Alright, I have a Linksys to but i am at work and not home so i am winging it from memory. When you enter the setup for your router via a web browser, you should see several tabs that list various things. Click through any tab that sounds like it might have to do with your internet connection or internet in general until you see one with a MAC address in it. Mine has its own tab dedicated to it and I can get more specific when i get home to walk you through it. On that page though there should be a button that says clone my MAC address with a MAC address bar. If that address bar is all 0's, then that is your problem. when you clone your mac address, it should consist of letters and numbers specific to your pc. After you clone it, if there is a check box for saving that info then hit, but on mine it just says save changes and retsart. Once you complete that, it should work fine. I should be home in about 2-3 hours so I will check mine when i get home and walk you through it if we don't figure it out before i leave today.
