I made a small mistake by not remembering what I did, and being on the beginning end of computing, I can't remember just how to fix it. I have cable internet which worked fine. I bought a Linksys SRX wireless router and installed it, which I believe changed some IP settings. I then decided to take the router back, and get a different one. Well during this downtime before the next router arrives, my internet no longer works. I get the typical "page cannot be displayed" deal. How could I reset settings so my computer can communicate with the cable modem again? Thanks.
