I was trying to setup a network with my linksys wireless router for my desktop and my notebook. Notebook would be wireless and desktop would be wired. Got everything hooked up and everything worked except the internet, So I decide I'll just do it later and plug my desktop back directly into my modem. Now the internet on my desktop won't work. It says limited or no connectivity. Its receiving information but not sending any off. Any Idea How i can just get my desktop internet back.
