    My older brother and I recentely bought the HP Spectre XT ultrabook and I've started noticing that my laptop seems to be alot slower when connected to the WIFI. Using the cable works fine but as soon as I switch back to the wireless, it has this tendency to work for a minute or two at 5-4 bars (signal strength) and then suddenly drop to 2 bars slowing the connection significantly. This happens ALL the time making it extremely frustruating for me to browse the internet. I know it's my laptop that's in fault as I had the same problem when using a different wireless at a friends house. I'm not very good with this kind of problems so any help would be greatly appreciated!

    Run Xirrus Wi-Fi Inspector
    Download and install

    If you cannot access the internet with this PC, then you will need to copy theprogram across to the faulty PC
    Save the file to a USB flash drive or other removable media. Plug it into theworking computer with internet access and copy the file and install theprogram.
    You will now need to take a screen shot and copy that back to the working PCand attach the screen shot in a reply on the forum here.

    If you do not have another PC - do you have a phone connected to the internet -can you photograph the result and post the image in a reply

    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx( the site now appears to require a business email, so try the direct linkbelow)
    Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

    {If the above link does not work heres alternative links

    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 tofunction.
    On windows 8 - (i do not have windows 8) but, it would appear that, When youfirst try to run, you may get a message that .net framework is needed, andincluded 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...-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 wecan see all the network information.

    post which SSID name is yours, itslocated in the list, under network "AdapterName" (1st column)

    For a reliable (or robust as the Xirrus user guide says) wireless connectionyou need a signal of about -70 dBm or better. "A desirable signal levelfor 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

    To post a screen shot of the active window.
    Windows XP
    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.

    Vista or Windows 7
    you can use the "snipping tool" which is found in Start> Allprograms> Accessories> Snipping Tool

    To upload the screen shot to the forum, open the full reply window ("GoAdvanced" button) and use the Manage Attachments button to upload it here.
    Full details are available here http://library.techguy.org/wiki/TSG_...g_a_Screenshot

    Install the latest driver for the wireless adapter. Get the driver from the laptop manufacturer's web site if the adapter is integrated. Otherwise from the adapter manufacturer's site. If you already have the correct driver reinstall it anyhow in case the installed instance is corrupted.
