3. Plug in the Adapter:
   • Insert the DWA-185 adapter into an available USB 3.0 port on your computer. The adapter is also compatible with USB 2.0 ports, but for optimal performance, a USB 3.0 port is recommended.
4. Verify Installation:
   • After plugging in the adapter, your operating system should detect the new hardware. A small LED indicator on the adapter may light up or blink, indicating activity.
   • Check your computer's Device Manager (Windows) or System Information (Mac/Linux) to confirm that the DWA-185 adapter is recognized and drivers are installed correctly.

6. Operating Instructions

Once the adapter is installed, you can connect to a wireless network.

1. Connect to a Wireless Network:
   • Windows: Click the Wi-Fi icon in the system tray. Select your desired wireless network (SSID) from the list and click 'Connect'. Enter the network security key (password) if prompted.
   • Mac OS: Click the Wi-Fi icon in the menu bar. Select your desired wireless network (SSID) and enter the password.
   • Linux: Use your distribution's network manager to scan for and connect to wireless networks.
2. Selecting a Frequency Band (2.4 GHz or 5 GHz):
   • If your router broadcasts separate SSIDs for 2.4 GHz and 5 GHz bands (e.g., 'MyNetwork_2.4GHz' and 'MyNetwork_5GHz'), you can choose which band to connect to.
   • The 5 GHz band offers higher speeds and less interference but has a shorter range. The 2.4 GHz band offers better range but lower speeds and more interference. Choose the band that best suits your needs.
3. Security:
   • The DWA-185 supports WPA3, WPA2, and WPA encryption protocols. Always connect to networks using the strongest available security (WPA3 or WPA2) to protect your data.
