  No wireless connection on computer start

Status in linux package in Ubuntu:

Bug description:
  I use tp-link wn723n usb dongle. When I start the computer I am not
  connected automatically to the router but the hardware is recognized.
  It looks like the problem is that I get a wrong MAC :

  kernel: [ 32.481663] MAC Address = 00:e0:4c:81:88:02

  which looks like a combination of the first part of the serial number
  of the dongle: 00e04c, the chip: 8188 and and an index number: 02.

  I have to remove the dongle  and insert it in order for the wireless
  connection to work. Then I get the correct MAC:

  kernel: [ 449.752527] MAC Address = c4:e9:84:0c:cb:af

  It looks like the problem starts here:

  kernel: [ 56.946579] r8188eu 1-2:1.0 wlan1: renamed from wlan0

  even though I have:

  # USB device 0x:0x (r8188eu)
  SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="c4:e9:84:0c:cb:af", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"

  # USB device 0x:0x (r8188eu)
  SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:e0:4c:81:88:02", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan1"

  If I reboot the computer at this point that I have a connection to the router, magically  I am automatically connected again to the router.

  Here are 2 same issues with wrong MACs and the same chip:
