wifi connected, no internet connection

[tslapnicka]

Bought a nighthawk router ( model RAX10) and have wifi connectivity but not internet. Have done a reinstall , a power up but no change. I have Spectrum as my ISP but have not contacted them directly.

What is my best way to get the router functioning.

What modem/gateway do you have? 

Try this: 

power off the modem and the router. disconnect all cables from both (even coax from modem).  Wait 2 minutes. 

then connect coax back to modem and power it on. give it a couple minutes to fully boot. 

Then connect lan cable from modem to wan port on router. 

power the router on. Wait a few minutes for it to fully boot. 

Then try setup.
