Connect ATV to MBP

[cclloyd]

I'm going on vacation and I'm not sure how good the wifi at the hotel is. Is it possible to connect the ATV to my MBP for Airplay (no need to stream from ituens, netflix, etc.) just airplay from my MBP, a few iDevices, and a Toshiba.

I am not sure if this is possible, my option, would be to buy a cheap wireless router, and just setup a secure access point for your devices to use to stream to each other.

I think it should be as simple as going into the wifi menu and clicking 'Create Network...'

Copy Paste from the help center:

Create a computer-to-computer network
You can create a wireless network between two or more Wi-Fi-enabled computers without using an AirPort Base Station. Using what is known as a “computer-to-computer” network, you can share files or play your favorite multiplayer network game over the airwaves.

Computer-to-computer networks are sometimes referred to as ad-hoc networks.

Choose Create Network from the Wi-Fi status icon in the menu bar.
If the icon isn’t in the menu bar, choose Apple menu > System Preferences, and then click Network. Click Wi-Fi and select the “Show Wi-Fi status in menu bar” checkbox.

Give the network a name, and select a channel from the pop-up menu. The default channel is 11, but you can choose a different channel.
Select the Require Password checkbox to protect your network with a password. Type the password users will need to enter in order to join your network. Do the following:
Type a password of exactly 5 ASCII characters or 10 hexadecimal digits if you chose “40-bit WEP (more compatible)” from the Security pop-up menu.

Type a password of exactly 13 ASCII characters or 26 hexadecimal digits if you chose “128-bit WEP” from the Security pop-up menu.

Other Wi-Fi-enabled computers within range can join the network you created by choosing it from their Wi-Fi status icon or by choosing it from the Network Name pop-up menu in the Wi-Fi pane of Network preferences.

Computer-to-computer networks are not compatible with WPA or WPA2 protected networks.

Not 100% sure this works with appleTV but I see no reason why it wouldn't.
