Computer not recognizing ethernet cable

For some reason all of a sudden my computer isn't recognizing that my ethernet cable is plugged in. The modem and router work fine, and tested the cable on another computer and it worked fine, so must be the computer, but can't figure out why it can't see that the cable is plugged in.

    I did the ipconfig/all and it couldn't find and IP address, it also said Media State Disconnected. It does show the icon on the bottom that says I am not connected, but I do have the cable plugged in.

    Can you not ping your router? Does the card show any lights? In a Command Prompt windows, does "ipconfig /all" show an IP for your computer? Try "netstat -rn" to show current connections.
    Do you mean you no longer see the little icon that shows you are connected? Go to Start -> Settings -> Network Settings -> Local Area Network (this may have a different number or name or may not even show one if it's not working). There's a checkbox on the Properties settings that shows the little icon in your active icons area (beside the clock). Also, you may have it hiding inactive icons (an arrow beside the clock that opens or closes to show more icons).

It's the card itself. It probably went bad. Go to Walmart and pick one up for about $15. I had this happen a few weeks ago, All cables are good just wouldn't connect to internet. It's the ethernet card itself, they do go bad.

I agree with bambi541 that it's probably the ethernet device. To replace it you need to determine if it's an add-on card or the built-in kind. It depends upon what type of box you have. If it's a tower, the CD and floppy drives are near the top and the power button is near the middle or lower down If it's a "pizza box", it lays flat on your desktop and you usually put your monitor on top of it. Looking at the back of the computer, if it's an add-on card, it'll be either on the bottom half of your computer or to the right, close to the keyboard and mouse connections. If it's built-in, you should disable it in the BIOS. If you don't know how, I'm pretty sure you can get by without disabling it, but it'll keep showing the "bad" icon as well as the new one. You might have to install some software with it, but XP is pretty smart with new stuff and may not need it. Just check the instructions. (You just need any 100MB ethernet card and it will be pretty cheap.)

Unplug both of them. Make sure one end of an Ethernet cable is plugged into the modem's Ethernet output port and the other end is plugged into the router's single WAN/Internet input port. Plug in the modem and wait for it to boot up and then plug in the router and see if it works.

The Cable modem must be disconnected from the computer. You cannot use USB and Ethernet at the same time.

1. Turn off power to the Cable Modem and the Netgear Router. Do the same with the computer.
2. Connect an ethernet cable from the modem to the router's WAN (Internet) port.
3. Connect another ethernet cable from one of the remaining 4 LAN ports on the router to the computer's ethernet port.

4. Now power on the Cable Modem ONLY. Wait for the modem to sync up with your service provider
5. After about 2-5 minutes power up the router and wait about 1-2 minutes.
6. Now power on your PC.

Check and see if you have internet access. If not you may have to uninstall any cable modem software related to USB connection. if this is the case, then you may have to repeat steps 4-6.

Since most cable internet providers do not use proprietary connection settings, your internet connection should be up and running without changing any settings in the router or modem.

If this does not resolve your issues, we can continue to work with you.

I try 2 plug my modem up 2 my ps3 but the ip address timed out wat do i do

After you have the Ethernet cable from your modem plugged into your PS3 press and hold the reset button on the back of the modem for about 5-10 seconds. This will reset the modem so that it will recognize the connect to your PS3. Once your done using your PS3 and reconnect the Ethernet cable back to your computer you will have to reset the modem again. Any time you move the Ethernet cable from one device to another you need to reset it after you have the cable connected to what ever device you want to get online with at that time. If you do not want to keep resetting your modem all the time a router will allow for you to have more then one device online at a time. The router will connect to your modem and then your devices will connect to your router.

Why my modem dsl isn't recognized by my computer

It does *NOT* need to be "recognized".

Connect a telephone-cable from the modem's telephone-port to a telephone wall-jack.

Connect the AC power to the modem.

Connect an Ethernet cable from the Ethernet-port on the modem to the Ethernet-port on your computer.

If you don't get an Internet connection, contact your ISP, and ask for Technical Support, and get them to trouble-shoot.

Connecting modem via ethernet cable

I'm not an expert in window based units but since it worked with Vista OS and not with XP. Sounds like you might try re-installing XP again. Take note on any windows that refer to the ethernet port during installation. It is likely you might of hit "next" without reading all the text. I know I have in the past. I changed over to mac and I know longer have any problems only at work but give then I give it to the IT Dept and wait and wait and wait.

Ethernet vs. usb

FYI for those people trying to use a ethernet and usb cable from a cable modem - it may work for a while but it won't work forever - your ISP will only allow one IP address out of the modem unless you pay for additional addresses (then you need a switch). Each device you have on the modem is fighting for that IP and eventually it will just quit working (if it works at all).

If you want more than one computer on your network (on the Internet or sharing printers/files, etc) then you need a router or a gateway (cable modem/router combo which I DON'T recommend).

Modem not working right

Do you have both an ethernet and a phone cable connected to either your modem or your computer? If you have an ethernet connection, there is no reason to keep the phone cable connected. They are competing. Remove the phone cable and you should be fine.
