    Hi guys. I have a huge pain in the butt problem here. This problem I have has been ongoing for a few years. I just really want to fix it now as I am downloading and streaming more :)

    Basically my Local Area Connection decides to crash whenever I am downloading at high speeds. It even crashes sometimes, though rarely, when I'm watching just a single youtube video. Mostly though it crashes with the high speed downloads from certain websites or my cloud storage.

    My modem looks fine when this happens, all lights blinking correctly. Besides restarting the modem does nothing. Basically I've narrowed it down to a cpu/network problem. I try to repair the connection or diagnose a problem and nothing works. I try to reset the adapter but that does not work. I'm not sure if this means anything but where it is supposed to say "This device is working properly" It will say "There is no driver installed etc." If I click on the driver tab it shows the most recent driver....but under the info tab it says there is no driver installed. I also get a lot of freezing when I try to troubleshoot. If i try to disable/enable or uninstall/reinstall the window will freeze and I have to "hard close" it. So after it crashes I can't seem to do much because it just freezes when I try anything.

    I uninstalled the driver and updated to the most recent one but that didn't fix the problem. I assume that covers uninstall/reinstalling the network driver?

    Anywho heres some basic info

    1. I use Windows Vista 32bit
    2. I use Cox Communications internet Ultimate Tier Package
    3. My modem is a motoralla SurfBoard sb6180
    4. I use paid AVG 2012 Business Edition and Malwarebytes. That's the only other software running pretty much.
    5. I have a Dell XPS 720 H2C, quad core

    Here's a speed test so you know I'm not lying heh

    Ok that is all I can think of for now. I've narrowed this down to network issue on my computer NOT MY MODEM. I do not use a router and I am the only person on the network in my house. A reboot is the only way to reset my local area connection. I've tried repairing, uninstalling drivers etc to no avail.

    Should I post an IPCONFIG when the disconnect happens, would that be helpful?

    It sounds to me like an ethernet adapter or motherboard problem.

    But first I suggest that you uninstall AVG and run the Remover. After testing long enough to determine that AVG is or is not causing the problems you can reinstall it. Obviously before uninstalling it you want to make sure you know the product key or whatever you need to reinstall.
