    I have Buffalo WHR-HP-G300N router with Firmware: DD-WRT v24SP2-MULTI (05/28/10) std.

    I have weird problem.

    Sometimes the Wireless SSID disappears and the router show that every thing is working fine(the wired network is working but not the wireless). After power off and then on the device or after pressing AOSS Button, the router works normally.

    the weird thing that this problem sometimes happen two or three times a day and somtimes once every a week or few days.

    Whats the problem?

    while its working would you post the following information and then repeat ALL the tests again and post those results when it disconnects



    ------------------------------------------------------------------------
    {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 here
    -> Start
    -> (XP - enter the following in the RUN box)
    cmd /k ipconfig /all
    -> (Vista or Windows 7 - enter the following in the Search box)
    cmd /k ipconfig /all

    A black box will appear on the screen -
    rightclick in the box
    select all
    enter
    control key + C key - to copy

    then reply here and
    control key + V to 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

    http://www.xirrus.com/library/wifitools.php
    Direct link to the program is here http://www.xirrus.com/library/wifi_download_redirect.php
    Then run and install the program
    if you get an error - You need NET Framework installed for the WiFi Inspector to function.

    Run the program

    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.

    The router is intermittently failing. Make sure it is not overheating and that there is no problem with the electrical supply (if the voltage dips slightly the radio would be the first thing affected).

    the weird thing that sometimes the signal disappear twice a day and sometimes once a week.

    etaf: when the signal disappears, it is the same as the router off . no SSID , the computer is not connect to any wireless. I connect Ethernet wire to computer and it is working.
