Losing connecton and not recording

I have a battery powered stick up camera pointing out of my window and it worked perfectly for a few months then suddenly without any warning lost connection to wifi despite being within a couple of meters from the router on fibre. I had issues resetting it but finally worked, it tried doing an update and after quite a while started recording me however the next time I check a few days on it's happened again, I do the same thing and again it goes onto an update and yesterday the same yet again. Every time it tries an update so wondering if the update is bad and causing the issue or if the camera is just beyond use despite being fairly new and charged. My outdoor camera is working perfectly and never lost connection and is twice the distance from my router. Also annoyingly it makes me reset all of the settings every time so highly annoyimng on all counts. Any ideas as I cannot seem to get through to the UK or US call centres online or by phone despite being within their hours.
