Connecting Google/Nest Cameras to New Wifi Mesh

Hi everyone, I recently upgraded my home wifi system to a TP-Deco BE11000 mesh network after experiencing issues with my previous Google mesh setup. While the new system is performing well, I’ve encountered a problem with my Google and Nest cameras. Despite keeping the same SSID and password, the cameras are showing as offline in both the Google Home and Nest apps. They are greyed out, and I can’t seem to get them to reconnect. A few of the cameras are mounted high up, making it difficult to access the QR code or the six-digit setup code. I’ve tried powering them down and restarting, but that hasn’t helped either. I’m wondering if there’s a specific step I’m missing to ensure seamless connectivity, especially since the network credentials haven’t changed. Has anyone else experienced this issue, and if so, how did you resolve it? Any advice would be greatly appreciated!
