A couple weeks ago I started having problems connecting to any wireless network. My network shows up in the list of wifi networks but when I put in my password, it says "Unable to join the network "nw2" Dismiss." I have an Airport Extreme router and I had it set to WPA2 personal. I changed it to WPA ~ no luck. I changed it to WEP and no luck. Now I have set it to no password at all and it STILL says it cannot connect and to dismiss. I have hooked it up to my computer and restored it back to factory settings. There is now nothing on it, not even the games my kids bought. Still, it won't work. What do I do now?
