My macbook pro stopped recognizing my wireless the other day (airport express), although my iPhone and windows based laptop had no issues connecting. I did a software update which included the Airport Utility 6.3.1 update and now cannot even reconfigure the airport express because I consistantly get the message, "and unexpected error has occurred" when trying to join the now unnamed device.
Yesterday I managed to set up the airport again via my iPhone after several failed attempts and finally, after erasing all of my wi-fi network history, my laptop connected. It worked for several hours until the airport was accidentally unplugged and now I cannot connect via computer or iPhone. (Direct ethernet has working internet.)
I've reset the airport again in hopes of adding it anew, but cannot get past the "unexpected error" message on the laptop or iphone. I changed IPv6 to Link-local only as recommended in apple support and there's no change. can anyone lend helpful advice?
