Older airport express with newer airport extreme
I have had an airport express, A1084, set up on my network for an old laser printer for about 8 years. It has worked flawlessly.
I am currently running Mavericks on my desktop and just updated from a 2nd gen airport extreme to a 5th gen extreme and now I cannot get the A1084 to connect.
I have a MacBook Pro using Snow Leopard and I tried to connect with that but the express never showed up even when plugged in using the ethernet cable. It worked just fine until I upgraded the airport extreme. Any suggestions?
