Heres the deal, at home on the first floor I have an existing wireless network using a Netgear ADSL router - DG834G connected directly through NIC to a PC. The network also has two laptops that connect to it throughout the house wirelessly, I have the final computer upstairs and wanted to access the internet via crossover cable from this PC connecting to one of the laptops.
I have proceeded to try this by configuring the TCP/IP settings on both PC and laptop NIC's and have managed to ping each way, however i don't know how to configure this connection so that i am able to have file sharing capabilities and full internet access through this laptop!
If anyone could help me in any way?? namely a step by step tutorial!?!!!!
ICS might work but it's a clumsy, clunky way of doing what you want. No need to add another layer of routing. You want to bridge the two network interfaces. Remove ALL TCP/IP settings you've for some reason updated. Then go to network places properties where both LAN connections are showing, wireless and wired, highlight them both, and then right click for a menu. On that menu you'll see bridge network, or something to that affect. Click it and follow the prompts.
