NetworkManager can't use my wireless card

[Michael]

Binary package hint: network-manager

I use Natty Alpha3 and upgrade everyday.
Wcid can use my wireless but NetworkManager can't (check Enable Wireless, but nothing happened). The LED for wireless is off. The soft swich on keyboard doesn't work.
In 10.10, NetworkManager, LED and soft swich work fine!
My notebook is Acer Aspire One 721 with Broadccom BCM943225HM.
The last line from lspci output is:
06:00.0 Network controller: Broadcom Corporation BCM43225 802.11b/g/n (rev 01)

You system appears to have wireless disabled by the killswitch or rfkill values from the kernel, you can fix this by verify the following things:

- Make sure the file in /var/lib/NetworkManager/NetworkManager.state reads "true" for all three options, especially WirelessEnabled. If you need to change it to true, stop network-manager first, then start it again when done ("sudo stop network-manager", edit the file, then "sudo start network-manager").

- Run the following command "rfkill unblock 0" ; this should lift the rfkill block on your wireless device; you can verify its operation with the "rfkill list" command.

Note, your bluetooth seems to be disabled too, you may want to do "rfkill unblock 1" as well if you want to use it.

Since the soft switch on the keyboard doesn't appear to work, you should file a separate bug about it: you can do so by using the "ubuntu-bug linux" command and describing the issue; the necessarily logs should be attached automatically.

Hi. I have the same problem. In NetworkManager.state all values are true. I've done the rfkill thing and nothing happens:

robert@robert-laptop:~$ sudo rfkill unblock all
robert@robert-laptop:~$ sudo rfkill list
0: acer-wireless: Wireless LAN
 Soft blocked: yes
 Hard blocked: no
1: phy0: Wireless LAN
 Soft blocked: no
 Hard blocked: no
2: acer-bluetooth: Bluetooth
 Soft blocked: yes
 Hard blocked: no
4: hci0: Bluetooth
 Soft blocked: no
 Hard blocked: no

I have an Acer Aspire 1830T-3721.

I'm in the same boat as chila, with an Aspire 1830T-3721. The soft switch doesn't function. The wireless light was on once I enabled the proprietary drivers, but the light turned off once I unblocked with rfkill.

[Expired for network-manager (Ubuntu) because there has been no activity for 60 days.]

[Nicholas Escalona (escalonn)]

Some update in the last 30 days fixed this problem for me. Either the kernel update to 2.6.38-11, or the updates to isc-dhcp-client (4.1.1-P1-15) probably did it.
