4 cams keep dropping

I have 2outdoor stick cams and 2 light (not flood light) outdoor cams all 4 just drop wifi and will not reconnect unless I go and reset them. I have gotten my ISP to put in new modem (on my 3rd now) I have use access points that sit 6 inches from the cams they will connect work for a few days then bang all 4 out again. I thought maybe the power plug (each set is on its own plug wit nothing else plugged in to there Cricut.) Switch 3d to different power outlets no difference. I have completely removed them reset them put them back up and again after a few days out they go. I bought them all at the same time from ring.com. no the rest of my ring stuff all work fine.i have path light and bridge, 12 window/door sensors, 2 motion detector, 2 gen 1 key pads, 1 base, 5 smoke listeners 2 doorbell cams, 2 indoor stick cams all work perfectly. Any help please
