i have the same problem, the wifi works for a lot of days and sometime disconnects. restart networkmanager or reconfig the wifi do not work, only a reboot works for me. as workaorund i have pluged in an usb wifi dongle and hope this connection is stable. my monitor output http://ix.io/NDw

oh, I did not see that. I will try that, thanks

any news from the driver? So my project ist migrated to the tinkerboard with an ttl to rs485 adapter, but I would be happy if the usb adapter would work

no ch3xx.ko with "find /lib/modules/ -name "ch34*ko""

Hi Igor, thanks for the reply, but I do not quite understand. I am not a specialist in the ux world, but only compile the kernel is not enough? As I see it is missing the driver for the CH340 / CH341 or even only the assignment of the Vendor / Device ID to this driver. I do not know how I can check whether the driver is available or how I can include. There is a driver for the converter, but only for kernels 2.x and 3.x http://www.wch.cn/download/CH341SER_LINUX_ZIP.html regards Marco

Hello, i will move my project from RPI2 to tinkerboard. I have 2 Serial Converter, USB to RS422 and USB to RS485, both working on the PI. On the Tinkerboard with "ARMBIAN 5.33 stable Ubuntu 16.04.3 LTS 4.13.3-rockchip" runs only the RS422, the RS485 (Vendor 1a86) is not available as /dev/ttyUSB. What can i do?
