| Parameter | Recommended value | Description of influence |
|---|---|---|
| Wireless Mode | 802.11 b/g/n/ac | Specifies the communication standards that the adapter supports. |
| Roaming Aggressiveness | Medium | Frequency of searching for the best access point when the signal is weak. |
| Power Saving Mode | Maximum Performance | Disables power saving for a stable signal. |
| Preferred Band | No Preference | Preference for 2.4 GHz or 5 GHz band. |
Pay special attention to the "Power Management" tab. Uncheck "Allow the computer to turn off this device to save power." Windows system Sometimes it turns off the Wi-Fi module too aggressively to save battery life, and then fails to turn it on correctly. This is a common cause of spontaneous connection drops.
WLAN AutoConfig Service and System Processes
A special system service in Windows is responsible for detecting and connecting to wireless networks. If it's stopped, the Wi-Fi icon may disappear, and the list of available networks may stop updating. To check its status, click Win + R, enter the command services.msc and press Enter. Find "WLAN AutoConfig" in the list.
⚠️ Attention: If the service is stopped, simply starting it may not be enough. You need to change the startup type to "Automatic" so that the system automatically activates the module after each reboot.
