5. Operating Instructions
- Accessing Wi-Fi Networks:
Once the adapter is installed, navigate to your computer's network settings or Wi-Fi icon in the system tray/menu bar. The adapter will display available wireless networks.
- Connecting to a Network:
Select your desired Wi-Fi network from the list. If prompted, enter the network's security key (password). The adapter will then establish a connection.
- Dual-Band Selection:
If your router supports both 2.4GHz and 5GHz bands, you may see two network names (SSIDs) – one for each band.
