If you're using a corporate network, you can also set up a proxy server and a static IP address here. To do this, click the gear icon next to the network name or select "Advanced" before connecting.
Problems with a gray or inactive WiFi icon
When the wireless icon becomes gray and unresponsive, it indicates a software or hardware issue. This is a common problem that can occur after an unsuccessful system update or driver failure.
Often, the problem lies in the network module itself. In this case, a simple reboot of the device helps. If the reboot doesn't help, try resetting the network settings, which will restore the connection parameters to factory defaults.

What is Safe Mode?
Safe mode is a diagnostic mode for Android that loads only system apps. This allows you to determine whether software you've installed is causing the problem.
If none of the software solutions help, there's a high probability of a hardware problem. This could be a loose antenna cable or a faulty communication chip on the motherboard.
Advanced settings and optimization
shell Samsung One UI offers a range of tools for optimizing wireless connections. These settings improve signal stability and data transfer speeds in noisy environments.
In the WiFi menu, tap the three dots in the upper right corner and select "Advanced." Here you can change the device's MAC address to a random one, which increases privacy when connecting to public hotspots. You can also select a security protocol.
The Smart Switch feature deserves special attention. It analyzes connection quality and can switch the device to a mobile network if the WiFi signal becomes weak. For reliable operation at home, it's best to disable this feature.
| Parameter | Recommended value | Impact on work |
|---|---|---|
| Frequency range | 5 GHz | High speed, smaller radius |
| MAC address | Random | Increased anonymity |
| Smart Switch | Off (at home) | Connection stability |
| WPS | Off | Network security |
For security-conscious users, it's recommended to regularly update your list of known networks and delete those you no longer use. This minimizes the risk of automatically connecting to compromised access points.
Using WPS and QR codes to connect
Entering a password manually can be tedious, especially if it's complex. Modern smartphones Samsung They support alternative authorization methods that significantly simplify the process. One such method is QR code scanning.
