    ISP: RCN
    Type: Cable
    Security: None, had Microsoft Security Essentials running but uninstalled that to see if it was causing an error. Basic Windows Firewall is enabled (although have tested without)

    The problem I'm having is the internet on my HP Pavilion Elite HPE-580t PC will drop for these short 10-30 second bursts. After the drop it will automatically start working again. This happens with all programs I'm running on the computer. The odd thing is that it's in a way random. Sometimes I won't get these drops for 30 minutes but then I'll get them every couple minutes.

    I've been trying to pinpoint the problem but haven't come up with anything. I tried plugging the computer directly into the cable modem and still had a problem (which I assume ruled out the router as a problem). It also would seem to rule out this being strictly a wireless issue. I removed antivirus (Microsoft Security Essentials) and have tweaked with turning off the firewall completely. I've tweaked the power saving settings to make sure the adapters are not turning off. Even went as far as blanking the hard drive and re-installing the factory settings.

    It's worth noting that I have no problems with other devices online. I have a laptop (uses XP) that uses both wireless and a direct connection to the router without issues. An iPad and Xbox 360 has had no drops when in use. This issue only happens with the desktop. The only difference in this device is it uses Windows 7.

    So I'm at a loss here. It doesn't appear to be the ISP (unless there is something they would do to cause issues with Windows 7) and the issue happens regardless of the router being used or not. It doesn't appear to be the wireless card since it still had issues plugged in. So I feel like it has to be either some setting on Windows 7 or some other hardware issue (Motherboard?). Everything else is useable on the computer, it just has these random drops that are driving me nuts.

    from the info above sounds like an issue with the desktop

    first thing i would do is use google open DNS on the desktop PC
    link below on the info and how to configure

    to test that you could try the ping tests below - but as it is disconnected for such a short time that maynot be possible

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

    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

    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

    Start> Run {search bar in Vista}> 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

    Also should note I just had a short drop after changing the DNS, so the problem continues.

    Thanks TerryNet for helping. I already have done that a couple times. Just did it again and don't seem to have any success.

    Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector and show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    Thank you for your time on this. For the record, I have messed around with the channel settings over the past week to no avail. And I also have this problem when it's directly connected to the cable modem.

    I don't see any clues there (it was a long shot anyhow), and I cannot think of what may be causing your issues.

    You might try running the 'CPU Meter' gadget. If the CPU spikes when the internet hiccups then use Task Manager to see what task may be a culprit.

    You might also try running in Safe Mode with Networking. If no problems there it's probably something running in normal mode. EDIT: Or a conflict with a device whose driver does not get loaded in Safe Mode. Or a conflict with the normal Display driver (which is not loaded in Safe Mode).

    If no problem there I suspect something deep in Windows or else a hardware problem.
