    Hi,

    A couple of days ago my home PC stopped connectingt to the internet using wifi and hasn't been able to since. However I can on my laptop and tablet! I have taken my PC downstairs to see if I can connect using an ethernet cable which i can.

    I need to find out why I cant now get on it wirelessly. The Pc's about a year old and has an 802.11n Wireless LAN Card. I have reseated it in case it was that.Within Device Manager it says 'The device is working properly'.

    Im at a bit of a loss, any suggestions greatly appreciated

    Might take a look under “Network and Sharing Center” and go to “Manage wireless networks” and delete your network connection from the list and then try to reconnect. Also look under “Change adapter settings” and check that that wireless network connection is enabled.
    I’m assuming this is a Windows OS…

    please post an ipconfig /all and an xirrus screen shot
    ------------------------------------------------------------------------
    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 the results in a reply here.
    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.

    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
    Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

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

    For windows version, XP, Vista, W7
    Hold the Windows key and press R

    Now type CMD

    Now 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 into notepad and then automatically open the notepad and display on your screen.

    Now all you need to do is copy and paste those results into a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will now be highlighted
    Next
    From the notepad menu - choose Edit - Copy

    Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
    The results from the notepad should now appear in the forum reply.

    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, so try the direct link below)
    Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

    {If the above link does not work heres alternative links
    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
    http://download.cnet.com/Xirrus-Wi-Fi-Inspector/3000-18508_4-75758254.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/Xirrus-Wi-Fi-inspectorguide-1-2-1-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 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

    To post a screen shot of the active window.

    Vista or Windows 7
    you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool
    http://www.bleepingcomputer.com/tutorials/how-to-use-the-windows-snipping-tool/


    To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.

    Did you delete your wireless profile, as CoolBurn suggested?

    Disable encryption on the router and try to connect. If successful you can probably re-enable encryption and reconnect.

    There was no profile to delete and reconnect! My wireless network says 'Not connected' in 'Change Adapter Settings'. And yes it's Windows 7.

    The wireless card MAC address is set to the following values. Try going to device manager and right-click the wireless card - Properties - Advanced tab. Look for the values on quote by highlighting Property on left side then use or tick not present (if available) then hit Ok. See if you can connect this time on wifi by removing the wired connection.

    Hi Jayhz,

    Apologies for replying sooner, have been away.

    I checked for what you said but it's already ticked on 'Not present'

    Still stumped!

    Can you borrow a USB wireless adapter? It seems that your wireless card is faulty.
