Using Chromecast in a hotel

I plan to bring my Chromecast with me when I travel, but I imagine the Chromecast will have trouble connecting to the hotel Wifi since most hotels have that gateway page you have to go through before you are actually connected to the internet. Is there an easy way around this without bringing my own router with me?
Thanks!

I travel for a living and live about 1/2 of the year in a Marriott.. Here are a few options that I use.
1. Bring a small travel router - this really isn't as bad as it sounds. Is really easy and they make very small ones. Here is what I use: http://www.tp-link.com/en/products/details/?model=TL-MR3020
2. Connect your laptop via ethernet and use windows to share it via wifi. - This works, but it can be a pain. Some VPN clients really don't like this however.
3. Use a MiFi or Cell Phone in Hotspot mode.
I will either do #1 or 3 depending on the hotel and if I am in the US or not.
Hope this helps...

Worse comes to worse you could always use a phone or tablet as a hotspot!

Thanks for the help! I have Pdanet installed on my gs3, but I haven't been able to set up the Chromecast without a third device in the mix. Using my work laptop is out of the question since I can't install the Chromecast app on it. I don't like to bring my personal laptop along with me on business trips since it's kind of bulky and heavy for a 2 night trip. I have an old Android tablet I can bring along with me to set everything up and control the Chromecast from but it would be awesome if I can get it working with ONLY the gs3 and Chromecast. Is there some way to make that happen? Or will I need a third device in the mix because the gs3 cant be a hotspot and controller at the same time?

I have this same question. I read on the developer site that wireless isolation must be disabled in order to use the chromecast. This could be a problem since most public WiFi has this feature enabled (and if they don't they should!). I have a chromecast, a tablet, and an android phone so if the hotel WiFi doesn't work I can always hotspot with phone and control with tablet. However, this is not ideal since I don't have unlimited data plan. It will be interesting to see how much data the various apps' use. I have 3 trips planned the next 3 weeks and will see how it goes!

A computer with wifi (a computer just jacked into a router in wont work) is a necessary part of setting up chromecast to a new network.
edit: actually i might be wrong on that, testing something now
---------- Post added at 10:51 PM ---------- Previous post was at 10:31 PM ----------
Okay, this is what I just did.
I turned Wireless Tether on my phone on. This means wifi can't be on at all and thus your phone can't be on the same network as the chromecast, and won't be able to control chomecast.
BUT
I downloaded the Chromecast app from the playstore to my Nook HD+. It found the Chromecast on my home network and I tapped on it, and saw my Chromecast on my home network (which the nook was also on). I was able to change it from my home network to my phone. This changed the network both my Nook and Chromecast were connected to from my home network to my phone network. I just chromecasted netflix from my Nook to my TV via chromecast fine. So basically I was able to set it up on a new network with no need for a computer.
So if you are traveling, I believe you are going to need to set up your Chromecast to know your phone's wifi network/password before you go. Why? Because my Nook (or your tablet) can't change the network of the Chromecast without already being on the same network. But at this point, I could now take the three devices anywhere now, plugging chromecast into a TV, setting up my phone to tether, and using my tablet to control it.
Annoyingly, once I turned off tethering, the chromecast borked and I had to re-run setup to get it back on my home wireless network. So, it doesn't seem to save multiple networks, unless I did something wrong.

If needed you could always factory reset your Chromecast by holding down the button for 25 seconds. If you do that, you can set it up from the Chromecast app on your nook and set it to your phone's hotspot.

Thanks for the suggestions! The only issue is that I can't install anything on my work laptop. I appreciate the help though =)

You wouldn't want to connect a chrome cast to public wifi anyways. Then the guy in the room next door could mess with your playback. Travel Router/Hotspot are your best bets (plus being on your own network is a better idea for privacy and security anyways).

I work for a WiFi company and we manage the WiFi for dozens of hotel chains throughout the nation. If you contact the technical support number provided by the hotel they can "Bypass" your Chromecast. All they would need is the IP address or MAC address of your Chromecast, we'll locate it in the DHCP pool and then whitelist it. This will cause it to bypass the login page.

I am pleasantly surprised that they would be willing to do that. I figured anything that could possibly take away from the built in pay for viewing content would not be allowed. The other problem though is Wireless Isolation; it disables wireless clients from being to able to see/talk to each other on the wireless network. This is a problem for chromecast since the "casting" device must be able to talk to the chromecast in order to cast content to it. Do you know how widely used the wireless isolation feature is in the hotel biz? Also if it is enabled is there a way to whitelist the chromecast and casting device so that they would see each other on the hotel's wireless network?

Ah yeah, forgot about the isolation. Most of our configs are set to not allow wireless devices to allow any type of communication with other devices (Allow traffic between wireless clients)

I'd say ask to speak with a Tier2 and explain the whole situation. They may very well disable the isolation for at least that one night if you get lucky. This is all if you visit one of the locations that we manage. Not sure about other companies.

I suppose you could plug a computer into the hotel's hardwire Internet and enable wireless Internet Connection Sharing rather than bringing a router, if you will already be bringing a computer anyway.

actually there is no need of program on the first linkk
on the second link someone pretty much write a code for the steps on the first link

MAC spoofing
I was wondering if this would work.
If I were to spoof the MAC of the chromecast on my cell phone, connect to the hotel wireless, sign in through the gateway, then un-spoof my MAC and connect again with my real MAC. Wouldn't the gateway whitelist both MACs?

Depends if it is whitelisting off MAC or off IP. Either way, you still have wireless isolation problem. There would need to be some type of cloud based controller built-in to chromecast that could forward commands between chromecast and client(s).
Google...if your listening please develop chromecast cloud controller. That would be awesome

Do these things need a wired connection? Those are becoming rare in hotels. Is there a product that creates a personal wifi network, while getting internet from public wifi?

chromecast setup issue

Hey guys quick question just wondering if anyone has had a similar issue with their chromecast setup . This is my second chromecast having the same issue.
I cannot get my phone or computer to complete the setup process. I get an error. See attached picture.
It sees the cast initially and says needs to be setup then after trying to setup I get the error.
Thanks in advance

Is it setup in your WiFi on your phone?

I can choose to connect to it on the wifi network settings on my phone yes.
Also it shows up in the chromecast app as it needs to be set up
Phone : note 3
Chromecast serial : 3A08xxxxx
Router: D link dir-826l (USING 2.4GHZ band to try and connect)
Picture shows the initial screen i get when opening the app and trying to setup.
The number corresponds to the number on the TV but i can never get further than this.

Try rebooting your router. This helped me with connection problems in the past.

I don't think you can setup the Chromecast with your phone. I believe you need a PC to do it. When it's setting up, your PC's WiFi should switch to the Chromecast only; it'lll have some SSID with Chromecast in it. After you confirm the correct Chromecast, it'll do it's setup, and switch the PC WiFi back your LAN.
The error about making sure the Chromecast is nearby means, to me, that the device was not able to connect to the Chromecast. And I think you'll need something that can handle an Ad Hoc setup.

You can set it up with the phone according to the instructions.
I also tried it with the computer and ended up with a similar error during setup.
My next thought is that it could be a issue with the router so I disabled that router and tried an old net gear router I had laying around and that gave me the same issue. From bother the phone and from my laptop (alien ware m11x)
I'm running out of ideas to try
Thanks for the help guys.

Don't trust the status in the Chromecast application - check what it says on the TV.
Try using the HDMI extender
Move Chromecast closer to the router, or if it's within 5 feet, farther from the router (constructive and destructive interference)
Move Chromecast away from other Bluetooth and WiFi devices if at all possible
If running setup on a PC, be sure the PC has only the wireless enabled, and no VPN connection running. Multiple adapters and VPN have potential to confuse the setup process.
Make sure your phone is connected to your normal WiFi first
Be sure that MAC filtering and AP isolation are not enabled in your AP/router.
Try a factory reset

Actually it's the exact opposite unless your PC has a WiFi card. It requires any device that can run the setup file and that device MUST have WiFi.
In this case I have to wonder if the OP is using a custom ROM. I believe you need to be able to make an AdHoc connection with the Chromecast for setup. Some custom Roms don't support this.

If this is the case, nothing is mentioned in/about the Windows PC app.
EDIT: My CC is setup but I installed the PC app and it won't even open and later shows a Turn On WiFi box.

AFAIK, it's a standard access point connection, but yeah, custom ROMs could be problematic for other reasons as well.

Yep in order for the setup utility to work on a PC the PC must have a WiFi card in order to communicate via AD HOC with the Chromecast.
It uses AdHoc to control the unit until it has been configured to work with the available AP. Once it is connected to the AP you can use the PC to stream to it without WiFi as long as it is wired to the same network.
But Setup of Chrome requires WiFi. And of course a device that has a compatible setup program to run.

I have Dlink dir 655 and got th same phone . I enabled multicast on dlink router and it worked. Probably after i restarted the router used the chromecast app and connected it smooth

Yes once set up it is a standard AP connection but to set it up to connect to an AP for the first time requires an Ad Hoc connection with the device running the setup program.

Ok thanks for the help guys I'll give another go tonight. Also just for keeping up to date my phone is not rooted and is running a stock rom obviously.
I'll report back to any results.

I'm having the same problem. I am running a custom ROM on my phone though. I do not have a laptop, only a desktop PC without WiFi.
EDIT: After reading some of the advice in this thread, I went back to my stock ROM to see if I could set it up then. It worked instantly. For me it was the ROM I was on.

Needing to have WiFi on the PC could be an issue for some. Since this point isn't mention anywhere on Google's Chromecast pages that I could find, I'd be annoyed if I found this out after purchase!

It is sort of mentioned...It does say connect via WiFi....
Truth is this setup procedure is not all that different than any other Wireless Appliance you would buy.
Wireless Print Servers, WiFi Boosters, all work on the same setup principle.
Unless they can be wired directly into a network it is assumed you will connect to them via AdHoc to then set them up for use with your AP.
There is no way an appliance can connect to an AP that is protected without Human help (would defeat the purpose of having Protection if it could wouldn't it? Anything could do that then). SO barring a Direct connection with a device to set it up the only way to do so is via AdHoc Wireless mode that then lets you communicate to set it up for Infrastructure mode.

I just checked with both my phone and laptop. It's a standard Access Point (Infrastructure) connection for setup. Makes sense, as you noted previously that not all devices and ROMs support Ad Hoc mode.

Devices with can use WPS. But both the AP and the device must support WPS, so much easier and more compatible to either allow a temporary open AP as Chromecast does, or use an Ad Hoc connection.

I had the same problem I was able to get it to connect with laptop on wifi not hard wire once that works then you can use your phone to work chrome cast

Yes, it does say that but also states that it's Windows compatible. Connecting to a laptop is mentioned which means anything but a real old one would have WiFi. They clearly have left out mentioning Desktop PC. After setup then using Chrome, a Desktop PC can be used unless you have WiFi card or a WiFi USB adapter which I actually have on my Samsung Smart TV.

Chromecast app disconnecting after screen mirroring selected

Hey if anyone has the same problem and could share a solution i would be thakful. I'm trying to mirror my cell phone screen throug chromecast app. When in click in cast screen, the app finds my chromecast device connected to the TV. Then i select it, the connection is then stablished, the cell phone screen appears on TV, but imediatelly the chromecast app shows the "Disconnecting" message, automaticaly. After that, the chromecast app can't find the device on my wifi network anymore, just a few minutes later after a new search the device becomes identifiable again. Seems that the app is somehow making the Chromecast device to disconnect from the network. I've tryied to reset the chromecast device, to reinstall the chromecast app and i've disabled the AP isolation in my router and even tryied to disable the firewall, nothing worked what makes me belive it's an app issue.
Cell phone: Samsung S4 mini DualSim GT-I9192 with Andorid 4.4.2
Chromecast app: Version 1.7.4
Chromecast device firmware: 17977
TV: LG LM476200
Router: ARRIS TG862
Sorry for the english and thanks in advance.

Same here, same devices.

With my Note10.1 2014, a supported device, the CC app showed on tv, but the Note froze, which never happened before.
I haven't given it a second try, I'm 99% sure that this will happen every time, and I don't know any variation of the mirroring process or device setup, which might possibly lead to success.

If the device is supported for Cast Screen and it is using the stock ROM, then it should work. If it's not using the stock ROM, there is no guarantee of success.

Still stock & non rooted.

Sometimes I find the casting is flaky if I'm connected to a 5 GHz wifi network, as the phone has to communicate via the router rather than directly with the Chromecast at 2.4 GHz.

I'd try it again. Screen Casting is high load on the system, so it could be heat or stress related.
My Galaxy S3 casts solidly as long as the battery isn't low, it's not overheating from being charged while casting, and the WiFi is strong.

It still communicates through your router in both cases. It's not WiFi Direct like Miracast. That said, I have seen reduced stability when casting from a 5 GHz device in newer firmware builds. It's still less bandwidth load on the bands, but it can be subject to issues if the router doesn't bridge the two networks efficiently.

Interesting, I was always under the impression that devices on a wireless LAN could talk to each other directly if they were capable of seeing each other's signal. I guess not, then.

Standard AP/Infrastructure mode routes everything back through the router - it's a star topology. Easiest to manage and control, but you can be limited by the router/AP's processing speed (hence the different classifications for Wireless N, and the different real-world speeds even within those classifications).
Ad Hoc mode is peer-to-peer but has some limitations (fixed channel, limited range, etc)..
WiFi Direct is more of a small-scale AP setup and requires some hardware/driver support.
Things might change with the promise of "cast without being on the host's WiFi network" that was announced, but we'll have to wait and see.

Found some solution?

Did you managed to find some solution? :good:

Did anyone find a fix to the original problem? I'm having the same issue on my S7 Edge. It worked fine, then one day I tried to mirror my screen and it says "Connecting" then immediately afterwards it says "Disconnecting". However, Chromecast can mirror screen just fine on my S4 that's on the same network.
Setup: Samsung Galaxy S7 Edge (SM-G935T), Chromecast is connected via Mobile Hotspot. Samsung Galaxy S4 is connected to Mobile Hotspot as well. I DO NOT have a wireless router nor do I plan on getting one. Any fixes would be greatly appreciated.

Hi,
Managed to fix this by allowing microphone in permissions for all Google apps including Google play services and Google play services for Instant apps.
Hope this fixes your problem. :good:

Hey! Found a fix for this on the S7 Edge. I think it did have something to do with the 5 ghz band.
1: Turn on your phone's wifi
2: Allow it to connect to your chromecast
3: Turn on Smart Network Switch
4: Allow Aggressive Switching
5: Turn on your Mobile Hotspot
6: Allow your Chromecast to connect
7: Once the Chromecast is connected to the Mobile Hotspot, Pull down menu and click to turn wifi off, wait one second, then turn back on.
You should be able to mirror and cast then.
Hope this helps. Not an engineer, can't tell you why this works, maybe there is a more simplified way. I've also heard of clearing the data and cache from the Google home app, but that stopped working for me as I'm sure this method will someday too.
But for now, enjoy!

This is not a satisfactory solution for me. Why should I let Google spy on me with my microphone just to cast my screen?

I have 1gen and 2gen Chromecast and both stopped screen casting (mirroring) with Pixel running Oreo. Works fine on Nexus with 7.1.2

[Q] Chromecast w/o WiFi

Hey guys,
I'm gonna be moving into a new apartment in a couple days and will not have WiFi until march (thanks TWC :crying.
I know about the guest mode that lets your friends locally connect and cast, my question is can I do this without having a "parent" WiFi connection? Like can I use LTE to stream netflix through the Chromecast from my phone WITHOUT having a router at all?
I can connect to the internet/update it at my parents before I leave if that matter at all.
Thanks in advance !

Yes. Set up wifi hotspot on your phone and connect to it.

herp, didn't even think of that. Thanks for the prompt response

Didn't want to start a new thread. For some reason, I can't get to see the cast icon when not on wi-fi. Guest mode is enabled and I can see the shared pin on the TV, but my phone (LG G3) just doesn't want to cooperate. I'm running 5.0.1 on it and it works just fine on wi-fi, but not when LTE is enabled.
Any ideas? Thanks!

Setting up chromecast without WiFi

So I'm in the army right now, which means there's a TV but no WiFi available.
I did think of just setting up a Hotspot with another phone but it gets pretty annoying having to have 2 people at all time.
So I went digging in the Internet and found someone at a random forum (can't find it now for credit..), that said that If you set up the Hotspot in your own phone and configure it with another one you don't need the other one around anymore - being the Hotspot works as being connected to it.
Now I'm pretty sure there shouldn't be any reason I couldn't set it up on my own phone (the hotspot), except the Google home app just demands I connect to the WiFi network, which I can't do because you can't connect to yourself sadly.
I think if someone made some changes to the Google home app, or made an alternative set up app it could work. I have no idea how to code an app, so I came here ?
tl:dr I Want an app that does the same as the home app for setting chromecast up, but without checking if I'm connected to a WiFi network. (I think)

I'm guessing that you have no WiFi but you do have a hard line internet connection?
The only issue with what I'm going to suggest is that base rules may prohibit creating a WiFi access point on any of their hardline connections.
But the best solution for you is to buy a Portable Router (see posts here about using CCast in a Hotel).
It's a small box about the size of a DC transformer that plugs into the outlet and also any Network to create a small footprint WiFi access point.
I suggest looking for a model that also has Repeater mode that allows it to connect to another WiFi access point to create your own private network as opposed to a hard line.
It is probably the best way to use a CCast in places where WiFi is not available without having to play with Phone Hotspot which doesn't always work due to the fact the hotspot can't control the CCast in that mode.
The other Option that is most likely to be allowed is to add a WiFi puck to your Mobile account. Then there would be no potential compromising of the Military network (which is why they might not allow the Portable Router to be used) and you would no longer need two phones to run the CCast.
CCast definitely needs Internet so that Puck might be the safest and best way forward for you.
As for what you read...The issue is that if the Phone goes out of range it stops working.

Actually, no Internet at all, just mobile data, but since I got 15 gigs it's OK for me to use it.

To be honest, it is a good idea but my I was mainly wondering if I could solve it via software which is both easier obviously and also I just wanted to know if it's actually possible since I thought of it and I wanna know if I got it right

Not really...All the hacks and such that people try simply don't work well due to the fact that the Phone can't really connect to the same subnet as the Hotspot. When you go into Hotspot mode you can't also connect to that hotspot internally because WiFi is no longer available to the phone.

That's why i suggested tempering with the app so it treats being a Hotspot as if u were with WiFi on connected to one.
Basically take off the check for being connected to WiFi.

The issue isn't the app...It's the fact that the WiFi in your phone can only do one thing at a time....BE an Access Point or CONNECT to an access point.
It can't connect to itself as the radio can't do both things at once.
So when you go into hotspot there is no way to get on the same subnet as the hotspot with the phone.
Because there is no network adapter available to connect to it. It is too busy being an access point.
Basically going into hotspot turns the Phone into a router. A router the phone has no way to connect to. So you either need another device to connect to that phone router or find some other router with internet.
Which is what the Cellular Puck will give you.

Like I said, once the setup is done, being the Hotspot is just like being connected to is. The app still doesn't recognize you're connected but if you're on the web the chromecast icon does pop up when needed, all the third party apps do recognize you as being connected.

All you managed to do with Google Home (which can't be edited by anyone but Google)on the second phone is connect your CCast to the Phone Hotspot for it's Internet. There is no way to avoid that setup....HOWEVER...
As long as you don't set it up to connect to some other Hotspot there is no need to run Home again, Just turn on Hotspot and it should reconnect.
It will even remember the password,

Yea I know, but sometimes friends take it or something and it's a pain in the ass to explain everything, and even when I do it means I gotta reconnect at my end again which is annoying just thought someone could maybe find a solution that sounded really simple for me, guess not, too bad..
Thanks anyway!

Well trying to recode Home is a dead end....Android wouldn't even let you install it!
You guys should just chip in and buy the puck.
It will even let you use Tablets and Laptops as well as simplify the CCast use.

I know this is an older post; not sure if you are still interested. I read all the replies and not sure what to make of it as far as if anyone had a working solution or not. No disrespect to anyone, but I couldn't tell for sure so I'm posting a link to my solution which does work. The two important steps are included. One is using " other wifi" in the drop down list when searching for your hotspot. The second is enabling GUEST MODE.

I’m trying something similar with a Chromecast 3rd gen and iPhone 5S (iOS 12). Main issue seems to be guest mode doesn’t work at all on any apps, and pretty much every solution i’ve seen to this results in guest mode being used for the eventual casting. If you have android or iOS 13 then ymmv.
The only solution i’ve found are workarounds, the obvious being
1) don’t buy a chromecast (it’s not much of a solution but hey it’s $30).
2) use a secondary device to cast.
3) use a tethered travel router, and this can be done with only a phone and mobile data for internet, but there’s a catch:
First i’d Recommend any router by GLi.net (cheapest “mango” router is about $20) as they support iOS and android and both WiFi and usb tethering.
Also, i’ve Tried using a WiFi hotspot on the phone, and it’s the same issue - no connection to the chromecast regardless of how. However... iPhones will allow you to create a hotspot using *only* cables usb tethering, so if you set the router up to *only* accept internet via cables tether (turn off WiFi/repeater tethering), then you can have both the chromecast and iPhone connect to the routers WiFi, whilst providing net access to the router (and WiFi network) from the same iphone’s mobile data via usb. Simple howoto:
Important: Turn OFF WiFi on the phone, and turn off hotspot.
Connect phone to router via usb, accept trust settings.
Turn on personal hotspot, you’ll get a message asking whether to use WiFi or just usb (andbluetooth if it’s also turned on). Select just usb/Bluetooth.
Wait until blue connection bar shows on phone (if not, make sure routers setup properly to gain net via usb tethering).
Now, turn on WiFi on the phone, and connect to routers WiFi.
Setup chromecast as normal, selecting to connect to routers WiFi too.
Note turning hotspot off and on again whilst WiFi is running will start a hotspot on WiFi and disconnect you from router WiFi, so you’ll always have to go through process of turning WiFi off, turn hotspot on, turn WiFi on.
So you can do this with the right router and a usb connection to phone. Or maybe android and working guest mode. Otheriwse, ...fire tv anyone?
