    I have a Sony Bravia KDL46EX640 which comes with a wireless USB adapter. When I first bought this, I set up wireless network and it went fine. I was able to use the applications for video streaming.

    I was trying it again now and it doesn't work. It seems like I can't even connect to my wireless network. I tried to set it up again but it can't find my wireless network. I have tried resetting the TV too (UP arrow + Power button on TV) and still doesn't work. Contacted Sony support but they didn't help at all. I have a laptop and ipad connected to the router in the same room so signal is not a problem.

    Anyone can help me?

    do you have a PC or other devices able to connect to the internet ?

    will the USB adapter work on the PC and detect wireless signals - if you have a laptop can you put it near the TC to see the signal strength

    xirrus is a good program to use to test wireless signals
    ------------------------------------------------------------------------
    Run Xirrus Wi-Fi Inspector
    Download and install

    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
    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 install the program.
    You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

    {If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You need will need to have NET Framework installed for the WiFi Inspector to function.
    On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

    Run the program

    A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus-Wi-Fi-inspectorguide-1-2-1-RevB-6.aspx

    post a screen shot of the program running.
    if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information.

    post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)

    To post a screen shot of the active window.
    1) hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) 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.
    Full details are available here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
    note: the signal level is a negative number, so for example -88 is worst and -40 is better

    If you are using the Mac OS then use http://www.istumbler.net/

    if you want to optimise base station position and signal strength / dead spots use
    http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal
