AX1800 NO Internet connection

[bsrrsr]

Spent two hours on the phone with tech-support today. Issue: New Spectrum modem does not connect with new Netgear AX1800. Tech-support basically gave up and blamed it on my two Roku sticks. No Wi-Fi connection on any type of device so it can’t be just the Roku. I’m left without Wi-Fi after 2+ hours on the phone. Help!
