How to Install the NETGEAR AC750 WiFi Range Extender
Install the NETGEAR AC750 EX3700 near the router, complete its documented setup, then move it toward the weak-coverage area while preserving the router link.
Install near the router first
Plug the extender into a nearby outlet for initial installation. Wait for it to start, then use WPS if supported or follow the NETGEAR genie browser setup in the instructions.
Join the router network
Select the WiFi network you want to extend and enter its password when prompted. If the router uses separate network names, choose the band and name intended for the extender.
Check the connection indicators
Complete the remaining setup prompts and confirm that the extender indicates a router connection. If it does not connect, check the password and follow manual troubleshooting steps.
Relocate it between the router and dead zone
Unplug the connected extender and move it toward the weak-signal room while maintaining a reliable link to the router. Use the EX3700 indicators and manual to judge placement.
