I have a Iphone 4 and a wireless router. I'm on holidays and the only internet connection I have is via tethering my Iphone to my Macbook pro. I have successfully set up a network with my wireless router so that I can use my Apple TV in conjunction with my MacBook. Problem is; when I use the router with the ATV; I lose my internet connection as it appears the MacBook can only connect to one network at a time. My question is; is it even possible to do what I want it to do; connect to the internet and still be able to use my network setup???
