Hi,

Is it connected to a router that is on and working? Have you tried connecting with another network cable?

    1. start the troubleshooting process by making sure that everything (routers,
      switches, hubs, modems, and computers) is firmly
      plugged in.

    2. If your computer is on and the other end of the Ethernet cable is
      connected to a network device, the link or activity LED should light.
      If the light remains dark after you plug in the cable, replace the
      cable. If replacing the cable gives the same result (no green light), then go to the next step.

    3. Once you’ve eliminated cabling as a source of the problem, it’s time to
      look to your computer. Start by making sure that your computer is able to
      access your Ethernet card. A good tool for doing this, and subsequent
      network troubleshooting, is the command prompt.

    4. Select Start, All Programs, Accessories, and then Command Prompt. When the Command Prompt window opens, type ipconfig –all
      and press ENTER. Various lines of information will display, depending
      on how your system is configured. Look for a section labeled Ethernet
      Adapter Local Area Connection. This section should include a line
      labeled Description, which should be a description of your Ethernet
      card. If you see it, then your computer knows about your Ethernet card
      and has successfully loaded the necessary drivers. If the Description
      line is blank or missing, you will need to reinstall the drivers for
      your Ethernet card.

    5. Your Ethernet card doesn’t detect a connection to the Ethernet cable. Open a command prompt, type ipconfig –all,
      and press ENTER. If the section that starts with Ethernet adapter Local
      Area Connection contains a line labeled Media, with a status of Media
      Disconnected, then your computer is unable to detect that a link has
      been made from your Ethernet card through the Ethernet cable to another
      network device, such as your computer or router. Recheck the cabling.
      Use a known good cable to connect your computer to a known good network
      device and then perform the check again. If the status is still Media
      Disconnected, and you are sure that the cable and the network device
      the cable connects to are good, then you may have a bad Ethernet card.
      Reinstall the Ethernet card. If the problem continues, you may need to
      replace the card.

    6. Other things to check:

    7. Bad connection, bad cable, or wrong cable. The ports on a
      router, hub, switch, wireless access point, and print server can, like
      any other device, go bad. However, the most common problem is not a bad
      port but a bad or loose connection, a bad Ethernet cable, or the wrong
      type of cable. Refer to the Cabling section above, to eliminate these
      possibilities.

    8. Wrong port. One possible cause of Ethernet port problems is
      using the wrong port on a network device. For example, routers have WAN
      (wide-area network) and LAN ports. These ports accept the same Ethernet
      cabling but are not interchangeable. The same is true of hubs and
      switches that have uplink ports, which are specially wired LAN ports
      that allow easy cascading of multiple hubs and switches. In some cases,
      the uplink port is also a normal LAN port controlled by a switch on the
      device. If you’re using the uplink port as a normal LAN port, make sure
      the device is configured properly for this type of use.

      If a
      port doesn’t appear to be working, you can use the link light to
      confirm it. Port link lights should always be lit when a good cable is
      connected between the port and another working network device. If you
      use known good cable and a known good network device to test the port
      but the link light isn’t lit, you may have a bad port. You can either
      replace the network device, or in the case of a hub/switch, add a hub
      or switch to gain more LAN ports.

    9. You cannot connect to other computers or router/Internet. When
      other computers in your LAN can connect to each other, as well as to
      the Internet or other services, and your computer cannot, this may be
      an indication that your computer did not receive an IP (Internet
      Protocol) assignment when you booted.

    10. Open a command prompt, type ipconfig –all, and press ENTER. In
      the section labeled Ethernet adapter Local Area Connection, look for
      the line labeled IP. If it starts with 169, you have a self-assigned
      IP, which indicates that your computer was not able to acquire an IP
      assignment from the DHCP (Dynamic Host Configuration Protocol) server.

      Test your access to the DHCP server by using the ping command. Open a command prompt and type ping
      followed by the IP address of the DHCP server. Your DHCP server is
      probably the same as your router. For example, if your router’s IP is
      192.168.1.1, then type ping 192.168.1.1 and press ENTER. You
      should see four lines of text, starting with Reply From 192.168.1.1:
      Bytes 32, followed by time values that indicate how much time elapsed
      between the ping command and the router’s response. If you see four
      lines that say Request Timed Out, then your computer cannot reach your
      router/DHCP server.

      Make sure the router is plugged in,
      turned on, and properly configured to provide DHCP services.
    These are just a few things to try to help figure out if it is your cable, ethernet card, router, or some other problem.

INET light is on not able to connect to internet


Checked the instruction manual online. There's no INET light indicated. There's Power, Status, WAN, WLAN, and LAN LEDs. The WAN LED only indicates that the WAN port is connected to another device, e.g., cable or DSL modem. Check on your cable or DSL modem to see if the Internet light is on. If so, then you'll need to log into your router and go through the configuration/setup per the manual for your type of connection.

Adsl wont stay on ,quick set up ,says cant find modem


Either the router is not connected properly to the modem, or the modem is not set up properly. First, unplug the router from the modem and disconnect power to both of them. Make sure the modem is connected to its data source, in this case the telephone line. Make sure the company has authorized the modem and make sure it's connected to the phone socket they specified, if they did. You should plug a CAT-5(ethernet) cable between the LAN port on the modem and the WAN port on the router. Now power on the modem. Wait until the modem's lights indicate it has a connection. If the modem doesn't indicate a connection, call your ISP. It will probably be as simple as them sending a refresh signal to it. After the modem finds a connection, power on the router. Your internet service should now be working. If not, try plugging the computer's network cable directly into the LAN port on the modem. If that computer then has internet, your problem is with the router. If the computer still doesn't have internet, then the problem is either with the settings on the computer or there's still a problem with the modem/ISP

My hp lap top wont connect to the internet through the usb the ethernet or wireless and it was working fine until 24 hours ago. I think it may be the network adapter. I re installed the driver for it but...


Try turning off the wireless router fo 30 secs and then power it up again. When the LEDs light up, then boot up the HP laptop.
If this doesn't work, then check the laptop to see if the wireless router issued the HP laptop with an IP address. to do this - click on Start - Run - type cmd and press Enter. This will open a DOS command box, then type ipconfig and press Enter.
If the IP address returns 0.0.0.0 then the wireless router didn't issue the HP with an IP address and either the wireless router is faulty or the wireless card is faulty or it has lost its LAN configuration.
If the wireless router LEDs are all on, try connecting a LAN cable direct to the LAN port on the router and the laptop to see if it connects to the Internet. If it connects then install the latest wireless card driver and configure it with the wireless router's settings.

My dell lan card is not working,i cannot connect to internet.


Either the LAN card is faulty or the LAN driver is not installed and/or not configured properly or the LAN cable is faulty.
Check Device Manager to see if the LAN driver is installed, working and enabled. If not then re-install the LAN card driver.
If the LAN driver won't install or detect the LAN card then it maybe faulty and needs to be replaced.
Try a different LAN cable.
Is all the LEDs on in the modem?
Try rebooting the modem (power it off for 30 secs and power it up again).

How do I hook my wireless usb netopia chip in order to sign on the internet


You ned to contact an Internet Service Provider to determine if your USB wireless adapter is compatible with their service.
Read this info for an idea on how to connect to the Internet :-

There several ways to connect to the Internet.
1. You can use a cable or DSL modem and connect this modem to the laptop with a LAN cable.
2. You can use a wireless router with a cable or DSL modem and connect to the wireless router using a wireless card (a PCMCIA wireless card or the laptop may have a built-in wireless card). This wireless card can also be used in WiFi locations such as the airport, McDonalds and Starbucks etc.
3. You can use an USB G3 wireless adapter. This type of device uses the G3 mobile network and may not give you Internet coverage in some locations.
All these require an Internet Service Provider and the costs vary widely depending upon the various plans they offer. Check the ISP in your area and compare the plans and cost of their plans and pick the one that best suits your needs.

Lan card disabled


When u plug the ethernet CAT cable in the LAN card socket , so you see any light orange or green flashing on the LAN card itself.
If yes then right click on my computer >> properties >> Hardware >> device manager>> check in network adapters whether the LAN card is enabled or not
If NO the right click on it and enable it check whether it is able to receive any ip address


If u see no light at all
Then you might have to install a new LAN card on the system

2 Eth Cards one for Internet & one for LAN


First of all, I would really recommend you to buy a Cable/DSL router. It is quite cheap, usualy more secure, much easier to configure and troubleshoot. Also, it does not require to have one PC up and running all the time, hense saving energy. Do you know that a PC running 24/7 may cost between 60$ and 100$ in electricity annually? This is more than the cost of a basic router!

But, since your question is about sharing your Internet connection with a PC, here are some guidelines. I will assume here that you are using Windows XP.

On PC1:
1. Connect the modem to Eth0 in the PC. Do not connect anything in the USB port of the modem.
2. Make sure that the link lights are lit both side. If they are not, you may need a cross-over cable (this is usualy not the case)
3. Configure Eth0 to get IP address DNS automatically
4. Disable (uncheck) all protocols except TCP/IP on Eth0.
5. Run the Network Setup Wizard (Start > All Programs > Accessories > Communications > Network Setup Wizard) and follow the steps.

On PC2:
Simply run the Network Setup Wizard (Start > All Programs > Accessories > Communications > Network Setup Wizard) and follow the steps. Specify and you Internet connection is through a Home or LAN network.

That should do it.

Network adapter is working but still not getting good connection


Make sure the light on your cable modem that represents your connection to the computer (it might be marked LAN, Ethernet, or PC) is lit up and isn't flashing. The light will tell you if your network card is properly connected to the cable modem.

If the light isn't on, make sure you've connected the wire to the right port on the cable modem, and try restarting the cable modem by unplugging it, wait 30 seconds, and plug it back in.

If it still doesn't work after that, contact your Internet provider. Their technical support department can help you get it set up.
