[Bug 1528534] Re: No wireless connection on computer start


Moshe Caspi, thank you for reporting this and helping make Ubuntu

As per http://www.gigabyte.com/products/product-page.aspx?pid=1764#bios
an update to your computer's buggy and outdated BIOS is available (F5).
If you update to this following
https://help.ubuntu.com/community/BIOSUpdate does it change anything?

For more on BIOS updates and linux, please see

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful. As well, you don't
have to create a new bug report.

Once the BIOS is updated, if the problem is still reproducible:
1) Please provide the output of the following terminal command (not perform an apport-collect):
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
2) Please make a comment specifically advising on if there was an improvement or not.
3) Please mark this report Status Confirmed. If it's not reproducible, please mark this as Invalid.

Thank you for your understanding.

  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:
