When there are many defaults in the setup of Linksys. WPS could also be an easy way for the Linksys RE6700 setup. Just ensure that the existing router also supports the WPS feature. First, press it on the extender and after some time on the existing router. But make sure not much later than 2 minutes. Keep the eyes on the Signal LED which needs to change to be solid blue. The setup can be completed in the same way you have that mode. The WiFi device will automatically find the signals. So enjoy the same network sharing through the same SSID name and password for your host network name. Try to reach the portal through 191.168.10.1. The issue can be associated with the login management page of the extender.
