Re: Why whenever I enable the WiFi interface NM sends a DHCPDISCOVER if still not associate with any AP?

Much better.  So NetworkManager doesn't know that your device is a wifi
device, as you can see near the top when NM detects wlan0 as an ethernet
device.  This is likely because the driver is not reporting the correct
stuff to HAL.  If you look in the output of 'lshal', you should find a
section for 'wlan0'.  Mine looks like:

udi = '/org/freedesktop/Hal/devices/net_00_16_33_33_33_33'
  info.capabilities = {'net', 'net.80211'} (string list)
  info.category = 'net.80211'  (string)
  info.parent = '/org/freedesktop/Hal/devices/pci_8086_4220'  (string)
  info.product = 'WLAN Interface'  (string)
  info.subsystem = 'net'  (string)
  info.udi = '/org/freedesktop/Hal/devices/net_00_16_33_33_33_33'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'net'  (string)
  linux.sysfs_path = '/sys/devices/pci0000:00/0000:00:1e.0/0000:02:02.0/net/eth2'  (string)
  net.80211.mac_address = 96355641140  (0x166f3e6734)  (uint64)
  net.address = '00:16:33:33:33:33'  (string)
  net.arp_proto_hw_id = 1  (0x1)  (int)
  net.interface = 'eth2'  (string)
  net.linux.ifindex = 3  (0x3)  (int)
  net.originating_device = '/org/freedesktop/Hal/devices/pci_8086_4220'  (string)
  net.physical_device = '/org/freedesktop/Hal/devices/pci_8086_4220'  (string)

You can see that "info.capabilities" contains the item "net.80211".
That means that HAL recognizes the device as a wifi device.  You'll
probably need to talk to your distribution's HAL maintainer, and/or the
person responsible for the kernel driver to figure out why it's not
providing the right stuff to HAL.
