Ethernet has internet but wifi has no internet access (you can connect to the wifi)

Firmware is all up to date, I had a router completely brick on me last night and went to Best Buy and got the Nighthawk AX8, everything is configured correctly with my Fiber ISP and all the PCs on the network that are wired in have internet and no problems. However anything connected to the WiFi has no internet access. The wifi is on as you can connect to each of the three bands, Just no internet is available for either smart devices or laptops.
