Unable to connect to Web via telnet connection

Using laptop Toshiba Satellite A135-S4427 with Vista installed originally. I later had Vista removed & XP installed, and all XP updates are installed. Device Manager shows 2 Network Adapters: 1394 Net Adapter and Intel PRO Wireless 3945ABG. The info on the 1394 Net Adapter is: Realtek RTL8139/810x Family Fast Ethernet NIC. The Properties for 1394 Bus Driver indicates version 5.1.2600.5512. When using Windows Repair function for1394 Connection, I get this msg. "TCP/IP is not enabled for this connection". I have researched other posts for this message and have tried just about every solution offered, but nothing has worked. Attempts to update the driver resulted in msg. indicating the current driver is the best available. I went online to see if an update is available, and on pcpitstop.com found Windows XP 32-bit driver 5.719.0325.2009. Should I download & install this driver to see if it helps? I have worked on this for 2 days and am at my wits end. The reason I need the wired connection is that it must be used by Carbonite to perform a complete online backup of my computer.
