Looking for how to resolve high ping despite being similar distance than my opponent

[slim bone]

I play with a friend 2 mins away from me, and yet his ping to the Newark server is on average 15-20, while mine is double that. Is there anything I need to do with my network to fix it? Reddit, Steamboards and other places have very lousy advice like "get better internet" or "Idk it should be fine" but the reason this is an issue is because I would get really bad lag spikes (delay 10+ and roll back 10+) which make the game unplayable

Any real advice or direction towards players who suffer similar issues with the Newark, Ashburn and Toronto servers would be great.

I have a friend who also lives close and his ping tends to be better at further areas so probably just test around different servers till one works better

Weird

Did he also have those large lag spikes
