    you have a few connections there and one has an IP address
    Wireless LAN adapter Wireless Network Connection:
    may want to remove these
    how to show the IP and DNS settings screen
    Start> {search bar in Vista/W7}> type ncpa.cpl
    that should open your "network connections" dialogue box
    post a screen shot -see below

    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG etc


    would you post some ping tests - see below

    ------------------------------------------------------------------------
    Ping Tests
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

    Start> Run {search bar in Vista/W7}> type CMD to open a command prompt box
    (A new dialogue box - black with white font, will appear on screen ):

    Type the following command
    Ping 192.168.43.1
    Post back the results in a reply here
    right click in the command prompt box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping google.com
    Post back the results in a reply here
    right click in the command prompt box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping 209.183.226.152
    Post back the results in a reply here
    right click in the command prompt box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    ------------------------------------------------------------------------





    To post a screen shot of the active window.
    1) hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    OR
    2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

    To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.

    Disable Wireless Network Connections 3 and 2. Run ipconfig /release, ipconfig /renew. Try pinging your gateway; setup IP and DNS address manually and try again. check if your router needs firmware upgrades.

    if you've done your home work, Local Area Connections 2 and 3 would not be in results of ipconfig. You should disable them (right-click in Network Connections window and chose disable). If you are able to connect to the same router with Ethernet cable and browse internet, do so - connect with Ethernet cable and also connect to your wireless network, confirm that. Then go to command prompt and issue ipconfig /all. Compare results under Wireless LAN adapter Wireless Network Connection and Ethernet adapter Local Area Connection. Subnet Mask, Default Gateway and DNS server addresses should be the same, last number in IPv4 Address shuold be different. If you get auto-configured address like 169.254.xxx.xxx, set it up manually 9along with subnet mask, gateway and dns addresses) for wireless adapter and try to ping your gateway and google.com. If you can connect wirelessly to othe networks, check setting on your router, or maybe it would be easier to reset it. Also go to manufacturesrs web page and see if any firmware updates are available.
