WPA2 in Windows XP SP3

    Question

  • I had to reformat and reinstall my laptop today.  After researching, I discovered that WPA2 was implemented with Windows XP SP3, so I didn't worry about applying the WPA2 patch to my XP SP2 installation.  I installed the OS, then installed SP3 before installing the wireless driver for my laptop.  After installing the driver and trying to add a new wireless network, there were no options for anything but WPA.  I have reinstalled SP3 to no avail.

     

    I have also found that after installing the WPA2 patch on a Windows XP SP2 laptop and then installing SP3 the WPA2 options are all gone.  This is really dismaying since I often would rather use the Windows sytem drivers for my wireless connections than the vendor software which usually takes up more system resources.

     

    Bottom line: I can't get WPA2 installed or working on a laptop with XP SP3 installed.  Can someone tell me what to do about this?

  • Ok, I uninstalled the wireless card and reinstalled it in Device Manager and all the WPA2 encryption modes are now visible.  I was able to establish a connection to my wireless network using WPA2-PSK.  Thanks for looking and hope this helps someone else.

  • That's very strange, as WPA2 is included in SP3.  I can think of the following possibilities:

     

    1. Please check to see whether your wireless card needs a driver update from the wireless manufacturer.

     

    2. There are things that can go wrong during the SP3 updater process that lead to subsequent wireless connection problems.  The most frequently seen problem of this nature is if a Norton product is on the PC while the SP3 updater was running.  This leads to a conflict producing many unnecessary registry keys. See http://support.microsoft.com/kb/953979 for a fix procedure.

     

    3. Check to see whether the wireless card is under the control of Windows, or under the control of an application that was supplied with the card's software.  You might have to turn off any such application to enable Windows to gain full control of the card.

  • Thanks for your response.  I can address each of your thoughts easily.

    1. I updated the wireless card driver and all other hardware drivers before running SP3.

    2. No antivirus software was installed at the time I installed SP3.  After installing the OS I installed all the hardware drivers and then updated the OS by installing SP3 and then running Windows Update.

    3. Windows is and was in control of the wireless card the whole time.

    Hope this provides you with enough information.  Thank you again.

  • net-tek,
    Thanks for coming back to this post.  I had the same exact thing and could not for the life of me figure out what was going on.  I tried using the original driver that came with the dell laptop, the newer driver, no driver and nothing worked.  Finally, I removed all instances of the wireless card software and ONLY installing the driver through Device Manager as you suggested and BAM, wireless access! 

    Thanks again!

  • I'm having this same problem.  I have the Atheros AR5005G on a Toshiba Satellite laptop running XP with SP3.  I can't get WPA2 to show up in the list.  I deleted the device and reinstalled but I still don't have WPA2.  The computer that the modem/router is connected to is running XP SP3 also.  I have Windows 7 systems which connected immediately after asking for the security key.  I connect with an ethernet cable to the router and let device manager search for an updated driver but it reported that I have the latest.  Any advice would be greatly appreciated.

  • I ran into the same problem attempting to give my neighbor's laptop access to my wireless network (same laptop, same WLAN adapter, XP SP3, but no WPA2 in the list) and repeatedly updated the Atheros AR5005G driver to no avail.  Looking for a solution I saw this forum.  What I discovered is that updating the driver is just reinstalling the same outdated 3.something driver.   I went to the Toshiba site (aps2.toshiba-tro.de/wlan) and downloaded the current driver (installer) which at this time is 7.7.0.406.2 (many versions later than the 3.something installed by the driver update process) which solved the problem. As you can see from one of the posts above, driver version 5.3.0.35 would have been good enough.

  • I too had the "No WPA2" problem when adding a Belkin wireless usb adapter N150 to XP SPK3.  Removing the software and adding it through the device manager did the trick.  I would add however:

    Have the wireless adapter software CD inserted into your CD drive before starting the install from Device Manager. 

    From the menu bar choose Action, then click "scan for new hardware".

    Select "Install from a list or specific location (advanced)" on the first page of the Found New Hardware Wizard. Hit Next.

    Then check "Search From Removable Media ( Floppy, CD Rom). Hit Next.

    Windows should search and find the drivers on the cd.

    If you have the drivers in another location just check "include this location in the search" and browse to that location.

  • Updating drivers worked here!  Windows XP SP3 with a Broadcom wireless card (HP Pavilion laptop).  Thanks!

    Control Panel > System > Hardware tab > Device Manager > Network Adapters > ... Update Driver
