    I recently swapped out my netgear firewall and linksys wifi router for a combo unit, cisco wifi router and firewall in a single device. I set up the new device on the same subnet to make things easier for my small home network.

    Everything works fine for all of my devices (which include desktops, laptops, and iDevices), as well as a Kindle-Wifi. Except for two laptops, which both happen to be running WinVista. I have a desktop and a laptop that both run Win7, as well as a Mac with OSX Lion, 3 iphones, and 2 ipod touches. All of these devices were able to connect to the new SSID, which was the same as the old one.

    The two machines with Vista were not able to connect to the same SSID, even though they could both be "seen" on the network. They kept saying there was a timeout during the authentication process. I have deleted the existing wifi connection and allowed the machines (both laptops) to recreate them automatically, but they still won't connect.

    These two Vista machines are able to connect to other wifi SSID's, as I created a "guest" connection on my new router, and was able to get these machines onto the internet, but they have to type in a password once a day.

    Is there something in Vista that would prevent it from connecting, or am I stuck with "guest" access for these two machines?

    some adapter are an issue on vista - i have posted the details at the bottom of the post - but we need to see an ipconfig /all to see if it is the adapter

    take the wireless security off the router and see if they now connect
    make sure a firewall / security suite is not blocking - like an old trial version of mcafee/norton

    take off the wireless profiles - see below

    post back an ipconfig /all and a xirrus screen shot from both the laptops - give each laptop a name and use that when posting details , so we can track which is which



    ------------------------------------------------------------------------
    ipconfig /all
    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

    We would like to see the results from ipconfig /all post back the results in a reply here

    Hold the Windows key and press R, then type CMD then press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):

    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    ipconfig /all > network.txt & network.txt

    It will export the results to notepad and then automatically open notepad.

    Now all you need to do is copy and paste those results to a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will be highlighted
    Next
    From the notepad menu - choose Edit - Copy
    Now go back to the forum - reply and then right click in the reply box and paste

    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 paste here.


    http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
    Direct link to the program is here http://wpc.475a.edgecastcdn.net/00475A/XirrusWiFiInspectorSetup.1.2.0.exe

    {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 NET Framework installed for the WiFi Inspector to function.

    Run the program

    A user guide is available here http://www.xirrus.com/Products/Wi-Fi-Inspector/xirruswifiinspectorguide1-2-0.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, and also post which network "Adapter Name" (1st column) is yours on the list

    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
    To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.
    Full details are 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.

    Atheros Wireless Adapter - AR5007EG & AR5007
    Over the last couple of yars we have been seeing a lot of problems with the above adapter over the last few months, mainly concerning WPA and WPA2 encryption and windows Vista.

    The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

    Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
    --- Please post back here if that
    works or does not work.


    Here are a number of possible solutions

    --- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

    --- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.
    Toshiba - update has worked for some PCs
    HP The latest HP Atheros driver dated Sept 2010 has fixed the issue - so check the driver date, However, that does NOT apply to all HPs / Compaqs machines
    - the poster did an online scan for driver updates on the HP website here HP Product Detection which resulted in a solution. Solved: Can't connect to internet wirelessly - Atheros AR5007 Wifi through Clear Comm - Tech Support Guy Forums

    If you can post the Make and EXACT model of your PC here, along with the windows version you have and we will see if we can find the driver and will post a link as a reply here.

    --- 3) On one occasion re-setting the router back to factory default and re-configuring the router settings has resolved the issue

    --- 4) A few posters here with the same issue have found that the driver from this site ATHEROS drivers for Microsoft Windows resolved the issue
    Threads are here
    Solved: Public Network - Access: Local Only (Please help!) - Tech Support Guy Forums
    Solved: NetGear WNDR3700 Incompatibilty W/ Atheros AR5700 - Tech Support Guy Forums
    Solved: Local connection only when connected to secured wirless - Tech Support Guy Forums
    Solved: Unidentified Network - Tech Support Guy Forums
    Unidentified Network


    I do NOT know anything about the site mentioned ATHEROS drivers for Microsoft Windows However, a number of forum members have now successfully used the site to update the driver

    However, if you do decide to try the driver, Please let us know the outcome

    Direct link to the drivers are below
    You only need to click on the green download button labelled " click to download " and wait, the file will download - you do not need to click on any other buttons to get the download started

    AR5007
    Vista 32 Bit
    Drivers for Atheros AR5007 and Windows Vista
    Although this driver has shown up in BSODs (Blue Screen Of Death) on Vista SP2 systems, usually conflicting with updated Vista OS drivers like netio.sys, tcpip.sys and other networking related drivers.

    AR5007EG
    Vista 32 Bit
    Drivers for Atheros AR5007EG and Windows Vista

    Drivers for other windows operating system
    http://www.atheros.cz/atheros-wireless-drivers.php

    Assuming that after all the above the wireless still does not connect to the internet, all I can suggest is to use wireless security of WEP or to get an external USB wireless card.

    You might also bug your laptop's tech support about the problem--maybe people can put pressure on Atheros to find a fix.

    Are you using service pack 2? I know authentication issues were addressed in the SP2 update for vista. Did you say that when you change the ssid of the router you can connect? If so, then just change the ssid. Are your wireless network adapter(s) set to use "mixed content" meaning 802.11 A/B/G/N?
