    My sony vaio laptop connected to my wireless network fine for months. two days ago it suddenly stopped connecting. My network still shows up in available list and is at full strength. My wireless printer still connects to the network. Furthermore, my laptop connects to other networks, it just doesnt connect to mine anymore! I am completely computer illiterate so can someone please help me in laymans terms!?

    Hi:Let's get some basics first.
    Any software/hardware changes in the last 2 days ?
    Any error msgs when trying to connect?
    There are a number of things we could suggest doing,but first:
    ,let's see this :
    From a Johnwill post on the Networking Forum

    Try these simple tests.

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

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

    NOTE: For the items below surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work. Also, the < and > in the text is to identify the parameters, they are also NOT used in the actual commands.

    Do NOT include the <> either, they're just to identify the values for substitution.


    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>


    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. (For Vista/Win7, the IPv4 Address)

    <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.

    First Name:
    Suggest you first try either

    a. disable encryption on the router and try to connect; if successful you can probably re-enable encryption and reconnect. Or,

    b. delete your wireless profiles; scan for your network and try to connect.

    Then move on to pedroguy's post.
