AC1200 Dual Band WiFi Range Extender(EX6120) Device Lights turns amber/red every now and then

plemansHere are the details

Serial # is 4D6C0875A0BED, I have updated firmware 1.0.0.58

Its connected to Nokia Wireless Router given by my ISP and the plan I am on is 100+ Mbps plan & other devices/Extender get at lest 40+ Mbps speeds

Distance between main router and Extender is around 30 Feet. (max) No walls no interference just straight sight/air between two devices.

The Distance from Extended and laptop/workstation is 8 Feet line of sight straight and there is one wooden door of 2 inches thickness (door is closed as its my study room/office)

I used both 2.4 & 5 GHz both drop off device connections regualrly however 2.4 is more sensitive YES.

Hope this helps
