How to force iPhone to use LTE to browse with WiFi airplay enabled?

This actually IS possible because the phone *can* connect to two networks at once. What it doesn't do is use both for it's Internet connection, but that's ok because that's not necessary.

1. Connect to the WiFi network you wish to use, and view the Info for said network

2. Under DHCP, note all the values that were automatically provided.

3. Switch to Static setup, and manually enter the values above. LEAVE THE ROUTER BLANK.

iOS recognizes that it cannot use the WiFi connection to reach the Internet, so it switches to mobile data. The WiFi icon will not be displayed, but you WILL still be connected to the WiFi network as well, and be able to access any resources on the local LAN (WiFi or Wired into your router's switch ports.)

This is tested and confirmed and used in a real world scenario on a 5S with iOS7, but probably works with earlier phones and versions as well. Specifically, this was used in a situation where Philips Hue light control was required while still connected to LTE. It has not been tested with AirPlay over WiFi, but theoretically it should work with that too. I was able to browse the WiFi router's admin interface while connected to LTE.

Caveats:

1. Because you've set your IP manually, there is a risk of possible IP conflict with another device on your network. This is unlikely on a network that does not have devices coming and going at all, and can be avoided if you specifically choose an IP that is outside of your router's DHCP range (If your DHCP range is x.x.x.2 - x.x.x.50, use .51

2. If you do actually want to use your WiFi connection for an Internet connection, you will have to remember to manually switch the WiFi connection back to DHCP (or manually fill in the Router, but it's easier and faster to just switch back and forth.)

I'm attempting to apply this information for an AppleTV that I am installing in my Chevrolet Silverado. Although I do not intend on watching YouTube while I drive, my wife would like to AirPlay YouTube in order to watch and to listen to music videos during travel. (I have started an AppleTV in a Silverado photo album on Flickr to detail my journey.) I have an iPhone 6+ on iOS8.1 and my AppleTV is at 7.0.1. Before installing the hardware into my truck, I'm testing it inside the house with a television that has an HDMI input.

What I can and can't do so far:

• Can control AppleTV with iPhone using "Remote" App = Yes.
• Can AirPlay local video on iPhone 6+ to AppleTV = Yes.
• Can AirPlay local audio on iPhone 6+ to AppleTV = Yes.
• Can Mirror iPhone to TV = Yes.
• Can AirPlay YouTube from iPhone 6+ to AppleTV = No.

iPhone 6+ Wi-fi Settings:

Static

IP Address = 192.168.0.200

Subnet Mask = 255.255.0.0

Router = ""

DNS = ""

Search Domains = ""

Client ID = ""

Router Settings:

Firewall = Disabled

Wireless security protocol = Disabled

DHCP

Router Address: 192.168.0.254

Subnet Mask: 255.255.255.0

AppleTV:

Using these settings, when attempting to stream video from Youtube through the iPhone to the AppleTV, all the AppleTV does is display the waiting "spinner" and after a short time, this error message comes up, "An error occurred loading the content. Try again later." I can see the video from Youtube just fine on my iPhone, tho. The problem is attempting to stream it over to AppleTV.

Thanks for any insight!

No.

You could always airplay from a computer or tablet connected to your hotspot network. There are utilities available which allow this. Bridge your network from a computer using the hotspot connection. Essentially the iphone becomes the internet source but your wireless network functions like it always did. Just use a different device for airplaying to apple tv.

Thanks a lot Jeremy, that's great information! It solves my problem streaming music from iOS on a boat where the Airport Expresses that are the target of AirPlay are creating a non-internet-connected wifi network.

TThank you soooo much for this solution. Couldn't understand why I couldn't stream from my iPhone within my network without an Internet connection on the airport wifi network but with LTE. All I wanted was some Hulu after a long day and my cable internet has been down in my neighborhood. This is great!

i don't think this works any longer since IOS 8. I can mirror the screen fine, all games, settings, but ZERO video like youtube, netflix or amazon video. I think Apple blocked all videos, and if anything works, it must be only through the Apple TV unit.

Logged in to thank you for this.

I would like for you to understand how much I appreciate this. I've been trying to find a solution for wireless audio in my car. I've been reading online for months. I've tested a dozen Bluetooth devices and they all had deal breaking drawbacks. 1st was always audio quality. When audio quality was borderline acceptable, there was some other issue - wouldn't pair consistently, dropped connections etc. Worst was almost all of them seem to want to beat your eardrums with the fact that it was changing the volume or powering up or managed to make a connection - "BOODALADOOP BEEP BEEP HI YOURE CONNECTED" at full Freaking volume. So I finally discovered the Airport express had an audio out jack. Felt guilty at the prospect of paying $100 to essentially solve the first world problem of having to plug and unplug a 3.5mm cord every car trip. Finally found one for $60 new in box. Set it up. It worked...until whatever music I had buffered ran out and the phone tried to get dat from the wifi it was connected to. I was so close. And now surely I would google the problem and not find any kind of easy solution. YOUR SOLUTION WORKED THE FIRST TRY AND IT TOOK ME 5 SECONDS. I HAVE HALF A MIND TO FIND OUT WHERE YOU LIVE, TRAVEL THERE, AND GIVE YOU A BIG SLOPPY KISS WETHER YOU LIKE IT OR NOT.

I am just trying out T Mobile's 'Binge On' and wanted to stream content from my iPhone 6+ to Apple TV 4 while connected to LTE.

I Tried the technique of using a static IP so that I could connect to the Apple TV through the network but continue to stream through T Mobile's LTE but setting the IP and Subnet Mask manually and leaving other fields blank doesn't seem to be working. After a few seconds the phone displays the wifi symbol rather than LTE.

i Have used this method previously to connect to a wifi OBDll device while maintaining LTE. Any new technique for keeping the LTE connection while staying in the wifi network for AirPlay Mirrowing?

thanks

Actually, I believe a feature allowing this will be introduced in iOS 8, if I am not mistaken.

This can be found under the "Enterprise" section of iOS 8, under the "What's New" drop down.

If you are connected to wi-fi, that is all it will use. You cannot use LTE to browse and expect to use Wi-fi for the connection to Apple TV. The iPhone cannot connect to both at the same time.

I Have the same problem and am wondering if you found solution?

thanks in afavance for sharing it.

best

Apple does not block any of those the developer of the app does.

Dude this totally worked I can LTE and do airplay on wifi I love you right now lol

Thanks Jeremy Shaffner, worked beautifully.

Thought it wasn't possible (according to plenty of people out there), but is easy to set up and works
