How to share LAN internet via wireless router

internetlanmodemnetwork-shares

I have internet signal in gray cord in below snapshoot. I can have wifi internet connection when plugging in the gray cord to port 1,2,3,4 and NOT to the internet port as shown in the snapshoot.

Currently I use blue cord to share internet to my PC. It works with one cord in any of the port 1,2, and 4. But when I plug in ANOTHER cord to use on the 2nd PC, the LAN connection show in that PC reads "Unidentified Network – No internet access"

What I am doing wrong? How can I share LAN internet for 2 PCs?

Best Answer

Your gray cable is plugged into your ISP router and that is where your "Internet" is coming from. Some ISP routers like the Motorola surfboard only hand out 1 IP address. That one address is getting assigned to the first pc on your network since you are using the other router as a switch. When you plug in a second cable there is no internet access because your first PC already has the one address your ISP router is willing to give out. To resolve this

  1. Plug your gray cable from your ISP router/modem into the internet port on your Dlink modem

  2. The deault IP for your model Dlink is 192.168.0.1 Open an internet browser and put in that IP address. The default username is "admin" and default password is blank.

  3. Setup your Dlink router. Link to some useful settings to use.

  4. Plug your blue cable and up to three other Ethernet cables into the remaining Lan ports. As long as you setup DHCP on your Dlink you will be able to connect multiple PC's to your internet.
