My modem connection is craptastic, and I keep getting connection interrupted. What should I do?
Upgrade to broadband, next question. But seriously, you can get a playable connection using a modem is you do some basic stuff. It may not always work, but often it will. First, set your rate to 3500 to 4000 max. Do this by entering /rate 3500 in the console, or putting seta rate 3500 in your config file. Next, you may need to cap your fps. Some people cap it as low as 25, but that will get you booted from PB servers if the administrator is using the recommended PB cvar settings, so cap it to 43. Do that by typing /com_maxfps 43, or entering seta com_maxfps 43 in your config. 43 has a double benefit. Not only may it help your connection, but it is also one of the magic numbers that allows you to jump higher due to the way the game engine handles physics, providing of course that your system can maintain 43 fps. Do that by typing /com_maxfps 43 in the console.
