I have a photovoltaic system connected to 2.5ghz wireless via a Wi-Fi dongle, of which I've attached a photo. It often happens that even though the Wi-Fi dongles are connected to the Deco X50 (they're one meter away with no obstacles), they turn off. Therefore, they're theoretically connected but aren't downloading data to check the system's performance. It's as if they don't have an Internet connection. So, to see them again in the system's specific app, I have to restart the main Deco or sometimes just the Deco X50 to which they're connected.

Question: Could the "Fast Roaming" and "Beamforming" Wi-Fi options be causing problems? I've currently disabled Beamforming, and the connection seems to remain stable.
Do you think I should disable both of them, or is there another option I can enable/disable?
Thanks
