Windows 7 Wireless Networking Usage and Troubleshooting Guide for the Home



For help with setting up, connecting, sharing files, photos, music and troubleshooting your wireless network refer to the expanding section and follow the steps and refer to the links.


For the purpose of this document, Wireless is defined as the means to move information from one computer, Person Digital Assistant (PDA) or SmartPhone to another by using radio waves instead of wires.

The radio wave is modulated similar to Television and FM signals to carry information along with the wave.

For computer, PDA or SmartPhone communication the distances will generally be short (less than 200 feet or 60 meters).

For Mobile Broadband adapters (cellular) the distance will depend on the terrain and the number of cellular towers nearby.

There are many different types of wireless devices you use every day without giving it a second thought. Cell phones, cordless phones and remote controls for your TV are just a few everyday devices that use wireless technology. Wireless technology for computers, can be just as easy and carefree to use when setup correctly. For the rest of the document when referring to Wireless it's talking about wireless technology for computers.

Wireless technology for computers is divided into different types. Each type of wireless technology is covered in a different section. Each technology has its own uses, processes and standards. Below is a list of the different technologies with a brief explanation that will be covered.

  • Wireless Local Area Networking - Referred to as WLAN or Wi-Fi. This type of wireless is used to get to the Internet and connect other devices such as computers, PDAs, SmartPhone and printers just to name a few.

  • Bluetooth®- Bluetooth technology is a short range wireless technology for connecting devices that are very close (30 feet or 10 meters). This technology is used to connect devices such as Bluetooth keyboards, mice, stereo headsets, PDA's and SmartPhone's. Many people already use this technology to connect wireless headset to cell phones.

  • Mobile Broadband - Also called Wireless Wide Area Networking (WWAN). Mobile Broadband uses cellular service to provide access to the Internet. Mobile Broadband technology is used in cell phones that can connect to the Internet. It requires a data enabled cellular service which is not available in all areas.

  • Wireless USB - This technology recently became available. It allows a wireless connection from a computer to a Wireless USB hub. USB devices are then connected to the Wireless USB hub and the hub acts as a bridge. The range is very short (10 feet / 3 meters).

In order to connect to the Internet wirelessly certain hardware and services are needed which are listed below. Without any one of these items connection to the internet is not possible. The range from the router typically will be limited (less than 200 feet or 60 meters).

  • Wireless Network Adapter - This is a device that can be installed inside the computer or into a USB port. If you do not know if you have a wireless card installed contact the manufacture of the computer to find out.

  • Wireless Broadband Router - The router is used to connect all of your computers to a network, and to the Internet.

  • Broadband Internet Service Provider (ISP) - Telephone (DSL) and Cable TV companies usually offer Internet service.

Note: When setting up your wireless network try to locate the wireless router somewhere close to the middle of the house or office, when possible. At least place the wireless router as high as possible to bypass interference.
  1. Your Broadband Internet Service Provider (ISP) will either come to your residence or business and set up the Broadband Modem or send you a do-it yourself kit.
    Note: When using the do-it yourself kit, follow the instructions provided for setting up the Broadband Modem or contact your ISP. Most likely you will need to contact your ISP anyway to set up a user name and password (when using DSL), or register your Broadband Modem (when using cable).

  2. Once the Broadband Modem is set up and working remove the network or USB cable that is connecting the computer to the Modem.

  3. Turn off the Broadband Modem for at least three or more minutes (this is necessary to make the Broadband Modem find the wireless router later).

  4. After the three or more minutes is up, attach the wireless router with the supplied network cable and turn the Broadband Modem back on.

  5. Refer to the documentation that comes with your wireless router for installation instructions.
    Note: For more information on setting up you wireless router refer to the manufacture's website (Table 1).

A Wi-Fi network name (SSID) is the name that your wireless router broadcast (like a radio station) that allows you to identify your wireless router from your neighbors.

The SSID that your wireless router has when you take it out of the box needs to be changed during the initial set up using the CD that came with the wireless router, it needs to be between 1 to 32 characters long. It is case sensitive, which means when you decide on the SSID you will have to put it in each computer exactly as it was put in the router.

It should not include your address, name or anything else that will identify who you are.

A Wi-Fi security (network) key is very similar to a door key, it protects yourself from unknown people getting on your wireless network.

Below is a list of the three types of wireless security offered for home and small business users as well as their strength in relation to the others.

It is recommended that the wireless network be configured with the highest level of security that the wireless devices have in common.

  • Wired Equivalent Privacy (WEP)
    Low protection

    WEP is one of the original security types. Every home wireless router supports WEP even the latest models to make it compatible with every wireless network adapter. While WEP is better than no security the network key used to encrypt the wireless data can be broken in as little as a few minutes.

  • Wi-Fi Protected Access (WPA)
    Medium protection

    WPA was developed to close the security holes that WEP has. It uses several mechanisms to prevent the network key from being broken but still uses the same encryption method as WEP.

  • Wi-Fi Protected Access 2 (WPA2)
    Highest protection

    WPA2 has been implemented has the highest form of security for home and small businesses. It takes the mechanisms used by WPA and uses a more secure encryption method.

WPA and WPA2

WPA and WPA2 uses letters (a-z, A-Z, 0-9) that are between 8 and 63 characters long. The key can be made up from any upper and lower case letters, numbers and the special characters (~!@#$%^&*()_+:;'"<>).

It is recommended that all three types of characters be used in the key and that they are used in a random order. This will make it very difficult for someone to guess the key.

WEP

WEP comes in two lengths 64bit and 128bit and in two forms ASCII and Hexadecimal. The key you create will include an additional 24bit header so the key you create is actually only 40bits or 104bits long. That's why a 64bit WEP key is also referred to as 40bit. ASCII are the numbers and letters we use every day, a - z, A - Z and the numbers 0 - 9. Hexadecimal is also known as machine code, when a computer is running a program it's being told what to do by Hexadecimal numbers. Hexadecimal uses the numbers 0 - 9 and the letters a - f.

Refer to (Table 1) for the number and type of characters needed to create a WEP key.

Key Length ASCII Hexadecimal
64bit 5 case sensitive characters
(a-z, A-Z, 0-9)
10 characters (0-9, a-f)
128bit 13 case sensitive characters
(a-z, A-Z, 0-9)
26 characters (0-9, a-f)
Table 1: WEP Key Creation

(There are free WEP and WPA key generators available on the Internet.)
Note: Once the security key is created, be sure to write it down and put it in a safe place.

The easiest way to find your wireless network name (SSID) is to put the computer and the wireless router side-by-side (3-9 feet (1-3 meters) away from each other).

Do one of the following tasks, and then follow the instructions below:

  • For a notebook computer, move the computer next to the wireless router and follow the instructions below.
  • For a desktop that is not already connected it may be necessary to move the wireless router close to the desktop (you do not need to move or power off the broadband modem because Internet access is not needed at this time, but any other computer(s) that is connected to the wireless router will not able to access the Internet during this process). Make sure the wireless router is powered on after moving it and follow the instructions below.
    • After finding your wireless network name, you will need to move the wireless router back to its original location and re-connect it to the Broadband Modem.
  • When you have a computer that is connected to the wireless router with a network cable, it is possible to get the wireless network name directly from the wireless router, refer to the Getting the Wireless Network Name Directly from the Wireless Router tab.

  1. Locate the network icon either in the taskbar or in the hidden icons area (Figure 1).
    Note: Both are located in the lower right-hand corner of the screen.
    Windows 7 Hidden Icons Arrow
    Figure 1: Hidden Icon Location
  2. Look for a listing that has the most green bars next to it (it may be necessary to scroll up or down to find it).
    Note: When there is more than one listing with the same number of white bars or the listing reads as "Hidden network or Other Network", refer to the Getting the Wireless Network Name Directly from the Wireless Router tab.

  3. Write down the wireless network name with the strongest signal, exactly as you see it.

Note: 2Wire wireless routers provided by AT&T have the 10-digit WEP key located on the bottom of the 2Wire router inside brackets (for example [ xxxxxxxxxx ]). Write down the 10-digit key, exactly as you see it.

For this process to work a network cable will have to be connected between one of the LAN ports on the back of the wireless router and the LAN port on the computer.

Note: For information on where the LAN port is located for your computer, refer to its Quick Start Guide, Setup Guide or User's Guide and look for the section on Connecting the Network Cable. For more information on how to get the documentation for your computer, refer to Dell Knowledge Base article Manuals and Documentation for your Dell Product.
