QoS (Quality of Service) technology in Xiaomi routers is designed to prioritize traffic โ it automatically distributes bandwidth between devices and data types (for example, gives an advantage to video calls before downloading files). However, in some cases, QoS may not live up to expectations: slow down the overall speed of the Internet, create delays in games or conflict with the Internet. VPN. If you notice that the network is slower after activating this feature, shutting it down may be a solution.
In this article, weโll discuss how to deactivate QoS on popular Xiaomi router models (including Mi Router). 4A, AX3600, AX6000 And others, what the implications are, and where it's really useful, and how to check if QoS is enabled on your device, and what to do if it's not on the menu.
What is QoS and why do you want to shut it down?
QoS (Quality of Service) is a traffic management mechanism that analyzes data packets and prioritizes their processing, for example, a router can give the advantage of:
- ๐ฎ Gaming traffic (decreased ping in online games)
- ๐ Voice calls (VoIP, Zoom, Skype)
- ๐ฅ Streaming video (YouTube, Netflix on YouTube) 4K)
However, there is a downside to the technology: First, QoS requires additional computational resources of the router, which can lead to slowing down the device when the load is high (for example, when connecting 20).+ Second, prioritization algorithms are not always perfect: they sometimes mistakenly strangle important traffic (e.g. torrents or system updates) as secondary. VPN, IPTV or user-specific settings MTU.
When should I turn off the QoS?
- โก Your network is slower than direct from the provider (via cable).
- ๐ฎ Online gaming has lags despite high-speed fare.
- ๐ Torrents or file downloads are โslowingโ for no apparent reason.
- ๐ The router overheats or reboots frequently.
How to check if QoS is enabled on Xiaomi router
Before you turn off the feature, make sure it's active. Depending on the Xiaomi model and the MiWiFi firmware version, the path to QoS settings may be different. Here's a universal way to check:
- Open the routerโs web interface by going to 192.168.31.1 (or miwifi.com) in your browser.
- Log in with your login and password (by default โ admin/router sticker).
- Go to the Additional Settings section (or Advanced in English).
- Find the QoS tab, Bandwidth Control, or Bandwidth Control.
If the section is missing, it means:
- ๐น QoS is not supported by your router model (e.g. Mi Router). 3G or-outdated).
- ๐น The function is hidden in the alternative menu (see the next section).
- ๐น You have custom firmware installed (such as OpenWRT) where QoS is configured differently.
๐ก
If the routerโs web interface does not open, check the cable connection or reset the settings to factory settings (reset button for 10 seconds).
Step-by-step: how to disable QoS on different Xiaomi models
The process of shutting down depends on the firmware and model, and below are the instructions for the most common devices.
Mi Router 4A / 4C / 4Q (MiWiFi firmware)
- Go to the web interface at 192.168.31.1.
- Go to Additional Settings โ QoS.
- Uncheck the tick from Enable QoS (or switch to Off position).
- Click Save and restart the router.
Mi Router AX3600 / AX6000 / AX9000 (MiWiFi or International Firmware)
On new models with Wi-Fi 6, the interface may differ:
- Open miwifi.com โ Advanced Settings.
- Choose QoS Settings or Traffic Control.
- In the QoS Status section, install Disabled.
- Apply the settings and wait for the reboot (can take up to 2 minutes).
Routers with firmware Xiaomi HyperOS (new models of 2026)
In the fresh firmware based on HyperOS QoS can be hidden in the menu Intelligent management:
- Go to Settings. โ Network โ Intellectual management.
- Find the Traffic Prioritization block and disable it.
- Save the changes.
โ๏ธ Preparing for QoS shutdown
If the speed has not changed after the QoS shutdown, check:
- ๐ The quality of the cable connection to the provider (maybe the problem is on his side).
- ๐ก Channel overload by other devices (use Traffic Monitor in router settings).
- ๐ Firmware updates (sometimes QoS bugs are fixed in new versions).
What to do if QoS is not on the menu?
If a QoS partition doesn't show up, it doesn't always mean the feature isn't there. Possible reasons and solutions:
| Problem. | Reason. | Decision |
|---|---|---|
| No QoS tab. | Outdated firmware | Update the software through Settings โ Update |
| QoS is hidden | Regional restrictions (Chinese firmware) | Install an international or custom firmware |
| Function disabled by default | The model does not support QoS (e.g. Mi Router Mini) | Use alternative methods of traffic management (e.g. Limit) ARP) |
| QoS is only available through the application | Limitation of the web interface | Manage settings through Mi WiFi App |
For models with Chinese firmware (for example, Xiaomi Router) 4A Gigabit Edition may need to be unlocked via SSH But it's risky: informal firmware can take away warranties or cause instability.

Consequences of disabling QoS: pros and cons
Disabling QoS doesn't always lead to improvements. Let's look at the real consequences:
Pluses
- โก Maximum speed increase (5-15%) due to lack of packet processing.
- ๐ฎ Reducing ping in games (especially relevant for the CS:GO, Dota 2, Valorant).
- ๐ More stable with more connected devices (20)+).
- ๐ฅ Less router heating (QoS loads the processor).
Cons
- ๐ Deterioration of VoIP Call Quality (Possible Interruptions When a Network is Busy).
- ๐ฅ Lags in streaming video (YouTube, Netflix can โslow downโ when you download files in parallel).
- ๐ Uneven speed distribution between devices (one client can clog a channel).
If you use a router for a gaming PC or workstation, disabling QoS is often justified. For a home network with many devices (smartphones, TVs, smart appliances), it is better to test the network with QoS on and off at different times of the day.

Disabling QoS is most effective at rates of 100 Mbps or higher. On slow connections (up to 50 Mbps), the difference is usually not noticeable.
QoS Alternatives: How to Manage Traffic Without Built-in Tools
If you have disabled QoS but want to maintain control of your network, use alternative methods:
Manual prioritization of MAC-address
In most Xiaomi routers, you can manually prioritize specific devices:
- Go to Settings. โ Local area network โ Devices.
- Find the right device and press Control.
- Set high priority (or low latency for gaming).
2. bandwidth restriction (Bandwidth Limit)
If one client clogs a channel (such as torrents), limit its speed:
- In the web interface, open Additional settings โ Bandwidth management.
- Add a rule to MAC-device-address.
- Specify the maximum download/return speed (e.g. 50 Mbps).
3. Use of third-party firmware
Firmware like OpenWRT or Padavan offer flexible traffic management tools, including:
- ๐น SQM (Smart Queue Management โ an advanced alternative to QoS.
- ๐น Prioritizing by port (e.g. for gaming consoles).
- ๐น Real-time traffic usage schedules.

Before installing custom firmware, check compatibility with your router model on the forum 4PDA. The wrong firmware can โbrickโ the device!
Frequent Mistakes and How to Avoid Them
When you turn off QoS, users often face typical problems, and here's how to prevent them:
โ ๏ธ Attention: If the router starts to reboot frequently after the QoS shutdown, check the CPU load. It may be overheated by the large number of connected clients. Solution: limit the number of devices or install active cooling (for models without a fan).
Error 1: QoS is off, but the speed has not increased
Possible causes:
- ๐น The problem is on the provider side (check the speed by connecting directly to the modem).
- ๐น On. DNS-proxy VPN on the router (turn them off in Settings) โ Internet).
- ๐น Parental Control is activated, which also manages traffic.
Error 2: After disabling QoS, some sites are lost
This may be due to:
- ๐น MTU-conflict (try to establish a conflict) MTU=1472 in settings WAN).
- ๐น Lockdowns ICMP-Packages (enable Ping from the external network in Settings) โ Security).
Error 3: QoS turns on after restarting
Decision:
- Reset the router to factory settings (reset button for 10 seconds).
- Update the firmware to the latest version.
- If the problem persists, install custom firmware (e.g. Padavan).
