Looks like my wireless router has died.
I currently have my network cable plugged directly into the cable modem. With it plugged into the router, the computer just sits there trying to connect to the network and then the connection icon goes to the yellow triangle (Windows 7). No Internet or anything. I've already tried rebooting the computer, unplugging the router, plugging the network cable into different ports on the router, the whole works. I've been having intermittent problems like this for a while now, but usually they are resolved by doing the above, but not this time. Guess I'm just going to have to buy a new one now. >:(
