Thank you both (@elaterite and @jgg) very much for the kind words of advice.
I was really struggling with Windows 10 on my desktop. It is an old machine and I found increasingly the simplest tasks like having more than one window open at a time would crash it. The final straw came when I just could not get it to keep WiFi connection for more than a second if it worked at all. I am unable to connect with a cable due to the desktop being on a completely different floor and area of the house. With the fact that Microsoft kept sending me messages that they finishing support for Windows 10 in October and 'encouraging' to buy a new computer I decided to move to Linux Mint XFCE. I have used Linux Mint before over ten years ago and feel comfortable with it.
@jgg @elaterite So far I have not had any problems retaining WiFi connection with Mint XFCE.

If you can't keep WiFi on neither Windows or Linux, then it is a hardware issue.
You may try to move around your CPU. Metal, ceramic and paper can make your WiFi reception 10 times smaller or less.
If that's not the issue, I would buy a new WiFi adapter; a WiFi 7 one costs even less than a mouse nowadays. If your router supports it, you may solve all your connection issues at once, and get a nice performance boost to boot. If not, you can always return it.
In my tests, WiFi 6 can give you downloads at even 500MB/s, if you are in the same room as the router. That means being able to download a movie in 2 seconds.
