Thank you for reaching out. I understand that you are experiencing Internet dropouts specifically when connecting to a Citrix workstation through your Deco Mesh network. Your PC is connected to a satellite Deco unit, and you have already tried disabling beamforming and fast roaming. The main Deco is in a different room, so you cannot connect your PC directly to it, and your ISP has already checked the line multiple times.

Here are some steps you can follow to help resolve these dropouts:

1. Compare with Other Devices:
• If possible, try using another device on the same satellite Deco to see if the issue is specific to your PC or affects all devices.

2. Check QoS Settings:
• Open the Deco app and go to MORE > QoS. Make sure the bandwidth settings match your actual subscribed Internet speed.

3. Client Device Settings:
• In the Deco app, find your PC in the client list. Ensure that 'Speed Limit' is disabled and that 'Connection Preference' is set to 'auto' (the default setting).

4. Parental Controls:
• Check the 'Parental Control' section in the Deco app to ensure your PC is not restricted by any profile.

5. Satellite Deco Signal Strength:
• Make sure your satellite Deco has at least 2 bars of signal strength. If it only has 1 bar, try moving it closer to the main Deco to improve stability.
• If your satellite Deco is connected via Ethernet backhaul, double-check the Ethernet cable connection. Ideally, connect the main and satellite Deco units directly without any switches, and confirm that 'Ethernet Backhaul' is displayed in the Deco app.

6. Wi-Fi Band and Network:
• Ensure your PC is connected to the nearest Deco unit with a strong signal, and if possible, use the 5GHz or 6GHz band instead of 2.4GHz, as 2.4GHz is not recommended for latency-sensitive tasks like Citrix.
• Make sure your PC is connected to the main network, not the guest or IoT network.

7. Additional Suggestions:
• If you have the option, try relocating the satellite Deco or your PC to see if a different position improves the connection.
• If you use VPN or security software, temporarily disable them to see if they affect Citrix connectivity.

If you continue to experience issues after these steps, please contact TP-Link support and provide the results of the above troubleshooting. This will help us assist you further.
