Hi Jack,

Thanks for reply. I have updated the kernel to latest as your suggestion. But the problem still exist. Now dmesg output is slightly different.

And I found wlan0 actually is connected and got ip address even eth0 is disconnected. But ssh to wlan0 got no response if eth0 is unplug.

After plugin eth0 and eth0 then wlan0 would response to ssh too.

Regards,
Barry

I think this issue is fixed in the latest kernel. Please update to the linux-4.4-latest_4.4.154-98-rockchip and later.

The kernel version should not affect the wifi signal. Could you check if there is other reasons? such as did you put the board in a metal case?
