I have a MacBook Pro Powerbook, and an Airport Extreme system on Homechoice Broardband - been working fine for ages. I seem to have lost my airport connection. I've reset my Airport basestation a few times. My airport indicator in the menu bar says there is signal. During one of my resets I tried the PPPoE setting ( rather then the DHCP one ) and since then the Airport admin can't find my basestation. - Is there a way to zero everything - computer and basestation - and start over. I find this pretty confusing to say the least!!! I can still use it fine on my girlfriends iBook - so reckon is on my end where the problem lies.... Any ideas??
