You're giving out the Internet from a Xiaomi smartphone, but your devices are constantly shutting down, the speed drops to 1-2 Mbps, and the range does not exceed 3 meters? The problem is not your phone - 90% of the time it is due to incorrect settings or external interference. Even the budget models of Redmi and POCO are able to distribute Wi-Fi at the level of specialized routers, if you know a few technical nuances.
In this article, practical methods for improving the access point that work on all Xiaomi smartphones (from Redmi Note 10 to Xiaomi 14 Ultra), we will analyze both software tricks (hidden MIUI settings, choice of Wi-Fi channel) and hardware solutions (external antennas, correct position of the phone), and pay special attention to the unique problem of Xiaomi smartphones – automatic limiting the speed of the transfer when the processor is heated, which is not written in the standard instructions.
Basic conditions check: why the access point is slowing down
Before digging into the settings, rule out the obvious reasons for poor handouts. Most often, users miss three key points:
- 📶 Weak mobile signal. If you have a mobile phone 1-2 division 4G/LTE, Your phone can't physically give away what it doesn't get. Check your mobile Internet speed without giving away through Speedtest.
- 🔋 Energy saving regime. MIUI aggressively restricts background processes, including the Wi-Fi module. → Battery → Energy saving regime.
- 📱 CPU overheating, above 45.°C Xiaomi forcibly reduces the power of the Wi-Fi module. CPU Monitor for temperature control.
If one of these is relevant, then you don't need to set up the hotspot any further, so you can first address the root cause: change the location (to improve the cellular signal), cool the phone, or turn off the power saving.
2. Optimal settings of the access point in MIUI
Xiaomi's standard Wi-Fi options are far from perfect. Even the latest versions of MIUI 14/15 have universal values that don't take into account your surroundings by default.
- Frequency range. Go to Settings. → Access point → Access point settings and select: 🔄 2.4 GHz – better penetrates walls, but is subject to interference from other networks. ⚡ 5 GHz – higher speed (up to 866 Mbps), but shorter range and sensitivity to obstacles. 🎯 Auto – The phone chooses the range (recommended for most users).
Channel width
40 MHz
2.4 GHz
80 MHz
5 GHz
Security
WPA2-PSK
WPA3-PSK
WEP
After the changes, restart the phone - this will reset the network settings cache and apply the new parameters correctly.
Select the 5 GHz band (if devices support it)|Set the channel width of 80 MHz|Turn off the power saving mode|Turn on WPA3-PSK|Reboot your phone after the changes-->
3. Hidden settings: how to get around the limitations of MIUI
Xiaomi hides some of the access point parameters to make the interface easier, but these parameters are critical to the stability of the distribution.
- Enter the code in the phone app: ##4636## This will open the engineering menu.
- Go to the Wi-Fi information section.
- Click on the three dots in the upper right corner and select the Wi-Fi frequency band.
- Set 5 GHz (if your phone supports this range).
For USB-Xiaomi may need to include debugging on the USB (Settings → The phone. → Version. MIUI — Press 7 times, then Settings → Additionally. → For developers → Debugging by USB).
💡
USB-The distribution is the most stable way, but it only works when connected to a single device. For multiple gadgets, it is better to use Wi-Fi with an external antenna.
7. Frequent mistakes and how to avoid them
Even after you set it up properly, users make mistakes that nullify their efforts, and here are the most common ones:
- A MIUI limits the password length of the access point to 8-63 characters, but passwords longer than 20 characters can cause connection errors on older devices.
- Use of special symbols in SSID. Name of the network (SSID) It should not contain Cyrillic, spaces or symbols such as!@#$. Optimal format: Xiaomi_AP_5G.
- Simultaneous 2.4 and 5 GHz distribution. Some MIUI firmware allows you to turn both bands on simultaneously, but this creates interference and reduces speed by 30-40%.
- Ignoring updates. Newer versions of MIUI fix Wi-Fi distribution bugs. Check firmware relevance in Settings → About Phone → System Update.
If the access point is still unstable after all the manipulations, try resetting the network settings (Settings → System → Resetting → Resetting Wi-Fi, mobile network and Bluetooth settings) This will delete all the saved networks and reset the settings to factory ones, which often resolves software conflicts.
