Hi, I just wanted to know if this is possible. I have a computer with a wireless card that connects to wireless connection. Now I want that card to connect to another router that have a computer connected to it and share the connection between the 2 computers. Is it possible?

You didn't mention where the first wireless connection is. Either way, I don't think you're going to get one wireless NIC to connect to 2 connections at the same time. It's only going to pick up one IP address.

I would use the router to access the broadband connection. Then share that connection across any media you wish. I'd just get another nic and use a common proxy software. It isn't the normal way but maybe you can put 2 IP's in that nic. You might need a special proxy to as ICS may not like that at all. Normally you would need two nics but in terms on software it might allow multihomed nic to perform that. For the most part a wireless and wired connection are similar but you will find more complex ways are available for wired connections as it has been around for so long.

TCP/IP Networking works like this: Internet | Gateway | DHCP Server | Switch (optional) | Clients 1-N Your gateway is a dialup modem, DSL modem, or cable modem, doesn't matter. The DHCP server can be hardwired into a router or software in a host PC. The Switch is a device that routes packets to each client on the local area network based on the IP Address assigned by the DHCP Server. (If you only have one client you don't need the switch or the DHCP server; your ISP will assign your client PC an IP address and you're good to go.) For what you want, you should move your router up between your gateway and your clients. Instead of connecting to the gateway via WiFi directly on PC #1, move it over to a LAN port on the router and connect the router to the gateway. Then run the Networking Wizard on each client, tell it that "this PC connects to the Internet through a router", give each client the same Workgroup name, different Client names, and disable/configure their local firewalls (the router's will cover both of them) so they'll "see" each other on the local area network (LAN). From here you can enable file sharing or play network games or what have you. The key is that the DHCP server in the router is what creates a LAN. You can do the same thing by setting up Internet Connection Sharing (ICS) on one PC and connect the other PC to it via a cable or 2nd NIC but you'd have to drop the router from the configuration. ICS sets up a DHCP Server on the host PC that establishes the LAN. It's not as efficient as using a router and you should run a firewall on the host PC to protect your data if you do it this way, though.
