Door bell cam keeps dropping wifi

I have had the Ring Door Bell 3 Plus installed for 1.5 years and it has worked great until about two months ago when it started periodically dropping Wifi. None of my other cameras or lights have this problem and the Door Bell cam is very close to my router. The problem is remedied by removing the battery and then reinserting it but this has become a real bother and concern as we will be going on vacation and I don't want this to happen when we are gone. I have back up batteries that replace batteries when one needs recharging so it isn't a battery problem. Any advice or is this a problem associated with the 3 Plus?
