Issue 1:What is WiMAX?


WiMAX is a next generation wireless network communications technology. WiMAX is similar to Wi-Fi, except that WiMAX provides high-speed, broadband access at speeds similar to DSL and cable connections over a much larger area. For fixed WiMAX stations, the range of coverage may encompass several square miles. WiMAX networks also enjoy less interference than Wi-Fi.

WiMAX Benefits

  • You could be in a bus traveling across the city, and remain continuously connected to the internet.
  • Video conferencing from the park.
  • Looking up the nearest local bookstore or getting directions to a restaurant while on the move.
  • Downloading movies while at the soccer field.
  • Streaming radio and television broadcasts off the Internet.
  • Staying productive on the road without searching for hotspots.
Is WiMAX Available in Your Area?

WiMAX is coming to cities and localities across the United States.
To determine if WiMAX is available near you, visit the following site:Clear.com.

Issue 3:First Time Connection


  1. During your first connection to a WiMAX network, you will open an account with the WiMAX network service provider. Your laptop will connect to a internet portal managed by the network service provider, where you can subscribe for WiMAX service with the provider.




  2. The exact process for registering and subscribing may vary, based on the WiMAX network service provider. Once the subscription process is complete, you will have full access to the internet via WiMAX. There are two kinds of WiMAX networks, known networks and unknown networks. A known network is a pre-activated network: one already recognized by your computer, A known network has a name (for example, Clear Network), and registration and subscription are easy.




  3. Wi-Fi and WiMAX cannot operate at the same time. When Wi-Fi is connected, turning on WiMAX will disconnect the Wi-Fi.




  4. During this process, your firewall may ask for permission to allow communication between the WiMAX activation and provisioning site, and your computer. To complete the activation process, you will need to permit this communication or see Configuring your Firewall.




  5. Make sure the Intel® PROSet/Wireless WiMAX Connection Utility is running, if not or unsure see the Turning WiMAX On and Off section for more information.




  6. Ensure WiMAX is set to On.

    • After a short interval, a known network (for example, Clear Network) should be listed under Networks available to connect. If a known network is not listed, click Search for Networks, this will perform a fast search. When a known network is not listed after the search completes, see:
      Making a Connection with a Unknown WiMAX Network



  7. Choose a network and connect to it, either by double-clicking it, or by selecting it and then clicking Connect.

    • The icon shows when connected to the WiMAX network.



  8. Open your Internet browser.

Issue 4:Making a Connection with a Unknown WiMAX Network


  1. When no networks are listed, check the following website to determine if WiMAX is available near you, Clear.com .



    • Choose a unknown network and connect to it, either by double-clicking it, or by selecting it and then clicking Connect.

      • The icon shows when connected to the WiMAX network.



    • Open your Internet browser, and follow the instructions to subscribe and activate an account.

    Issue 5:Configuring your Firewall


    For communication to work on the WiMAX network, a specific port has to be open, namely, port number 2948.

    Click one of the three Operating Systems below for instruction on how to open a port in the windows firewall:

    Refer to (Table 1) for links to the most common brands of firewalls for instructions on how to open a port.

    Firewall Vendor Web Site
    McAfee http://mcafee.com/us/
    Norton (Symantec) http://www.symantec.com/norton/index.jsp
    Norton (Symantec) www.citizen-systems.com

    Issue 6:Connecting to a Home Network


    When going to a new city or area, the WiMAX service provider in your previous location (your home network) may also be listed in your new area. If your home network is not listed in your new location, you will need to activate service with a new service provider in the new area, just as you did for the first WiMAX network service provider. To do this, see First Time Connection.

    • Activating service with a new WiMAX network service provider does not cancel or change the agreement you have with your current service provider.


    1. Make sure the Intel® PROSet/Wireless WiMAX Connection
      Utility is running, if not or unsure see the Turning WiMAX On and Off
      section for more information.




    2. Ensure WiMAX is set to On.

      • After a short interval, a Home network should be listed under Networks available to connect. When a Home network is not listed, click Search for Networks, this will perform a fast search. When a Home network is still not listed after the search completes, see the Exhaustive Search section of Searching for WiMAX Networks or check the following website to determine if WiMAX is available near you, Clear.com .



    3. Choose a network and connect to it, either by double-clicking it, or by selecting it and then clicking Connect.

      • The icon shows when connected to the WiMAX network.



    4. Open your Internet browser.

    Issue 12:Error Messages and Troubleshooting


    Not Connected


    You are currently not connected to a WiMAX network.

    This message does not imply an error, but only that you are not connected and there are no home networks available to connect to.

    You can perform a fast network search, which searches for previously connected networks, or an exhaustive network search, which searches for all WiMAX networks, including networks that you have not previously connected to.

    For more information on how to search for WIMAX networks refer to Can't Find any Networks section.

     Note:
    An exhaustive network search may take several minutes and will consume more power than a fast search.

    Unable to Connect to the Network


    This may be for one of the following reasons:

    • You are in an area where WiMAX signal strength is poor. Check the signal strength indicator; the number of green bars increases with greater signal strength and decreases with less. To reconnect to WiMAX, move to an area of greater signal strength. You can contact your service provider for that information at, Get WIMAX .


    • You are in an area where WiMAX signal quality is poor. You may be too close to a wireless access point or microwave oven, both of which can interfere with your WiMAX connection. Make sure such devices are located at least 7ft (2 meters) from your WiMAX adapter.

    • You turned on the Wi-Fi radio. WiMAX and Wi-Fi cannot operate at the same time. Turning On the Wi-Fi radio will disconnect your WiMAX connection, and, turning on WiMAX will disconnect your Wi-Fi connection, for more information on how to turn WIMAX on refer to the WiMAX is Off section.
    • You turned off the WiMAX hardware radio switch. On some laptops, a WiMAX hardware radio switch lets you turn On or Off WiMAX radio. If present, turn the WiMAX hardware radio switch back on, for more information on how to turn the hardware radio switch on refer to the The Radio Hardware Switch is Off section

    • Service from your WiMAX network service provider has been interrupted. Contact your service provider for additional assistance at: Get WIMAX .
