Did you notice that the internet on your Xiaomi Mi Router is slower than it should? pages load forever, videos in the video 4K And it's not always the provider that's the problem, it's often the router that's the fault. AX6000 or AX9000 can brake due to incorrect settings, congested channel or outdated firmware.
In this article, we will discuss 10 proven ways to increase Internet speed on Xiaomi routers, from basic (change Wi-Fi channel) to advanced (QoS optimization and alternative firmware). 4A, AX3600, AX6000 Redmi Router AX5. You will learn how to diagnose a problem, which settings to change first, and when to contact the provider.
Important: the speed depends not only on the router, but also on the provider’s tariff, type of connection (optics)./ADSL), We're going to focus on the things that you can fix yourself without buying new equipment.
1. Check the real speed of the Internet
Before digging into the router's settings, make sure the problem isn't on the provider's side. Connect your computer or laptop to the router via cable (LAN-and pass the speed test on the port:
- 🌐 Speedtest.net (the most popular service)
- 📊 Fast.com (from Netflix, shows speed for streaming)
- 📶 Speedtest.cn (Relevant for Chinese Servers)
Compare the results to your ISP's rate, for example, if you have a 100 Mbps tariff and the test shows 12 Mbps, the problem is not the router. If the cable speed is normal and the Wi-Fi speed is sagging, read on.
⚠️ Warning: Test your speed at different times of the day. In the evening (from 18:00 to 23:00) the speed may drop due to overload of the provider's network - this is normal in many regions.
| Provider's fare | Minimum cable speed | Minimum speed over Wi-Fi (5 GHz) |
|---|---|---|
| 30 Mbps | 25-28 Mbps | 15-20 Mbps |
| 100 Mbps | 85-95 Mbps | 50–70 Mbps |
| 300 Mbps | 250–280 Mbps | 150-200 Mbps |
| 1 Gbps | 800-900 Mbps | 400-600 Mbps |
If the cable speed is the same as the tariff and the Wi-Fi speed is much lower, move to the next section, and if the cable speed is low, call the provider and request a line check.
2. Optimize the Wi-Fi channel and frequency
The most common reason for slow Wi-Fi is congested channel. In apartment buildings, dozens of routers broadcast on the same channel, causing interference. Xiaomi routers default to select the channel automatically, but this algorithm is far from perfect.
To choose the best channel:
- Open the router’s web interface at 192.168.31.1 (or via the Mi Wi-Fi app).
- Go to Settings. → Wi-Fi (or Advanced) → Wi-Fi for new firmware).
- Choose the 5GHz range (it is less crowded and faster, but worse passes through walls).
- Manually install the channel from the list below (depending on your router model).
36, 40, 44, 48 (lower range, better for range)
149, 153, 157, 161 (upper range, less interference)
100-140 (medium range, balance of speed and stability)-->
For the 2.4 GHz band, choose channels 1, 6 or 11 - they do not overlap with each other. Avoid automatic mode (Auto), as the router can choose an overloaded channel.
⚠️ Attention: On Xiaomi routers AX6000 and AX9000 In 5GHz settings, 160 MHz (channel width) is available, only if your devices support this standard (e.g. iPhone 12).+, Samsung Galaxy S21+), Otherwise, the speed may fall.
Once you change the channel, reconnect all the devices to the network and check the speed again. If there is no improvement, try another channel from the list.
3. Update router firmware
Outdated firmware can slow down the router, especially on new models like AX3600 or AX6000. Xiaomi regularly releases updates that fix bugs and improve performance.
To update the firmware:
- Open the Mi Wi-Fi app or web interface (192.168.31.1).
- Go to Settings. → Update of firmware (or System) → Firmware Upgrade).
- Click Check Updates. If a new version is available, install it.
If the automatic update does not work (relevant for Chinese versions of routers), download the firmware manually:
- 🌍 Official website: mi.com/support
- 📦 Firmware repository: 4PDA (Russian-speaking community)
⚠️ Attention: On routers with Chinese firmware (CN ROM) When updating via the web interface, the region may reset. To avoid problems, use only official firmware for your model and region.
On Xiaomi routers AX6000 and AX9000 after upgrading to firmware 1.2.0+ The Smart Channel Switch option is now available, and turn it on, and the router will automatically select the least loaded channel without losing communication.
4. Set up QoS (Quality of Service)
QoS allows you to prioritize traffic for certain devices or data types, for example, you can give the maximum speed of Smart. TV stream 4K or a game console, while limiting torrents on the computer.
To set up QoS on Xiaomi router:
- Go to the web interface (192.168.31.1) or the Mi Wi-Fi app.
- Go to Settings. → QoS (or Advanced) → Traffic Control).
- Turn on QoS and select the mode: 🎮 Gaming is a priority for online gaming (reduces ping). 📺 Video is a priority for streaming (YouTube, Netflix). 🖥️ Manually - specify the priority devices.
If you have chosen manual mode, add MAC-Device addresses that need more speed (find more speed) MAC can be in the device network settings).
On routers. AX3600 Extended QoS settings are available for traffic types, for example, you can limit the speed of the P2P (Torrents) or Social Networks, leaving the maximum for Videos and Games.
💡
If you have a Xiaomi router with Padavan or OpenWRT firmware, use the sqm scripts package for more flexible QoS management. This will reduce latency (ping) in online games to 5-10 ms.
5. Disable unnecessary functions and devices
Every device connected to the router and every function on consumes its resources, and if the router is overloaded, the speed drops for everyone.
- 🔌 Guest network – if not used, disable in Settings → Wi-Fi → Guest network.
- 📡 WPS — Unsafe feature that is better to disable in Settings → Security.
- 🔄 IPv6 — If your provider does not support IPv6, Turn it off in Settings → Network → IPv6.
- 📱 Remote control – Mi Wi-Fi Remote can slow down the router. → System system.
- 🖨️ DLNA/UPnP — If you do not use network printers or media servers, disable Settings. → Local area network.
Also check the list of connected devices (Settings) → Devices. If you see unfamiliar gadgets, turn them off (possibly neighbors have connected to your network); Xiaomi routers can limit the number of connected devices (maximum 64 for most models).
How to find “outside” devices on the network?
If you have a Mi Router router 4A Or another budget model, limit the number of devices connected to 20 to 30 simultaneously. These routers are not designed for large numbers of customers.
6.Change. DNS-server
DNS-servers convert domain names (e.g., google.com) into IP-addresses, if DNS The provider is slow, the sites will open with a delay, even if the Internet speed is high.
To change DNS on a Xiaomi router:
- Go to the web interface (192.168.31.1).
- Go to Settings. → Network → DNS (or advancedd → Network → DNS).
- Turn off automatic receipt DNS.
- Enter the addresses of alternatives DNS: 🌍 Google DNS: 8.8.8.8 and 8.8.4.4 🛡️ Cloudflare DNS: 1.1.1.1. and 1.0.0.1. 🇷🇺 Yandex DNS: 77.88.8.8 and 77.88.8.1
Save the settings and restart the router.
After shift. DNS Check the speed of opening sites. If there is no difference, return the settings to the machine or try another one. DNS.
⚠️ Note: Some Xiaomi firmware (especially Chinese) after manual change DNS The provider's local resources (e.g., personal account) may be lost. DNS third-slot.
7 Advanced settings: MTU, channel width, transmission power
If the basic methods didn’t work, try optimizing the router’s technical parameters, which affect the stability and speed of the connection, but require caution.
| Parameter | Recommended value | Where to change | For which models? |
|---|---|---|---|
| MTU | 1472 (if there are connection problems) | Settings → Network → WAN | All models. |
| Channel width (5 GHz) | 80 MHz (balance of speed and stability) | Settings → Wi-Fi → 5 GHz | AX3600, AX6000, AX9000 |
| Transmission power (Tx Power) | 100% (maximum range) | Settings → Wi-Fi → Additional | Mi Router 4A, Redmi Router AX5 |
| Beamforming | On (improving signal for compatible devices) | Settings → Wi-Fi → Additional | All models with 5 GHz |
For Xiaomi routers AX6000 and AX9000 customizable MU-MIMO (In Settings → Wi-Fi → Include it if you have many devices that support this standard (modern smartphones, laptops, TVs).
Warning: Do not set 160 MHz channel width on Mi Router 4A or Redmi Router AC2100 — These models don't support it stably, which will cause the connection to break down.
8. Alternative firmware: Padavan, OpenWRT
If standard settings don't work, and the router slows down even after a reset, consider alternative firmware. They offer more optimization options, but require technical skills.
Popular firmware for Xiaomi routers:
- 📦 Padavan is the most stable firmware with advanced QoS settings, VPN It supports Mi Router and monitoring. 4A, 3G/3Gv2, 3C, R3P.
- 🐧 OpenWRT is open firmware with flexible configuration, but it's harder to install. AX3600, AX6000 (assemblies).
- 🔄 Stock ROM (modified) – modified official firmware with corrected bugs (for example, from Xiaomi EU).
Advantages of alternative firmware:
- 📈 More accurate QoS setting (e.g., port priority or IP).
- 🔒 WireGuard and OpenVPN support (for secure connection).
- 📊 Detailed statistics of traffic by device.
- 🔄 Ability to disable unnecessary services (e.g. MiWiFi) ROM background).
⚠️ Warning: Installing an unofficial firmware resets the warranty and can lead to a router "bricking" (if you interrupt the upgrade process). → System system → Backup.
Installation instructions:
- 📖 Padavan for Xiaomi (4PDA)
- 📖 OpenWRT for the AX3600 (quid)
💡
Alternative firmware is only relevant if you have exhausted all standard optimization methods. For most users, it is enough to set up the regular firmware correctly.
