Netgear EX3700 connection drop, Constantly

Hi,

I have a Netgear EX3700 Wifi extender, Great piece of equipment however I constantly have an issue where I will lose connection for a brief moment. They are more than common to be a small issue and it's got to the point where I'll most likely be looking at other wifi extenders. The signal I have is 80% from my router and I've followed most if not all guides on how to fix this. I've updated the firmware before anyone asks because that seems to be everyones answer.

I have also tried 

1. -restarting the router
2. -restarting the reciever
3. -resetting the router
4. -resetting the reciever
5. - disconnecting android devices to isolate error
6. - disconnecting windows devices to isolate the error
7. - different wifi channels ( see above)
8. - fastlane technology (used all available options, no difference)
9. - different networks
10. - attempted 2.4 and 5ghz networks with different channels, made no difference.

I am more than welcome to sugestions on how else I can fix this as I would prefer to resolve the issue with this extender. 

Thanks
