Brand new dell 2in1 won't connect to wifi

[Windows Central Question]

Called Dell, no help, called best buy twice and they can't do anything unless I bring it in and I live 2 hours away. Please Help!

 

[RumoredNow]

Power off your WiFi router. Unplug the power cord and the LAN line in. Wait 5 minutes. Plug the router back in to LAN and power and turn it on.

Try again.

If that fails try a LAN Line between the Router and the Dell. Try to log onto the router and inspect settings.
