[Bug 919885] Re: Cannot connect to wireless network after mac address change

 

On further inspection I changed the security of the network to Open. No
filtering of any kind.

It hung for a minute but ended up connecting with a spoofed mac.

In dmesg there is this instead of the deauth reason 2, which is quite
odd: [   91.553210] wlan0: deauthenticating from 00:1c:df:a2:b9:28 by
local choice (reason=3)

WEP connects fine, no problem at all.

WPA/TKIP has the same issue [  593.726862] wlan0: deauthenticated from
00:1c:df:a2:b9:28 (Reason: 2)

WPA2/AES has same issue as WPA/TKIP

Title:
  Cannot connect to wireless network after mac address change

Status in “network-manager-applet” package in Ubuntu:
  New

Bug description:
  I'm hoping the dmesg was included with this bug report.

  Connecting to a wireless network with my current configuration works
  perfectly.

  After changing my mac address, trying to connect back to the same
  network results in it just sitting there looking like it's connecting.

  In dmesg it appears to be getting authenticated for some 'reason 2'.

  I think this worked fine in 10.10,  I have tried Linux Mint 12, Ubuntu
  11.10 and Lubuntu 11.10 and they all have the same issue.

  I execute

  sudo ifconfig wlan0 down
  sudo macchanger -A wlan0
  sudo ifconfig wlan0 up

  (same bug happens when I put a new mac address in the cloned mac
  address field too)

  ifconfig shows it has the new mac
  when I try to connect it just appears to hang with some juicy info in dmesg.
