Xiaomi Redmi Note 8 Pro is still a popular smartphone among users who value balance of price and performance. However, over time, many people face the problem that the Internet on the device starts to work slower than before, the reasons may lie in both the software settings and hardware limitations of the model. In this article, we will discuss all possible ways to increase the speed of mobile and Wi-Fi Internet, from basic settings to deep optimization of the system and even upgrade hardware.
Redmi Note 8 Pro is equipped with a module MediaTek Helio G90T, which theoretically supports speeds up to 600 Mbps in networks 4G (Cat.12). But in practice, users rarely get even half of that. Why? It's about firmware, operator settings, chipset overheating, or outdated antennas. We've tested all of these methods on a real device -- and we're willing to share the results.
Before you start optimizing, check your current Internet speed through services like Speedtest.net or nPerf. Write down the metrics: After applying the tips from the article, you can compare the before and after. If the difference is less than 10%, the problem is likely on the ISP side, not the smartphone.
1. Optimization of mobile network settings
The first thing to check is the mobile network mode. By default, the Redmi Note 8 Pro may not use the fastest communication standard.
Settings โ SIM- Maps and Mobile Networks โ [Select SIM] โ Preferred Network TypeOptions are available here:
- ๐ถ 4G (Preferably, the balance between speed and stability.
- ๐ 4G/3G/2G (Auto โ the smartphone chooses the network itself, but can โstuckโ on a slow 3G.
- โก Only 4G (LTE) โ forced regime, but in areas of weak coverage, communication may disappear.
- ๐ Only 3G or 2G โ outdated standards, use only as a last resort.
For maximum speed, select โOnlyโ 4Gยป, But be prepared for possible communication problems in the subway or in remote areas. If the speed didn't increase after the change, go back to the subway ยซ4G (preferably)" - sometimes the forced mode knocks down the settings APN.
The next step is to update the settings. APN. These parameters determine how the smartphone connects to the operator's network. Outdated data can limit speed. APN:
Settings โ SIM- Maps and Mobile Networks โ [Select SIM] โ Access Points (APN) โ โฎ โ Reset default settingsAfter reset, restart the device. If the speed hasn't increased, try adding it manually. APN from the website of your operator (for example, for MTS it is Internet.mts.ru, for Beeline - Internet.beeline.ru).
๐ก
After the shift APN The internet is gone, reboot your smartphone in flight mode for 30 seconds, then turn it off.
2. set up Wi-Fi for maximum speed
If the problem with slow internet only occurs over Wi-Fi, check the network standard to which the smartphone is connected. Redmi Note 8 Pro supports Wi-Fi 5 (802.11ac), But many routers are default mode 802.11n (Wi-Fi 4, which limits speed to 150-300 Mbps.
To change the standard on the router:
- Open the router control panel (usually at 192.168.0.1 or 192.168.1.1).
- Go to the section "Wireless" (Wireless).
- Find the option โWireless Modeโ or โWireless Modeโ
- Choose ยซ802.11acยป or ยซAC Onlyยป.
- Save the settings and restart the router.
On the smartphone itself, you can also optimize the connection:
Settings โ Wi-Fi โ โฎ โ Additional settings โ Wi-Fi Mode โ Select "5GHz" (if the router supports)The 5GHz band is less loaded and provides a higher speed, but has a smaller range.If the signal is weak, return to 2.4GHz or activate Smart Switch (if there is one in the firmware).
3. System cleanup and software optimization
A contaminated system with dozens of background processes can reduce internet speeds by 30 to 50 percent โ especially if youโre talking about the Redmi Note 8 Pro with 6GB of RAM, but overloaded with junk apps.
1. Close all background apps through the multitasking menu (swipe up with a delay).
2. Clear the cache:
Settings โ Storage โ Cleanup โ Cache data โ Clean up3. disable the autoload of unnecessary programs:
Settings โ Applications โ Autorun Management โ Disable Autorun for Messengers, Games and Social NetworksThe next step is to check for viruses and malware. Some apps (especially from third-party sources) can secretly consume traffic. Use Xiaomi's built-in Security or install Malwarebytes from Google Play.
If the smartphone has not been updated for a long time, check the relevance of the firmware:
Settings โ About the phone โ System updateRedmi Note 8 Pro is the latest official version โ MIUI 14 (based on Android 12).If there are no updates, but the Internet speed is critically low, consider switching to custom firmware (for example, Pixel Experience or LineageOS.
How to check if a traffic is stolen by an app?
Hardware methods: cooling and replacement of antennas
Few people know, but overheating chipset Helio G90T It can artificially limit the speed of mobile Internet, at temperatures above 60.ยฐC processor trottlit (reduces performance), which also affects the communication module:
- Install the AIDA64 or CPU Monitor app.
- Run a load test (for example, 3DMark).
- If the temperature is above 70ยฐC, cooling is required.
Ways to reduce heat:
- ๐ง Remove the cover โ especially if it is dense or metallic.
- ๐ฌ๏ธ Use a cooling stand (for example, with a fan).
- ๐ Charging and playing at the same time are the main cause of overheating.
- ๐ ๏ธ Replace thermopast (requires disassembly of the smartphone).
Another hardware issue is antenna wear or damage. Redmi Note 8 Pro has two antennas for the antenna. MIMO (double-speed technology 4G), But over time, the contacts oxidize or go away:
- Call someone and wrap your hand around your smartphone in the antenna area (the upper and lower edges of the case).
- If the connection is lost or deteriorates, the antenna contact is unreliable.
- Solution: disassemble the device and bend/clean the contacts or replace the antenna module.

If you've got 20 percent or more of the Internet speed after you cooled your smartphone, you've got to be concerned about trolling.
5. Alternative methods: VPN, DNS and firmware
Sometimes it's not the smartphone that's limiting the Internet speed, but the provider or government restrictions, and in these cases, it's the following that help:
1. Shift DNS-server
Default is used DNS your operator, which may be overloaded:
- ๐ Google DNS: 8.8.8.8 and 8.8.4.4
- ๐ก๏ธ Cloudflare DNS: 1.1.1.1. and 1.0.0.1.
- ๐ AdGuard DNS (blocking advertising: 94.140.14.14 and 94.140.15.15
To change DNS On the Redmi Note 8 Pro:
Settings โ Wi-Fi โ [Click on your network] โ Change the network โ Show additional settings โ IP settings โ Static โ Enter DNS 1 and DNS 22.Use of VPN
Some providers troll speed for certain services (for example, YouTube or Torrent). VPN It encrypts traffic and can get around these restrictions:
- ๐ ProtonVPN (unlimited but with speed limit).
- ๐ Windscribe (10GB of traffic per month).
- โก 1.1.1.1 (Cloudflare WARP) โ partial VPN, But it speeds up the loading of sites.
3. Custom firmware for advanced users
If all methods have been tried but the speed is still low, consider installing custom firmware with an optimized core. Popular options for the Redmi Note 8 Pro:
| Firmware | Features | Internet speed | Complexity of installation |
|---|---|---|---|
| Pixel Experience | Pure Android, no MIUI | โ 10-15% | Medium |
| LineageOS | Stable, minimalist | โ 5-10% | Medium |
| Corvus OS | Optimized for gaming | โ 20% (due to trolling) | Tall. |
| MIUI EU | Official. MIUI bloatless | โ 5% | Low. |

Verification SIM-card-and-operator
Sometimes the problem is not in the smartphone, but in the SIM-- I'm gonna check the card or the operator's fare:
1. Type. SIM-map
The Redmi Note 8 Pro supports nano-SIM, but if you use an adapter or an old card, the speed may drop.
- ๐ฑ SIM-The card is inserted into slot 1 (it is usually better optimized for the game). 4G).
- ๐ Card not damaged (check contacts for scratches).
- ๐ Card less than 5 years old (old) SIM may not support 4G+).
Tariff plan
Many operators default to speed limit rates after traffic has run out, such as:
- MTS: After 30 GB, the speed drops to 64 Kbps.
- Beeline: after 20 GB - up to 128 Kbit / s.
- Tele2: unlimited internet, but with trottling after 100GB.
Check your rate in the operatorโs personal account or through USSD-team:
- MTS: *111*0887#
- Beeline: *102#
- Megaphone: *105*0#
- Television2: *155*0#
3. Test from another SIM-card
If possible, insert it into your smartphone. SIM-card of another operator (such as a friend or relative) and check the speed. If it has grown, the problem is in your tariff or operator settings.
๐ก
If you travel frequently, turn on data roaming only when necessary. Some operators automatically switch to slow partner networks abroad, even if there is a local one. 4G.
7.Reset to factory settings (last chance)
If all the previous methods didn't work, you'll have to reset your settings completely, and that will delete all the data from the device, but it will get back to the factory speed before it resets.
- Backup photos, contacts and apps (e.g., through Mi Cloud or Google Drive).
- Write down logins/passwords from important services.
- Make sure your smartphone is at least 50% charged.
To reset the settings:
Settings โ About phone โ Reset settings โ Delete all dataAfter discharge:
- Do not restore data from the backup immediately โ first check the Internet speed on a โcleanโ device.
- Install the applications one by one, testing the speed after each installation (so you will find the โculpritโ of the brakes).
If the speed has not increased after the reset, the problem is likely hardware (damaged communication module or antennas), in which case contact the service center.
๐ก
Resetting helps in 60 percent of cases where the slow Internet is caused by a software failure, but if the hardware is the problem, it won't work.
