The problem:
I have Desktop computer connected to my Motorola Cable modem by USB cable (I did not know how to set up the Ethernet connection, when I wanted to remove the USB driver and to set up the Ethernet connection with my modem, it did not want to work)... So, now I have also the Laptop computer (DELL Latitude D620) which I would like to connect to the Internet by sharing Internet connection? I have my Desktop computer equipped with one Ethernet card and running WinXP. The Laptop is also equipped with one Ethernet adapter. In addition, I have also an AT-FS708LE 8 port Fast Ethernet Switch (if it can be of help). Can anyone show me the procedure so I can make both of my 2 computers working on Internet?

Thanks in advance.

A small consumer NAT router between the Motorola modem and the LAN is the simplest, most reliable fix. As noted, a router handles DHCP, NAT and basic firewalling so both machines (and the AT‑FS708LE switch) see normal private addresses and the network is stable without turning the desktop into the gateway.

Before buying equipment, get the modem’s Ethernet path working so any router will attach cleanly. Check for a physical RJ45 port and link/activity LEDs on the modem and the PC NIC; remove the modem’s USB device/drivers from Windows so the modem isn’t locked to a USB session; power the modem down, plug an Ethernet cable straight to the desktop NIC (set to obtain an address), then power the modem back up and wait for it to re-sync. If there’s no link light, swap the cable and test the NIC on another network to rule out hardware failure.

The sharing methods described by and (host-based ICS or direct PC-to-PC) work as temporary workarounds but have drawbacks: the desktop becomes a single point of failure, firewalling is weaker, and maintenance is fiddly. A cheap router removes those problems and lets the unmanaged switch provide extra ports without special configuration.

One common snag is ISP/modem MAC binding: if the modem still hands out an address only to the old USB endpoint, either use the router’s MAC-clone feature or ask the ISP to re-provision the modem. If Ethernet still fails after trying the steps above, note the exact Motorola model and modem LED behavior before contacting the ISP or testing with a known-good router.

You required one more Ethernet card for in your desktop computer for sharing Internet connection.
connection:
1.First connect the cable between your desktop and Motorola cable modem.Check whether you are able to use internet on Desktop.
2.Now use another Ethernet card of desktop computer and connect cable between Ethernet card and your switch.Now go in properties of that Ethernet card.Select Advanced Tab and then click text box indicating internet sharing.
3.Now connect cable between your laptop and switch.

3.Now

You'd probably want to avoid IP address clashing. I would never connect a switch directly to a cable modem. I'd connect a router instead (the switch can come off the router if you want). The router is the best place to do the internet sharing.

You would only require one ethernet port per computer, each plugged into the router. The router is plugged into the cable modem.

Simples.

The easiest way would be to get your self a cross over cable. connecting the to computers together .... make sure in same workgroup and under network connections give the computer with the internet an ip address of and the other ..... on the computer with the internet usb modem .... open my computer,,,, my network places,,, view network connections ,,,, right click on modem and select properties,,,, click advanced ,,, then Internet connection sharing tick all boxes ... click ok and ok again... restart... connect from pc with internet ,,, then try internet from other... this bypasses the need for a router .... the cross over cable

Hope this helps
