Tidbyt can’t detect Netgear R7800 wifi network

Just got my Tidbyt, and I can’t complete my installation because my wifi network doesn’t show up on the Tidbyt wifi network list.

My router is a Netgear R7800. As far as I know, DMZ is not set-up.

Please advise.

I updated the router’s firmware and exposed the 2.4Ghz band, which seems to have done the trick. Not sure Tidbyt works with 5Ghz.
