Stickup camera/doorbell all pixelated and jerky

I have had a battery doorbell camera/hard wired for about a month. A week ago I added 2 more cameras. I bought a Chime pro and now the doorbell and one camera have good reception. One still has poor strength. The video was excellent on all three cameras until today when I had to reset my router for a lost connection. Now all 3 videos are poor quality, pixelated, sticking. When I did my set-up I did all 3 right next to my router, then took them outside and put them up. I'm assuming this has something to do with my router. I get 110 to 120 Mbps down and 5-6 up. I'm not sure what happened here. I rebooted my router a couple more times with no change. Where do you think my problem is? Thanks to anyone who has an idea.
