    Hey guys, I have searched and I'm not seeing anything specifically related to my issue, but I know others have experienced this so I apologize if you end up repeating yourself.

    So, my internet is dropping and coming back. I am using Comcast cable with a Netgear N600 wireless router. My PC is connected directly and a laptop is connected wirelessly. Both the PC and laptop are dropping. I connected straight to the modem and the issue appeared to go away, narrowing it down to the router.

    I have updated firmware and done the normal steps (turn off modem, router, PC, restart, etc...).

    When I pinged google.com, these were my results over a couple minutes or so...

    Code:
     C:\>ping google.com -t

    Ping statistics for 173.194.33.40:
        Packets: Sent = 59, Received = 52, Lost = 7 (11% loss),
    Approximate round trip times in milli-seconds:
        Minimum = 15ms, Maximum = 29ms, Average = 17ms
    
    Those results tell me that it's dropping quite a bit, so I'm hoping anyone has some steps I can take that possibly involve adjusting some settings with the router. Any help is much appreciated!

    Here is what happened. I would assume that since it's still timing out at a similar rate, it would not be a DNS issue?

    Code:
    C:\Users\rdfra_000>ping 173.194.33.40 -t

    Can you test with another router?

    Being that it is connected more than not, how does it affect you use of the system?

    I just ran the same test on my system and see similar results, but it does not impact my internet use in any way...

    can you connect directly to the modem - do a powercycle (see below) and repeat the tests

    lets see an ipconfig /all and see what DNS servers are used and if we can change that to use google open dns

    ------------------------------------------------------------------------
    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.

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

    This should also work for windows 8
    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.
    ------------------------------------------------------------------------

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


    Google public DNS
    Note using google public DNS servers from outside the US may actually slow performace - so use the following as a test to identify DNS issues - if these resolve the issues , then we need to investigate further to optimise the use of DNS


    Google public DNS
    http://code.google.com/speed/public-dns/

    Theres also a link on how to setup those DNS IP address up on a PC
    http://code.google.com/speed/public-dns/docs/using.html

    How to set XP here
    http://techie-buzz.com/how-to/google-public-dns-on-win7-and-winxp.html

    Then once you have set up those DNS entries

    Flush & register DNS

    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 commands:

    Ipconfig/flushdns
    ipconfig/registerdns


    If you receive the message
    The requested operation requires elevation.
    Then please open the command prompt as administrator
    Start> All Programs> Accessories and then right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    now type the command again

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

    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 separate 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.

    So just to confirm you did a constant ping directly to modem and you had no pings drop?
