100

Hello.

So here is the issue. I just built a new computer and have come across an annoying occurrence. If I turn off the computer for a period of time and turn it back on, it doesn't show a connection to the internet even though I was able to be on the internet previously. It shows connection to a network but, not the internet. If I remove the Ethernet cable and place it in my old machine for a few moments while it's on, then re-insert it back into my new machine, it allows me to surf the internet again... the error I receive when letting windows diagnose the problem is that it cannot ping the DNS server (192.168.0.1).

Help anyone?

Lot's of guessing here.

You probably have the 5100b from AT&T.
You probably have the 5100b configured to share the public IP address with the computer (that's the default setting).
You computer is such that when you turn it off, it does not turn completely off. In particular, power is still supplied to the ethernet card.

What has probably happened, is that the IP address has changed while the computer is off. And since the computer is off, it did not make a new DHCP request to update its IP. The modem is no longer honoring the old gateway IP address. When you unplug the cable, the operating system recognized a disconnection, then when you reconnect it recognizes that it could be on a different network and does the whole DHCP thing from the start, refreshing your connection.

You can try setting the modem to "Always attempt to connect". That way, it might retain the old IP.
You can set it to assign a private IP to the computer. That way, the IP assigned to the computer won't change. (I suggest you try both of the above).
