Modern smartphones have long ceased to be just devices for making calls, turning into full-fledged mobile offices and multimedia centers. Model Redmi 7 ProDespite its age, the Wi-Fi hotspot remains a reliable tool capable of performing multiple functions, including serving as a router. Knowing how to properly configure a Wi-Fi hotspot on this device allows you to provide internet access to a laptop, tablet, or other phone anywhere there's mobile coverage.
In this article, we'll cover in detail the process of activating tethering mode, choosing optimal security settings, and signal frequency. You'll learn how to extend your device's battery life in tethering mode and what to do if connected devices can't see the network. Proper setup will allow you to use your smartphone as efficiently as possible, turning it into a full-fledged source of high-speed Internet.
Before we get into the technical part, it's worth noting that the shell interface MIUI may vary slightly depending on the firmware version. However, the basic operating principles of the Wi-Fi module remain the same across the entire ecosystem. XiaomiWe'll look at the standard workflow that applies to most users.
Preparing the device to operate in router mode
The first step before activating the hotspot is to check the status of your SIM card and data plan. Make sure the correct one is installed on your device. APN (access point) provided by your mobile operator. Without the correct network settings, the internet will not work on connected devices, even if the 4G indicator is lit.
⚠️ Please note: Check your remaining data plan before enabling data sharing. High-definition videos or downloading large files on a laptop can quickly exhaust your data plan's limits.
It's also critical to assess the battery level. Access point mode significantly increases power consumption, as the radio operates at increased power to ensure stable coverage. If your smartphone's battery is below 20%, it's recommended to connect the device to a power source or power bank.
Don't forget to check if you're currently in power saving mode, which can block background processes or limit Wi-Fi to conserve battery life. In some versions, MIUI Aggressive power saving mode may interrupt connection when screen is off.
☑️ Pre-launch check
Step-by-step Wi-Fi hotspot activation
The process of enabling Internet distribution on Redmi 7 Pro It takes no more than a minute if you know where the necessary switches are. There are two main ways to start this process: through the notification shade or through the main system settings menu.
The fastest method is to swipe down from the top of the screen. In the Quick Settings panel, look for the icon labeled "Tethering" or "Wi-Fi." If the icon isn't on the first page, swipe left to reveal additional widgets. Tapping this button instantly activates tethering mode with the most recently used settings.
More in-depth customization is available through the system menu. To do this, go to the section Settings, then select the item Additional functions (In some versions, it may be called "Connections and Sharing"). This is where all the necessary network management controls are located.
- 📱 Open the Settings app from your home screen.
- 🔗 Go to the "Advanced Features" or "Connections and Sharing" section.
- 📡 Select "Wi-Fi hotspot".
- 🟢 Move the switch to the active position.
Once enabled, you'll see a notification in the status bar indicating the number of connected devices. Typically, one client or "No connections" is displayed by default. By clicking the network name in the same menu, you can see a list of devices currently using your data.
Setting up a network name and security settings
Access points are often factory-set with a default network name (SSID), which may be the same for many users within range. To avoid confusion and potential connection conflicts, as well as for your own security, you should change the network name to a unique one.
In the access point settings menu, click the "Access point name (SSID)" field. Enter an easily recognizable name, such as "My_Redmi_Net" or anything else you can quickly find in the list of available networks on your laptop. Avoid using special characters, as some older devices may not display them correctly.
The most important security setting is the choice of encryption protocol. For the Redmi 7 Pro, WPA2 PSK is recommended, as it provides reliable data protection from interception.The password should be complex enough to prevent neighbors or passersby from connecting to your network without permission. Use a combination of letters and numbers, at least 8 characters long. Remember or write down the password, as you'll need to re-enter it each time you connect your device if the save function fails.
Selecting a frequency range and Wi-Fi standard
One of the key features of setting up an access point on modern Android smartphones is the ability to select a frequency range. Redmi 7 Pro supports operation in different ranges, which allows the network to be adapted to the capabilities of connected clients.
In the access point settings, find the "AP Band" option. Here, you'll be asked to choose between 2.4 GHz and 5 GHz (if supported by the module in this mode) or let the system choose. The 2.4 GHz standard has a longer range and penetrates walls better, but it's slower and susceptible to interference from microwave ovens and neighboring routers.
The 5 GHz band offers significantly higher data transfer rates and is less congested, but its signal range is shorter. If you plan to watch 4K video or play online games on your phone, 5 GHz is preferable, provided the receiving device supports it.
| Parameter | 2.4 GHz | 5 GHz |
|---|---|---|
| Speed | Up to 150-300 Mbps | Up to 400+ Mbps |
| Range | Big | Medium/Small |
| Penetration | High | Low |
| Compatibility | All devices | New devices only |
If you're unsure which band to select, leave the "Auto" or "Default" setting. The system will automatically determine the optimal operating mode based on the connected equipment and the level of external interference.
Why can't my laptop see the 5 GHz network?
Many older laptops and tablets are equipped with Wi-Fi adapters that only operate in the 2.4 GHz band. If you've enabled only 5 GHz on your phone, your older device simply won't detect the network. Switch to 2.4 GHz for maximum compatibility.
Managing connected devices and limits
Functional Redmi 7 Pro It allows you to not only share the internet but also control who exactly is using it. The access point menu often includes a "Connected Devices" section, which displays the MAC addresses and names of devices connected to the network.
You can manually limit the number of connected devices. This is a useful feature if you want to prevent bandwidth congestion or protect yourself from freeloaders. Set a limit of, for example, 3-4 devices to ensure no one else can connect, even if they learn the password.
- 🚫 Click on the name of the connected device in the list.
- 🔒 Select the "Block" or "Disable" option.
- ✅ Change your password if you suspect it has been compromised.
It's also worth paying attention to the activity timer. Some firmware versions offer an option to automatically turn off the hotspot if no one connects to it for a certain period of time (for example, 5 or 10 minutes). This helps conserve battery life if you forget to turn off tethering mode.
Solution: If the Internet doesn't work
Despite the simplicity of setup, users may encounter a situation where Wi-Fi is available, but the connected device has no internet access. Most often, the problem lies with the smartphone's mobile network settings or carrier restrictions.
The first thing you need to do is check if the internet is working on the device itself. Redmi 7 ProOpen your browser and try loading any page. If the pages don't load, the problem isn't with the access point, but with the signal reception or the SIM card balance. Try turning airplane mode on and off to reboot the communication module.
⚠️ Note: Some mobile operators block or charge separately for tethering. If you see a connection but the pages don't open, your plan may not support this feature or require additional APN configuration.
Another common cause is an IP address conflict or DNS error. Try setting static DNS addresses on the receiving device (laptop), such as Google's (8.8.8.8 and 8.8.4.4). Resetting the network settings on the Xiaomi smartphone itself may also help, but this will delete all saved Wi-Fi passwords.
If the issue persists, check the date and time on both devices. An incorrect system date can cause security certificate errors, causing browsers to block access to websites, claiming the connection is not secure.
Optimizing power consumption and stability
Wi-Fi distribution is an energy-intensive process. Redmi 7 Pro The phone may become hot and drain quickly in this mode. To minimize heat buildup, avoid covering the phone with a cloth or placing it in direct sunlight while in router mode.
To extend battery life, you can reduce your smartphone's screen brightness to a minimum or turn off the display completely if your model allows background operation without blocking Wi-Fi. However, keep in mind that some versions MIUI can "kill" background processes to save energy.
It's recommended to add the "Access Point" process to the power saving exceptions list. To do this, go to the battery settings, find the running app, and select "Unrestricted" mode. This will prevent the hotspot from suddenly stopping when the screen goes dark.
Using an external power source is the best option for extended battery life. Connect your phone to a charger or power bank. This will not only offset power consumption but also prevent overheating, as some of the heat will be dissipated through the charger (if connected via a cable).
Is it possible to share Wi-Fi if the SIM card on the phone has a password?
Yes, you can. The PIN is only required when turning on the phone or rebooting. As long as the SIM card is unlocked and the network is active, the hotspot function works normally, regardless of the PIN on the SIM card itself.
What is the maximum number of devices that can be connected to Redmi 7 Pro?
Technically, the firmware allows for connecting up to 10 devices simultaneously. However, the actual number depends on the processor load and mobile internet speed. If more than 3-4 active devices are connected, the speed on each device may drop to an unacceptable level.
Does Wi-Fi sharing affect the speed of mobile internet on the phone itself?
Yes, it does. The bandwidth is shared between all connected clients. If a laptop starts downloading a large file, browsing speed on the smartphone itself will also decrease, as the bandwidth of the radio module and the operator's channel is limited.
What should I do if the access point turns off by itself after 5 minutes?
Most likely, you have the auto-off timer enabled. Check your access point settings and find the "Timer" or "Auto-off" option, setting it to "Never" or the maximum time. Also, check your power saving settings.
