I just bought a Wireless Router that has 4 Ethernet LAN Ports and one WAN port. The manual that came along with the Router asks to connect a Broadband (Cable/xDSL) modem to the WAN port. However, I do NOT have a Broadband modem. I use a 4G USB modem to connect to the internet.

What I would like to do is share my Computers internet over the Wireless Router.

What I've tried so far:

  1. Opened "Network and Sharing Center" (I'm on Windows 8)
  2. There are two adapters listed. One is the Computers Eternet adapter (I connected it to the WAN port of the Router) and the other is the USB Internet.
  3. Right Clicked on the USB Internet adapter -> Properties -> Sharing -> (checked) Allow other network users to connect through this computer's Internet connection

Expected Result: I wanted to be able to connect my Samsung Tablet to the internet by using the Wireless Router. But it seems its not working. The router isn't routing Internet.

What am I doing wrong? I feel the solution is simple enough, but I am totally new to networking. This is my first attempt really.

Any help would be hugely appreciated.

EDIT: After I did a bridge between the two connections, I lost internet connectivity. The following screenshot might help

With the bridge in place, I connected another PC to the router via an Ethernet cable. On that computer, IP addresses shown on the Router configuration page ( seemed to be the right ones. However there was no internet connectivity on that computer as well.

Is the router set to get it's IP from your laptop (i.e. DHCP) or is it static? You should be able to check in the Router's Setup-pages. If this can even work (which it seems like it should), they would need to be on the same subnet. –  nerdwaller Oct 31 '12 at 18:58
I tried Automatic. If I try static, it gives me some forms to fill up. IP Address, Gateway, etc. –  Rakib Ansary Oct 31 '12 at 18:59
Looks like @SLaks got it for you, that makes sense. And yes, you want automatic so you are good there I think. –  nerdwaller Oct 31 '12 at 19:00

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.

enter image description here

  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.
