دستورالعمل های عملیاتی
اتصال به شبکه بی سیم
After successful installation, you can connect to an available Wi-Fi network.
- Click on the network icon in your computer's system tray (usually in the bottom-right corner for Windows, top-right for Mac OS).
- لیستی از شبکههای بیسیم موجود ظاهر میشود. شبکه مورد نظر خود را انتخاب کنید.
- روی «اتصال» کلیک کنید و در صورت درخواست، کلید امنیتی شبکه (رمز عبور) را وارد کنید.
- The adapter will establish a connection to the chosen network.
Dual Band Operation (2.4GHz and 5GHz)
The COMFAST CF-912AC supports both 2.4GHz and 5GHz frequency bands. The 2.4GHz band offers wider coverage, while the 5GHz band provides faster speeds and less interference, ideal for streaming and gaming.
- If your router broadcasts both 2.4GHz and 5GHz networks (often with different names, e.g., "MyWiFi_2.4G" and "MyWiFi_5G"), you can choose which band to connect to.
- For optimal performance in close proximity to the router, connect to the 5GHz network.
- For better range and penetration through walls, connect to the 2.4GHz network.
