    Hey, I hope I am posting this in the right place.

    For the past few months, I have been suffering from the most irritating of any computer issues I've experienced. For some reason, every couple of minutes, I will drop access to wireless and wired internet. This began in April, about a week after a fresh install on a PC (it is a very powerful computer, as well). I have multiple other computers/devices connected to the same router by both wifi and ethernet, but only this PC has any issues.

    The first time this occurred, in April, it happened for a week straight. I "cured" it after about 48 hours of troubleshooting by removing a D-Link driver, which was my Wifi driver. I operated on LAN alone from that point (Realtek GBE Family PCIe Controller x2). I assumed the D-Link and Realtek drivers were conflicting with eachother, for whatever reason. It has been flawless, up to about one month ago.

    In May, the same issue began again out of the blue (as soon as I turned my computer on after a weekend away). I lost access to the internet every few moments (at this point, it was wired only). I solved it after a few hours by doing a system restore to about ~3 days prior, when Windows did an update. I assumed a Windows updated restarted the issue with the Wifi for some reason and, once solved, let it be. That is, until it began again.

    As of yesterday, I have been dropping internet every 10-40 minutes, with the longest activity of internet after restarting, shortest after the initial loss (after losing once, I lose it once every 1-5 minutes). I lose both Wifi and Wireless, but do not lose access to the network. I am still sending and receiving packets, but cannot connect to the internet. On the Windows chart, it displays as a connection error at the point of Network, with the Internet being grayed out. Sometimes I will fully lose connection, usually it is "limited connectivity."

    To repair it, I simply "diagnose" the issue with the Windows troubleshooter, and that fixes it for about 1-5 minutes. Changing the duplex/speed also restores it for a few moments.

    What I have tried so far is as much as I can think to do. I've probably put in well over 36 hours of troubleshooting. I have:

    Renewed/Released/refreshed DNS via cmd prompt
    Done SFC scans
    Scanned for any and all malware
    Removed all virus protection software/firewalls
    Tried running at various speeds/duplex
    Turned off ICPv6
    Ran in Ubuntu (issue remained)
    Ran in Safe Mode w/ Networking (issue remained)
    Uninstalled and reinstalled every driver for the network card (2x GBE and 1x D-Link [removed D-link entirely)
    Ensured all drivers up to date
    Turned off WOL in BIOS
    Turned off "energy saving" in the NIC preferences
    Physically molested the NIC (haven't removed it yet, just kinda pushed on it)
    Left the tower without power for 12 hours, while occasionally spamming the power button
    Tried using a USB ethernet cord to connect to the Internet (same issue occurred)
    Using a new Ethernet cord (I've used about three now).
    Got a new router (was free, anyway)
    Updated to latest Firmware on router (which is about two weeks old from Verizon).
    Tried a static IP (taken from IP Config)
    Tried Google DNS and Free DNS

    There are probably a few more things in there I've tried but forgot. But, that is generally where I am now. I bought a new NIC yesterday, which I will mess with when it arrives later this week. I doubt that will do anything, though.

    Here is an exerpt from one of the errors I receive in Event Viewer during a drop (usually it just tells me "www.so-and-so.com could not be loaded"): Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x6C626D57A3F4. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

    Any more things I can try? I am absolutely desperate at this point. I am posting my ipconfig during a lost connection below. I recorded it while in Safe Mode with Networking.

    would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
    Make sure you also indicate on the reply which tests 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 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.

    If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
    Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the infomation above those entries

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

    For windows version, XP, Vista, W7
    Hold the Windows key and press R

    Now type CMD

    Now 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.
