EX7700 has stopped connecting to 5GHZ network

Hi, I've had an XR500 router and ex7700 extender for about a year now. And for the last month the extender won't connect to the 5ghz network. I've tried switching channels and at it connected but after a day or so switches back to 2.4 network. I'm in the UK and my wifi is full fibre 200mbps which regularly tests at 218 through my router. The extender hasn't been moved. Has anyone any ideas why this has just stopped working?

    1. what firmware is on the xr500?

    2. what firmware is on the EX7700?

    3. what channel are you using for the backhaul for the EX7700?

    4. Have you tried changing the backhaul channel (you'd have to change it on the router)

      The xr500 is on the version ending 114. I'm signed in to the Extender and I can't see the version but when I searched for update it said the latest was installed. I don't what a backhaul channel is.

        There's a .120 firmware for the xr500 you could try. 

        New Firmware v2.3.2.120 (XR500) - NETGEAR Communities

        The backhaul is the connection between the XR500 and the EX7700. 

        the EX7700 uses a dedicated backhaul. So if somethings interfering with the XR500's 5ghz, it'll affect the EX7700's. 

        thats why I'd try changing the backhaul channel
