Hi,

it seems the driver gets confused by the MAC address change: 

  kernel: [    9.476452] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
  kernel: [    9.482897] esp_op_add_interface interface 0 requested by - 
NetworkManager - 231
  kernel: [    9.490304] esp_op_add_interface STA
  kernel: [    9.495224] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
  NetworkManager[231]: <info> [1511649658.0166] device (wlan0): set-hw-addr: 
set MAC address to 26:2F:1A:C7:05:F4 (scanning)
  kernel: [    9.504764] esp_op_add_interface interface 2 requested by - 
NetworkManager - 231


Perhaps you can try disabling the randomization of MAC address during
scans; add the following to /etc/NetworkManager/NetworkManager.conf
and restart the service.

[device]
wifi.scan-rand-mac-address=no
