I don't see anything wrong with those traces. Maybe we're overlooking some basic steps, have you tried reinstalling the game on both?
Can you link me the specs or actual product link of the modem in a private message?

Game got downloaded recently. shouldn't be an issue.
This is my old modem.

I just got it installed. I did a few small matches, and I think it's less laggy. I haven't had a chance to do a full lobby yet with both consoles. But this may have helped the issue.
I'll be doing more tests.
