Hi. Earlier today my airport stopped working. I have a 24-inch iMac. On our PC desktop the internet is connected with ethernet and is currently working fine. It also works on my brother's Wii which is connected through Wi-Fi. I can connect to the wireless router on my computer and I can get to it's settings but for some reason the internet won't work. I've tried power cycling the router a few times but I don't think that's the problem because the Wii browser works fine. I also tried deleting the password from the keychain and reinputting it when connecting to the router. Any Ideas?
