How to Use Chromecast without Wi-Fi

Google’s Chromecast hooks up to your TV through HDMI and uses Wi-Fi to connect and stream from most networked devices like smartphones and laptops, and it also uses pre-installed apps that require internet access. What can you do if you don’t have Wi-Fi? The answer is easy; you make Wi-Fi so that a device can connect to Chromecast and operate it online or mirror its display. Sure, you won’t be able to stream content or play online games, but you do get to mirror other devices to the big screen.

How to Use Chromecast without Wi-Fi

You can use Chromecast without a dedicated Wi-Fi source by using one of the following options:

  • Use Chromecast Guest Mode.
  • Use WLAN without internet (following pre-setup procedures) for mirroring a device.
  • Use a mobile hotspot as the router and a second device to connect to Chromecast.
  • Use a travel router for WLAN and your device to connect to Chromecast.
  • Use an active ethernet port, which requires a special Chromecast power adapter.
  • Use Connectify Hotspot on a laptop via an active ethernet connection.

Plenty of sources can provide wireless internet while traveling, including Hotel Wi-Fi, portable hot spots, smartphone hot spots, ethernet connections, and more. However, when internet access is not an option, you can create a WLAN to use later without an internet connection, although that restricts what Chromecast can do. Here are the details.

1. Connecting Devices to Chromecast without Internet

Google certainly improved things when they added Guest Mode, which allows Chromecast to connect to any Google-casting capable device that doesn’t have Wi-Fi internet. However, the Chromecast still requires an internet source through a host (hotspot, router, or ethernet), as shown in the Google image below.

So, can you use Chromecast without Wi-Fi in Guest Mode? The answer is yes, and no. You can use Chromecast on devices without Wi-Fi to mirror the device’s screen. However, you can’t utilize Chromecast’s full functionality without an internet connection from a host, as shown in the Google image below.

If you have not realized the functionality of Chromecast’s Guest Mode Wi-Fi beacon yet, it lets your Android tablet or smartphone’s 4G and 5G streaming apps work directly on your TV. Users with iOS 11.0+ can use Guest Mode with certain restrictions, as shown in the Google image below.

If the above information on using Chromecast without Wi-Fi sounds confusing, you’re not alone. In different terms, you can connect a device to your Chromecast without using the internet, so that part is true. However, an internet connection is still required for Chromecast to offer Guest Mode. You can also mirror devices to Chromecast, which is mentioned below.

2. Use Chromecast on a Wi-Fi Network without Internet

Even with the previous information on casting, that’s not to say that you cannot mirror your tablet, phone, or laptop without Wi-Fi. Google says Chromecast needs a host, but that doesn’t mean that the host must have an internet connection.

You set up the Chromecast at home with an internet connection using two devices, one for the setup and one for the WLAN. You enable the hotspot on your smartphone, connect device 2 (PC, tablet, etc.) to the phone’s hotspot, configure Chromecast using device 2, and then shut down device 2. The Chromecast is now configured to the phone’s hotspot (WLAN), whether or not it has an internet connection.

When connecting the Chromecast to the pre-configured mobile hotspot while traveling, the TV will say it lost the internet. Ignore that notification and select the mirror option from the Home app found on your smartphone. You’ll then see your Android phone mirrored to the TV. In this scenario, casting on-demand streams and installed apps will not work, but mirroring will.

3. Use Your Smartphone’s Hot Spot

The Chromecast can rarely access a dedicated Wi-Fi network when traveling, such as hotel internet and public Wi-Fi hotspots. The provider’s two-factor system requires you to accept the service’s terms and conditions, requiring browser functionality to access it, which Chromecast doesn’t have.

Launching the hotspot option in your smartphone provides the internet that the Chromecast needs for it to operate correctly. Unfortunately, you still need a dedicated source to connect and use on the Chromecast. This scenario means that your smartphone has to serve as the router, so a second device is required to join the network and connect to the Chromecast device.

If, for any reason, your smartphone has no mobile broadband service, you cannot use it as the source for internet connectivity. However, you can still connect in Guest Mode, so without mobile Wi-Fi, what can you do? Check out method #2 below.

4. Use Chromecast with a Travel Router

Grab a 3G/4G/5G portable router with paid service and use it as your hot spot. It’s that simple. No required public Wi-Fi agreements to accept and no insecure internet connections. Connect the Chromecast to the hotspot using your smartphone and Google Home, and then connect the device you want to use with the Chromecast, such as your tablet, laptop, or even smartphone.

When portable routers (a.k.a pocket routers, mobile hotspots) get used as the internet source/WLAN network, they offer actual internet to the Chromecast device as an alternative Wi-Fi source. This scenario is another way to use your Chromecast when it cannot access a dedicated internet connection, like hotel Wi-Fi.

5. Use Ethernet

Chromecast does not have an ethernet jack, but Google makes an ethernet power adapter for the device. You plug an ethernet cable into the power adapter’s jack and an internet source’s ethernet jack, insert the power adapter into the wall, and then connect the USB cable from the adapter to the Chromecast to power the device.

Besides special power adapters for the Chromecast, some mobile routers feature an ethernet connection, which you can use to create the Wi-Fi you’re missing for Chromecast and other devices. You have to plug the mobile router into the hotel’s “active” ethernet wall jack, and you’re all set!

Note: If you want to use a travel router, set up the device at home first by assigning it an SSID and password, unless it uses mobile broadband for Wi-Fi and is already set up.

After getting the right products and accessories, follow the steps below.

  1. Connect your Chromecast to the pocket router/hotspot device via the Chromecast app on your Android or iOS smartphone or tablet.
  2. At your hotel, connect the pocket router to the Ethernet connection if required and an outlet or USB port to power it. Some devices have rechargeable batteries, particularly those using 3G/4G/5G as the internet source.
  3. Connect your devices wirelessly to the pocket router’s connection generated by the ethernet from the hotel’s internet service or by the mobile broadband signal it receives.

The ethernet option does allow the use of Chromecast without Wi-Fi, as long as you got the special AC adapter or attach an ethernet cable to a portable router.

6. Use Connectify Hotspot

Connectify Hotspot is a great way to share your laptop’s Wi-Fi or wired internet connection as a wireless local area network (WLAN) hotspot location. While it is a paid-for app, there is a free version with basic functionality.

The website states that the app requires Windows 7, 8, 8.1, or 10. However, the paid Hotspot PRO and MAX editions also let you use your smartphone’s hotspot to serve as the router for Chromecast. But again, that uses your phone as the dedicated internet provider, so you’ll need another device for casting.

Here’s how to use Connectify Hotspot on your laptop.

Using Connectify Hotspot on a Windows Device or A Smartphone with Hotel Wi-Fi

  1. Connect your smartphone, tablet, or laptop to your hotel’s Wi-Fi, accepting the terms and conditions (via a browser) to compensate for the lack of browser functionality on the Chromecast.
  2. Open Connectify Hotspot and share your connection as a Wi-Fi Router.

  3. Connect your Chromecast to the new hotspot you have created using your smartphone’s Chromecast app.

As you can see, Chromecast is unique from other TV streamers/casters because it features a Wi-Fi beacon that gets used for Guest Mode. Still, that beacon won’t work unless the Chromecast has an internet connection. The network allows your tablet, smartphone, or laptop to link up, even if they don’t have Wi-Fi. Remember that the Chromecast still needs a Wi-Fi internet host unless you only want to mirror a device.

In closing, yes, you CAN still connect Chromecast (without active internet) to devices, as long as it gets used for mirroring. Otherwise, a dedicated internet device and a device to work with Chromecast are required.

Hi, Is it possible to cast my pc while being connected to the internet via Ethernet cable?
Steve Larner says:
I don’t believe you can use ethernet to cast a Chromecast.
Mike says:
Hi Steve

Will all the streaming services now requiring casting (rather than mirroring) I switched to a Chromecast in order to use it with a travel router in a hotel room, and cast downloaded movies from my phone. The Chromecast requires an internet connection to set it up *and* to cast to it. This has the benefit of not consuming mobile data while Im away, but there isnt always an internet connection and at that point everything stops on the chromecast.

Is there any way of casting a downloaded movie without internet? Its not obvious that there is one

Steve Larner says:
If I understand what you said correctly, you can use your phone’s hot spot (since it has internet) to set up the Chromecast and link the two, then use another device (connect it to your existing hot spot) to mirror to the Chromecast. Or, depending on your particular situation, you can connect your working phone to the travel router, then set up the Chromecast to connect to the travel router by using your working phone and Google Home, then try casting or mirroring from your working phone. As long as all devices are on the same network (your travel router), it should work. I might be confused by how you worded everything, but hopefully, this helps. But, as far as I know, casting doesn’t require internet—just a connection to the current network so that it can communicate. Also, try ensuring that Bluetooth is on in the device that is casting before setting up the Chromecast to the network.

Hello, can you help? I want to download shows/movies onto my phone (Samsung SM J320A; android 7.1.1) or my amazon fire 7 tablet (with added google play and such) and be able watch on my tv. But I can’t seem to get either to connect directly. Would a chromecast device fix this? I DO NOT have internet and usually ZERO cell service at my house…..
Steve Larner says:
You can use Chromecast Guest Mode, but you need two devices with internet to set everything up correctly. One device is used for Chromecast setup and the other for WLAN. Enable Hot Spot on the first device (with Internet service) and connect the second device to it. Configure Chromecast using the second device. Then you can shut down the second device, and your Chromecast is now functional using the “non-internet” WLAN network that’s running on the first device. I would try this using someone else’s Chromecast first before you buy one. Sometimes, it can be hard to get things working correctly.
Tina says:
Hi Steve, Can you clarify if a guest is casting to a Chromecast that is on a hotspot is the guest device using its data or is the hotspot that the Chromecast is connected to providing internet for the guest content to play. I have seen it explained different ways. I am trying to work around using my limited hotspot data allowance and use a device to guest cast that has unlimited cellular data.
allan says:
If you’re plugging a hotel ethernet cable into a travel router then the router is now the wifi source for the Chromecast and is providing internet to the Chromecast. So your last sentence is wrong.
Steve Larner says:
Hi allan, sorry for the confusion. The last sentence was just stating what the article is about, that you CAN connect to Chromecast without an internet source WHEN hotel ethernet or other internet sources are not available. You just use that portable router, with or without an internet signal. The closing paragraph has been updated to avoid confusion and make more sense. Thanks!
