Hello, I have a Complex 11t tablet with this wireless card on USB. The kernel driver supports it, but even at its best, it doesn't work at full speed and frequently loses connections, whereas Windows 10 doesn't have any problems. I'd be happy to test and debug code, and provide whatever help I can to improve the driver for this device. Here is some system information. The kernel I'm currently using is version 4.13.0 on Ubuntu 17.10.

Why are you loading BOTH rtl8xxxu and 8723bu? The conflict between them will cause all kinds of problems.
