Actually this broadband speed ping is quiet unrelated, uless you are using dial up speeds. A ping is the time it takes a packet to be sent from your machine to the server and back again,and i think its used to see if the other machine is still ther but contains no data. and dosnt change even on dial up, but it does start to become an issue when you are shoveling a lot of data about or your machine is working hard or even if the server is working hard, remembering that the server has to send more or less the same data to a number of machines, which is why quiet often the pings may get higher as more people join as the server has to share its time with the other machines as well. Ie you take off, your machine updates its position to the server,the server now tells your machine its got the data, updates your position in the game, then has to tell all the other machines where you are and wait for their responses all the while its tying to ping each machine for what ever reason, now if someone has a bad connection and drops a packet thngs can go really bad as tcpip will try get that data resent or resend the data it lost and all of a sudden pings go through the roof, which is a good reason for staying on servers with pings less than 240 ms especialy when playing shoot them up games. ( by the time you fire your bullet the player has already moved but you wont see it because of the delay and you will miss him ) This works quiet well even on dial as long as the speed is better than 48k or so as really on one machine there isnt a lot of data being sent. If you are using USB then you have another issue in that the pc only talks to each port for a set period of time whether there is something plugged into it or not ( polling ) that is how it knows you plugged your usb stick in. so you have added an extra delay, your pc also has to encode and decode every packet being sent plus correcting errors, keeping track of what packets are being sent and received or lost and need resending while on top of this its driving your game as well, thats a lot of time sharing whcih all affects your ping. There are a few dedicated ethernet cards that actually do all the work for the pc and they can help if you have a really slow machine as it removes some of the overheads. I may be a little wromg and happy to be corrected, but i think im 99 % correct.
