@Hearher depending on the cameras thry may not link to the dualband WiFi connection your new hub produces. If you previously had thec2 wifi bands split you may havecto do the following. Go into the My Sky app find the settings for the WiFi Max hub click on Advanced Settings and tgen the badly named Turn off wifi option and switch of the 5GHz signal and exit the page once the hub restarts then try to connect the cameras once connected repeat the ptocess but this time turn the 5GHz back on and the cameras should remain connected.
There are a couple of other possibilities but try that first.
