OK heres my situation. I recently have been using a linksys router with dd-wrt firmware on tit to connect my xbox 360 and laptop to my wireless network. It was working fine, but now my router that was sending out my network signal is dead. So I am currently using internet sharing with from my pc to my macbook. It works fine if I only needed one device connected to it. Is it possible for a router with dd-wrt to get the ad hoc signal from my pc and than be able to connect a few devices to the dd-wrt router? I know it has an ad hoc setting of some sort, but how can i set it up.
I'm a little unclear as to what your current network setup is. Are/were you using separate routers for your internet connection and your home network?
