Hello! My name is*****I am a certified computer professional who will assist you.
If there is a problem with connecting your devices to the extender wireless network, please un-plug both the router and extender power adapters from an electrical outlet and leave them unplugged for 1 minute. After that, re-plug them and test connecting to both wireless networks.
Let me know if that helped.
