What TV are you.

Cause analysis: It may be that the system cannot recognize the WiFi signal.

Solution: Turn off and restart the current TV wifi connection and cannot access the Internet, it is recommended to turn off the TV first, cut off the power, leave it for 30 seconds, connect the power supply, and restart the TV. Restart the machine and reset the system so that the system can re-identify the WiFi signal.

Here's how:

2. Restart the router, it may be because the router has been on for too long and the signal is too poor.

Restart your modem and router.

The modem and router are generally in a long-term working state, and individual families will not turn off the router or modem when using the wifi network, and the system will inevitably have data errors in long-term operation, so in the case that the wifi cannot be connected, you can try to restart the modem or router.

The solution to Zheng Pei's decision is as follows:1.Check whether the wifi network is in normal networking state, if the wifi network is disconnected, it may also affect the normal use of the screen projection function;

3.If the user is projecting the screen through the **app, it is possible that the **content is protected by copyright, and does not support any projection, screen recording, screenshots and other behaviors that may infringe on copyright, and only supports the user in the authorized port**;

4.Users can also try to shut down and restart the device, or upgrade the system version to the latest before casting the screen.

This is because the TV itself does not have a projection sensitive group function.

The most quiet way to judge the economy is to add a screen projector or set-top box, add a set-top box or screen projector, and make the TV a smart TV. You don't have to spend thousands of dollars on a TV.
