Connection drops when working upstairs

Back story: My Xfinity Router/Modem is in my living room. I've been working from home since March, upstairs at my desk which is almost directly above where the router/modem is, give or take a few feet. In all the years I've worked at my desk I never had connectivity issues up here until say early May. I would notice my work laptop reconnecting to the VPN and a couple of times it's just constantly disconnected and reconnected to the internet. I got a new laptop from work...the other one had issues aside from connectivity.

What could be the matter if I still get connection drops upstairs with this new machine? Is my Xfinity router getting old? Something making my signal weaker so not being in the same room as the router causes drops? What are the possibilities here? Do I need a signal booster up here to help keep connected? I'm just looking for options to explore on my end so that I can do my work from home without all the downtime due to connection problems.
