Hey Rapidfalcon,

Thanks for reaching out!

I took a look at the screenshot you provided and it looks like this issue is starting at Hop #2. From what I can tell Hop#2 in the route is outside of your home network which explains why replacing/troubleshooting devices/hardware inside your home did not have any effect on this issue.

I suggest checking out the following article we have on Building A Case to bring to your ISP to try and get this issue resolved:

Along with that, sharing the data shown in your screenshot should help in working with your ISP to get this issue resolved.

If this leaves you with any questions please let me know!

Best of luck,
-TJ
