Is there any way to make the signal more strong?

I have 2 cam pro but one of them after one day loses the connection. Is there a way to make strong connection?

I have eufycam 2c cameras with the home base, a camera at each end of the house, had the cameras connected to the homebase /router, but the one camera that was further away from the home base had very poor signal and kept going offline, so I took the homebase off the router and connected it to WiFi, moved the homebase to the middle of the house inbetween the cameras and works now 100 percent
