Airport utility connection

Okay, so I have the Airport Extreme and have been using it to connect to a network w/ my MacBook Pro for over 4 years now and last night I messed things up. My internet was running slowly so I started fiddling w/ the Airport settings and somehow I disconnected from my network & now can no longer find/use it. My network was called Apple Network be90b2 and when I try and view available networks to connect to, it wont show up. Basically it's as if it no lonfer exists.

Don't know if this exactly makes sense but if what I'm saying does, please help.

Airport Disk Utility > manual setting > Summary > At the bottom of the box in profiles try recovered settings.

will that work even when my airport utility only scans&re scans for networks? Now whenever I open the application, intstead of loading to it's normal information, all that shows up is a "unable to find network" type of message response. & when i go to the top of the screen and click on airport prefrences etc...everything is in gray. not even able to to a manuel setup or anything else like that

You might have to re-set the AEBS by using a small paper clip in the hole in the back the
instruction are in the booklet and if you don't have that then they are available at Apple's
website as a PDF manual that you need to keep. You might find the assist me works ok.
