iZone entities unavailable

Since changing my router from Google Wi-Fi to a Netgear Nighthawk MR60 router my iZone entities are no longer available. The network itself is okay, the izone app on my phone connects to the izone controller. The rest of the integrations are working within HA (HAOS 6.2, core-2021.7.4 on a raspberry Pi 4). I’ve deleted and discovered the izone repeatedly but still the entities are unavailable.
Would appreciate any advice!
