How to improve the quality of the Internet on the Xiaomi phone: from basic settings to hidden features MIUI

Weak internet on Xiaomi is a problem that every third user faces, from pages to pages loaded for eternity, to videos in the future. 1080p It slows down all the time, and the connection suddenly breaks down, and the reasons can be in the settings of the phone itself, as well as external factors, from an overloaded router to the limitations of the mobile operator. In this article, we’ll explore all the possible ways to improve the speed and stability of the Internet on Redmi devices, POCO Mi – from banal reboot to hidden firmware functions MIUI.

It is important to understand that there is no universal solution: if you have Xiaomi 12T Pro with Wi-Fi 6, and the router gives you a maximum of Wi-Fi 4, so even the perfect settings on the phone won't give you any speed gain. So we start by diagnosing the problem, then optimizing the settings. MIUI, And then we end up with hardware constraints and alternatives, and we're ready to bring back lightning-fast Internet to our smartphone?

1. Diagnostics of the problem: why is the Internet slowing down?

Before you set up anything, you need to understand the root of the evil. Bad Internet on Xiaomi can be caused by:

• 📶 Weak signal. Wi-Fi/Cellular network – the phone is far from the router or in the area of poor coverage 4G/5G.
• 🔄 Network congestion – too many devices are connected to a single router or the mobile operator limits speed.
• ⚙️ Wrong settings. MIUI — Traffic saving mode is activated, activated VPN or limited background internet for applications.
• 📱 Iron problems - damaged module Wi-Fi/4G, outdated communication chip (for example, in budget Redmi) 9A).
• 🔗 Router conflicts – incompatibility of Wi-Fi standards or incorrect settings DHCP.

How do you check quickly? Use the built-in speed test in the MIUI:

1. Open the Settings. → Connections and sharing → Mobile network (or Wi-Fi).
2. Tap the name of your network (mobile or Wi-Fi).
3. Select the Speed Test – the phone will measure ping, download speed and recoil.

If you're running below 10 Mbps on Wi-Fi or 5 Mbps on mobile, there's a problem. Compare the results to other devices on the same network. If you're using a laptop or another phone, it's your Xiaomi who's at fault. If it's bad everywhere, look for the reason in the router or the carrier's tariff.
