Camera goes offline and NEVER reconnects all the time

Hi I have a hard wired flood light camera. It is connected to my wifi repeater. This has a good signal. I had to install the repeater because ring kept disconnecting from my router even though my house is so small the distance between the two is no more than 20 meters. The camera goes offline and does not auto connect. I have to turn it on and off. I have a battery operated camera in the shed that is connected to the same network and is much further away. No issues at all with that. Ring help tells me it is network issues. Their support is terrible. Can anyone advise? Thinking of getting rid and finding a better product. I thought having a wired product would be a lot better but it’s terrible. If you go away on holiday and want to rely on your camera to check your property, I worry it is device offline. Waste of time.
