i’m having the same issues!
I moved you to a new thread so we can focus on troubleshooting with you individually. Could you provide the WinMTR test? Run the test until the problem occurs for 10 to 15 minutes. Copy and paste the text file created and paste it between two ~~~ like so:

WinMTR Here
~~~
If you have issues pasting here, use Pastebin and post the end of the link. (ie. 123456 for pastebin.com/123456)
what do i need to write in the host box?
On the support web page linked in Caterpepi’s post, there is a menu “Select your game”. After you select “Diablo III”, a list of IP addresses will show up. Choose the correct IP for the realm you are playing, and enter it into WinMTR.
