The problem of low wireless connection speed on devices of the line Xiaomi And Redmi This is quite common, especially with increasing traffic demands. Users often encounter a situation where their data plan allows for hundreds of megabits, but the actual speed barely reaches 10-20 Mbps. This can be caused by software limitations of the operating system. MIUI or HyperOS, as well as physical obstacles or air congestion.
In this article, we'll cover not only the basic steps for rebooting, but also delve into the engineering menu, DNS settings, and frequency ranges. You'll learn how to select the right channels and understand the differences between data transfer standards. Properly configuring your router and smartphone together can work wonders, turning slow internet into a fast data stream.
Before moving on to complex manipulations, it's worth eliminating trivial but critical factors. Often, the problem lies in outdated firmware or the device's physical location. Let's look at the first optimization steps that every owner should take.
Basic diagnostics and reset of network settings
The first thing you need to do is make sure the problem is local and not related to your ISP. Check the speed on other devices. If the internet is flying on your laptop or tablet, but not on Xiaomi If it barely loads, it's probably a phone configuration issue. In such cases, the most effective solution is a full network reset.
To perform this procedure, go to the menu Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and BluetoothBy clicking the "Reset Settings" button, you will delete all saved passwords and Bluetooth device configurations. This action will clear any software errors that may have accumulated over time.
After the reset, your smartphone will reboot, and you'll need to re-enter your Wi-Fi network password. Don't skip this step, as it often resolves issues with stuck wireless module drivers.
⚠️ Attention: After resetting your network settings, you'll need to re-sign in to all apps and smart devices that used Bluetooth or Wi-Fi for pairing.
It's also important to check whether you have a data saving or power saving mode enabled that aggressively limits background activity. In the "Security" section, find "Battery" and ensure that your mode doesn't have strict limits on background processes.
☑️ Connection diagnostics
Working with frequency ranges: 2.4 GHz vs. 5 GHz
One of the main reasons for slow speeds is operating in the congested 2.4 GHz band. This frequency spectrum is used not only by Wi-Fi routers, but also by microwave ovens, Bluetooth headsets, and neighbors' networks. In apartment buildings, the airwaves here are literally clogged with noise, leading to packet loss and reduced throughput.
Modern smartphones Xiaomi support dual-band standard 802.11ac and newer. Switching to the 5 GHz frequency significantly increases channel throughput. The signal at this frequency has a harder time penetrating walls, but within a single room or apartment, the speed will be maximum.
To switch, look for your router's name in the list of available networks, followed by "5G" or something similar. If you don't see such a network, you'll need to go to the router settings (usually at 192.168.0.1 or 192.168.1.1) and enable broadcasting in the second band.
Some router models combine both bands into a single network with a single name (Smart Connect technology). In this case, the phone automatically decides which one to connect to. If it persistently chooses the slower 2.4 GHz band, it's best to separate the networks in the router settings by giving them different names, for example, HomeWiFi And HomeWiFi_5G.
- 📡 2.4 GHz: Long range signal, but low speed and a lot of interference.
- 🚀 5 GHz: High speed, less interference, but worse wall penetration.
- 🏠 Recommendation: Use 5GHz near your router for streaming and gaming.
Why is 5GHz faster?
The 5 GHz band has more available channels and a wider bandwidth. If 2.4 GHz is comparable to a narrow, single-lane road in the city center, then 5 GHz is like a wide highway outside the city. Even with the same signal strength, data transfer rates will be higher at the higher frequency due to less interference.
Configuring DNS to speed up response times
Users often confuse file download speed with server response time. If pages take a long time to load despite fast download speeds, the problem may lie with the provider's DNS servers. Standard servers may process requests slowly or have cache errors.
Changing DNS to public and fast servers from Google or Cloudflare can do wonders for browser responsiveness. On smartphones Xiaomi This can be done in two ways: through the settings of a specific Wi-Fi connection or through the global "Private DNS".
For quick setup, go to Settings → Wi-Fi, click the arrow next to your network and find "DNS Settings." Select "Manual" and enter the addresses: 8.8.8.8 And 8.8.4.4 (Google) or 1.1.1.1 (Cloudflare).
⚠️ Attention: The settings menu interface may differ depending on your MIUI or HyperOS version. Look for sections related to IP settings or DNS.
A more advanced method is to use the "Private DNS" feature, which encrypts requests. You can enable it by following this path: Settings → Connection and Sharing → Private DNS. In the hostname field write dns.google or 1dot1dot1dot1.cloudflare-dns.comThis will not only speed up but also protect your requests from your provider.
| DNS provider | Address 1 (Main) | Address 2 (Alternative) | Peculiarities |
|---|---|---|---|
| Google Public DNS | 8.8.8.8 | 8.8.4.4 | High stability, global coverage |
| Cloudflare | 1.1.1.1 | 1.0.0.1 | Focus on privacy and response speed |
| Quad9 | 9.9.9.9 | 149.112.112.112 | Blocking malicious domains |
| OpenDNS | 208.67.222.222 | 208.67.220.220 | Flexible filtering settings |
Hidden Android settings and the engineering menu
operating system Android, on the basis of which it operates MIUI, contains hidden settings for developers that allow fine-tuning the Wi-Fi module's behavior. However, caution is advised: incorrect changes may result in unstable connection.
To access the developer menu, go to Settings → About phone Tap the MIUI version seven times quickly. Then, in the "Advanced" → "Developer options" section, find the "Network" section. Here you'll find options that affect how aggressively the phone switches between networks.
One useful feature is disabling network scanning in sleep mode. Find the "Always scan for networks" option or something similar and disable it. This will prevent constant micro-interruptions while the phone tries to find the best network in the background.
There is also a myth about the code ##4636##, which opens the test menu. In modern versions Xiaomi This code is often blocked or prevents direct access to the Wi-Fi radio module, primarily operating for cellular communications. Don't waste time searching for the "magic button" where there isn't one.
Optimizing router performance
A smartphone is only half the equation. The other half is the access point. If your router is old or improperly configured, no matter what Xiaomi won't be able to get the most out of it. Make sure your equipment supports the standard. Wi-Fi 5 (ac) or Wi-Fi 6 (ax).
Channel width is a critical parameter. For the 2.4 GHz band, 20 MHz is optimal, as 40 MHz in this range creates significant interference. For 5 GHz, feel free to use 80 MHz or even 160 MHz, depending on the router and the distance to the client.
Channel selection also plays a role. Use analysis apps (such as Wi-Fi Analyzer) to find the least crowded channel. In the 2.4 GHz band, this is usually channels 1, 6, or 11. In the 5 GHz band, it's best to leave channel selection on "Auto" if your router is smart enough.
⚠️ Attention: Router manufacturers regularly update their firmware, changing the interface and layout of settings. If you can't find a specific setting, consult the documentation for your specific model.
Don't forget about physical placement. The router should be as high as possible and in the center of the apartment. Metal structures, mirrors, and aquariums significantly block the signal. Place the antennas vertically for better horizontal coverage.
Additional influencing factors
There are a number of less obvious factors that can choke your Wi-Fi. For example, Bluetooth can create interference if it's used to transfer large amounts of data while actively downloading files.
It's also worth checking if you have any "cleaners" or antivirus programs with VPN functionality installed on your phone. These can route all traffic through their servers, which inevitably reduces speed. Disable them to check.
Background app refreshes in Google Play or GetApps They can also consume all available bandwidth. Go to your app store settings and disable auto-updates over mobile networks or limit background activity.
- 🔋 Energy saving: Aggressive modes can disable the Wi-Fi module to save battery power.
- 📶 Case: Metallic or thick cases can shield your smartphone's antennas.
- 🔄 Cache overflow: A full system cache can slow down the processing of network requests.
If all else fails, there may be a hardware issue with the smartphone's antenna module, especially if the device has been dropped or exposed to moisture. In this case, software solutions will be ineffective.
The influence of cases on the signal
Some protective cases, especially those with metal inserts or magnetic rings for car mounts, can significantly reduce signal reception. Try removing the case and running a speed test—the difference can be surprising.
Frequently Asked Questions (FAQ)
Why is Xiaomi's Wi-Fi speed slower than iPhone's?
This is a common misconception. Modern flagships Xiaomi have modules no worse than Apple's. The difference may be in the signal processing algorithms, firmware version, or simply that the iPhone is better optimized for specific networks. Check the channel width and frequency settings.
Does the Wi-Fi Booster app help?
In 99% of cases, such apps are just marketing hype. They can reset the DNS cache or show signal strength, but it's impossible to physically boost antenna reception programmatically. It's better to use the system's built-in tools.
Is it worth buying a Wi-Fi 6 router for an old Xiaomi?
If your smartphone doesn't support the 802.11ax (Wi-Fi 6) standard, purchasing such a router will only provide a performance boost due to a more powerful processor and better antennas, not the new communication standard. Check your phone's specifications.
How can I check which Wi-Fi standard is currently being used?
It's hard to see this in the standard Android interface. Use third-party utilities like WiFi Analyzer or Network Analyzer, which will show the current link speed (Link Speed) and standard (n, ac, ax).
Can a virus slow down Wi-Fi?
Yes, malware can use your connection for mining or spamming, hogging your bandwidth. Run a full scan of your device with a built-in security scanner or an antivirus from a reputable vendor.
