I am not able to connect to the Internet with more than 1 computer at a time on my home netwrok (I have a PureData 16 port network device). In order to connect to the Internet with my laptop I need to unplug the modem and then re-plug it in and then I can access the Internet with my laptop (but at that point my desktop cannot connect to the Internet). My providers' help desk says it's a question of recognizing the MAC address and the problem is in the hub device.
The PureData 16 port is just a hub and does not perform any of the housekeeping functions you would need in order to create a home network and connect several computers to the Internet at the same time. The reason why your procedure works is because your service provider by default will only allow you to have one IP address. When you unplug your modem that forces the providers equipment to reconnect to your computer and reissue the IP address. The way to get your desktop and laptop to connect simultaneously is to go down to your local computer store and purchase a home router/firewall. I?ve seen some on sale for as little as $35 at times and are fairly easy to setup. Good luck and let us know how it goes.

Connecting the Devices Together
After confirming the Internet connection through the modem, connect the modem to the Internet port of the router; connect the computer to any of the four Ethernet ports at the back of the router. For instructions, click here.
Checking the Router's LEDs
After connecting the devices together, check the lights on the front panel of the router. Ensure that the Internet light, as well as numbered light corresponding to the Ethernet port where the computer is connected, is lit. For further instructions, click here.
Setting Up a Linksys Router for Cable Internet Connection
Access the router's web-based setup page. For instructions, click here.
NOTE: If you are using a Mac computer to access the router's web-based setup page, click here.
On the Setup tab, click the MAC Address Clone sub-tab.
Select Enabled then click Clone My PC's MAC.
Click Save Settings.
Click the Status tab.
Check the Internet IP Address. If the Internet IP Address has numbers, this means the router has been properly configured. You should now be able to access the Internet. If you're still unable to access the Internet, powercycle the modem, the router and then restart the computer.
NOTE: If the IP address is still 0.0.0.0, click IP Address Release then, click IP Address Renew. If this does not change the IP Address, powercycle the modem, the router and then restart the computer.
