DGN2200v3: How Do I Setup a Second Computer to Access the Internet With my Netgear Router?

[eloisjackson25]

Netgear Router N300 Wireless ADSL2 + Modem Router DGN2200v3: I have setup a second computer in my home. It is a Windows 7. I am having a problem with the 2nd computer not accessing the Internet correctly. Whenever I use Windows 7 (second computer), the internet connection causes my Netgear router to be constantly, I mean constantly, reconfigured. The router goes offline and I have to call my ISP provider for a "change of password" to access the internet. My Netgear router always looses connection whenever I use the second computer. QUESTION: How to I configure my Windows 7 (second computer) so that it does not interfere with my primary computer when accessing the Internet? The Windows 7 computer is WiFi capable. PLEASE HELP !!

   Is it connected wirelessly?  How is the first computer connected?
