On my cell, so bear with me. 
 

Just got the Deco BE63 system and it's working like a dream. Also just got my Reolink video doorbell camera, and I set it up with my old router shortly before setting up the Deco BE63 mesh system. 
 

It was working fine with my older TP link router, but now it absolutely refuses to connect to the BE63 via WiFi. I'm connected via LAN cable to get it set up, which I did with the old router and it worked just fine. Any advice?

I've tried:

- limiting to just the 2.4 hz and 5hz networks, separately and individually;

- changing the security from all available configs of WPA/WPA2, as well as others. 
- turning off the 6ghz network:

im not that tech oriented but this is driving me up a wall. No idea why this damn doorbell used to work with my old garbage router but won't work with the newer tech.
