    I have a very irratating problem that i just can't seem to resolve. My lap top, about a year and half old (Asus g73sw), has decided to begin randomly dc'ing me from wifi networks. This problem is completely random and happens wether my lap top is just idle or if i'm in the middle of a league of legends match. So here's the problem: I'll be online and all of the sudden web pages stop loading and my wifi connection either is totally lost, or is usually available but with "limited access". I have already made sure my wifi capabilites are completely turned on, tried connecting to other networks (same problem), and updating wireless drivers. In addition, i bought a wireless internet adapter (thinking it could possibly be my wireless card going bad) and the problem was not solved at all. One thing to note is that i have absolutly no problems if i connect to my internet via ethernet cable. any ideas of what it could be? btw, it says my ipv4 & 6 are not connected or available or w/e. Any help would be greatly appreciated :D Thanks in advance!

    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, kaspersky or Mcafee or any free security suites like zonealarm, AVG , Webroot etc
    lets see the following please

    ipconfig /all
    xirrus screen shot

    also do a TCP/IP reset - see below

    ------------------------------------------------------------------------
    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 8
    to open a Cmd Prompt or an Administrator Cmd prompt from the Desktop. Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.

    This should work for all windows version, XP, Vista, W7
    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 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.

    Wi-Fi Inspector | Xirrus
    Direct link to the program is here Wi-Fi Inspector Confirmation

    {If the above link does not work heres another link Xirrus Wi-Fi Inspector | PCWorld}

    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.
    Windows XP
