  • PrintPrint
This document pertains to HP and Compaq computers with Windows 7.
Windows 7 supports connection of multiple computers in a home network. Creating a network can be a convenient way to share files and printers in the home. This document provides instructions for setting up a wireless home network and sharing folders and files on the network.

Setting up a local network and file sharing in Windows 7

Creating a network can be a convenient way to share files and printers between computers at home. Use the steps in this section to set up a home network using wireless hardware.
NOTE:To perform some of the steps in this document you must be logged in to Windows 7 using the main administrative account. Normally this is the first account that was created when the computer was first turned on.

Step 1: Before you begin setting up a wireless home network in Windows 7

Confirm that you have the following hardware. Click the heading or the accompanying plus (+) sign to expand the information.
    Not all computers come with wireless LAN hardware. If you are unsure if the computer came with wireless LAN hardware, check the product specifications. In the Questions or keywords field at the top of this page, enter the product number for your computer and type specifications (for example: 300-1025 specifications). Click the link for your product specifications from the list of search results. On the Product Specifications page, check the Networking section for wireless hardware.
    If the specifications do not show wireless hardware but you believe the computer has wireless hardware, check Device Manager by using the following steps:
    1. Click Start , and then type Device Manager in the Search box. Click Device Manager from the list of results.
      Figure 1: Opening Device Manager from the Start menu
      Opening Device Manager from the Start Menu
      The Device Manager window opens.
    2. Double-click Network adapters.
      Figure 2: Network adapters in Device Manager
      Network adapters in Device Manager
    3. Check for wireless LAN hardware.
      NOTE:If no wireless LAN hardware is listed in Device Manager, click Action, and then click Scan for hardware changes. If the hardware is still not listed, restart the computer, and then return to Device Manager. Windows 7 automatically detects hardware and installs drivers upon system startup. If no wireless LAN hardware is listed after restarting, no hardware is installed.If no wireless LAN hardware is installed and you want to connect to a wireless network, purchase and install a PCI (internal) or USB (external) wireless LAN adapter.
    If you need a network hub, consult with a network specialist at a local computer store to find a hub that meets your needs.
Follow these steps before continuing with the other steps in this document:
  • Disconnect from the Internet. If you have a DSL or cable modem, disconnect it.
  • Disable any firewall software. Firewall software might interfere with network setup and can reenabled after network setup is complete.

Step 2: Set up and connect network hardware for a wireless home network

Set up and turn on the power for the wireless network router or other networking device.
Follow the instructions provided by the manufacturer to connect a broadband cable or DSL modem to the router (in some cases, the modem and router are combined into one device, and may be referred to as a wireless access point), and to set up security for the wireless network.
Figure 3: Wireless network example: wireless router, two wireless notebooks, and a wireless computer with a printer
Wireless network
To configure the router, which is the communication center of the home network, connect the router to the modem (if the router and modem are separate), and temporarily connect a network cable from the computer to the wireless router. Follow the specific installation instructions that came with the router. The router and the computer must use the same communication protocols (802.11a, 802.11b, 802.11g, or 802.11n).
NOTE:Some Internet service providers (ISPs) set up the router for you. If the ISP has set up the router, skip this section.
  1. Connect a network cable from a network port on the computer to a port on the wireless router.
  2. Turn on the computer and allow it to connect to the router.
  3. Open a Web browser and type in the router IP address to connect to the router. See the following table for common router IP addresses, user names, and passwords.
    NOTE:The information listed in the table is commonly used by these router manufacturers. If the information is not correct for your router, check with the manufacturer.
    Common Router Settings
    Router Brand NameRouter IP AddressUser NamePassword
    3Com http://192.168.1.1 admin
    D-Link http://192.168.0.1 admin
    Linksys http://192.168.1.1 admin
    Netgear http://192.168.0.1 admin password
  4. If prompted, enter the default router user name and password.
  5. Follow the prompts to configure the router security settings.
    • Name for the router (SSID). This will be the name of the network. Do not use the default name.
    • Type of security. For example, WPA, WPA2, or WEP. It is highly recommended to set up wireless security when configuring the router.
    • Password or passphrase. Never use a blank password.
    • Administrator name and password. This is the name of the user who is allowed to change the router settings. If you want to leave the default user name (admin), be sure to change the password.
Test the network connection while the network cable is still connected. Then disconnect the network cable and proceed with the next step.

Step 3: Running the Windows 7 network setup wizard

  3. Double-click the computer you want to access.
    NOTE:When accessing shared files or directories, the following error message window might display:
    Figure 21: Windows cannot access computer
    Windows cannot access computer error messageThis error can be caused by the following:
    • Password Protection is On and the Guest account is On.
    • The user account does not have permission to access the shared file or folder. This typically occurs when specific permissions are set up on systems with multiple shared folders.
      NOTE:Windows 7 file sharing displays all the shared folders, even those you do not have permission to access.
      To resolve the error, verify the following:
      • The user account has the proper permissions to access the computer.
      • The computer name and user name are spelled correctly.
      • Make sure that Firewall software on any connected computer is set to allow access.
