That’s the same problem i have.
The workaround i have adopted until the present time, is using only USB 2.0 devices, or if i need to connect a USB 3.0, i will only do it when i am not needing the Wifi connecting… because it’s going to drop!
Also the Wifi tops speed is around 45Mbits, but it drops to around 20Mbits when using a Bluetooth mouse with the built-in cube Bluetooth connection.
I guess the Wifi is the biggest drawback of this device.
Does anyone here has replaced the Wifi card?
