Title:
  [natty regression] Can not make working Ad-Hoc Wifi Networks any more

Status in “linux” package in Ubuntu:
  Confirmed
Status in “network-manager” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: network-manager

  I use 2 Laptops, one has Internet access over Ethernet and I share the connection to the second laptop.
  Laptop#1: Sony VAIO F13, natty, has Ethernet access
  Laptop#2: Acer Aspire 4810, natty

  Steps to reproduce:
   * On Laptop#1 Connect Ethernet Cable and  Create new Wifi AdHoc Network
      - NetworkManager -> Edit Connections -> Wireless -> Add -> SSID "test" -> Mode "Ad-hoc" -> IPv4 Settings -> "Shared to other computers" -> save.
   * Notification says. "test -- connection established"

  What I expected to happen:
   * On Laptop#2: Wifi "test" appers, connect, and its online.

  What I happened instead:
    * On Laptop#2 nothing appears. 

  What happened when Laptop#1 has booted on a Maverick liveCD:
    * Connection on Laptop#2 works perfectly.

  I can reproduce this when everything runs on liveCDs to avoid possible
  settings/installation issues.
