Hey Nimblenanner,
If you have the Killer network drivers, you may want to try the steps here.
Otherwise, we would want to get a MTR test so we can see what’s happening on the route. To do this, download WinMTR and type 24.105.62.129 in the “Host” field. Click start, then play for about 20 minutes, then click on “Copy text to clipboard” and paste the results here. Highlight everything you just pasted, and hit the “code” button (</>). That’ll make the information much more readable.
