Backstory: My bedroom gets really ****** wifi reception. We've had AT&T come out and they don't know why... blah blah blah, that stuff doesn't matter. Wifi sucks, but for some reason my macbook seems to get better connection than my iphone and ipad. So I'd like to somehow use it to piggyback off my router and create a second, hopefully stronger access point. Is this possible? I know you can turn an ethernet connected computer into a wireless router, but not sure about a wifi connected one. And no, I have no ethernet jacks in my room to connect macbook via that.
