To connect a Windows XP Home PC that is already on a LAN to the wider Internet, use the router/modem that provides Internet access to the network and configure the XP machine to use it.
- Make sure the physical connection is in place
- If using Ethernet: Plug an Ethernet cable from the XP PC’s network port into a LAN port on the router or into a wall Ethernet jack that is wired back to the router.
- Verify the link lights are on (on the PC’s NIC and on the router/switch).
- Confirm the network adapter is installed and working
- Click Start.
- Right-click My Computer, then click Properties.
- Click the Hardware tab, then click Device Manager.
- Expand Network adapters and confirm a network adapter is listed without warning icons. If it is missing or has an error, install the correct driver from the adapter or PC manufacturer.
- Ensure the router/modem is connected to the Internet
If the router is not yet set up for Internet access:
- Connect the modem to power and to the wall jack (phone/cable/fiber) as instructed by the ISP.
- Connect the modem’s Ethernet port to the router’s WAN port.
- Connect the router’s LAN port to the LAN (switch or directly to the PC if needed).
- Power on the modem, then the router.
- Run the Internet connection setup wizard on Windows XP (if needed)
- Click Start.
- Click Control Panel.
- Click Network and Internet Connections.
- Click Set up or change your Internet connection.
- Click Setup.
- Follow the New Connection Wizard to configure the PC to obtain an IP address automatically from the router (typical home setup). The router will handle the actual ISP login/connection.
- Verify Internet access
- Open a browser and try to visit a website.
- If it fails, check that the LAN connection shows as “Connected” in Network Connections and that the router has Internet access.
If the building is already wired for Ethernet, the XP PC can be plugged directly into an Ethernet wall jack that is connected to the router which has Internet access.
