    Using the Wifi connection to the internet (wireless) to building Wifi, the signal strength is strong but the speed is poor. My regular desktop shows speeds are fine (used in the same area). (Desktop >16Mbs...Laptop <1 to 4.5Mbs.

    Dell help is non existent. Computer given to me by son of recently deceased friend,

    The laptop's wireless speed depends on the wireless card inside it. Look in Device Manager > Network adapters and post what it shows for the wireless adapter please.

    I loaded file into my regular computer.
    See attached. Note adapter was updated (actually never updated) it was updated, same as original. Problem may be Vista.

    I fix computers for schools, charities, etc. for nothing. This one also has a dead battery

    That's a G rated card with a top speed of 54Mbits/second which is 6.75Mbytes/s, you're speeds aren't too bad. If you want to increase the wireless speed check if your Router can do wireless N, if it can you could fit a faster wireless card into the laptop. N can be nearly 3 times faster than G. There is an even faster type called AC but I'm not familiar with that.

    EDIT : I have to go now, will check back here later.

    has the driver been updated ?

    try letting windows re-install - see below
    also a tcp/ip reset may be in order - see below
    finally lets see an xirrus screen shot, to see the type of signal strength you are getting - see below
    sometimes its worth removing the wireless card and reseating , the card and aerial leads

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

    Try reseating the wireless adapter

    If the adapter is easily accessible, usually through a cover on the bottom of the laptop.
    Remove the power adapter and also the Battery before doing the following
    Remove and reinsert carefully and firmly several times to cure any possible looseness or corrosion.
    At the same time check to make sure the antenna leads are securely attached.
    Note: This is not taking the machine apart. We do not recommend removing the keyboard when that is necessary to find the wireless.

    There are often some good examples of how to disassemble laptops on "youtube" and you should see if the wireless card is on the bottom of the laptop

    Heres an example (they do vary) of a wireless card - with the clips where the aerial leads usually clip

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

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

    Uninstall and allow windows to re-install the adapter and Driver
    goto the device manager > Network Adapters > click on the [+] to show all the adapters

    right click on the adapter and from the menu

    remove/uninstall the adapter

    Now restart the pc and allow windows to detect new hardware and re install the adapter and the driver

    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 to the faulty PC 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.

    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://go.pardot.com/l/66982/2015-01-26/2361i
    enter you details
    Download this file "DOWNLOAD WI-FI INSPECTOR Vx.xx "
    ( the site now appears to allow webbased emails like gmail, hotmail, outlook and yahoo now )

    There is also a xirrus gadget, But that does not have all the fuctionality "DOWNLOAD GADGET Vx.xx

    Alternative links - Use the links below
    http://www.softpedia.com/get/Network-Tools/Network-Monitoring/Xirrus-Wi-Fi-Inspector.shtml


    Then run and install the program - on a wireless enabled PC/Laptop
    if you get an error - You 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/xirruswifiinspectorguide1-2-0

    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)


    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

    Under speedtest.net the results are in 'Mbs' and according to your info it is Megabytes. Usually I see MBs as Megabytes. Thanx for the tip.
