I recently downloaded a new airport express update (it prob became available 2 months ago) I am now not able to access my airport extreme base. There is an amber light flashing on the base, which I know means there is a problem. I have tried resetting it and gone into Utilities to do a manual set up, but it is not recognizing any airport device. It will only rescan and rescan looking for one. I am not sure how this download affected my wireless, but none of the other computers in the house are recognizing the base. Any suggestions? Thanks!
