If your calculated player count reaches around 20 players the amount of bandwidth needed per player will go up and probably take about 7 or 10 KB/s! so you need to turn the player count down a bit. One player takes about 5 KB/s so you take your value and divide it by 5 in my example that is 15.1 players which means our internet supports not more than 15 players. We need this value to calculate how many players your computer can support. We need to convert this value to KB/s (KiloBytes per second) use this calculator: Megabit to Kilobyte It is displayed in Mb/s (Mega bit per second) for example 0.59 Mb/s You need a proper connection to host a game, go to: and test your Upload bandwidth. Stable internet connection (Only if you host the server from your home)
