    Hey Guys,
    This is basically my problem. It has been going on for a year or so now but since i was usually living at an apartment/college dorm i did not really care about till now since ill be living back home again.
    My network just keeps randomly dropping. I am a professional gamer and need to fix this program to play to my utmost level in the game im devoting quite a lot of time to. This is what happens:
    I am doing whatever/browsing the net, on skype, or in a game and the net just randomly drops. Ive tried to pinpoint a pattern but cant find any really. Some days it happens a lot, some days it barely happens (like 3 the whole day). It drops for like 30-40 seconds AT worst and then comes back fine. Also sometimes the ping just randomly goes really high for a few minutes. I usually get d/ced from whatever game im in. I called my ISP and told them the problem. On my Modem page(192.168.0.1), i saw the event log and whenever i actually d/ced, a warning came up.
    it said this:

    Time:12/18/11 20:09:37, Level:critical, Content:No Ranging Response received - T3 time-out

    etc, happens every time a d/c occurs. They end up sending a tech, he did some tests inside the house and then went ouside and did some tests as well and came back and said he didnt see anything wrong.
    He switched the routers with a new one he had because in the end thats all he could do cause he didnt know what the hell was wrong. He left, i turned back my PC and boom the disconnect occured 45 minutes after.
    Case in point: i have no idea what the problem is, i dont know exactly what to show my ISP. They can see the random router disconnects on their end as well. The tech guy comes in and monitors the net but obviously the d/c doesnt happen when hes here since its so intermittent and random.

    Anyways what do i do? Any program to help show them my claim? any way to suggest to my ISP what to fix such as network cables?
    this happens on both my laptop (wireless) and my wired connection on the PC. the d/c happens at the exact same time on both.
    Thanks for the help.

    is this happening on all PCs connected or just yours ]
    Sounds like a router / cable / line problem

    who are you connected to the ISP - cable or telephone ?

    Whats the status of the lights on the modem/router when working and again when disconnected

    can you post the following when its working and then see if you have time to repeat all the tests while its disconnected



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

    This is a ping to google when i am actually lagging HARD on the network which occurs randomly. this isnt the disconnect ping since i didnt get it in time but this is my Ping when my net just randomly lags.

    sounds like a modem / line /cable /isp issue - if all devices connected to the router disconnect then i would look at that

    it may still be a DNS issue - hence the need for the second two PING tests - one to google and one to an ip here
    can you do those ?

    This was on the the last ping test you told me to do.

    Looks like this may be the problem?

    also my modem was replaced when the tech came in yesterday.

    looks like an unreliable connection intermittent problem - but needed to see the ping to google.com as well - three PING tests

    Is the modem on a telephone or cable

    whats the make and model of the PC - i think a driver update may be in order

    also try google open DNS - unlikely to help - but eliminates another possibility


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

    Google public DNS

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

    Theres also a link on how to setup those DNS IP address
