I got found another bug in 5Ghz band: after a while, the all 5ghz clients can't access to the internet, but signal strength gauges on them indicates good and full power. Connection to the internet restores after tap on client wifi on\off button, that makes reconnection to RE205. The time period is not determined, sometimes it happen after night of inactivity, sometimes after 2-3 hours. We check internet state at that moment on main router, he's fine.

Remark: I've turned RE205 to access point mode and stands him by cable, until repeating 56-128 channels unavailable in my instance.

Please, make a new firmware release, 5 Ghz band on RE205 V2 still not stable.
