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, and it also uses pre-installed apps that require internet access. So, what can you do if you don’t have Wi-Fi? The answer is easy; you make Wi-Fi. There are plenty of sources that can provide wireless internet while traveling, including Hotel Wi-Fi, portable hot spots, smartphone hot spots, ethernet connections, and more. You can also create a WLAN to use later without an internet connection, although that restricts what the Chromecast can do. Here are the details.
Connect 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, except that the Chromecast still requires an internet source through a host (hotspot, router, or ethernet).
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, but you can’t use Chromecast fully without an internet connection from a host.
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+ are also able to use Guest Mode with certain restrictions, as shown 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 (Guest Mode), so that part is true. However, an internet connection is still required for the Chromecast to offer Guest Mode. You can also mirror devices to Chromecast, which is mentioned below.
Use Chromecast on Wi-Fi 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 simply set up the Chromecast at home with an internet connection using two devices, one for the setup and one for the WLAN. You enable 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 it has an internet connection or not.
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 in your smartphone. You’ll then see your Android phone mirrored to the TV. In this scenario, casting and installed apps will not work, but mirroring will.
Other Ways to Use Chromecast without Dedicated Wi-Fi:
When traveling, the Chromecast can rarely access a dedicated Wi-Fi network, such as hotel internet and local Wi-Fi hotspots. The provider’s two-factor system requires you to accept the service’s terms and conditions, requiring browser functionality that Chromecast doesn’t have.
Some Wi-Fi featured locations, like hotels, also restrict what you can do on their Wi-Fi network. So, what can you do? The answer is to use an ethernet connection, your phone as a hotspot, a portable router (highly recommended due to privacy), and a Chromecast ethernet adapter.
Method #1: Using Your Smartphone’s Hot Spot
By launching the hot spot option in your smartphone, you provide the internet that the Chromecast needs for it to operate correctly. Unfortunately, you still need a dedicated source for the internet. 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 your smartphone has no mobile broadband service for any reason, 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.
Method #2: 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 then connect the device you want to use with the Chromecast, such as your tablet, laptop, or even the smartphone.
Method #3: Use Ethernet
Chromecast does not have an ethernet jack, but Google makes an ethernet power adapter for the device. You simply plug an ethernet cable into the jack, plug the power adapter into the wall, and then connect the USB cable to the Chromecast.
Besides special power adapters, some mobile routers feature an ethernet connection, which you can also use to create the Wi-Fi you’re missing for Chromecast and other devices. All you have to do is plug it into the hotel’s active ethernet wall jack, and you’re all set!
Note: If you want to use a travel router, be sure to 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 completion, follow the steps below.
- Connect your Chromecast to the pocket router/hotspot device via the Chromecast app on your Android or iOS smartphone or tablet.
- 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, mostly if they use 3G/4G/5G as the internet source.
- 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.
Method #4: 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.
Using Connectify Hotspot on a Windows Device or A Smartphone with Hotel Wi-Fi
Step 1Connect your smartphone, tablet, or laptop to your hotel’s Wi-Fi, accepting the terms and conditions, which Chromecast cannot do.
Step 2Open Connectify Hotspot and share your connection as a Wi-Fi network.
Step 3Connect your Chromecast to the new hotspot you have created by 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 a valid internet connection. That connection allows your tablet, smartphone, or laptop to link up, even if they don’t have Wi-Fi. Just remember that the Chromecast still needs a Wi-Fi internet host.
When portable routers (a.k.a pocket routers, mobile routers, portable 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 just another way to use your Chromecast when it cannot access a dedicated internet source, like hotel Wi-Fi.
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.
In closing, yes, you CAN still connect Chromecast (without active internet) to devices, as long as it is used for mirroring.
