Intenet Access...

You need a direct connection from your computer to your phone line (land line, not cell) for dial-up access. From what I can tell, your Inspiron probably has a modem included, in which case all you will need is a phone cord and maybe a splitter to connect two phone lines to one jack in the wall.
Your wireless PC card isn't going to be much use for dial-up, nor is your V66 (no connection between your laptop and your cell phone).

if you want to use dial up just get a phone chord and a splitter unless you want to switch it manually every time and plug in from there most computers have a setup process if you want to go through that.i too suggest getting a better connection cable or dsl. good luck

will have a modem to use with a dialup connection. Your Dell 1300 Wireless card is built in and can be used if you have either DLS or cable wireless internet access. If you don't have that type of service, don't worry. The card is there if you ever do.

You can find adapters for phone lines almost anywhere. You can get any size from two to five. The adapter plugs into the wall and your phone, computer, fax machine, etc., plugs into it.

Since you gave no clue of what the operating system is on this notebook, I'll assume it's WinXP without SP2:

Download the patch described in the Microsoft article, "MS03-039: A Buffer Overrun in RPCSS Could Allow an Attacker to Run Malicious Programs (Q824146)" (a 1,508Kb file) for the applicable version of WinXP used and keep it on hand and install before ever accessing the Internet for Updates with IE. Should you format and reinstall XP original at a later date, then install it first unless the version used already has been patched through or includes the SP2.
