How to turn Multicast on Xiaomi router: full instructions with explanations

Multicast technology allows you to simultaneously transfer data to multiple devices on the network without duplication of traffic, which is critical for the network. IPTV, streaming video, online gaming and smart home systems, but on Xiaomi routers (including Mi Router models) 4A/4C, AX3600, AX6000 and Redmi Router) this feature is often disabled by default or hidden in deep settings. Unlike traditional routers, where multicast is activated with a single click, MiWiFi firmware can be challenging, especially if you use unofficial versions of the software or face restrictions from the provider.

In this article, we will not only discuss how to enable multicast through the web interface and the Mi WiFi mobile application, but also explain why the feature may not work even after activation. IGMP your router model, what ISP settings affect multicast traffic, and what to do if the TV or console can not see IPTV-Separately, we will consider the nuances for firmware Padavan and OpenWRT, which are often installed on Xiaomi routers for advanced features.

What is Multicast and why you need it on the Xiaomi router

Multicast (or group mailing) is a method of data transfer in which a single packet is sent to several recipients at once, saving network bandwidth. Unlike Unicast (point transmission) or Broadcast (broadcasting to all devices), multicast optimizes traffic by sending data only to those devices that subscribe to a particular group.

On Xiaomi routers, this technology is used to:

  • ๐Ÿ“บ IPTV โ€” TV broadcast from the provider (for example, Rostelecom, MTS, Beeline).
  • ๐ŸŽฎ Online Games โ€“ Synchronization of data in MMORPG or shooters with a large number of players.
  • ๐Ÿ  Smart home โ€“ managing groups of devices (for example, synchronous lighting Yeelight lamps).
  • ๐Ÿ“Š Corporate networks โ€“ video conferencing or streaming data.

Without the multicast enabled, you may encounter problems: no image on the screen. IPTV, Many users mistakenly think that the problem is in the TV or console, although the root of the evil lies in the settings of the router.

Check Multicast support for your Xiaomi model

Not all Xiaomi routers support multicast out of the box, such as the Mi Router. 4A Gigabit Edition or Redmi Router AC2100 They may have a reduced function, while the flagship AX6000 or AX9000 Provide full support IGMP (Multicast Group Management Protocol).

To find out if your device is compatible, check:

  1. The official documentation is available on Xiaomiโ€™s website in the section of your model.
  2. Firmware โ€“ Multicast may not be available in older versions of MiWiFi (current for routers until 2020).
  3. Hardware restrictions โ€“ some chipsets (e.g, MT7621 Mi Router 3G) supportive IGMP Snooping.

Important: If your model doesn't support multicast on stock firmware, the only way out is to install custom software (like Padavan), but this voids the warranty and requires technical skills.

Enabling Multicast via the router web interface

The most reliable way to activate multicast is to use a web-based control panel.

  1. Connect to the router network via cable or Wi-Fi.
  2. Open your browser and type 192.168.31.1 (or miwifi.com).
  3. Log in (username and password is usually a combination with a sticker on the router).
  4. Go to the Additional Settings section โ†’ Network โ†’ IGMP (The name may differ depending on the model).

In the menu you will see the following options:

  • ๐Ÿ”„ IGMP Snooping โ€“ Multicast traffic analysis to optimize network (enable!).
  • ๐Ÿ“ก IGMP Proxy โ€“ Proxy multicast requests (needed for) IPTV).
  • ๐Ÿ”„ Fast Leave โ€“ Quick group departure (good for dynamic networks).

Recommended settings:

IGMP Snooping: Included


IGMP Proxy: Included (if you use IPTV)




Fast Leave: Included (optional)




IGMP Version: v2 (for most providers)

Enter the control panel (192.168.31.1)

Find the section IGMP subset

Turn on IGMP Snooping and Proxy

Once you have set up, the router will restart. If the multicast doesn't work, check:

  • ๐Ÿ”Œ Connecting the providerโ€™s cable to WAN-port LAN!).
  • ๐Ÿ“‹ Provider settings โ€“ some (e.g. Rostelecom) require binding MAC-address.
  • ๐Ÿ”„ Firmware Version โ€“ Update It Through Settings โ†’ Update of the PO.

Activate Multicast with Mi WiFi

The Mi WiFi mobile app (available for Android and iOS) offers a simplified interface, but not all the features are available.

  1. Open the application and connect to the router.
  2. Go to Settings. โ†’ Extended. โ†’ Network.
  3. Find the Multicast section or IGMP (In new versions of the application, it may be called IPTV).
  4. Activate the switch. IGMP Snooping.

Please note:

Solving Multicast Problems on Xiaomi

If multicast doesnโ€™t work even after you turn on, check the following points:

1. Firmware problems

MiWiFi stock firmware can contain bugs, especially in older versions.

  • ๐Ÿ”„ Update the software through Settings โ†’ Update.
  • ๐Ÿ› ๏ธ Install custom firmware (Padavan or OpenWRT) if your model is supported.

2. Conflict with other functions

Some router options can block multicast:

  • ๐Ÿ›ก๏ธ Firewall โ€“ temporarily turn it off for the test.
  • ๐Ÿ”„ QoS โ€“ Traffic Prioritization Can Hinder Multicast Packets.
  • ๐ŸŒ Double. NAT โ€” If the router is connected to another router, the multicast may not be able to pass.

3.Problems on the provider side

Sometimes multicast does not work due to operator settings:

  • ๐Ÿ“ž Check with support if a link is required MAC-address.
  • ๐Ÿ”Œ Check if the provider is blocking the IGMP on his own equipment.
  • ๐Ÿ“ก Try connecting the console directly to the providerโ€™s cable (without a router) โ€“ if IPTV It will work, the problem in the settings Xiaomi.
How to check if multicast reaches the router?
Use the command in the terminal (Linux/macOS) or via PuTTY (Windows): tcpdump -i eth0 igmp If packets IGMP If you have packets, but they don't get to the devices, it's the router's settings that are to blame.

Multicast on custom firmware (Padavan, OpenWRT)

If the stock firmware does not support multicast, the alternative is to install Padavan or OpenWRT. These firmware offers advanced network settings, including full support. IGMP v3 and MLD (for IPv6).

Instructions for Padavan:

  1. Install firmware (instructions are on the forums) 4PDA OpenWRT).
  2. Go to the web interface (192.168.1.1).
