New Modem and Router!!

Greetings, I have had the Doorbell 1 for a couple of years. I just upgraded to the Doorbell 2 as it became a pain to have to charge the battery, leaving the doorbell 'unattended'. I started thinking about around the house security and got a spotlight cam, 2 stick cams, and have ordered the floodlights coming out 4/17. I had a Netgear Combo Modem/Router and when I increased devices, I was having problems with devices randomly not connecting live and blank motion screens. I tried all the suggestions from support to no avail. I then did some research and saw how modem/router combos don't do as well as the separate ones do. Yes, it's more convenient and takes up less space, but the stability is much better buying and using them separately, which is exactly what I did. I went to Target and got a Netgear CM7000 modem, and a Netgear R6350 router and boy does my Ring system work great now! I did configure it for 2.4Ghz ONLY as the system seems to run better on that setting! Anyhow, if your're having trouble and have a combo unit, you might want to try getting one of each!!
