FP300 keeps dropping off Network

My FP300 constantly drops the network. It won’t reset and removing the batteries and restarting it that way does not work. Every time you have to delete it and reinstall it. Its next place it will end up will be the bin. I thought the bulbs were bad but this is worse

Bad experience

Hi @tony9285 what do you use? Thread or zigbee? Which hub?
How far is hub and Fp300 away?
