What is the internet interface equipment?
Assuming there's a router, is the router in the same IP address range as the computers?
If not, the router would be acting as a switch (only) for the LAN and nothing else.
If DHCP is being used then this wouldn't be a problem.
Is DNS working?
A good test for DNS is to do this:
Start / Run / cmd<Enter>
an IP address should come back even if no ping responses do.
No IP address returned, no DNS working.
Check the router/modem for DNS entries being proper.

We have DSL modem with wireless router build in. The DHCP is working since the PC has a valid IP address. I could not ping anything outside the LAN from this PC. But other PCs(three of them) have no problem to access the internet.

What are the local IP settings?  I would make sure that your default gateway and DNS are the same as the other computers on your network.

Could be a number of things, but need info from your computer and another computer on the network to troubleshoot it further.

Do you have a link light on the card and router for the ethernet that's getting plugged in?

To find out your ip info and give it to us:

1) Type CMD at the the run prompt
2) Type in ipconfig /all
3) Give us the IP info

Firstly chcek the cat5-e cbale using UTP tester so its working properly or notor change the router port  then update / reinstall the network card driver software then configure the IP address/subnet mask/Gateway and DNS address from ISP .
And also configure the workgroup or domain network configuration.
Check Norton Internet security / Zone Alarm/Mcaffe antivirus with firewall installed on your pc ...if yes then for testing uninstall or configure the firewall wizard menas trusted Ip range on your network. Uninstalled the wirless network card from the pc...?

yes, as kadadi_v says - the gateway IP should be the address of your router

to change it on a single PC, click on advanced on the page where it says you are obtaining the IP automatically. the page that opens will have 'default gateways' halfway down the window - click add and you're good to go. to change it on a rnage of IP's you will need to configure DHCP on the server
