We had trouble running a Zoom session at the other end of our house from our router. The video and audio failed constantly. Clearly a bandwidth issue; it was unusable. So we tried a WIFI extender. I purchased a “renewed” version of the Netgear AC1200 from Amazon. It was simple to install; the directions were clear, and I was up and running in 20 minutes. It’s not as easy as falling off a log and I would not ask a complete networking newbie to install it, but it’s pretty easy. As expected, it halves the download performance, so in my case, a 200 Mbps link turned into a 100 Mbps link, which I tested with Zoom and Google Hangouts. It was plenty fast with no performance issues at all.
