If you mean RoadRunner front end, you are out of luck cuz it a windowz software written in VB6.
If you mean Road Runner high speed cable internet, you should configure a router and use it from there. The hard part is configure your NIC card (wire or wireless) first. Read up at
DSL forum to get help. Most of linux is search, read, search and read, search and read again.

Other option is to contact Time Warner for support, but I don't think you get much out of it.
