Silly me, it is limited to two targets! So I am building a case with all that help, but here are some relevant bits I have discovered so far.

Basically the packet loss bursts happen at the same time regardless of whether it's to the COD server I am connected to, the first public IP in the chain or to my own router.

Given that the bursts seem to happen even to my own router is it logical to assume that the problem is inside my apartment and not with my ISP - or is it possible that some sort of interference with my ISP is causing the router issue?

Notes on router.

1: In my old apartment the router worked fine.
2: The ISP has since replaced the router and it did not solve the problem.
