How to speed up mobile Internet on Xiaomi Redmi Note 8 Pro: a complete guide

The Xiaomi Redmi Note 8 Pro is still one of the most popular smartphones among users who value value value for money, but with the release of new communication standards (5G, VoLTE) and firmware updates, many owners are faced with the problem that mobile Internet is slower than on new devices, the reasons may lie in both the software settings and hardware limitations of the model.

In this article, we’ll look at 12 working methods to increase mobile internet speed on the Redmi Note 8 Pro, from basic settings to hidden engineering menu features. All of them have been tested on current versions of MIUI 14 and Android 12, but they’ll work for older firmware, and Importantly, some tricks require super-user rights, but most methods are available without them.

Before you start setting up, check your current Internet speed through services like Speedtest or FAST.com, write down the results so you can objectively estimate the increase after optimization, and if the speed is below 10 Mbps under good coverage, the problem definitely needs to be solved.

1. Optimization of mobile network settings

The first thing to check is the mode of operation of the mobile network. By default, the Redmi Note 8 Pro may use a not the fastest standard, especially if you are not using the most advanced standard. SIM-The card is old or the operator hasn't updated the service profile:

• 📶 Switch the network mode to 4G (LTE): Go to Settings. → SIM-maps and mobile networks → [choose SIM] → Network type and install 4G (a) If available, if recommended; 4G+ or LTE+ — Choose him.
• 🔄 Enable VoLTE: This feature allows you to call LTE without the Internet speed drop. → SIM-maps and mobile networks → [choose SIM] → Voice calls → turn on VoLTE.
• 🌐 Turn off automatic network selection: sometimes the smartphone clings to a weak tower. Manually select the operator in Settings → SIM-map → Networking.

If the speed has not increased after these manipulations, the problem may be in the APN-Each operator has its own access parameters, which can be found on the official website (Internet settings section). APN It should look like this:

⚠️ Attention: After the change APN If the internet is gone, return the standard settings or contact the operator, maybe there are restrictions on your tariff.

2. Update of firmware and modem software

The Redmi Note 8 Pro has received several major MIUI updates, but not all of them are optimized for mobile Internet. Paradox: sometimes the old firmware version is faster than the new one because of bugs in the modem drivers.

1. Check out the current version of MIUI: Settings → About Phone → MIUI Version. The latest stable version for the Redmi Note 8 Pro is MIUI 14.0.4 (Android 12).
2. Update the firmware: if the version is outdated, download the update through Settings → System Update.
3. Reverse to the old firmware (if the speed dropped after the update): this requires an unlocked bootloader and the Mi Flash Tool.

Critical information: On Xiaomi forums, users note that the MIUI 12.5.7 firmware (Android 11) shows the best LTE speed on the Redmi Note 8 Pro compared to MIUI 13/14. If the Internet is more important than new features, consider rollback.

You also need to update your modem software, which is done through the engineering menu:

#4636## → Phone information → Update modem

3. Reset network settings and cache

Over time, network connection errors accumulate in the system, and resetting network settings often helps to return the original speed:

• 🔄 Go to Settings. → System and device → Resetting settings → Resetting Wi-Fi, Mobile Network and Bluetooth.
• 🧹 Clear the cache of system applications: Settings → Annexes → Application management → [three-point] → Show system-based → Settings → Clear the cache.
• 📱 Restart your phone in Safe Mode (click the power button) → "Safe mode") and check the speed. If it's up, it's third-party software.

⚠️ Warning: After a network reset, you'll have to re-enter your Wi-Fi passwords and configure your Bluetooth devices. If you're using two-factor authentication (SMS), make sure you have backup codes.

4. Optimization of work SIM-map

The quality of communication depends on the physical condition. SIM-The card and the slot:

• 🔧 Clear your contacts. SIM-maps: wipe them with a soft eraser or an alcohol wipe. Contact oxidation is a common cause of a bad signal.
• 🔄 Change the slot. SIM-If you have two cards: SIM, try to move the main card to another slot (on the Redmi Note 8 Pro, the first slot usually catches the network better).
• 🆕 Replace. SIM-Older cards (especially Mini-SIM) may not support modern communication standards.

If you use two of them SIM-Redmi Note 8 Pro supports Dual 4G, But only one card can work in the LTE-To check which card is active:

Settings → SIM- Maps and Mobile Networks → [select SIM] → Enable Mobile Data

💡

If you travel frequently, buy an eSIM-enabled SIM card (such as Tele2 or MTS) that doesn’t wear out physically and allows you to quickly switch between operators.

5. Setting up the engineering menu (for advanced)

The hidden engineering menu (MTK Engineering Mode) allows you to fine-tune the modem settings. Redmi Note 8 Pro is built on a Mediatek Helio G90T chip, so the menu is available by code:

##36446337##

In the menu, go to MTK Settings → BandMode.

• 📡 Enable all supported frequencies LTE (By default, some may be disabled).
• 🔍 Forced to choose a range (such as Band 3 or Band 7) if you know which works best in your area.
• 🔄 Reset the modem settings to factory (Restore Default option).

⚠️ Warning: Incorrect settings in the engineering menu can lead to total network loss. Before changing, write down the current settings or take screenshots. If the Internet is lost after the changes, reset using ##4636## → Phone Information → Set Preferred Network Type → LTE only.

Hardware acceleration methods

If the software methods didn't work, the problem could be the hardware.

• 📶 antenna Wi-Fi/4G: on the Redmi Note 8 Pro antennas are located at the bottom of the case, and if you use a case with metal inserts or hold the phone in your hand, covering the antenna, the signal will be weaker.
• 🔋 Battery status: If the battery is worn out (capacity below 70%), the smartphone may limit performance, including modem speed. → Battery → Battery status.
• 🔌 Motherboard problems: If the Internet speed dropped dramatically after falling or getting moisture, it could be a microcrack on the board.

For the hardware test:

1. Put it in. SIM-Card to another phone and check the speed.
2. Try another one. SIM-Card (another operator) in your Redmi Note 8 Pro.
3. If the speed is low on all devices, the operator has a problem, unless your smartphone is the fault of the iron.

💡

If, after the replacement, SIM-The speed of the card and resetting the settings has not increased, and other devices work normally - a malfunction in the communication module Redmi Note 8 Pro. Repair will cost 1,500-3000 ₽ (replacement of the antenna block or soldering of the modem chip).

7. Alternative methods: VPN and proxy

Sometimes operators limit the speed of certain services (such as torrents or streaming), bypassing this by:

• 🔒 VPN: Free services like ProtonVPN or Warp (Cloudflare) can increase speed by optimizing routes. Install from Google Play and turn it on before the test.
• 🌍 DNS-servers: replace DNS Operator on 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google). → Connections → Private DNS.
• 📡 Proxies: Some operators (e.g. Yota) allow proxying to accelerate.

Important: VPN can both increase and decrease speeds, depending on the load of the servers.

- Turn off the VPN and measure the speed.


- Turn on the VPN and repeat the test.




- Compare the results.

💡

For streaming videos (YouTube, Twitch), it is better to use VPNs with servers in Europe (for example, the Netherlands or Germany), which are usually less loaded than Russian ones.
