Andrei,

Are you certain this is working in resinos currently?  I modified my
config to use NetworkManager and it has similar behavior.  The "nolinked
power save" messages are evidently debug so I ignore them but I do get
the following:

[  246.050000] RTL8723BS: rtw_set_802_11_connect(wlan0)  fw_state =
0x00000008
[  246.145000] RTL8723BS: start auth
[  246.150000] RTL8723BS: auth success, start assoc
[  249.225000] RTL8723BS: rtw_set_802_11_connect(wlan0)  fw_state =
0x00000008
[  249.420000] RTL8723BS: start auth
[  249.430000] RTL8723BS: auth success, start assoc
[  252.885000] RTL8723BS: rtw_set_802_11_connect(wlan0)  fw_state =
0x00000008
[  253.105000] RTL8723BS: start auth
[  253.115000] RTL8723BS: auth success, start assoc
[  257.075000] RTL8723BS: rtw_set_802_11_connect(wlan0)  fw_state =
0x00000008
[  257.305000] RTL8723BS: start auth
[  257.315000] RTL8723BS: auth success, start assoc
[  268.225000] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready

and then no connection.  I even disabled encryption temporarily on my
wifi and was unable to connect.

I tried to build a resinos image for CHIP to try it but was
unsuccessful.  Do you have any binaries I can try?

Also, I installed the stock debian from flash.getchip.com and it was
able to connect so my hardware seems solid.
