How to speed up Wi-Fi on Xiaomi: an expert guide

Slow internet on a smartphone is a problem that almost every owner of Xiaomi, Redmi or POCO devices faces. Owners often notice that even with a powerful plan, page loading is delayed and video content is constantly buffered. This is not always the fault of the provider, often the reason lies in the software limitations of the MIUI or HyperOS shell.

There are many hidden settings that may not be optimized by default to work in congested air channels. The right configuration of the communication module can work wonders even if you are far from the router. In this article, we will discuss the technical aspects that will help you get the most out of your wireless connection.

Before you get to the tricky side of things, you need to rule out trivial factors like overheating of the module or outdated router firmware. Xiaomi Wi-Fi speed depends on the version of the wireless drivers built into the system software. If your device has not been updated for a long time, the chances of low performance increase many times over.

Diagnostics of current connection and analysis of interference

The first step is always to make a good diagnosis. Don't wonder why the Internet is bad when you can get accurate numbers. Use built-in system tools or third-party utilities to analyze signal quality. Xiaomi devices have a hidden engineering menu, but you'll need standard tools to start with.

Pay attention to the frequency at which your smartphone operates. Most users sit at an overloaded 2.4GHz frequency, even though their routers and phones have long supported 5GHz. Switching to a higher frequency is the easiest way to speed up Wi-Fi without overpaying for a tariff.

⚠️ Attention: 5GHz frequency has less penetration through walls. If the router is in another room behind two concrete partitions, the speed at 5GHz may be lower than at 2.4GHz due to packet loss.

For deep channel analysis, we recommend using applications like Wi-Fi Analyzer, which will show how busy your neighbor's routers are, and if your channel crosses a dozen other channels, the speed will drop even with a perfect signal.

Configure DNS and network settings in Android

Often the bottleneck is not the data transfer speed, but the response speed of domain name servers. DNS-Your ISP's servers may be slow or incorrect in processing requests, and changing these parameters in your smartphone settings is one of the most effective measures.

To change your settings, go to Settings → Wi-Fi. Click on the arrow or your current network name to reveal additional settings. Find the IP Settings and switch it from DHCP to Static. Here you will need to manually prescribe DNS addresses.

In DNS 1 and DNS 2, enter the addresses of public servers. The fastest and most stable servers are those from Google and Cloudflare. For example, for Google it is 8.8.8.8 and 8.8.4.4, and for Cloudflare it is 1.1.1.1 and 1.0.0.1. Once saved, the phone may require a reconnection to the network.

• 🚀 Google DNS: Classic solution with high response speed around the world.
• 🛡️ Cloudflare DNS: privacy-focused and often shows the best ping component.
• ⚙️ OpenDNS: Offers flexible filtering settings, but may be a bit slower in some regions.

Don’t forget that static is IP-You need to specify the address correctly so that there is no conflict of addresses on the local network. Usually, you just need to change the last digits of the gateway address or leave the proposed system, changing only the last digits of the gateway address. DNS.

💡

If after changing the DNS pages began to load faster, but the video slows down – the problem may be in routing the traffic provider, not in the speed of resolving domains.

Using Developer Mode to Optimize

Deep inside the Android operating system that runs MIUI, there are debugging tools that can affect the way network interfaces work, and they're closed by default so that inexperienced users don't harm the system, but we know how to activate them.

To enter Developer Mode, you need to quickly click 7 times on the MIUI Version in About Phone. Once the Notification "You Become a Developer" appears, a new menu will open in the Additional or Advanced Settings section. We are interested in the block associated with the network.

Find Aggressive Wi-Fi Switching to Mobile. If it's on, the phone can constantly jump between Wi-Fi and 4G/5G, which creates the illusion of slow Internet. Disable this feature if the Wi-Fi signal is stable but weak. It's also worth checking the Scan throttling Wi-Fi settings - turning them off can improve network search but increase battery consumption.

Be careful when changing parameters labeled "experimental" that can cause the communication module to function unstable after the device is restarted, and if you are unsure of the specific option, it is best to leave it as default.

Resetting network settings and removing profiles

Accumulation of errors in network configuration files is a common cause of problems after updating firmware or prolonged operation. The phone can "remember" old security settings or incorrect encryption keys, which slows down the installation of handshake protocol with the router.

The most radical but effective method is to completely reset your network settings. This action will delete all stored Wi-Fi passwords, Bluetooth settings, and mobile network (APN) settings. To complete, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks, and Bluetooth.

Once reset, the device will restart and you will have to re-enter your router’s password, which clears the cache of network drivers and often resolves the problem when the phone “sees” the network but does not connect or connects with restricted access.

⚠️ Before resetting, make sure you remember your Wi-Fi password and PIN-code SIM-Cards (if installed) as they will be deleted from the phone's memory.

It is also recommended to remove old, unused network profiles from the list of saved ones.If a phone tries to automatically connect to a weak signal from a neighbor router of the same name (SSID), this will interfere with the main work.

The Impact of Energy Saving on Internet Speed

Xiaomi’s battery optimization systems are known for being aggressive, and to extend the battery life, the smartphone can limit the background activity of applications and, more importantly, reduce the power of the Wi-Fi module or turn it off when the screen is locked.

Check battery settings for mission-critical applications. If the messenger or navigator can’t work in the background due to energy savings, it can create a feeling of “laying” the Internet. Go to Settings → Battery and performance and select No Limits mode for the desired programs.

In addition, the Battery section has a function called "Sleep in Standby." If it is activated, Wi-Fi can turn off when the screen goes out. For maximum Internet speed, it is recommended to turn off super-saving modes when you are actively using the network.

• 🔋 Flight mode: Short-term flight mode switching on and off helps you reconnect to the nearest tower or router.
• 📉 Background Processes: Limiting Background Activity May Reduce App Updates’ Download Speed.
• ⚡ Optimization MIUI: Embedded optimization sometimes mistakenly “strangles” the network stack, try to disable it in the developer settings.

Frequent Questions and Additional Solutions (FAQ)

Even after all the recommendations are followed, there may be nuances that depend on the particular router model or Android version, and here are the answers to the questions that users often have when trying to speed up the connection.

An integrated approach: a combination of DNS change, 5 GHz switching and competent energy saving settings gives the best result.
