I have been facing this issue for few days now where the 5GHZ light on my extender is not visible, however the extended 5ghz network shows in available networks and I am able to connect too. I used the speedtest to check the connection speed and its shows the same speed for the 5GHz as it was when the light was on. 

Is there any reason why the 5GHZ is not on even though the extended network is available?
