    I am having connection problems with my internet. I just bought a new router: Netgear N600 Wireless Dual Band Router (WNDR3400v2) and I am already having problems with it.

    First the wireless connection on my Laptop (Windows 7) and my nephew's Samsung Galaxy Tab (Verizon) is like super slow, takes a very long time for pages to load on my Laptop and on my nephews Samsung Galaxy it drops connection when he's playing a game and I don't know why.

    My internet provider is ClearWire and the Modem is a Motorola CPEI 25725.

    Also my main computer which is a Windows XP is disconnecting from the internet at random. It says that my Realtek RTL8139/810x Family Fast Ethernet NIC keeps being disabled and I never had that problem with my other linksys router: WRT54Gv8 until I got my new updated router N600 WNDR3400v2 from Netgear.


    I don't know what to do or try. I even tried unplugging both devices and reconnecting them but still I get the same results.

    thanks to anyone who can help.

    how often - can you connect directly to the modem and then ensure that it nolonger disconnects - that at least proves the modem and connection is OK

    then connect router and do a powercycle (see below) - and do the following tests

    would you post the following tests when its working OK and then repeat ALL the tests when it disconnects and make sure you also tells which tests posted are for what condition


    ------------------------------------------------------------------------
    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
    ------------------------------------------------------------------------

    ------------------------------------------------------------------------
    Ping Tests
    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
    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.

    Start> Run {search bar in Vista/W7}> CMD to open a DOS window and type:

    Type the following command
    Ping {plus the number thats shown against the default gateway shown in above ipconfig /all}
    Post back the results
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping google.com
    Post back the results
    rightclick in the box
    select all
    enter
    control key + C key - to copy
    then reply here and
    control key + V to paste

    Type the following command
    Ping 209.183.226.152
    post back results
    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
    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 ("Go Advanced" button) and use the Manage Attachments button to upload it here.
    Full details are here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot

    Or if you are using Vista/Windows 7 you can use the "snipping tool" which is found in
    Start> All programs> Accessories> Snipping Tool

    Note:
    For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better.

    If you are using the Mac OS then use http://www.istumbler.net/ or
    if you want to optimise base station position and signal strength / dead spots use
    http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

    How to power cycle

    “power cycle” process to reboot or reset the modem/router
    • Switch off all the devices modem, router and computers also unplug their power cables.
    • Wait at least 1 to 5 minutes,
    • Plug the power cords back in, but don’t switch them on.
    • First turn on the modem and then wait for a few minutes for it to settle and all the lights to become stable.
    • Next switch on the router (if a seperate device ) and then wait for a few minutes for it to settle and all the lights to become stable.
    • Now turn on your computer, You should now be able to access the Internet.

    Thanks for the reply and I am very sorry for the late reply. I did a few test in which I finally figured out why my Realtek RTL8139/810x Family Fast Ethernet NIC was being disabled.

    I installed the NETGEARGenie and that software was messing with my Realtek ethernet card so I uninstalled the software and haven't had a problem since. My connection is solid.

    However I had to move my modem to another part of my room and now I am using a USB Wireless LAN Card instead of the Ethernet NIC. I am planing on buying a longer Ethernet cable and run it from the router to my computer but thats gonna have to wait for now.


    Thanks again for the help.
