[Q] Use mobile data while connected to wifi - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

I would like to be able to stream netflix over 4G while connected to a wifi point that has no internet to stream to chromecast.This would allow me to watch netflix while traveling on the hotel TV using the Asus WL-330NUL ( I can't link it yet).
Alternatively if anyone knows how to adhoc connect with chromecast that would be cool (But this is the wrong forum for that)
I have googled both of these issues and searched the wifi issue on XDA so hopefully this isn't a repeat.
I am not rooted since I have JUMP and that would void it but I have rooted all my other phones.

Chromecast and Wifi Tether

I have been trying to get my chromecast to work correctly on a wifi network tethered from my GNex and I was hoping to gather info from others trying the same.
So far to get the chromecast to show up on my tethered network I had to set it up on a standard network first. Once it had updated to the latest version it then works on the tethered network. This means that I can see the chromcast from other devices on the tethered network.
What I am trying to achieve is to use my GNex as the wifi hotspot AND connect to the chromecast. With the newest update this has been working but only with Play Music. I have tried RemoteCast and that works but Netflix, and Youtube do not. Bubble uPNP does not recognize the chromecast either.
Anyone have similar/different experiences?
It seems like the issue is that the apps are not recognizing the chromecast's broadcast on a tethered (ip isolation) network.

I was using hotspot on my gs4 and everything worked fine. I think the gnex tether is booked because I still can't use it on a windows PC, only other android and iOS devices.

WiFi Network dependency

Hi,
Do I need a standalone WiFi network available to cast from my device to the TV or not?
Will I be able to go to friend and cast something from my tablet to his TV even thou he does not have WiFi at home?
Yes, you need a WiFi network and an Internet connection accessible from that.
If you just have your tablet and Chromecast, the Chromecast won't be able to find a network, as your tablet is not a WiFi access point.
I don't know of anyone who has tried setting up their phone/tablet as a WiFi hot spot and connecting Chromecast to that. I'm not certain how Android hotspot NATs and/or isolates clients.
Best to just bring a small wireless router. There are a number of "travel router" devices that have an internal battery or can be powered via USB.
Connect it to your friend's Internet connection, then off you go.
If the goal is just to show stuff from your tablet on your friend's TV, it might be easier/cheaper to just go hardwired with an HDMI or VGA output adapter for your tablet, if it has that option.

Remember that Chromecast still needs a connection to the Internet in order to negotiate the application launch.
Thus the Hotspot. Just might work.
My friend is technologically challenged
He's got no internet at home apart from out mobile phones which we can use for internet at his place...
So, can I use my phone's Wifi hotspot to and use my phone/tablet to stream the web to his TV?
How does the Chrome cast work? Is the tablet interphase only used to set up a link between the dongle and the wifi sender/ router?
For native apps, Chromecast works more like a your phone/tablet in the fact that it pulls the requested data and plays on its own. The video isn't going from the Internet to your phone/tablet, then from your phone/tablet to the Chromecast, your phone/tablet "hands off" the request to the Chromecast and the video goes directly from the Internet to the Chromecast. The control via tablet/phone is done through a "side" channel that Chromecast listens on, which also lets your phone/tablet know what Chromecast is doing.
For example, YouTube...
You open YouTube on your phone/tablet
You find a video
You cast it to your Chromecast
Chromecast "phones home" to Google to figure out how to handle the request (I think)
Google replies with "Use the YouTube app"
Chromecast runs its YouTube app to open the link and starts playing
While it's playing on, Chromecast sends its status to your phone/tablet and listens for control commands.
So... Using your phone's WiFi Hotspot for the Chromecast might (should?) work, and what'll happen is Chromecast will connect to your phone via WiFi, and your phone will connect to Internet via mobile network.
In this case the streaming performance will be limited by both your phone's mobile data speed as well as the WiFi connection speed/stability between your phone and the Chromecast.
While I don't necessarily think this will provide a good viewing experience, it's an interesting experiment.
If you have a rooted Chromecast with Kyocast, you should be able to use the un-timebombed AllCast/AirCast to stream video stored on your phone to the Chromecast. It'll still use mobile data to "phone home" (to the Kyocast server) to figure out how to deal with the request, which will launch the AllCast/AirCast magic. From there I believe the video data will stream directly from your phone to the Chromecast, not using your mobile data... I think.

Thanx so much for all this data. Not sure whether I wanna try the rooting now. Will wait to see what Google has in store in the next month. It's rooting the dongle easy? Rooting phones comes naturally by now...

It's really easy with Flashcast but if your Chromecast has been connected to the Internet for more than a few minutes then it has probably auto updated to a non-root able state.

I've been doing that for weeks now, if you access 3G (4G) from your device then set it as an access point, and connect to its network with CC. Then all you need is something else to connect to Netflix and the same WiFi access point (a tablet for example or another phone) and you can send it to CC.
The other device is necessary because the Netflix app doesn't show the CC share icon when connected to 3G, whereas on the other device because it's connected to 3G through a mobile WiFi access point it does.
You could use a MiFi instead.
I use it in hotels this way with the CC plugged into the hotel TV (if I'm lucky)

Streaming from phone that is also the Chromecast's hotspot/connection

So, at work I don't have internet, but I have my phone, and I have a chromecast on the tv. I use my phones hotspot all the time for my ipad and laptop with no problem. I have my chromecast setup on my Nexus 5's hotspot as it's internet connection. It works fine if I use my ipad to push content to the chromecast, but on the phone, all apps hide the chromecast option.
So basically the chromecast is invisible to the Nexus 5. I guess because the Nexus 5 is technically the Chromecast's router, and not a fellow client. There are a lot more apps that have chromecast support, so to get this working from my phone would be great. Is there a way?
I use my phone hotspot and play videos all the time. You can use video caster and chrome beta. I tried Netflix and Youtube but didn't have any luck.

I would think that putting the phone into tether mode changes the way the networking works and would prevent it from making direct outgoing connections to anything other than the Internet.
I could be dead wrong however.
The problem with Hotspot/tether is that the Chomecast can't see the phone because of AP isolation built into Android. Chromecast or any "client' connected to the hotspot can see the Internet as that is what hotspot is for; connecting clients to the Internet... If you connect a second client to the hotspot I believe it can see an control Chromecast..

Right.... basically the phone is not on the Tether IP subnet and therefore can not communicate with any device that has a Tether IP address. So Android itself has no access to this subnet it is just internet connection sharing with that subnet.
Not exactly a perfect technical description of what is going on but in the ballpark.
Only the App that is doing the tethering is actually seeing the Tether IP the rest of the phone has no access to it.
Put the phone into hotspot mode, use your tablet to navigate and play. I've done it

I've been able to use AVIA in the configuration you're referring to.

Chromecast without WiFi?

So you can connect a phone that's not on the wifi network to cast videos pics etc. How does it send to the Chromecast?
I thought it had to go through the router or does it stream directly from the phone now?

He is referring to the announcement by Google at Google IO that mentioned being able to stream via proximity without having to be connected to the Local WiFi.
The CCast itself still needs to be connected to a WiFi AP but the phone that is sending to it does not.
It will use location data and show a code on the screen to make a connection over Cell Data.
What they didn't mention is what can be sent to the CCast...
Is it locally stored content?
Is it merely a way to get control and connect to the CCast (For gaming use)
Or does it allow you to do everything you could do if you were connected to the local AP without having to be connected to the local AP...
One thing that is certain is the CCast itself STILL requires having an internet connection and Wireless AP to connect to.
Which the link you posted will help if no other AP is available.
Unfortunately while they announced that feature I don't think it has been implemented or made live yet.

If Chromecast application supports screen casting in your phone then there is a way to cast local media from your phone without external router using phone as WiFi hotspot. Instructions for this can be found from http://forum.xda-developers.com/showpost.php?p=54976131&postcount=36.

Mirroring Content From Android Phone to TV

Hi,
I don't and won't have broadband for several months but want to be able to view online content on a large screen TV.
I got unlimited 4G with Giff Gaff (O2) but they don't allow tethering. I still can tether but it is unstable and gets constantly cut off.
So, I am looking for a work around - not necessarily Chromecast - and thought that I can do the following:
1. Buy Chromecast and connect it to my PC linked to TV or directly to TV via HDMI.
2. Use my mobile phone (Android 4.4.2) to create a WiFi Hotspot and use "Cast Screen" feature on my mobile phone to mirror content streamed via Giff Gaff 4G SIM to the TV.
Will this work?
I mean, I won't be tethering, right?
It will be just mirroring content to the TV via Chromecast and Giff Gaff will only see my phone's IP, right?
Any comments and suggestions will be much appreciated!
Thanks!
In your case, I think Miracast receiver is better, because you need to use your 3G network on your phone to get into Internet. Only Miracast support Wifi Direct features, which does not require the receiver and the device to be within same wifi network.
Chromecast claims to support similar wifi direct, but I personally never tested it. Perhaps, some one else in this forum can share ideas.
The key requirement is in your case, you have to use 3G internet, instead of wifi internet.
