Modern smartphones have long ceased to be just devices for making calls, turning into powerful tools for work and entertainment, capable of replacing a mobile router in any situation. Model Huawei P40 lite E is no exception, offering users flexible options for creating a personal wireless internet zone. This is especially useful when traveling, on business trips, or temporarily without a wired internet connection, and needing to quickly connect a laptop or tablet to the network.
The process of activating the modem mode in the Android operating system, on which it runs EMUI, is quite simple and doesn't require extensive technical knowledge. However, to ensure a stable connection and maximum data security, it's important to properly configure network settings, select the optimal frequency, and set a strong password. In this guide, we'll cover all the steps necessary to turn your smartphone into a fully-fledged internet source.
Preparing your smartphone for modem mode
Before setting up the hotspot, you need to make sure your device is ready to transmit data. The first and most important requirement is an active SIM card with a mobile data plan. Without a valid 3G or 4G connection, internet tethering will be impossible, as the phone will have nothing to broadcast to other devices.
It's also worth checking the battery level, as access point mode is a power-hungry process. Operating the radio module in constant signal transmission mode significantly increases power consumption, which can lead to rapid battery drain. It's recommended to keep your smartphone connected to a charger or have a power bank handy if you plan to use it as a router for extended periods.
- π± Make sure you have inserted a SIM card with an active tariff plan.
- π Check the battery charge level (preferably more than 30%).
- π‘ Make sure you have a strong cellular network signal.
- βοΈ Update your network settings to the latest ones through your operator's menu.
An important preparation step is checking your mobile network settings. Sometimes, carriers require manual entry of parameters. APN for the internet to function correctly, although in most cases they are installed automatically when the SIM card is first inserted. If mobile internet isn't working on the smartphone itself, then tethering won't work either, so troubleshooting connection issues should be done before activating tethering mode.
Activating Wi-Fi Hotspot on Huawei P40 Lite E
The process of enabling Internet sharing in the shell EMUI The setup is intuitive and takes just a few seconds. First, unlock your smartphone's screen and find the "Settings" icon on the home screen or in the app drawer. This is the central control hub for all device functions, and it contains the switches we need.
In the settings menu, find the section usually labeled "Wireless & Networks" or "Mobile Networks." The interface may vary slightly depending on the firmware version, but the logic remains the same. Within this section, look for "Tethering" or "Wi-Fi Hotspot." This is where all the tools for managing your internet connection are located.
β οΈ Attention: When you turn on the hotspot, your smartphone may automatically disconnect an already active Wi-Fi connection if it was used to access the Internet, as the antenna switches to receive a cellular network signal for further retransmission.
Once you've navigated to the desired section, simply slide the switch to the "On" position. The system may ask you to confirm the action or warn you that other devices will be able to see your phone in the list of available networks. Once enabled, a corresponding icon will appear in the top status bar, indicating that your device is ready to connect to clients.
For quicker access to this feature, you can use the notification panel. Swiping down from the top of the screen will open the quick settings panel, where the "Tethering" tile is often located. If it's not on the main screen, swipe left or tap the edit button to add this shortcut for future reference.
Setting up a network name and security password
By default, the system suggests using a standard network name, which often contains the device model and a set of random characters. This is not only inconvenient for searching among numerous other networks, but also unsafe, as it reveals information about your phone model. It is recommended to change it. SSID (network identifier) ββto a more understandable and unique name that is easy to recognize in the list of available connections.
Particular attention should be paid to setting the password. Security protocol WPA2 PSKThe default password is quite secure, but only if you use a complex passphrase. Avoid using simple combinations like "12345678" or your date of birth, as these are easily guessed by malicious users who want to access your traffic or data.
To change the settings, click "Access Point Name" or "Password" in the access point menu. In the window that opens, enter the desired name and create a secure combination of upper- and lower-case letters and numbers. The minimum password length is typically 8 characters, but for greater security, it's best to use longer keys.
An example of a strong password: Hw_P40_Lite#2026!After making changes, be sure to click "Save" or "OK" for the new settings to take effect. If other devices were already connected to your network, they may require you to re-enter your password, as the saved data will no longer comply with the updated security settings.
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
One of the important settings available in modern Huawei smartphones is selecting the frequency band for the access point. By default, the device operates in the 2.4 GHz band, which has a longer range and better penetration through walls. However, this band is often overloaded with signals from nearby routers and household appliances, which can reduce connection speed.
The 5 GHz band offers significantly higher data transfer rates and is less susceptible to interference, but it has a shorter range. If you plan to connect devices that require high speeds (such as 4K video or video conferencing) and are in close proximity to your smartphone, it makes sense to switch to this frequency.
To change the band, find "AP Band" in the access point settings menu. Select the desired value: 2.4 GHz for compatibility with older devices and a longer range, or 5 GHz for maximum performance. Some older laptops or tablets may simply not see the 5 GHz network, so consider the specifications of the devices you're connecting to.
| Characteristic | 2.4 GHz | 5 GHz |
|---|---|---|
| Range of action | High | Average |
| Permeability of walls | Good | Low |
| Maximum speed | Up to 150-300 Mbps | Up to 400+ Mbps |
| Interference level | High | Short |
Managing connected devices and limits
Functional Huawei P40 lite E Allows you to not only share your internet but also control who is connected to your network. The hotspot menu includes a "Connected Devices" section, which displays a list of all devices currently using your data. This is a useful tool for identifying uninvited guests who might have guessed your password.
If you detect an unknown device, you can block it directly from this menu, preventing further network access. The system also allows you to set a limit on the number of connected devices, which helps prevent overloading the connection and the smartphone itself. It's generally recommended to limit the number of clients to 3-5 devices to ensure stable operation.
β οΈ Attention: Mobile operator interfaces and data plans may vary. Before actively tethering, make sure your plan allows you to use your smartphone as a modem, as some carriers may limit speeds or charge additional fees for tethering.
You can also set a traffic limit. You can set the maximum amount of data that can be used via the hotspot. Once the limit is reached, internet tethering will automatically stop, protecting you from unexpected charges if you're using a limited-gigabyte plan.

Troubleshooting Internet sharing
Despite the ease of setup, users may encounter situations where the hotspot doesn't work or connected devices can't access the internet. Common causes include service expiration or a lack of SIM card balance. First, always check your account balance and the availability of data plan data.
Another issue could be incompatibility of security protocols. If your old device can't connect to the network, try changing the encryption type in the access point settings from WPA2 to WPA or even Open (passwordless) to test, although the latter option is highly discouraged. Restarting your smartphone, which clears temporary network module errors, also helps.
Sometimes devices connect to Wi-Fi, but the internet is unavailable ("No internet access"). This often indicates issues with your mobile operator's APN settings. Go to your mobile network settings, select your SIM card, and check the "Access Point Names (APN)" options. Try resetting them to default settings or creating a new APN with the settings appropriate for your operator.
If all else fails, reset your network settings. This will return all network settings, including Bluetooth and Wi-Fi, to factory defaults, but will not delete your personal data, photos, or contacts. After the reset, you'll need to re-enter passwords for known Wi-Fi networks and set up your hotspot.
Optimization and additional features
To extend battery life when using your smartphone as a router, you can use the "Portable Hotspot Schedule" feature. In the settings, you can set the time when internet sharing will automatically turn on and off. This is especially convenient if you only use your phone to share internet on your computer during work hours.
It's also worth mentioning the option of sharing the internet via a USB cable. This method provides a more stable connection and simultaneously charges the smartphone, eliminating the problem of rapid battery drain. To do this, connect the phone to the computer with a cable and select "USB Modem" in the modem menu. The computer will recognize the device as a network card.
Keep in mind that your smartphone may heat up when actively using Wi-Fi. This is a normal physical process associated with the processor and radio modules operating under load. However, if the device becomes excessively hot, we recommend removing the protective case to improve heat dissipation or reducing screen brightness to reduce the overall thermal load.
Is it possible to share Wi-Fi if your phone doesn't have a SIM card?
No, you need an active SIM card with a data plan to use mobile data. However, if the phone is connected to an external Wi-Fi network, some models can rebroadcast this signal, but the Huawei P40 lite E in its standard configuration uses the mobile network to create a hotspot.
How many devices can Huawei P40 lite E connect to at the same time?
Technically, the smartphone supports connections to up to 8-10 devices simultaneously. However, to ensure comfortable speeds, it's recommended to limit the number of clients to 3-5, as more connections can lead to a significant drop in speed and overheating.
Does Wi-Fi sharing affect the speed of mobile internet on the phone itself?
Yes, it does. The connection bandwidth is shared between the phone itself and connected devices. If you download a large file on a connected laptop, the page loading speed in the smartphone browser may decrease due to bandwidth sharing.
