Dynalink DL-WRX36 Askey RT5010W IPQ8072A technical discussion

I'm on r22967 and 5GHz devices in the same br-lan are unreachable locally. It's as if I have the wifi Isolate Clients setting on, but I don't (BTW I don't have any wired devices connected).

Pinging the device by name resolves the ip but results in:
Pinging eeepc.lan [] with 32 bytes of data: Reply from Destination host unreachable.

If I move over to the same br-lan 2.4GHz network, communication to the device is OK,
however... if I switch back to 5GHz, communication is also restored, until I restart the device then the communication ceases until I do the same procedure.

edit... now both 2.4 & 5GHz crashed, no SSID's broadcasting!
