My computer is currently connected with a cable directly to a WRT54G using DSL. I have an iMac in a second room with no wireless card or anything. I was going to buy a ethernet bridge to connect but they are a little more than I want to spend for the older iMac. A friend has an extra WRT54G that he's willing to sell to me for $20. Am I able to rig it up to where I hook the second WRT54G to the iMac and have it connect in to my WRT54G, sharing the connection? Thanks!
