my computer on LAN there are several pc , all have internet, but my pc internet not working Ans. in detail?

Answer 1

Without knowing the actual error message you're getting it's not possible to diagnose the fault.
Have you been able to get onto the internet in the past? If so, try a reboot.
Have you changed anything since you last used the internet? Put the changes back to how they were before.
Are you in a corporation that has discovered you're using the internet when you should be working and blocked your access?

Answer 2

Need more info. What operting system? What type of LAN, peer to peer or client-server? If server-based, what server OS? And where's your net admin?

Try these steps...

1. Swap out the network cable with one you know works.

2. Start > Run, type in 'Ping 127.0.0.1'. Hit . This is the loopback. If you don't get a return then either your network card or the router is at fault.

3. Try pinging the router IP -- on a P2P network, this is ususally 192.168.0.1. If you're on a client-server network, find the server IP address and ping it. Are you getting through? If not...

4. Bypass the router and connect your computer directly to the cable or DSL modem. Be sure to unplug the modem from its power and power off the computer first. Leave the modem off for at least a full minute before plugging it back in and wait for all the green lights to burn steadily. Power up the computer. Can you see the Internet now?

5. If you can't, you have a bad network card. Replace it.
If you CAN, return everything to the original network configuration. Shut everybody down. Remove the router from its power connection. Remove the modem from its power connection. Wait a full minute. Power up the modem as before. When it's finished negotiating, power up the router. Power up your computer. Can you get on now?

6. If you can't, there is a problem with the router. Try plugging into a different port. Reconfigure or replace it.
If you can, everybody else can power back up.

Some other steps to try if your user account on your computer is an administrator...
7. Start > (Settings, if necessary) > Control Panel > System > the Network Identification tab. Make sure your computer is on the same workgroup as the others on the network.

8. Back to Control Panel > Network Connections > Local Area Connection > Properties. Make sure that the proper client (...for Microsoft Networks, Family, etc.) are installed. Make sure the proper protocols are installed (IPX/SPX for Novell, TCP/IP, any others that are used on your network). Check the Properties for each and renew the connection if necessary.

5. If #4 doesn't work, try uninstalling and reinstalling each individual protocol.

If you're not logged in as administrator and can't log in as such, find the person who can. He/she's the one who should be fixing this.

Answer 3

Have you specified the correct IP Address of your gateway machine? If you don't specify that and check.

If you don't know the gateway IP address then you will get that from your network admin.

Or

You can go to one PC that has Internet connection. start->settings->Network Connections then select Local Area Connection icon, right click select properties.
click on Internet Protocol (TCP/IP) entry and click on properties.

Note down the Default Gateway IP address in your friend's computer and also the Preferred DNS Server IP Address. Go to your system access the same screen and setup the default gateway and DNS server IP address and check

Answer 4

You need to go to your browser tools optin and select connectivity then click the lan tab where you put your server address and port no. if you ip address was not restricted you should get connection.

Answer 5
