Problematic Internet Connection

By foreverdizzy

  1. I'm having a similar problem, and would love to have some help. I know this post is rather old, but hopefully someone can help. I currently have a pretty old desktop, but it's been good to me up until now. I have a compaq presario model 5102US.

    My internet connection is always fine, and yet I cannot get to any websites, always showing the "page cannot be displayed" sign. After I restart, everything will by fine for a little while, about 5-10 minutes or so, and then the problem returns.

    At first, I ran an adaware scan and a Norton scan (both are up to date). When that didn't work, I went as far as reformatting my whole computer. And still, no results. Then, I figured it may have been my network card, so I bought a new one. Still, nothing. If anyone could help, that would be great.

    Hi foreverdizzy and welcome to techspot. =)

    Your post has now been moved to its own thread.
    Have you checked with your ISP with regards to this problem? How about your modem?

    Regards,
    Your friendly momok =)

    Hi! Thanks for the lovely welcome =)
    I don't think it's the modem because every other computer in my house seem to be working fine, and when I hook up the internet to my laptop, again, it seems to be working fine. It's just my desktop itself that keeps having trouble accessing the web.

    use the system until your browser fails; then
    get a command prompt
    enter ipconfig /all >myip.txt
    attach myip.txt to the follow-up post

    also enter nslookup www.google.com >mylookup.txt
    and attach it as well

    (both with be in your Documents folder)

    from this we can tell if it's your network vs. your browser

    ok; your TCP/IP settings are just fine so your system settings are correct.

    However, you are suffering from a DNS request timed out, which is
    not under your control.

    I need the DNS address as seen in your router config.

    Use your browser and access http://192.168.1.1/
    login
    and record the
    Gateway address and the two DNS addresses

    you can paste them into your follow-up.

    your last DHCP lease shows:
    Lease Obtained. . . . . . . . . . : Sunday, June 17, 2007 5:29:39 AM
    Lease Expires . . . .. . . . . . . : Sunday, June 17, 2007 11:49:27 PM​
    so your router will be dealing with this every day.

    be sure you have the latest firmware for your make/model.

    Sorry if this is a stupid question, but when accessed the given link and was requested the login information, I have no idea what my login information is or where it's from. Do I need to call my comcast provider to get it?

    you're accessing the Router, not the modem, so Comcast is not involved.

    Each manufacturer has a different default ip-address, admin-id and password so,
    state your router make and model number -- hopefully it is still defaulted.

    Thanks for the clarification, I found the information that I was looking for =)

    The two DNS addresses:
    68.87.73.242
    68.87.71.226

    The gateway address:
    68.34.16.1

    my,
    24 110 ms 109 ms 107 ms te-9-3-ur01.rockville.md.bad.comcast.net [68.86.252.201]
    25 106 ms 106 ms 104 ms c-68-34-16-1.hsd1.md.comcast.net [68.34.16.1]​
    these names do not instill any confidence!

    the attachments are BAT files you can use to test connectivity when your
    browser fails;
    run->cmd /k->$scriptX.bat

    save all three in your profile directory; mine is
    \Documents and Settings\Jeff

    and rename each by removing the trailing .TXT

    pinggateway.bat shows you can reach your IPS
    and the other two will show if your DNS is accessible.

    NOTE: If you'r browser fails AND the pingdns* fails, then ALL your systems
    will also fail.

    when I ran the command, it said that it "is not an internal or external command, operable program or batch file."

    does this mean I entered it in wrong?
