Need NTL config files in LA

[Flying Karapet]

Hi All,
Can anyone supply me an up-to date list of ntl modem config files
Sorted - Thanks to all members

My isp is Time Warner Cable or Roadrunner I live in United States LA

I have my Modem setup with Haxorware. I found the menu where I can upload config files to the modem but I have no idea where to get these config files.

I want to go faster since my speeds are now at 2mb down and 0.2mb up.
One last thing I don't understand what a config file is suppose to be most places online just talk about their names of the file.
This makes me wonder is the files just the name and nothing else or dose it actually contain more data in the file.

If any one can give me config files email them to this email rshtunik@yahoo.com
