I'm having a very strange problem with my Afoundry EW1200.
The 2.4 Ghz Network seems to work under LEDE LUCI, but nothing show up on phone or Wifi Inspecctor.
My 5Ghz Wifi is working ...
I've open a case here before, but the driver was missing ... Here
I've never checked if it was "really" working, because i've many other router over the house ...
(If you check the screenshot, there is no information about speed)
If someone have an idea ...
If you need more informations, ask !
That iw dev looks good on 2.4 GHz suggests to me that it is up. It might be that your client prefers 5 GHz. Maybe try changing the SSID for one or the other and you may be able to "see" both.
Auto-select for channels is pretty useless as it just picks a channel without scanning. If you're in a busy area, picking a good one yourself and setting it in config may be helpful for performance of your links.
I didn't see it earlier, but I don't see output power on phy#0, so either it got cut off, or its not up (or both).

Your hostapd-phy1.conf looks similar to one that I have running from interface= onward. A couple of differences I see include:
