You report several problems but in one report we should track exactly one problem. It seems that the most important problem is that NM always enables an interface you never want to use; so I have adjusted the title accordingly. If there are other issues you think should be pursued, please search for existing reports and add comments there or open new reports, one per issue, as appropriate.
** Summary changed: - Incorrect handling of multiple wireless nics. + NM does not remember that an interface has been disabled -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/798893 Title: NM does not remember that an interface has been disabled Status in “network-manager” package in Ubuntu: New Bug description: Binary package hint: network-manager I have two wireless devices on my laptop. The internal wireless device is so bad i can't get a signal if i am on-top of a wireless AP. I have a USB wireless nic plugged in. Every time I boot the machine both wireless devices are enabled and packets attempt to route through the internal device (which will never work). You can't assume that a list of wireless nics is a simple list and just pick the first one. The wireless device with the best signal should be chosen in this case. However the bigger problem here is that network managers for other operating systems (osx,windows...) store a users "state". If I disable the internal wireless nic it should stay disabled. If I connect to a secure network it should store that key and never ask for it again. (I hate the popup that has my obscured password and i just click "ok", thats just annoying and a worthless dialog box.) Also they have firewalls(!), why can't i adjust my firewall settings per network interface?
