If the above suggestions do not resolve the issue, please export the routing table when the issue occurs.

1. When the issue occurs, launch “Command Prompt”.
2. Enter the following command.
route print > %userprofile%\desktop\routeprint.txt
3. On Desktop, open the file routeprint.txt, upload the contents in your post.
Additionally, when the issue does not occur, enter “ipconfig /all > %userprofile%\desktop\ipconfig.txt” in command prompt. On Desktop, open the file ipconfig.txt, provide these details to us.
