- 🔒 Security: Select the WPA2 PSK encryption protocol for maximum security.
- 🔑 Password: Come up with a combination of letters and numbers that is at least 8 characters long.
☑️ Check security settings
After saving the settings, the network will be searchable. On the receiving device (laptop or tablet), find the created network in the list of available Wi-Fi connections, enter the set password, and enjoy the internet. The connection process usually takes no more than 10-15 seconds.
Advanced settings: frequency range and limits
Owners Huawei P20 Lite They offer the ability to fine-tune broadcasting parameters. One key factor is the choice of frequency band. The smartphone supports both 2.4 GHz and 5 GHz bands (subject to hardware and firmware support). The P20 Lite typically operates in 2.4 GHz for better compatibility, but checking the settings is essential.
The 2.4 GHz band offers a wider range and better penetration through walls, but it's often congested with neighbors' routers and appliances. If you're in an apartment building, your speed may drop. The 5 GHz band is less crowded and offers faster speeds, but has a shorter range.
To switch the range, go to Wi-Fi hotspot settings → AP rangeIf you are not sure which option to choose, leave the value 2.4 GHz - This ensures compatibility with older devices such as old laptops or game consoles.
Another important feature is limiting the number of connected devices. This helps control the load on the smartphone's processor and prevents unauthorized access. You can set a limit of, for example, 2-3 devices.
