Installing and Using OpenWrt

Hi all.
I have 2 problems with R8000 and LEDE 17.01.0 r3205:

The firs one - With DFS in radio2. Every time i set a DFS channel i get a message: Wireless is disabled or not associated

The second one - If i enable Hide SSID (in any radio) Ssid still appears

Where? From the output of "iw dev wlan2 info" it seems you have it working.

I didn't test it for some time, maybe it stopped working. I have to try it.

If you notice, the radio2 config is completely different :disappointed:
