how do I use my home Internet service to work on my laptop?

Well have you tried to run your cable from your modem to the laptop?

What you can do is get a wireless router and hook your cable internet into it, and then run a cable from your router to your computer and if your computer senses wireless signals can connect that way.

One thing you can try is running IPCONFIG/RENEW at the command prompt.

Good luck

if you have your wireless with wep you need to install your security code,that way you are able to pick up the signal,call your internet provider for help,that's one of the perks with their service

u might need to install your laptops network driver
