Hello, I am having some trouble setting up Internet Connection Sharing. Here is my setup. My internet is through a neighbor who is sharing there internet with me wirelessly, so I don't have any type of broadband modem, just a wireless card on my desktop PC. I have a linksys WRT54G router connected to the desktop PC and tried following the guidelines for home networking, and works fine, but no internet connection now. When I unhook my router then my internet connection comes back. Its as if the computer is looking for internet on my network, and I dont know how to have it use the wireless internet from my neighbor and the network just for file/printer sharing. I have a laptop and a Wii in another room that the wireless isn't strong enough to reach. I thought I could use Internet Connection Sharing on the desktop in the room where it works to share that computer's internet connection over the router to the Wii and the laptop and basically "rebroadcast" the internet through my desktop PC's connection. I can't seem to figure this out because each time I hook my router back up, it just kills the wireless internet again. Also, my neighbor's router is on 192.168.1.1 - so I went into the router I have and changed it to 192.168.2.1 thinking this was the problem. When I reconnect my wireless connection to the internet and type in 192.168.2.1 it finds nothing. but 192.168.1.1 finds my neighbor's router. When I go into connections and click to disconnect the wireless connection it goes back to my router and 192.168.2.1 works again.

Is it possible to use my desktop's internet connection to rebroadcast to my wii and my laptop through my linksys router? If not, is there a way to use my wireless router for file/printer sharing with the 2 PCs, but still let them find there own wireless internet connection without looking to my network for it? Please help, thank you.

Ok, yikes, this can get pretty messy.. but here goes...
First, ICS (oe Internet Connection Sharing) requires sets you 2nd NIC to a default 192.168.0.1 address, this can not be changed for ICS to function.
So with that in mind , you are going to have to play around the 2nd NIC (network card) to get this up and running.

First you have to setup the router from being plugged in one of the access ports to login to router to make your settings. (hmm.. lets try to put this as simple as possible)


Main machine must have 2 NIC (network cards)
IF your Wifi card is getting from your neighbor, I assume 192.168.1.1 which is the gateway, means you should have somehting like 192.168.1.5 or something as you IP.
Your wired NIC should go to your router.. DO not setup sharing on the WIFI card just yet..
Login to your router, make your settings somthing very broad in terms of IP setting...Hell drop it to something like 192.168.6.666 or something, keep it as far as you can from 192.168.0.1 or 192.168.1.1 as possible.

make sure this is giving ip to the rest of your gear....


Now comes the decision part.. you decide if you want to let the router use DHCP or not, if you, you are going to have speed and redundacy issues on anything connected to that router, as the once ICS is enabled, it is fact acting as a router with DCHP also..not to mention the DHCP turned on your neighbors router...messy messy messy...


I would recommend that you turn off DHCP in your router as the last step of your router configuration, then reboot router..


Now go back and turn on ICS (internet connection sharing) on your WIFI card... This will set your 2nd NIC to 192.168.0.1 and turn on the dhcp...


From this moment, plug your wired 2nd card into the router, (now depending on your router model there is 2 ways you are going to have to try this)
First try to plug into one of the numbered ports 1-2-3-4 etc and reboot, see if you can now access Internet passthrough through router..


This should be getting up and running, if not then you may need to go an advanced setup using same setup but with a 10/100 hub added into the picture (not another router, must be hub)

and that takes alot more setup and configuration...
Just let me know if the firat way works..
