This happens if your laptop is unable to obtain an IP address from the cable modem. The cable modem automatically assigns an address to your laptop and it has a pre-set "expiration" period. \n\nThe problem could be with your modem or the service provider. \n\nYou could manually query for an IP address. If you have a Windows XP or 2000 machine, do this.\n\n1. Click on Start -> Run\n2. Type "cmd" (without the quotes) and click on OK.\n3. A black box should popup with a cursor blinking.\n4. Type "ipconfig /release" (again, without the quotes). You should get a message like "Successfully released the IP address" or something similar.\n5. Type "ipconfig /renew". If successful, you should get a display of what IP you have got and the little exclamation sign next to your LAN connection should be replaced with a balloon saying "Local Area Network is now Connected".\n\nHope this helps.

try contacting your ISP or internet service provider. there might be some problem with the lines that's why you are experiencing intermittent connection to the internet.

i think your modem or something has a problem\n\nor for example, if you have comcast internet, the comcast people might be having problems or something\n\njust try again later cause that is what i did, but you have to fully shut of your computer and modem first

if your dialup, disconnect and reconnect, if your cable, disconnect for a few days, more or less, or change your mac address would probably cause it to issue a new ip, if your dsl, not going to happen easily generally

Go to start, control panel, system, hardware and then device manager. Click on modem and see if it has a yellow spot on it.. that will tell you there is a problem, you might just need to download a good driver for it to work.

The problem could be both. Until we can test and be sure of what exactly is happening we can't be sure. \n\nThe best thing that you can do is call up the isp and talk to a technician. They have tools with which they can test your connection. If they say that the problem is with your computer, then have your computer checked by a professional.

Go to speedguide and use there tcp/ip analyzer/optimizer to see where the problems in your system are at

I had the same problem with my laptop. Comcast really sucks with their wireless things, my desktop and my brother's worked fine. But my laptop didn't. I actually ended up getting rid of my laptop when it broke because so many things were wrong with it and we believed it was caused by comcast's updates. Complain to comcast until they come to your house and fix it and see about getting a reduction on your bill for lack of service. \nEventually the connection won't connect at all. Don't waste money on getting a computer tech to come out, the odds are he's going to tell you it's comcast. And comcast is going to tell you it's your laptop. Insist that they give you a new modem. \nThere are probably more options, but I'm not great with computers so I avoid technical things like removing and adding hi-tech things, so I complain to my providers.\nHope that helped or gave you a new perspective.

Yes.\n\nIn addition to the post below, sometimes you may have to unplug the modem, disable network adapter, follow the instructions in the answer below, then turn off the computer for a while.

if built in, and it can't be salvaged, write it off, get a pcmcia card with a modem in it, re-configure which modem you use via software and keep truckin'

You can simply disconect the cable -- or if you're using Windows, go to Control Panel. If you're using XP, switch to classic view and go to Network Connections. Rightclick on the icon there [Local Area Connection if you have only one Network card] and select "Disable". That's all.

You might want to check your event viewer and see what is happening to your computer when it loses connection -\nControl panel..administrative tools..event viewer.\n\nLook at the logs and see any tcp/ip events.\n\nIf you see the connection being dropped randomly in the logs, it might be your wireless card or the drivers. try and uninstall the card completely, uninstall the drivers and then use the correct drivers- possibly from the manufacturers website.\n\nalso try and disable all security such as wep / wpa for your network and see if the problem occurs, if you still have a problem then its most possibly your wireless card drivers. Some wireless cards when the drivers are installed disable your wireless zero service and cause havoc. What kind of card are you using.. post it on here.

#1 - Take the router out of line. - If your problem persists, then you can eliminate the router as being bad.\n\n#2 - Make sure all of your cables are good. Just one bad cable can cause the intermittent scenario you are describing.\n\n#3 - Power cycle the modem. Turn off your computer first. Then, unplug the power cable from your modem for at least 30 seconds. Plug it back in and restart your computer. \n\n#4 - Check your Network Interface Card on your computer. \nStart \nControl Panel\nSystem\nHardware Tab\nDevice Manager\nNetwork Adapters\n\nRight click on listed adapters\nproperties\nDevice Status is? If this says your device is working properly, then this COULD eliminate this problem. Not 100% guarantee though.\n\nBorrow a friend's modem (if you can) and hook it up. This will help you determine if your modem is the culprit.\n\nStill no help?\n\nCall your service provider technical support and if you are nice, they may walk you through your problem at no charge. They will also inform you on how you can obtain a new modem, if that is the case.\n\nHope this all helps!

sometimes routers and modems "get stupid". Try unhooking the power and ethernet cables from the back of the modem and router if you have one. Wait 10-30 seconds then plug them back in. This is one way to RESET the modem and router. YOu might have to do this from time to time. Its nothing to worry about.

if you have a cable modem just turn it off count to 5 turn it on. most will reset when you do that.
