Hi,
I also had problems with connection in the last week or two. For the last 3-4 days I didn’t disconnect once, so I guess for now its good and it seems it was problem on my ISP side.
Most of the things you can do can be found in link below, try troubleshooting as described to see if something helps.
I did run many WinMTR tests during my problems with connection, that can help because you’ll see if you’re dropping any data packages.
Try to focus on things in this link, I think it will help you, inside post you’ll find link’s to WinMTR and Looking Glass to check your network and the rest of the help tips.
edit: I saw your reply in another post, if you use wifi connection try connecting your PC with ethernet cable
Good luck
