I have Roadrunner and a new(old) Laptop with no Ethernet port...?
Answers:
your laptop probably has a pcmcia port that you can buy a network adapter for. They can run from around 35-45 dollars US depending on the brand and capabilities. If your router is wireless, you can also buy a small USB adapter. If you feel unsure about your options, take your laptop with you to bestbuy, or circuit city, or other retailer and they will be able to tell you exactly what you need. Be sure to take the information about your cable modem and or router with you.
I'm not sure how exactly you'd get a signal unless there is a desktop in your home, but you need a network card to pick up a wireless signal. :) I hope this helps, even if it's just a little. (My roadrunner has a wireless signal, so you might just need a network card.)
