What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Did you set up a custome SSID name and PW? 

Be sure you forget any prior wifi profiles in the PCs network settings. 

Be sure your using WPA2 and AES wifi security settings on the RBR. Use as web browser to check the RBRs web page.
