I've got the doorbell hooked up to the mains that's on a switch but it keeps disconnecting from the WiFi it will work for a while then randomly disconnects the WiFi box is right next to it and I've tried all the troubleshooting but it still keeps happening but as soon as I turn it off and back on it connects straight away but then works for a few days/ weeks sometimes then disconnects again been happening for a few months now it worked brilliant for the first 2 weeks I installed it now having this issue any suggestions that aren't the troubleshooting ones as I've tried them multiple times would be appreciated
