The modern smartphone has long ceased to be just a device for making calls, turning into a full-fledged mobile office and entertainment center. Model Huawei P20 Lite, despite its age, is still popular due to its balanced performance and high-quality camera, but for many users, the question of using it as a router remains relevant. distribute Wi-Fi Whether you're traveling, at the dacha, or in a situation where your home internet provider is temporarily unavailable, this feature is one of the most in-demand tools for Android device owners.
The process of activating the modem mode on the EMUI shell, which is installed on P20 Lite, has its own unique features that distinguish it from standard Android. Users must not only enable the feature but also properly configure security settings to prevent unauthorized access to personal data. In this guide, we'll cover all the nuances of creating a wireless network, from basic activation to advanced frequency range settings.
Before tweaking settings, make sure your device has mobile data enabled or a stable Wi-Fi connection for the connection you plan to share. It's important to understand that tethering drains battery power significantly faster than regular use, so having a charged battery or connecting to an external power source is a smart move before getting started.
Basic hotspot activation via settings
The initial setup of the modem mode is carried out through the main system settings menu. You need to open the section Settings, which is usually represented by a gear on the desktop or in the notification shade. Next, find the item Wireless networks or go directly to the subsection Mobile network, where the main tools for managing your Internet connection are hidden.
Inside the mobile network menu we are interested in the option Wi-Fi hotspotClicking this item takes you to the signal broadcast control menu. Here, first, activate the switch at the top of the screen by moving it to the "On" position. The system will automatically generate a network name (SSID) and password, which will be used by default for connecting other devices.
However, relying on default settings isn't always wise, especially if you plan to use the hotspot regularly. It's recommended to immediately change the network name to something unique so you can easily recognize it in the list of available connections, and set a strong password. This will protect your traffic from unauthorized users who might try to connect to your network. Huawei P20 Lite without your knowledge.
☑️ Preparing to launch the access point
Setting up security and network settings
Deep security configuration is a critical part of the process, as sensitive data may be transmitted through your network. In the access point menu on Huawei P20 Lite you should select the item Setting up a Wi-Fi hotspotHere you can change not only the name and password, but also the encryption type.
The system offers several protection options, but the optimal choice is the standard WPA2 PSKThis protocol ensures reliable encryption of data transmitted between your smartphone and connected devices. Using outdated protocols or an open network (without a password) makes your traffic vulnerable to interception, so we strongly recommend not ignoring this setting.
You can also configure SSID hiding in this section, making your network invisible to general scanning. Connecting to it will only be possible by manually entering the network name on the client device. This adds an additional layer of privacy, although it does make the connection process a bit more complicated for guests.
⚠️ Important: If you decide to hide the network name (SSID), make sure you remember its exact spelling, taking into account the case of letters, as the only way to restore a forgotten name is by resetting the access point settings on the smartphone itself.
For easy connection management, a list of connected devices is available in the settings. Here you can see exactly who is using your internet and, if necessary, block unwanted users with a single tap. Blacklist Allows you to permanently block access to specific MAC addresses.
Using the 5 GHz frequency band
One of the advanced features available on Huawei P20 Lite, is the ability to select the frequency band for Wi-Fi distribution. By default, the smartphone uses the 2.4 GHz band, which has a longer range but is slower and susceptible to interference from neighboring networks and household appliances.
Switching to a range 5 GHz This significantly increases data transfer speeds and reduces interference. This is especially important if you plan to stream high-definition video or play online games on a connected device. However, it's important to keep in mind that the 5 GHz signal has a shorter range and penetrates walls less effectively.
To change this setting, find the item in the access point settings menu AP range or Frequency range. Select a value 5.0 GHz from the provided list. After saving the settings, the network will restart on the new frequency, and all devices will need to be reconnected.
The influence of frequency on autonomy
Using the 5 GHz band may consume slightly more power from the Wi-Fi module, but due to faster data transfer, the total time of active operation in modem mode may even increase, since the radio interface spends less time in the active state of transmitting packets.
Not all older devices support the 5 GHz band. If you need to connect older devices to your access point, it's best to stick with the standard 2.4 GHz band for maximum compatibility.
Managing traffic and connection limits
Monitoring mobile data usage is a crucial feature for those who don't have an unlimited data plan. Huawei P20 Lite A convenient system for limiting the amount of data transferred has been implemented. In the access point menu, select Traffic limitation or Traffic limit.
Here you can set the maximum amount of data that can be used by connected devices. Once the limit is reached, Wi-Fi sharing will automatically stop, saving you from unexpected charges. You can set the limit in megabytes or gigabytes and select the period for which the limit applies (e.g., daily or monthly).
In addition to traffic, it's important to control the number of simultaneous connections. You can set a limit on the number of users in the settings, typically from 1 to 8 devices. Setting a reasonable limit, such as 3-4 devices, will help maintain stable internet speeds for primary users and reduce the load on the smartphone's processor.
| Parameter | Recommended value | Impact on the system |
|---|---|---|
| Max connections | 3-4 devices | Maintains high speed and reduces heat |
| Frequency range | 5 GHz (for speed) | Less interference, higher speed, smaller radius |
| Time-out | 5-10 minutes | Saves battery when there are no clients |
| Encryption | WPA2 PSK | Maximum protection of transmitted data |
The hotspot timeout feature is also useful. If no one is connected to the network or there is no activity for a set period of time (e.g., 10 minutes), the smartphone will automatically disable tethering. This helps significantly. save battery power, if you forgot to turn off the function manually.
Alternative ways to distribute Internet
In addition to the classic Wi-Fi hotspot, Huawei P20 Lite offers other ways to share an internet connection, which may be more effective in certain situations. One such method is sharing via a USB cable.
To activate this mode, connect your smartphone to your computer using a high-quality data cable. Then, in the settings menu, under Wireless networks -> Modem mode, activate the switch USB modemThe computer will detect the new network connection, and the Internet will become available immediately.
- 🔌 Stability: Wired connection provides maximum stability and speed, eliminating radio interference.
- 🔋 Charger: While data is being transferred, the smartphone's battery is being charged, which is critical during long-term operation.
- 🛡️ Safety: Data is transmitted via cable, which eliminates the possibility of intercepting the signal over the air.
Another option is sharing via Bluetooth. This method is less popular due to its low data transfer speed, but it can be a lifesaver in emergency situations when you need to transfer a small amount of text information or check email and have no other options. Bluetooth modem speeds are significantly slower than Wi-Fi, so it's not suitable for watching video.
Solution and optimization of work
During operation, users may encounter various difficulties, such as slow speeds, constant connection drops, or an inability to connect to the network. Often, the problem stems from device overheating or operating system software glitches. EMUI.
If your connection speed is unsatisfactory, try restarting your smartphone. This will clear the temporary network service cache and restart the radio interface. It's also worth checking your mobile network signal strength: if you only have one signal, high Wi-Fi speeds are physically impossible, regardless of your phone's settings.
⚠️ Caution: When operating in hotspot mode for extended periods, the smartphone's body may become very hot. This is a normal physical reaction, but if the temperature reaches a critical level, the system may forcibly disable the Wi-Fi module to protect its components.
To optimize performance, it's recommended to run background apps on your smartphone while it's using the modem. Heavy processes can compete for processor and radio resources, causing lag on connected devices. Also, make sure your phone isn't running automatic app updates or downloading large files.
In some cases, resetting network settings helps. Go to Settings -> System -> Reset -> Reset network settingsPlease note that this action will delete saved Wi-Fi passwords and Bluetooth settings, but it often resolves connection issues.
The impact of tethering on battery life
Hotspot mode is one of the most power-hungry processes in a smartphone. The radio module simultaneously receives a signal from the base station and transmits data via Wi-Fi, creating a double workload. Huawei P20 Lite With its 3000mAh battery capacity, the battery can drain very quickly.
To minimize power consumption, it's recommended to reduce screen brightness or turn off the display completely while sharing. The screen is one of the largest energy consumers, and leaving it running while your phone is in your pocket as a router is pointless. You can also enable power saving mode to limit background activity.
If you plan to use your smartphone as a stationary router for an extended period, it's best to keep it plugged in. However, keep an eye on the case temperature, as simultaneously charging and active communication modules can generate significant heat, which can be detrimental to the lithium-polymer battery in the long term.
Why does the hotspot on my Huawei P20 Lite turn off by itself?
Automatic shutdowns are most often caused by a timeout setting. Check the "Turn off hotspot" setting in the hotspot menu to see if the inactivity timeout is set. This could also be caused by the device overheating or reaching its data limit.
Is it possible to share Wi-Fi if the phone is connected to a Wi-Fi network?
On most Android versions and EMUI, this feature is called "Wi-Fi Relay" or "Wi-Fi Bridge." If your software version supports this feature, you can receive and share internet over Wi-Fi. If this option isn't available, your phone will use mobile data (4G/3G) to share, even if Wi-Fi is enabled.
How do I change my password if I forgot it?
If you've forgotten the password for the hotspot you created, you can't view it in plain text on connected devices without root access. The easiest way is to go to the hotspot settings on the Huawei P20 Lite itself, where the password is displayed in the input field (you can tap the eye icon), and change it.
How many devices can be connected to the P20 Lite at the same time?
Technically Huawei P20 Lite Supports up to 8 simultaneous connections. However, to ensure stable speed and avoid processor overheating, it is recommended to limit the number of active devices to 4-5, especially if they consume a lot of traffic.
