What problem is Chromecast solving

Chromecast: Troubleshooting the most common problems

Is Google Chromecast causing problems? We have put together solutions for the most common problems here. We'll show you, for example, how you can reset the Chromecast, how you can easily improve WiFi reception and show you when you should complain about your device.

For everyone who is new to the Google stick: Chromecast is a compact streaming client. It connects to the TV's HDMI port. You can then stream video content from Google's Chrome browser and Android devices to the television. The device costs 35 euros and can only be connected to the network or the connected devices via WLAN.

Problem 1: Screen occasionally goes black

If the picture keeps failing or the Chromecast even restarts, the first thing you should check is the power supply. Most users simply plug the Chromecast into a USB port on the television for power. As long as everything works perfectly - great.

1. Power supply instead of USB connection

In all other cases, you should use the power adapter that came with the Chromecast to power it.

2. Reset the Chromecast

If that is not enough to solve the problem, reset the Chromecast to the factory settings. To do this, press and hold the button on the device for 25 seconds until the light starts flashing.

3. New power supply or complaint

If this trick doesn't work either, you can still replace the power supply unit and the USB cable. However, we tend to complain about such problematic devices.

Problem 2: Videos get stuck regularly

This is mostly due to a weak WiFi signal. You can see the signal strength in the lower left corner of the Chromecast's screensaver, i.e. the image that is displayed when you are not playing any videos. If this signal confirms the suspicion, then you should also use another WLAN-compatible device (e.g. smartphone) to check whether reception is in the vicinity of the television:

1. Use a longer HDMI cable

Sometimes it is the television itself that shields the WiFi reception. If a deviation of a few centimeters is enough for a significantly better signal, you simply have to reposition the Chromecast. You will need a longer HDMI cable for this.

2. Use the WLAN repeater

If other devices near the TV suffer from a weak WiFi signal, you should improve your WiFi accordingly. In specialist shops you will find so-called WLAN repeaters with which you can amplify the signal.

Problem 3: Videos only get stuck sometimes

This is mostly due to a temporarily overloaded WLAN. Background: All devices in your WLAN share the wireless bandwidth. Therefore, a large WiFi file transfer in the study can interfere with the Chromecast in the living room.

1. No data transfers when Chromecast is running

Modern routers automatically put less time-critical tasks behind video and audio streams as well as internet telephony. But that's still not the rule. In addition, there are hardly any home routers where you can manually intervene in these settings (so-called Quality of Service, QoS). This is why it is easier for most users to manually organize the rest of the network traffic differently, to restrict larger file transfers to the network cable during television hours, or similar.

2. Select another WLAN channel

Frequency interferences on the frequency band used by your WLAN are also possible causes. These are caused, for example, by other WLANs, but also, for example, by a microwave device.

If you have a FRITZ! Box, you can see in its settings which other WLANs are still broadcasting on "your" WLAN channels. The WLAN can be reconfigured on this basis. Since the Chromecast only transmits in the 2.4 GHz range, it is not possible to switch to the less loaded 5 GHz range.
