If a device is "approved", but then it reconnects to the network with a new IP (but same MAC) address, will WiFi Guard still know that the device is approved?

WiFi Guard identifies devices by MAC addresses. So if you mark a device as "known", it should retain its status even if it later uses a different IP address.

WiFi Guard displays IP addresses to help users to distinguish devices, but, depending on your device and network settings, IPs may change quite frequently. Some devices can even have multiple IP address at the same time - WiFi Guard still recognises them.
