- 🔍 Find the name of your router (SSID) in the list, which is usually indicated on a sticker on the bottom of the device.
- 🔑 Enter your password, observing the case of the letters (upper and lower case letters matter).
After entering the security key, the system will automatically verify the information and establish a connection. If everything is successful, "Connected" will appear next to the network name, and a corresponding indicator will appear in the status bar. In some cases, especially with older routers, the phone may prompt you for advanced settings before connecting.
⚠️ Warning: If you are in a public place, avoid connecting to open networks without password protection, as your data may be intercepted by malicious users.
It is important to note that modern encryption standards WPA3 may not be supported by older router models. In this case, the phone will attempt to use an older protocol, which sometimes causes conflicts.

Go to your Wi-Fi settings and scroll down to "Add network" or "Other network." In the menu that opens, enter the network name (SSID) in the appropriate field. Next, select the security type your router uses, which is most often WPA/WPA2-Personal.
| Parameter | Description | Importance |
|---|---|---|
| SSID | Network name, case sensitive | Critical |
| Security | Encryption type (WPA2, WPA3) | High |
| Password | Network access key | Critical |
| Hidden | Network visibility flag | Average |
After filling in all the fields, click the "Save" button. The phone will actively search for the hidden network with the specified name and attempt to authenticate. If the information is entered correctly, the device will connect and remember the network for automatic future connections.
