If you live in a place with a heavy population, then there is the possibility that your WiFi signals could be getting interference, which would hamper your work as the WiFi signals keep on decreasing.

This can avoid incompatibility of the device and may help in Linksys RE6400 Setup. Always follow the manual of the device.
