Not sure why, but since the last update, two of my Pan cams will not connect to the internet. When I check the cam log, it stated that wifi strength is between 81%-91%. I have 2 V2 cams and 3 other Pan Cams that are working fine.
Contact Wyze support.
They have software designed to help with connection problems.
You could try removing and adding the cameras from/to your Wyze account.
