Can I extend Extreme (A1354) network with Express (A1084)?
I have a WIFI network consisting of an Extreme (A1354) (attached via cable to network modem, etc.) and two Expresses (A1084).
Prior to Mountain Lion, it worked as well as can be expected. Devices (iMac, iPhones, MacBook Pro, iPads, etc.) would generally attach(?) to the closest device, with only the iMAc attaching to the Extreme at 5GHz (others at 2.4). The two Expresses allowed me to extend the network across our house and devices woudl attach if near them.
After some upgrade (Mountain Lion?? - not sure exactly when) devices quit attaching to the two Expresses. They seem to work just fine and show up on network scanner programs, etc. as though they are still part of the network. However, other devices will not attach to them. The lights are green; I have installed Airport Utility 5.6 and it shows them to be just fine (except nothing attached). I have hardware reset them and re-added them to no avail - nothing attaches. (I have not tried WDS, as I used that in the past and found it to be of no benefit.)
Is there something I am missing?
Why did devices stop attaching to the two Expresses?
