How to improve the Internet on Xiaomi: from Wi-Fi to Wi-Fi 4G/5G

Slow internet on Xiaomi smartphone is one of the most common problems faced by users of Redmi devices, POCO Even on flagship models like Xiaomi 14 Ultra or POCO F6 Pro connection speeds can sag due to software limitations, incorrect settings or hardware features. In this article, we will examine all possible causes of poor Internet, from banal errors in settings to hidden functions. MIUI, which interfere with a stable connection.

It's important to understand that the problem isn't always with the phone itself, sometimes the router, the ISP, or even physical obstacles (walls, furniture) are at fault, but in 70 percent of cases, you can increase speed without buying new hardware -- just fine-tune your smartphone. We tested all the methods on the devices with MIUI 14 and HyperOS, so the instructions are relevant for the 2020-2026 models.

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

Before optimizing the settings, you need to understand what is slowing down the connection, and here are the key signs and their possible causes:

• 📶 Wi-Fi is working, but the speed is low. → Problem with router, transmission channel or phone settings.
• 📡 Mobile Internet (4G/5G) unstable → weak signal operator, incorrect APN limiting MIUI.
• 🔄 The Internet is coming and going. → conflict IP, mistake DNS background.
• 🚫 Websites are not open, but messengers are working → Traffic blocking by the operator or failures in MIUI Optimization.

For accurate diagnosis:

1. Check the speed via Speedtest or FAST.com.
2. Compare results on other devices (laptop, tablet) on the same network.
3. Switch from Wi-Fi to mobile data and vice versa – if the problem persists, the phone is to blame.

⚠️ Note: If all devices are slow, the problem is with the router or provider. In this case, Xiaomi optimization will not help - you need to call in support of the ISP.

2. Optimizing Wi-Fi on Xiaomi: Hidden Settings MIUI

MIUI HyperOS and HyperOS have a number of hidden features that can both improve and degrade Wi-Fi speeds:

Selecting the right range (2.4 GHz vs 5 GHz)

Most routers support two bands:

• 📡 2.4 GHz - longer range, but lower speed and higher channel load (interfering with neighboring networks).
• 🚀 5 GHz - faster speed, but worse through walls. Optimal for streaming video and gaming.

How to switch to Xiaomi:

1. Open the Settings. → Wi-Fi.
2. Click on the name of your network → Change the network.

Turn off Wi-Fi Assistant

Set up static. IP (optionally)

Update router firmware

Reboot your phone and router-->

3. Accelerating the Mobile Internet (4G/5G)

If mobile internet on Xiaomi is slow, the problem may be:

• 📶 Incorrect settings APN (point-of-access).
• 🔄 Restrictions MIUI background traffic.
• 📡 Weak signal (especially in basements or outside the city).

3.1 Verification and discharge APN

APN (Access Point Name is the address that connects the phone to the operator's network, and if it gets lost, the Internet will run slowly or not at all.

How to drop APN Xiaomi:

→ SIM-maps and mobile networks → [Your SIM] → Access Points (APN) → ⋮ → Reset to default values

If the reset didn't help, add APN manually (options can be found on your operator's website:

• Name: MTS
• APN: internet.mts.ru
• Type of authentication: PAP

3.2. Enabling VoLTE and VoNR (for the purpose of 4G/5G)

VoLTE technologies (voice on the 4G) and VoNR (voice on) 5G) Not only do they improve the quality of calls, but they also stabilize the speed of the Internet during a conversation:

Settings → SIM- Maps and Mobile Networks → [Your SIM] → Insert VoLTE/VoNR

⚠️ Note: Some Xiaomi models (e.g. Redmi Note 10) may not have VoNR option even if the phone supports the device. 5G. This is a firmware restriction - check for updates.

3.3. disable background traffic restriction

MIUI By default, it limits background data consumption to save traffic, which can inhibit content loading on instant messengers or social media, to remove the restriction:

Settings → Connections and Sharing → Data Use → Data Transfer → ⋮ → Limit background traffic → Disable

💡

If the mobile Internet is lost after the update MIUI, Try to manually select the operator network in the settings (Settings) → Mobile network → Network operators → Manual search).

4. Update firmware and reset network settings

Often, slow internet on Xiaomi is associated with outdated firmware or network settings.

If you live in a low-coating area, an external antenna (e.g., a remote area, 4G LTE It can amplify the signal, and it connects through the adapter to the connector. SMA (If it is on your model).

Replacement SIM-maps on nano-SIM new model

Old ones. SIM-Cards (especially micro-SIM cut-offs) may not make good contact with the slot, causing connection breaks. Replace it with a new nano-SIM in the operator's cabin.

💡

If the Internet is completely lost after the phone falls, the antenna module may break, in which case only repairs at the service center will help.

Alternative solutions: VPN proxy

Sometimes operators or providers artificially limit speed (trottling). VPN proxy:

Adjustment VPN circumvention

VPN encrypts traffic and hides it from the provider, which can increase speed:

• 🔒 ProtonVPN (free, no logs).
• 🚀 Warp by Cloudflare (optimized for speed).
• 🌍 NordVPN (paid, but with servers in Russia).

How to connect VPN Xiaomi:

Settings → Connections and Sharing → VPN → Add VPN → Select Type (PPTP/L2TP/IPSec)

7.2 Use. DNS from Google or Cloudflare

Replacement DNS-ISPs can speed up the opening of sites. Change DNS wifi-based:
