Hey,
I have similar problem. Did not find too many patterns, so cannot tell too much helpful details.
The internet had problems on my desktop and laptop too. Sites did not load many times.
After rebooting the router it worked for a while.
Checked firewall settings too. Changed to Interactive mode. Did not help.
In Edge it worked. In Chrome did not. In the end I checked incognito mode, and started to work.
So I knew it was caused by an extension. Tried to disable AdBlock. Works so far both on the laptop and desktop.
