Brand new Orbi Satellite flashes (not pulses) white indefinitely and refuses to connect

Thanks, I had another go at holding the reset button. Held it down for a minute and nothing happened, then turned it off, pushed in the reset button and held it down while turning it on and kept it pressed for about 10 seconds and the power LED changed to red. Still, I couldn't connect over the LAN cable. I tried the same again but held it down for about 30 seconds and the LED started to flash red instead. I kept it held down for a full minute and then let go and I was then able to ping 192.168.1.1 and the flash software worked. I then went through the pairing routing in the Orbi web app and it failed. However, it seems to have actually worked as it is now shown as one of my connected devices so all seems to be good again!! Thanks for sending me in the right direction!
