Security camera keeps dropping offline

Gobsh

I had two identical security cameras working flawlessly for two years then one day one of the security cameras dropped offline, I tried reconnecting it and it would work for a few days then drop off line again. I eventually swapped the camera for a different brand but the new camera also dropped offline after a few days, I tried resetting my Wi-Fi router, I tried different channels on the router, I tried splitting the frequency and try in the security camera on both frequencies, in each case the camera will drop off after a few days, this is all while my first camera has been working perfectly throughout. I am now on my fourth security camera which works on five megahertz and again it worked perfectly for a few days but as now start to dropping off. I am at a loss as to what can be causing the camera to drop off, it's nearer to the router than the other camera and gets a very good signal, my last resort is going to be to change internet provider, but I can't do that until January. Is there anything obvious that's screaming out that could be causing this other than someone with a Wi-Fi gun deliberately knocking out my camera

probably channel interference from a neighbors wifi.
Download a wifi analyzer app for your phone that monitors the channels and have a look.
