I have a MacBook Pro and a wireless network using a DLink DI-624 router and RCN cable internet. This set up has worked fine for years. Tonight I was trying to hook up my new tivo - I tried connecting wirelessly but it wouldn't go through. I figured whatever, I'll call them and set it up later. So then I went to go online and suddenly I can't connect to the internet anymore. I register as being connected to my network, but when I go to web pages nothing will show up and it tells me I'm not connected. In the network control panel it has a green light next to airport and it claims I am connected. When I run the diagnostics test it tells me there is a problem (like I hadn't figured that out). Any ideas??
