Hi @aitorus,
Native USB cable connection is not yet supported in the current spacedesk BETA version.
For now, you can do USB tethering connection (if your android device supports it).
To setup a USB tethering connection, please refer to the Performance Tuning -> Network Bandwidth -> USB Tethering chapter in the user manual https://www.spacedesk.net/user-manual/#item_509.
FYI: Native Android USB cable connection will be available very soon.
Hi @johnliem,
Wired connection tends to have better performance than wireless connection (that goes through the router).
The fastest option is always a direct connection via network cable or USB cable (by USB tethering).
Please refer to the Performance tuning chapter in the user manual https://www.spacedesk.net/user-manual/#item_505.
