Situations where you urgently need to access the global network for a laptop or tablet, but you don't have a desktop router at hand, arise quite often. Modern Huawei smartphones, whether models from the P, Mate or budget lines Nova, do an excellent job of acting as a mobile router, providing a stable connection via 4G and 5G technologies. Proper device configuration allows you to turn your gadget into a fully-fledged hot spot, to which up to ten or more gadgets can be connected simultaneously without significant loss of speed.
However, the manufacturer's default settings are far from optimal for all usage scenarios. Users often experience rapid battery drain, overheating, or the inability to find a network on older devices due to frequency band incompatibility. Understanding the intricacies of wireless modules in EMUI or HarmonyOS will allow you to not only enable this feature but also make it as efficient and secure as possible.
In this article, we'll take a detailed look at the entire process of setting up a wireless network, focusing on security and energy-saving options. You'll learn how to hide your access point from prying eyes, which frequency band to choose for maximum speed and which for best compatibility, and why it's sometimes worth changing the default network name.
Activating tethering mode through quick settings
The fastest way to enable tethering on Huawei devices is to use the quick action bar, which is hidden at the top of the screen. To do this, swipe down from the top of the screen to reveal the notification shade and look for the icon labeled "Tethering" or "Tethering & Hotspot." If you don't see the desired option when it's collapsed, tap the edit button (usually a pencil or three dots) to expand the full list of available options.
After clicking the corresponding icon, the system instantly activates the Wi-Fi module in broadcast mode. At this point, a characteristic icon resembling a two-link chain or a wireless signal symbol with numbers will appear in the status bar. This means that mobile hotspot is already running and ready to accept connections using the current network name and password settings that were previously set or were installed by the factory.
However, this method is only good for emergency activation. It doesn't allow you to change security settings or frequency range on the fly. Initial setup or changing important parameters will still require accessing the system's deep menu, where more advanced network traffic management tools are hidden.
Please note that when activating via the notification shade, your phone may not notify you that devices have already connected to the network. It is recommended that you still check the settings after activating via the quick switch to check the list of clients.
Deep access point settings in the smartphone menu
To gain full control over the network settings, you need to go to the system settings. The path to this section may vary slightly depending on the EMUI or HarmonyOS version, but the general logic remains the same. Open the "Wireless Networks" section or go directly to "Mobile Hotspot," where all the key configuration settings are located.
Inside the "Wi-Fi hotspot settings" menu, you'll see a panel with the main settings. Here you can change SSID (network name), make it visible or hidden, and set a strong password to protect against unauthorized access. Pay special attention to the "Password" field: use a combination of letters and numbers at least 8 characters long to prevent neighbors from guessing the key in public places.
One of the most important features is frequency band management. In the "AP Band" or "Configure Access Point" menu, you can choose between 2.4 GHz and 5 GHz. The first option provides better range and compatibility with older devices, but has lower speeds. The second option, 5 GHz, gives the maximum data transfer speed, but the signal range will be significantly smaller, and many older laptops may simply not see your network.
Also available in this section is often the "Traffic Limit" or "Data Limit" feature. This is an extremely useful tool that allows you to set a strict limit on the amount of data transferred. Once the limit is reached, the phone will automatically disable tethering, saving you from unexpected charges when using plans with limited gigabytes.
☑️ Check security settings
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
Choosing the right frequency is critical to ensuring a stable connection. The 2.4 GHz band is the most common. Almost all wireless devices released in the last 15 years, from older printers to budget smartphones, operate in this range. Signals at this frequency better bypass obstacles such as walls and furniture, allowing you to broadcast internet even if your phone is in another room.
However, the 2.4 GHz frequency has a serious drawback: airwave congestion. In apartment buildings, dozens of neighbors' routers, microwave ovens, and Bluetooth headsets operate in this frequency range. This creates a high level of interference, resulting in a drop in actual speed and increased ping, which is especially noticeable during online gaming or video calls.
The 5 GHz band offers much cleaner air and wider data transmission channels. If you need to transfer a large file or watch 4K video on a tablet connected to your phone, this is the ideal option. Speeds in this mode can reach hundreds of megabits per second, depending on cellular network coverage. However, keep in mind that the 5 GHz signal has very poor penetration through walls and quickly fades over distance.
Why don't older laptops see the 5 GHz network?
Many network cards released before 2013-2015 do not physically support the 802.11ac or 802.11ax standards, which operate in the 5 GHz band. For such devices, the only option is to switch the Huawei access point to 2.4 GHz mode.
When choosing a mode, consider the task at hand. For working with documents and email in a cafe, 2.4 GHz is perfectly sufficient. For streaming or gaming in close proximity to your phone, it's better to switch to 5 GHz.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Compatibility | Almost 100% of devices | Only modern gadgets |
| Penetration ability | High (through walls) | Low (line of sight only) |
| Maximum speed | Up to 150 Mbps | Up to 800+ Mbps |
| Interference level | Tall (many neighbors) | Low (pure ether) |
Connection security and network hiding
Security concerns when using the public internet come to the forefront. Huawei's default encryption standard is WPA2 PSK, is reliable and time-tested. It protects transmitted data from simple eavesdropping. However, if an attacker connects to your access point, they could theoretically attempt to intercept unencrypted traffic within your local network. Therefore, never conduct banking transactions on clients' devices unless you are sure of their owners.
One of the most effective security measures is the "Hide Device" or "Hide SSID" feature. When enabled, your phone stops broadcasting its network name. Your Huawei will simply not appear in the list of available Wi-Fi networks around you. To connect, you will have to manually enter the exact network name (SSID) and password in your device's Wi-Fi settings.
This creates an additional barrier for casual users and "Wi-Fi hunters" scanning the airwaves for vulnerable spots. However, it's worth remembering that for an experienced hacker with professional equipment, hiding the SSID isn't an insurmountable obstacle—such networks are still visible in scanner logs, they're simply marked as "hidden." Nevertheless, for everyday security, this is quite sufficient.
⚠️ Important: When enabling SSID hiding, be sure to write down the exact name of your network. If you forget its name, you'll have to reset the access point or connect your phone to your computer via USB to see the current name in the system.
You can also configure a "Whitelist" of devices in the security menu. In this mode, only devices whose MAC addresses you've previously added to the allowed list will be able to connect to your access point. All other devices, even with the password, will be denied connection.
Energy saving and control of connected devices
Sharing Wi-Fi is one of the most power-hungry processes on a smartphone. The network module operates at maximum power, the processor processes network packets, and the screen, if turned on, consumes the lion's share of the power. As a result, the battery can drain after 2-3 hours of active use. To minimize this loss, Huawei has a "Wi-Fi timeout" option in its hotspot settings.
This feature automatically disables tethering if no devices are connected to the network for a certain period of time (e.g., 10 minutes). This prevents you from forgetting to turn off tethering and letting your phone run out of battery in your bag.
In the "Connected Devices" menu, you can always see a list of devices currently using your internet connection. The device name and the amount of data transferred are displayed here. If you see an unfamiliar user, you can block them directly from this menu by clicking the corresponding button. Blocking occurs instantly, and the offender's internet access is lost.
Some users also recommend disabling background syncing of photos and heavy apps on the share phone itself, so that the entire bandwidth is allocated to client devices rather than being used for internal system needs.
Alternative distribution methods: USB and Bluetooth
If wireless sharing is unavailable or unstable, Huawei offers alternative internet transfer options. A USB modem is an excellent choice for connecting a laptop or desktop PC. This method not only transfers data but also charges the smartphone, which is critical for extended use. Cable connection speeds are generally more stable and higher than wireless.
To activate USB modem, connect your phone to your computer using a cable, go to the hotspot settings, and toggle the "USB modem" switch. The computer will recognize the device as a new network connection. Drivers are usually installed automatically, but in rare cases, you may need to install the Huawei HiSuite app or standard drivers from the manufacturer's website.
Bluetooth modem is an emergency option when you need to transfer a quick text or email but your Wi-Fi module is damaged or busy. The speed is very low (no more than 1-2 Mbps), but the power consumption is minimal. To set it up, pair your devices via Bluetooth, then enable "Bluetooth modem" in the access point menu.
⚠️ Important: When using a USB modem, make sure the cable is working properly and supports data transfer. Cheap "charge-only" cables will not activate the modem mode, and your computer will not see the network.
The choice of method depends on your priorities: speed and convenience (Wi-Fi), stability and charging (USB), or energy saving (Bluetooth).
Common problems and their solutions
Sometimes users encounter a situation where their phone is broadcasting Wi-Fi, but the internet on connected devices isn't working. This is most often due to mobile network settings. Check that data is enabled in general. Also, make sure you have 4G/LTE coverage. If the phone switches to 2G/Edge due to a poor signal, the speed will be so low that pages simply won't load.
Another common issue is an IP address conflict or a DHCP table overflow. If multiple devices were connected to the access point, a simple modem reset (turning it off and on again) can sometimes help. It's also worth checking if there's a connection limit. Some firmware versions have a default limit of 4 devices, which can be increased to 8 or 10 in the settings.
If devices are connecting and disconnecting, check your power saving settings. Huawei's aggressive algorithms may be killing the tethering process to save battery. Add the Mobile Hotspot app or system process to the power saving mode exceptions.
In rare cases, the problem may be with your carrier, blocking traffic tethering. This can be verified by connecting your phone to a PC via USB: if you can connect via cable but not via Wi-Fi, your carrier may be using TTL filtering. Solving this issue requires more complex manipulations involving changing the TTL at the system level.
Why does my phone heat up quickly when using Wi-Fi?
Heating is caused by the simultaneous operation of the cellular modem (receiving 4G/5G) and the Wi-Fi transmitter (distributing). This is normal. To reduce the temperature, remove the case, place the phone on a hard surface (such as a table), and do not cover it with a cloth. Heating may be more intense in hot weather.
Is it possible to share Wi-Fi if the phone has a SIM card password?
Yes, you can. The PIN is only requested once when the phone is turned on. Once the network is found and the SIM card is unlocked, tethering works without any additional restrictions related to SIM card security.
How many devices can work simultaneously via Huawei hotspot?
Modern Huawei models typically support 8 to 10 simultaneous connections. However, the actual number depends on the processor load and RAM. When connecting 10 devices, the speed on each device will be split, and performance may decrease.
