Many folks who use outdoor WiFi access points don't understand that they're not routers, so anything connected to them "looks" to the router like it's connected directly to the router with an Ethernet cable. The result is that network problems like IP address conflicts (two devices with the same IP address) and, sometimes, network loops (a device connected to the network via two interfaces) occur, causing the router to crash. Since it happens with the WiFi access point is added to the system, it's easy to blame the AP, when it's usually the case that someone has chosen to configure cameras with static IP addresses inside the router's DHCP pool, causing the IP address conflict.
Some outdoor WiFi APs can be configured to act as routers, which can introduce different problems and is not generally advised.
The newer "app-enabled" WiFi cameras do not have to have a constant IP address to work, but may not be usable if your Internet connection goes down. If you have a "traditional" IP camera that needs a constant IP address, using DHCP reservations in the router is generally better than using Static IP addresses. However, on Starlink routers, neither is advisable, since they do not allow DHCP reservations OR alteration of the DHCP pool - pass-through mode and an external router is a good idea if you're going to try to do more than use it as a WiFi "hotspot."
A basic understanding of IP networks and network addressing can be very useful, and there are some excellent explanations and "how-to" articles on the web.
