First, use our self-help flow to troubleshoot a Chromecast connection issue.
Troubleshoot a connection issue
Can other devices connect to your Wi-Fi network?
Are you at a place of business, hotel, school, or dorm?
Chromecast doesn’t support networks requiring connection through a captive portal, which is typical of hotels, schools, dormitories, or business. You won't be able to connect to these types of networks.
Are you using a Wi-Fi hotspot?
Check if your Chromecast is within 15 to 20 feet of both your setup device and the Wi-Fi router.
Note: Support for Chromecast (1st gen) has ended, which means it no longer receives software or security updates, and Google doesn't provide technical support. Users might notice a degradation in performance.
You can also follow these manual steps:
Step 1. Reboot the following devices:
-
Wi-Fi router
- Unplug the power source for about one minute before plugging back in.
Note: If you're unable to set up using the Netgear Nighthawk router, then you might need to:- Disable Access Control
- Enable Allow guests to find each other and access my local network in "Guest Network Setup."
- Unplug the power source for about one minute before plugging back in.
- Chromecast device
- Unplug the power cable from the Chromecast device.
- Leave it unplugged for one minute.
- Plug the power cable back in.
Step 2. Turn Wi-Fi off and on from the mobile device you're using to set up the Chromecast device.
- On your mobile device, tap Wi-Fi.
- Turn Wi-Fi off, then on again.
Step 3. If you have a dual band router, try setting up Chromecast on either the 2.4 or 5 GHz bands.
Dual-band routers might broadcast 2 networks with similar names but have 2, 2.4 G, or 2.4 GHz as part of the 2.4 GHz band name, and 5, 5 G, or 5 GHz as part of the 5 GHz band name. For example, if your Wi-Fi network name is "Home", you might find "Home2" and "Home5" in the list of available networks.
Note: Chromecast (1st gen) is only compatible with 2.4 GHz Wi-Fi networks, so it won't list 5 GHz networks during setup.
Step 4. Perform a factory reset.
