Setting up a router for stable data transfer

The quality of wireless streaming directly depends on the configuration of your network equipment. Users often encounter situations where their phone sees the TV, but the connection constantly drops or the image is choppy. In most cases, the cause lies in the router settings, which require manual adjustments to optimize streaming.

First, you need to log into the router's web interface. To do this, enter the gateway IP address (usually 192.168.0.1 or 192.168.1.1) and enter the administrator login and password. Find the wireless network settings section (Wireless Settings). It is critical to select the correct channel width here. For the 2.4 GHz band, it is recommended to set the value 20 MHzto reduce interference from neighboring networks, although this will reduce the maximum speed. For 5 GHz, you can leave 80 MHz or Auto.

Also worth paying attention to is the function IGMP SnoopingEnabling this feature allows the router to intelligently distribute multicast traffic used for video streaming, sending data only to the device that requested it. This reduces the overall network load and prevents channel saturating.

If you have a dual-band router, make sure the "Smart Connect" feature (which combines 2.4 and 5 GHz networks under a single name) is working correctly. Sometimes devices get stuck on different frequencies and can't see each other. In this case, temporarily separate the networks by giving them different names (e.g., HomeWiFi And HomeWiFi_5G), connect both devices to the 5 GHz network and check the operation.

Troubleshooting and diagnostics

Even with proper setup, situations may arise where the connection is impossible or unstable. One common issue is that the phone simply doesn't see the TV in the list of available devices. In this case, the first thing to try is restarting both devices. This simple action often clears the network service cache and resets frozen discovery processes.

If the issue persists, check your date and time settings. Both devices should have the current date and time, preferably set to automatic network synchronization. Time desynchronization can lead to security certificate errors, preventing the handshake between the devices.

Another common cause is antivirus software or firewalls installed on the router or in security apps on the smartphone. RedmiThey can block ports required for the protocol to function. Miracast or DLNATry temporarily disabling network protection or adding devices to the exception list.
