Continuing the discussion from Chaos Calmer 15.05 OpenWRT Firmware:
I did finally get it to work. I had it set to one of the higher channels to avoid possible conflicts with another access point. When I set the channel to the lowest available, I was finally able to initialize it and pick up the 5Ghz radio on my other devices.
However, in both the 2.4 and 5ghz radios, there does seem to be some instability. Several of our laptops seem to have issues losing their connections regularly for 1 or 2 minutes at a time.
