What router are you connected back to? 

Are you using smart connect on your router or how do you have your SSID setup done?

What firmware is on your EX3700?

When you log into the extenders gui (mywifiext.net) it should show you the 5ghz connection back to router. Is this showing as connected?

How do you have fastlane setup?

here's the support page for your device.
