Re: Problem with my lan port
One end of the ethernet cable goes to the LAN port of your computer and the other end goes to a router's LAN port - both equipments LAN indicator should lit up even with no configuration. try another ethernet cable.
just to be sure that your ethernet card is working properly, click Start then Run and type-in "cmd" without the quotes and hit OK.
DOS box shows and type at the prompt "ping 127.0.0.1" without the quotes and hit the Enter key on your keyboard. you should get 4 sends and 4 replies - else, reseat the LAN card.

Re: Problem with my lan port
Did you check the cable that is it working fine???
and the other thing does your network connection shows that the local area is unplugged if it shows then it is definatly problem with the wire or Connector.

The LAN (wired network) connectivity speed/data rate depends upon the networking hardware (Laptop Ethernet Cards, Switch, Router etc.). To get 1Gbps connectivity you must have 1Gbps ethernet (LAN) card in the laptops. As Dell Latitude D620 has 1Gbps card, the problem could be with the switch or router, which may be having 100Mbps and 1Gbps ports, depending upon the equipment you are using and it is recommended that you check out the its full specification. If you connect laptop to 100Mbps port you can only get 100Mbps speed. To get full speed, it is required to have 1Gbps support at both ends.

Means you have on bord LAN .
No worry you can add new LAN card easily in PCI slot on motherbord.
For that you need to pur chase new LAN card from store it is very low cost.
Then fix it in PCI slot of motherbord then install driver of it from disk which comes with lan card.That's it.
That slot is actuall not accessable externaly. The open bay is for the AGP slot right next to it. Directly to the left of that slot you have a riser board the provides 2 additional horzontally mounted pci slots. You'll have to use one of these.
start the troubleshooting process by making sure that everything (routers,switches, hubs, modems, and computers) is firmlyplugged in.
If your computer is on and the other end of the Ethernet cable isconnected to a network device, the link or activity LED should light.If the light remains dark after you plug in the cable, replace thecable. If replacing the cable gives the same result (no green light), then go to the next step.
Once you’ve eliminated cabling as a source of the problem, it’s time tolook to your computer. Start by making sure that your computer is able toaccess your Ethernet card. A good tool for doing this, and subsequentnetwork troubleshooting, is the command prompt.
Select Start, All Programs, Accessories, and then Command Prompt. When the Command Prompt window opens, type ipconfig –alland press ENTER. Various lines of information will display, dependingon how your system is configured. Look for a section labeled EthernetAdapter Local Area Connection. This section should include a linelabeled Description, which should be a description of your Ethernetcard. If you see it, then your computer knows about your Ethernet cardand has successfully loaded the necessary drivers. If the Descriptionline is blank or missing, you will need to reinstall the drivers foryour Ethernet card.
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 LocalArea Connection contains a line labeled Media, with a status of MediaDisconnected, then your computer is unable to detect that a link hasbeen made from your Ethernet card through the Ethernet cable to anothernetwork device, such as your computer or router. Recheck the cabling.Use a known good cable to connect your computer to a known good networkdevice and then perform the check again. If the status is still MediaDisconnected, and you are sure that the cable and the network devicethe cable connects to are good, then you may have a bad Ethernet card.Reinstall the Ethernet card. If the problem continues, you may need toreplace the card.
Other things to check:
Bad connection, bad cable, or wrong cable. The ports on arouter, hub, switch, wireless access point, and print server can, likeany other device, go bad. However, the most common problem is not a badport but a bad or loose connection, a bad Ethernet cable, or the wrongtype of cable. Refer to the Cabling section above, to eliminate thesepossibilities.
Wrong port. One possible cause of Ethernet port problems isusing the wrong port on a network device. For example, routers have WAN(wide-area network) and LAN ports. These ports accept the same Ethernetcabling but are not interchangeable. The same is true of hubs andswitches that have uplink ports, which are specially wired LAN portsthat 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 thedevice. If you’re using the uplink port as a normal LAN port, make surethe device is configured properly for this type of use.
If aport doesn’t appear to be working, you can use the link light toconfirm it. Port link lights should always be lit when a good cable isconnected between the port and another working network device. If youuse known good cable and a known good network device to test the portbut the link light isn’t lit, you may have a bad port. You can eitherreplace the network device, or in the case of a hub/switch, add a hubor switch to gain more LAN ports.
You cannot connect to other computers or router/Internet. Whenother computers in your LAN can connect to each other, as well as tothe Internet or other services, and your computer cannot, this may bean indication that your computer did not receive an IP (InternetProtocol)assignment when you booted.
Open a command prompt, type ipconfig –all, and press ENTER. Inthe section labeled Ethernet adapter Local Area Connection, look forthe line labeled IP. If it starts with 169, you have a self-assignedIP, which indicates that your computer was not able to acquire an IPassignment 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 pingfollowed by the IP address of the DHCP server. Your DHCP server isprobably the same as your router. For example, if your router’s IP is192.168.1.1, then type ping 192.168.1.1 and press ENTER. Youshould see four lines of text, starting with Reply From 192.168.1.1:Bytes 32, followed by time values that indicate how much time elapsedbetween the ping command and the router’s response. If you see fourlines that say Request Timed Out, then your computer cannot reach yourrouter/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.
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
turn off monitor of, wireless, so that windows wireless zero is your adapter the installed adapter dose not work as good as windows.restart your computer. if you try another port always restart after plugging it in a new usb port. I had the same problem. also you might have to uninstall and reinstall. then down load the latest updates.
Assuming you initially set up the router using the wired lan adapter and lead, enabled DHCP in the settings.
First stand right next to your router; Dells wireless is a little tempremental, go to control panel and in there should be Dell wireless monitor, open this up refresh it and see if it finds any wireless networks, if so try to connect.
Dissable your wired network lan adapter.
Go to the properties of your wireless card and on the TCP/IP line click properties again and ensure that obtain an ip address automatically is selected, press ok and restart the pc.
