use my ubuntu laptop as a "router"

Tweet

hi everyone! I don't have a router at home, and my ubuntu laptop is wired to the internet. Sometimes my girlfriend want to use internet on her own laptop, so she steals the cable from my computer and puts it into her own. that's kinda annoying the two laptops have both wired and wireless lan. one solution could be to share the internet connection through my laptop via the wireless card. something like this: internet (wired) -- my laptop -- internet (wireless) -- gf's laptop. Is this possible? I have read this thread, but couldn't find out if it works with wireless sharing.. thanks
