☑️ Pre-launch check
Once you enable the slider, the system will automatically create a network with a name containing the model of your device, for example, Redmi 8TBy default, the network can be open or protected with a default password, which is best changed for security. Below is a table with the main settings you should check immediately after activation.
| Parameter | Recommended value | Description |
|---|---|---|
| SSID (Network Name) | Unique name | Allows you to easily identify your network among neighboring ones |
| Security | WPA2-Personal | Optimal balance between compatibility and data protection |
| Password | Complex (8+ characters) | Protects against unauthorized access by third parties |
| Range | 2.4 GHz | Provides better compatibility with older devices |
Setting up security and network settings
The security of your personal network is a priority. Encryption standard WPA2 is the most common and reliable option for mobile hotspots. Using an open network or the outdated WEP protocol makes your transmitted data vulnerable to interception by hackers.
Create a strong password that includes mixed-case letters, numbers, and special characters. Avoid obvious combinations, such as birth dates or sequences of numbers. The password must be entered accurately on connected devices, taking into account the case of the characters.
You should also consider hiding the SSID if you don't want the network to appear in the general list of available connections. However, keep in mind that this isn't complete protection, as experienced users can detect hidden networks using specialized software. For home use, simply installing password.
⚠️ Note: The security settings interface may change with MIUI updates. If you don't see this setting, check the "More" or "Advanced settings" section within the hotspot menu.
Choosing a Frequency Band: 2.4 GHz vs. 5 GHz
Redmi 8T supports operation in various frequency ranges, which gives the user flexibility in customization. Range 2.4 GHz It has a longer range and penetrates walls better, but it is often overloaded with signals from neighboring routers and household appliances, which can reduce speed.
The 5 GHz band offers higher data transfer rates and is less susceptible to interference, but has a shorter range. If you're in a dense urban area or apartment building, switching to 5 GHz can significantly improve connection stability.
The choice of band depends on the requirements of the devices being connected. Older laptops or tablets may not support the 5 GHz frequency, so in these cases, you'll have to revert to the 2.4 GHz standard. Check the specifications of your devices before changing this setting.
How does range affect battery life?
Using the 5GHz band may consume slightly more power due to the higher data processing speed, but the difference in battery life of the Redmi 8T will be negligible under normal use.
Managing connected devices and limits
System Android Allows you to control who is connected to your access point. The access point management menu displays a list of all active clients with their MAC addresses. You can manually block unwanted devices, preventing traffic theft.
An important feature is setting a connection limit. You can limit the number of simultaneously connected devices to, for example, three or five. This will help maintain internet speed for your primary devices and prevent overloading your smartphone's processor.
- 📱 Check the list: Regularly review the list of connected clients.
- 🚫 Block: Tap on a device to disable it or add it to the blacklist.
- ⏱ Timer: Some MIUI versions allow you to set a timer for automatically turning off the hotspot.
