Hello, after updating out e500 and e700 to firmware 188.8.131.52-r3 I have many trouble to with 5 ghz radio. It is often disabled. The state (CN-Maestro => AP => Details) is mostly “disabled”. Sometime “INIT” or “DFS”.
It seems, that I have to restart the AP`s to enable the 5Ghz Radio.
Before the firmware Update the most AP`s had firmware versions 3.xxxx I dont remember problems with the 5GHZ Radio before.
My location is in Germany at the baltic sea.
