WiFi channels 1, 6, and 11 are non-overlapping (Overlapping makes wireless network throughput relatively low). If the problem persists, try toggling between the different numbered channels until you find one with the least interference. If set to ‘Auto,’ try changing it to any of the available numbered options. Please note that the names of these menus could also vary depending on your router. Go into your router’s settings and look for a menu called ‘Wireless’ and another menu under it called ‘Channel and SSID.’ But sometimes, interference can occur (for example, if you and your neighbors both use the same channel).

Usually, the channel is set to ‘Auto’ by default. Most routers allow you to toggle between the different wireless channels that they run on. Sometimes if you’re facing connectivity issues, your Chromecast will be connected but can’t cast. If you’re already connected to a network, or you wish to update the password, select “Forget” and then tap “Forget this Network”. You can select the appropriate network and enter the right credentials to connect your Chromecast to Wi-Fi. When your setup is complete, tap on the device on your Google Home app home screen, hit “Settings” on the top right corner, and select Wi-Fi. Follow the instructions that appear on-screen to finish your setup. Your phone will now search for your Chromecast. If you haven’t set up your device yet, tap the Add button on the top left of the Google Home app home screen, then select “Set up device” and then “New device”.

Connect Chromecast To Wi-FiĮnsure that your Chromecast is plugged into your TV, and launch the Google Home App.

Next, try forgetting the network on your Chromecast and reconnecting to it using the right credentials. The easiest way to rectify this error is to ensure that you connect over the same Wi-Fi network for both the mobile device and your Chromecast device. Sometimes, a poor connection can lead to a related, yet different error called the Source Not Supported Error. In some cases, users install a second Wi-Fi network in their home and end up with the Chromecast and mobile devices on separate networks. The most common cause for this is changing your Wi-Fi password but forgetting to update it on your Chromecast device. There could be many reasons why your Chromecast isn’t connecting to your WiFi.
