My home network consists of DSL Router/WiFi base station combo upstairs and a develo power-line wifi bridge/base station downstairs (it's not a big house- just thick walls).
Connecting to all of this is an iMac, MacBook Air, MacBook Pro, iPad, 2 iPhones, Apple TV and an Epson wireless printer. The iMac, printer and Apple TV, MBP and 1 iPhone all see both base stations just fine. The MBA, iPad and the other iPhone cannot see the DSL Router/WiFi, even within the same room. This is a new problem that has only developed over the last few weeks.
I've done the most basic of this, restarted everything, but don't really know what else to try. Any thoughts?
