No, you cannot substitute a Cable modem for an ADSL modem or visa versa (a Cable router is just a router with a built in cable modem, as is the same respectively for an ADSL router). They are two completely different technologies (a Cable modem syncs with CMTS and an ADSL modem syncs with a DSLAM).

You also cannot use the WAN port on a modem/router combination as if it were a standard router as it is looking for a different type of signal (that from a CMTS or DSLAM depending on the type of modem, it is not an Ethernet protocol).

You will need to purchase an ordinary router to place in between the PC and the ISP provided device. You will also need to make sure that they are in different subnets (ie, the cable modem/router will be using DHCP/NAT with 192.168.0.1 as the gateway, your router will accept a lease on the WAN and hand out DHCP/NAT on the LAN with 192.168.1.1 as the gateway).

I have finally come up with the solution. It's simple really, as simple as anything! Internet Connection Sharing is the way to go. This is what I tried earlier, but it didn't work before due to some errors in the Router configuration.

• 4G Modem once connected will be shown in Network Connections as an Ethernet Adapter.
• The WAN port of the Router should be connected to the LAN port of the Computer.

1. Right click on the Adapter that is connected to the internet.
2. Select Properties.
3. Switch to the Sharing tab and check Allow other network users to connect through this computer's internet connection
4. Its important to make sure that the router is configured to "Obtain IP Address automatically." This can usually be done by connecting the router to a PC via a LAN port and using the web browser. The details should be in the routers manual.
