Connect to Arlo doorbell camera

before giving up, something to try. Setup a phone hotspot with the exact same ssid/password as the orbi. Shut off the orbi. Then go through setup on the arlo with it connecting to the phones hotspot (with the exact same ssid/password as router). See if its sets up. If it does, let the camera go through updates and go online. ONce that's done, shut off the hotspot and turn the orbi back on. See if it connects. When arlo first started connecting to mesh setups, I had to do that a time or two but I haven't had to do that in almost a decade. Worth a shot through
