    What happens is, I will be randomly disconnected and unable to connect to the internet on this computer (not the main one), until I unplug/re-plug in the eternet cord from the tower. I run my computer off a wired connection from my main computer's modem. The strange thing is, the main computer is never affected and the internet connection always remains. I find that this most often happens when I am either running a lot of programs, or playing video games (though that could just be a coincidence). I've tried everything from replacing the eternet cord to changing modems and nothing has helped. I've also tried googling my problem but did not come across anyone with a similar situation. When I contacted my internet service provided, unsurprisingly they were unable to provide much help. This problem can be rather irritating, and I would like to get it solved. I am desperate for an answer! Can anyone assist me with this problem!?

    Thanks!

    would you supply
    Make and model of the PC
    Make and model of Router/Modem

    The PC may need a driver update

    Would you try using the PC in safemode with networking
    as the pc starts keep tapping F8 until a menu appears then choose
    safemode with networking
    see if it disconnects while in this mode

    also post back the following when in normal mode - 1) when its working correctly and 2) when it disconnects
    make sure we know which is which


    ------------------------------------------------------------------------
    {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

    Sorry that it has taken me SO long to respond...I actually forgot that I posted on this forum. >.< Listed below is my information:

    Computer:
    Windows 7 32-bit
    Pentium(R) Dual-Core CPU
    4.00 GB (RAM)

    Modem:
    Bell 2Wire Gateway (White Modem)
    2701HG-G (Model Number)

    I tried updating the network adapter (Realtek PCIe GBE Family Controller) driver, and that also did not seem to work. The disconnection does not appear to have a pattern, and just happens randomly disconnects. II'll try running it in safe mode and post my results! :)

    As posted above
    Make sure we see all the PINGS

    How often ? you may not be able to use the PC fully in safemode and if it takes days before it disconnects make sure the PC will do all you need while in safe mode - it uses a VGA graphics driver - so games will not look good or run at all

    As for safe mode...I don't think my problem occurs often enough to remain in safe mode for a long period of time. Usually happens about once every 3-6 hours.

    so that has lost connection to the router - is the light still on the router for the cable connection?

    I assume the other PC is still working OK on the router

    try this

    start>
    in the search box - type
    CMD
    a black box will open
    type

    ipconfig /release
    ipconfig /renew

    and then repeat the tests - see if that reconnects ?

    if not then

    TCP/IP stack repair options for use with Vista/Windows 7.

    Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    Note: Type only the text in bold for the following commands.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log

    Reboot the machine.

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

    post back any errors or access denied

    I repeated the first step several times, but it did not bring back my connection so I immediately did the second step. I'll report back if I get disconnected again. It seems like it is happening a lot more often today.

    Is there any chance that there could be too much going on for the internet to handle, so it disconnects me as a result?


    Edit:
    When I spoke with my internet company, they "claim" it is not the modem, but my computer hardware. I have no clue anymore. v.v

    MSE is not a firewall its an antivirus/malware program

    Do you have a program like Norton or Mcafee on the PC ?

    When you ran the TCP/IP repair - did you get any errors or access denied errors ?
    would you do again and post back the results from that screen

    No - you should have a solid connection all the time
    from you first post I agree
    Hence the question I asked again in post #8 just to confirm
    So is he other PC solid on the internet all the time and whenever you are disconnected

    Lets see if there is an updated driver for that machine - what's the make and exact model of the PC
    post back a screen shot of device manager

    ------------------------------------------------------------------------
    {Device Manager}
    Post back the results in device manager
    If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
    Start > control Panel {Vista set to classic view}> system > {Vista, device manager on left hand side} {XP hardware Tab, device manager button} >
    windows 7
    start > control panel> System and Security> Device Manager

    network adaptors, click on the + >

    post a screen shot of the device manager - network adapters

    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

    Yes, the other computer is always solid. When this connection disconnects, the other computers connect remains. I just find it strange that as soon as I unplug the cord from my computer, and then immediately plug it back in, that I get back the internet connection instantly.

    The other computers information is listed below:
    MDG Computers Canada
    Windows XP Media Center
    Intel(R) Pentium(R)
    2g of ram
