Question : Internet Connection Sharing Problem...

Hi friends !

I am facing a very serious and strange problem. You see, I am running an internet cafe and subscribed Wireless Broadband from ISP.

My ISP gave me one public IP address and so to distribute it among all internal 15 PCs, I installed second NIC and used "Internet Connection Sharing" on my Public NIC card.

Now, All client PCs are set to receive TCP/IP settings automatically as ICS needs this setting. I get internet connection successfully. But the serious problem is that:

The connection to server resets after sometime automatically and I don't get internet on my internal PCs. I receive the following screen that I have attached.

Then, I have to give "repair" command to repair the card on those internal PCs, and then I get internet and sometime even doing repair does not work. Then I have to uninstall the card and then install it back and then it works.

You see, this is a very bad situation when clients are doing internet and such problems occur.

When I ping to ISP gateway from my ICS Server, the ping is successful and so there is no problem from ISP end. The problem is internal.

For me, I am CCNA certified and have worked as an Network Administrator in an organization for more than 3 years. I configured Routers, Switches and so I can say that I have at least intermediate understand of how computer network works.

But, surprisingly, I am unable to solve this problem. Please help me to sort out this problem.

Regards.

Answer : Internet Connection Sharing Problem...

Dear Jatin Hemant!

It seems that the problem is with the setting of your LAN cards.

Specially the setting of lan card named 'allow the computer to turn off this device to save power'.

1- Just go to control panel
2- network connections
3- right click the LAN card and go to properties
4- Then click on Configure or something like that (depends on win version)
5- Then click 'Power Management'
6- Uncheck 'allow the computer to turn off this device to save power'

This will solve the problem, because to save power OS shut off the power of some devices based on configurations.

I hope this will solve the problem.

Best Rgeards and good Luck
