  • ⏱ Customize time-out (or turn it off).
  • 🔒 Enable hidden network (will not be displayed in the list of available ones).

To change your password, click on Password and enter a new combination (minimum 8 characters, only Latin letters and numbers). Avoid simple passwords like 12345678 - they can be easily hacked using specialized applications.

⚠️ Warning: If you enable 5 GHz, some older devices (such as laptops from before 2015 or printers) may not see your network. In this case, go back to 2.4 GHz or select mode Auto.

3. Optimal settings for stable distribution

By default Samsung Galaxy A8 It doesn't use the most efficient parameters for the access point. Here recommended settings for different scenarios:

Scenario Range (GHz) Channel width Time-out Security
Maximum compatibility 2.4 20 MHz Disable WPA2 PSK
Maximum speed 5 80 MHz 10 minutes WPA3 PSK
Battery saving 2.4 20 MHz 5 minutes WPA2 PSK
Games/streaming video 5 40 MHz Disable WPA3 PSK

To change channel width And security type, you will need to install a third-party application, for example WiFi Hotspot Manager (available in Google Play). In the standard settings Samsung These parameters are hidden.

Important: If you are distributing the Internet via a mobile network, disable automatic switching to 3G in the SIM card settings. To do this, go to Settings → Connections → Mobile networks → Network mode and select LTE onlyThis will prevent speed drops when the 4G signal is weak.
