Hi, I recently had to reinstall OS X due to a crash. After the re install i was unable to get my wireless internet to work. It worked 100% before i had the crash, all other pc's still work wirelessly. Here is a little rundown of my situation. 1. I can connect to my network with a full strength singnal. 2. I can't connect to the internet through the network. 3. I had it working before i had to reinstall my os 4. My dads powerbook, my windows pc, my ipod touch, all work wirelessly still through the network. I tried to copy setting from the powerbook but it has tiger and im running leopard it does not have the same options. I connect using PPPOE but when using the assistant it will either, 1. keep telling me to reboot the modem (nothing found) or 2. cant find pppoe host (Im with sympatico - canada DSL) I really need help, a wired connection works but its a pain. My pc info: os x : 10.5.7 2ghz intel core 2 duo 2.5 gb memory If anyone could help i would apreciate it, I got no help from apple discussion boards.
