Lost Internet

Using my Dim 3000 and XP Home I suddenly lost network connection via cable modem.  My laptop work so I know the cable hookup is in tact.  This happened out of the blue.  Any thoughts are welcome.  Thank you all.

    SPAT61:

    Ok, you have two systems running off a cable internet connection. Do both systems connect to the cable modem, are you using a router, or what is your network setup? The more detail you can provide, model numbers, etc., the better.

    Hello Osprey,
    I don't use a router at all.  I'm straight from the cable modem to pc.  I only used my work Laptop to test the cable because the cable Co. techie said his signal was full strength using his test method.  A ping I think.
     
    I plug the RJ-45 into the Laptop and all is well, then unplug and plug into DIM3000, all I get is "cannot find displayed page" and no e-mail in or out.  I also bought a new cable with no difference.  Could I have lost a device in the control panel area.  In Device
    Manager I see 3Com3C920 Integrated and there are no yellow high lights. 
     
    System works fine other than loss of internet.
     
    Thanks.

    Well first of all, a router would allow both computers to use the internet and share files and a printer, so you might consider getting one. Without wireless, they run about $40-50, with wireless, a few dollars more.

    Ok, back to your Dim 3000. Here's how to see the details of your internet connection. Right click My Network places and select properties, then right click Local area connection and select properties. You should see the Local area connection properties window. Click Internet protocol and then the properties button. There are some options. Yours should be set to Obtain an IP address automatically.

    Hi Osprey,
    I did check the IP address block and it's checked to obtain an IP address automatically.
    Is it possible that my system came under a denial of service attack or some other virus?
    I'm using AVG.  Thanks

    We'll cross that road when we come to it.

    I would shut down your computer, shut off the modem, wait a minute, fire up the modem, wait for a signal lock, then start up the computer.

    The other benefit of a router is that it serves as a hardware firewall to prevent nepharious activity.

    I've come across this problem on numerous occasions.  Osprey's suggestion will resolve it temporarily, and the solution is to purchase a router.  Like Osprey mentioned, a router is acts as a firewall, allows you to share network resources, and acts as a DHCP server, allowing multiple PCs to connect simultaneously through one cable modem.  Any time someone has more than 1 PC, I recommend a router.  It saves the hassle of what you're currently going through.
