Reviving this thread because it is directly relevant to what I'm trying to do.
I moved a computer to another room, and now it can't be plugged into my router (Netgear WNR3500v2). The computer doesn't have a wireless NIC. I have a wireless NIC card on the way for it, but the card will not arrive for about a week.
In the meantime, I have a netbook which of course does have Wi-Fi as well as a wired Ethernet NIC (albeit only 100 Mbit).
Last night, I tried for 2 solid hours to share the netbook's Internet connection with my own Windows 7 desktop, to no avail. The most I could get was recognition that a connection existed, but Windows 7 kept saying "No Internet access" no matter what.
I tried pretty much everything mentioned in this thread, including:
-running Network Wizard on the XP netbook to share its Internet connection
-putting the wired connection between the Win 7 desktop and the Win XP netbook "home" mode (enabling network discovery)
-tried setting both connections to either automatically acquire an address, or manually setting an address. Neither worked.
I'm out of ideas here. Isn't there some way I can have the Windows 7 desktop access the Internet through the netbook's wired NIC?
I have both crossover and conventional Cat5 patch cables. The last time I did ICS, both machines were running Windows XP, and I didn't need the crossover cable. As I understand it, any reasonably-modern NIC can auto-negotiate the connections, so that crossover cables are no longer needed to connect one NIC to another.
Sharing files/folders between the Windows 7 desktop and other machines on my LAN would be nice, but is not required. The point is to get Internet access until the wireless NIC gets here.
