You can’t (well, unless it is a tech/connection problem they can fix.)
However, cox got pretty amazing recently (at least for me.)
I have the “premiere”, or whatever the premiere is now. But I think that is more the bandwith limit rather than “Ping”? (as the previous poster said.)
While I was 60 to 80 MS, with Cox Internet in Nebraska, now I’m 16 to 20 MS (to Blizzard.)
Just got in game now it is 19 MS 20 MS. Yeah, my connection is “Wired” of course (you always want to use that for gaming.)
I’ve got whatever “insurance” is included as part of it, which is a good thing as part of your plan. This is so that you can get Cox to come back out and “fix” it, if the connection is not good, with no additional charge.
They DO have a data limit now, while they did not used to. it is MORE than generous, though. I’ve never come NEAR the limit, playing Wow/downloading large Xbox games, doing lots of media downloading, etc. The totally unlimited one costs more, but as I said it is not needed for me (if you had an entire family, hitting the net hard, then you might.)
As with my connection, cox did a LOT of upgrading. I’m pretty sure the coax is not upgraded either, in this old apartment building, but the connection is amazingly good now. They either upgraded the backbone a lot, or some fiberoptic line is going directly to Blizzard from where I live.
