Hi Hector - I am not exactly sure of your understanding of the Ping Assist.
If you have bad internet, the ping assist will allow you to connect to hosts OUTSIDE of your Geo-Filter, as long as they are inline with your setting. So if you have a Geo Radius around Panama City, with STRICT mode enabled, you will connect to hosts there (assuming there are hosts available, which I don't know with BO3).
But if you have a Ping assist of 40ms, you will most likely get hosts in and around Panama City (as available), but you will ALSO connect to any host outside of your radius that is LESS THAN the 40ms ping that you said was acceptable.
If you are looking at this feature to connect to just lobbies around you, with an occasional game outside the Geo-Filter provided the ping is beneficial, I think this will work for most supported games (NOTE: Black Ops 3 is causing match making issues for everyone currently and you may NOT have a dedicated server in Panama City - I honestly don't know). However it won't make your internet connection itself any more powerful.
Does that make sense?
