    Hello everyone!

    I am literally at the end of the road here, I have read so many forum posts and taken so many pieces of advice but nothing seems to be working.

    I am unable to connect to the internet on my desktop PC despite the fact it is pretty much next to my router and I am using a brand new wireless adapter.

    I recently reformatted my old desktop PC, I installed some new RAM and added an additional Hard Disk.

    I reinstalled windows XP professional with sp2.

    I have just purchased the TP-LINK NANO USB ADAPTER (literally the newest model), I installed the drivers and software as stipulated on the box and the adapter appeared to work initially (albeit a little intermittently). I was able to download all of my audio and graphics drivers and able to download XP sp3 off the microsoft website and install it.

    Since installing SP3 (and .NET framework 3.5) the wireless adapter essentially refuses to connect... a problem I have had so many times when trying to add wireless adapters on XP systems.

    The PC finds my router, and either spends five minutes attempting to 'acquire network address' or connects but doesn't display anything on the screen when I open one of the browsers.

    Running various tests and diagnostics, it seems like the PC cannot renew it's IP address?

    Computer is currently showing the 'limited or no connectivity' icon despite being 'connected'.

    Please help!

    p.s. Might also add I have removed and reinstalled the drivers for the TP-LINK device that came on the CD
    System: XP sp3
    RAM: 2GB DDR2
    Processor: Intel Core2 duo [email protected] 1.800GHz

    is this the model
    http://www.tp-link.com/en/products/details/?model=TL-WN725N

    drivers are here
    http://www.tp-link.com/en/support/download/?model=TL-WN725N&version=V2#tbl_a
    maybe worth trying one of those

    can we see an xirrus screen shot

    ------------------------------------------------------------------------
    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.

    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, and does not allow webbased emails like gmail,hotmail or yahoo etc )

    Use the links below

    http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html
    http://www.softpedia.com/progDownload/Xirrus-Wi-Fi-Monitor-Download-99109.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/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

    Ok trying the drivers from the website didn't help, appeared to be the same version as was shipped with the nano TP-LINK USB wireless adapter.

    Here is a screen shot as requested, thank you for all your help!

    thats not a good signal -71 -
    which maybe the reason for
    on a desktop - they are often plugged into the rear USB , which is against a wall or in a cabinet and not the best location for picking up a good wireless signal

    can you try the front USB sockets if available

    do you have a laptop at all

    Looks like the signal may have been the problem! I have just pulled the PC out of the desk enclosure, it is now working!

    It is really infuriating that the router is only in the next room but the signal is so poor!

    I also have an old PCI wireless card somewhere, I wonder if that would be better or if it would encounter the same issues?

    When I put this PC together there were no slots for front facing USB slots so I put them all to the back. Would a USB extention cable work? if I ran the cable to the front of the machine?

    Thank you for all your help!

    sounds like it might - if you are able to get it to work by pulling the desktop out
    would depend on the sensitivity of the aerial(s) , only way to be sure is to try it
