Logging / Deciphering lost connections to remote game server

[asw2012]

I am trying to figure out why I am getting disconnected from an online game.  Ping ranges from 85-100 at any given time.

Internet / streaming / all else works fine.
I disconnected from my main ISP and connected through my phone's hotspot.  All is ok (Eliminating possible server-side issues).

I am new to opnsense, are there any tools I can use to try and track this issue down to decide if it's my ISP or some other factor?

thanks.

Looking at the console, its spamming

arpresolve: can't allocate llinfo for <ip address of my ISP's gateway> on igb0

would this have anything to do with dropping / disconnections?
