    Hi

    i have an E-system 3115 laptop and have managed to connect to the internet using an ethernet cable to my Scientific Atlanta modem, but what i want to do is connect the ethernet cable to my Belkin Wireless G+ MIMO router and go online wirelessly.

    I'm having problems doing this as it only seems to work when the cable is plugged into the laptop.

    Thank you if you can help me.

    Right click my computer and choose manage, then select device manager. If there is any yellow ! or ? or red X then there is something going on with the device. It may not have a driver or it may be turned off. Next you want to make sure your laptop's wireless switch is turned on. It will either be a physical switch on the front or side or it will be a function button combination. That mean hold down the button with Fn on it and find another key with the wireless symbol on it. Hope this helps.

    Let's see this for the machine.

    Hold the Windows key and press R, then type CMD to open a command prompt:

    In the command prompt window that opens, type type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    Well, DHCP is not enabled on the wireless connection, that's one issue.

    Configure DHCP for Windows Vista.

    1. Click on the Start menu, and select Control Panel.
    2. Click on Network and Internet. (Skip this step if you do not see this Control Panel item.)
    3. Click on Network and Sharing Center.
    4. Click on Manage network connections.
    5. Right click on Local Area Connection and choose Properties. If Windows say it needs your permission to continue, click Continue.
    6. Select Internet Protocol Version 4(TCP/IPv4) and click Properties.
    7. Select Obtain an IP address automatically.
    8. Select Obtain DNS server address automatically.
    9. Click OK to close the TCP/IP Properties window.
    10. Click OK to close the Local Area Connection Properties window.
    11. Click Close to close the Network Connections window.
    12. Click Close to close the Control Panel window.
    13. Restart your computer.


    Next, you appear to have the wired connection directly to a modem, since you have a public IP address. If this is a router connection, it's not connected to the modem correctly. The modem connects to the router's WAN port, not one of the LAN ports.

    To test to see if your router is working plug the modem into the router and plug a cable from the router to the laptop. I'm not sure if you know or not, but the modem has to be plugged to the wireless router for the router to send wireless internet signal.

    Actually, the modem does NOT have to be plugged into the router for the router to accept wireless or wired connections, you just don't have Internet access.

    You might want to try some of this stuff before expounding on it here.

    i have followed all your steps regarding internet protocol 4 and re-started but still no wireless connection yet as soon as i put the ethernet back in, the internet is working fine. We are using a Belkin Wireless G MIMO router, but have a netgear router spare, should we try un-installing the belkin and trying to re-install via the netgear router?

    Let's start from scratch.


    The following procedure should get you a connection with any broadband modem that is configured to use DHCP for the router connection, such as cable modems, and many DSL modems. If you require PPPoE configuration for the DSL modem, that will have to be configured to match the ISP requirements.

    Note that the wireless encryption and channel selection will have to be done after the basic wired connection is established, the first step is to get wired connections working.


    • Reset the router to factory defaults by holding the reset button down for 15 seconds with power on.
    • Turn off everything, the modem, router, computer.
    • Connect the modem to the router's WAN/Internet port.
    • Connect the computer to one of the router's LAN/Network ports.
    • Turn on the modem, wait for a steady connect light.
    • Turn on the router, wait for two minutes.
    • Boot the computer.

    When the computer is completely booted, let's see this.

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous command output!

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

    IPCONFIG /ALL

    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>

    PING 206.190.60.37

    PING yahoo.com

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    <computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

    <default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

    <dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.


    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.
