Have you tried Firefox to see if it's having the same issue? Edge runs on the same back end as Chrome, so it doesn't necessarily rule out an issue with the browser. If it's also doing it with Firefox, then it's likely a networking or ISP issue, but if Firefox works fine, then it's a browser issue.
Once you've narrowed it down, you might also look to see if there are any local fix-it/repair cafes being run in your area? Sometimes it's easier to fix these things hands on.
