    • Right-click on your TP-Link T3U Plus adapter.
    • Select Properties.
    • Go to the Advanced tab.
  2. Key Settings to Consider:
    • Wireless Mode: This setting usually allows you to specify which Wi-Fi standards the adapter should prioritize (e.g., 802.11a/b/g/n/ac mixed mode). Ensure “802.11ac” or “Auto” is selected to take advantage of the fastest speeds.
    • Channel Width (Bandwidth): For the 5 GHz band, you might see options for 20 MHz, 40 MHz, 80 MHz, or even 160 MHz. The higher the bandwidth, the greater the potential speed. For AC1300, 80 MHz is typically optimal for the 5 GHz band. If you experience instability, try reducing this to 40 MHz.
    • Roaming Aggressiveness: This setting determines how quickly the adapter switches to a stronger Wi-Fi signal if it detects one. A higher setting means it will switch more readily, which can be good if you move around a lot, but might cause brief interruptions. A lower setting prioritizes maintaining the current connection.
    • Transmit Power: This controls how much power the adapter uses to send signals. While higher power can increase range, it might also increase interference. For most users, the default setting is appropriate.
    • AP Isolation: Ensure this is disabled if you want to use the adapter to connect to a Wi-Fi hotspot (AP) that also allows other devices to connect to it. If enabled, it prevents communication between wireless clients.

Note: The exact names and availability of these advanced settings can vary slightly depending on the driver version. Experiment cautiously with these settings, making one change at a time and testing the results.
