Can I use an AppleTV when I travel off my home network? I have a first generation AppleTV and I am wondering if I take it on vacation and connect to an HDTV with an HDMI cable, will it enable me to pickup programming off the WiFi in my vacation are for viewing?
You may have an issue with the hotel wifi. Oftentimes hotel wifi networks require you to open a web browser to login and use the internet. The Apple TV doesn't have a web browser so you might not be able to login and use their wifi network


@The Disco Spider

Heres my WAY OVER complicated explanation to solve the issue of Hotel/Plane WiFi requiring you to use a Web Browser to login on a device that does not allow this type of authentication

Some Info


Most (All) Hotel WiFi networks that require you to login on a webpage by either agreeing to TOS, inputing your room number and last name, etc. authenticate using a MAC Address
It remembers that you were logged in by using a MAC address so if you leave for the day (disconnect) and come back later (reconnect) you do not have to login
MAC Addresses can be easily spoofed, allowing us to authenticate with the same MAC Address on a compatible device
This method could also be used to steal paid WiFi, so take the moral route and don't STEAL`


Get MAC Address of the Apple TV (or other device)


Settings -> General -> About -> WiFi Address


Get WiFi interface and MAC Address (on your Mac)


Hold Down Option key
Click on the WiFi Button in the Menu Bar
Write down the Address
Remember the Interface Name (either en0 or en1)


Note: Disconnect the Apple TV/Device

Begin the Hack


sudo ifconfig [INTERFACE NAME] ether [APPLE TV/DEVICE MAC ADDRESS] //Spoofs MAC address to Apple TV's MAC address
Turn off WiFi and turn WiFi back on
If a webpage does not open, open Safari and navigate to captive.apple.com to force the sign in page
After logging in, once more navigate to captive.apple.com if you receive a Success then you are good to go
sudo ifconfig [INTERFACE NAME] ether [ORIGINAL Mac's MAC ADDRESS] \ Put back MAC address or you will have EXTREME connectivity issues
Turn off WiFI and turn WiFi back on
Turn WiFI on, on your Apple TV/Device


This should work as I have tested with an Apple TV, PS4, and many other devices.

Note: This may not work in WPA3
