MacBook pro not finding my network ?

Having issues again,.....

1 apple tv and both MacBooks are unable to find my network.

My extreme is 10 feet away.... My apple tv in the bedroom finds it fine. My iMac in the bedroom as well finds it.
All 3 iPhone are running fine as well as the iPad that sits in the living room as well...

What gives... ?

I went into airport utility and my MacBook pro can't find any airport devices.

Frustrated !

Any thoughts on what to be looking at or what tests I can run to isolate the issue?


Thanks

I've encountered this with a non apple router. The problem was interference from neighbor's networks. The solution was to change the wireless network channel in the router settings.

How do you do that ?..

I'd love to find a solution !
