[Bug 1528534] [NEW] No wireless connection on computer start
Public bug reported:
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:
