Description Jorn Amundsen 2010-12-08 14:59:21 UTC
Description of problem:
After booting and logging into an account, it is impossible to enable wireless in the notebook (Acer Aspire 1830T) by typing <Fn>-<F3> key to toggle wireless. The Fn-F3 keystroke successfully toggles Bluetooth on and off, but the WLAN consistently stays at

  [root@localhost ~]# rfkill list 0
  0: acer-wireless: Wireless LAN
          Soft blocked: yes
          Hard blocked: no

, making it impossible to turn on wireless in KNetworkManager.

Version-Release number of selected component (if applicable):


How reproducible: every time

Steps to Reproduce:
1. boot
2. login
3. attempt to toggle KNetworkManager "Enable Wireless" checkbox
Actual results:

Wireless LAN soft-blocked

Expected results:

Wireless LAN Soft *and* Hard *unblocked.

Additional info:

Similar behavior is reported in Bug 595931 and 597007. In 597007 the problem is tracked to the acer_wmi module wmi alias reading,

  [root@localhost ~]# modinfo acer_wmi
  filename:       /lib/modules/
  alias:          wmi:6AF4F258-B401-42fd-BE91-3D4AC2D7C0D3
  alias:          wmi:67C3371D-95A3-4C37-BB61-DD47B491DAAB

, while the first alias should read *should* read (42fd -> 42FD)


,for consistency with the /sys/class/6AF4F258-B401-42FD-BE91-3D4AC2D7C0D3 directory.

It appears this error is reintroduced in the aforementioned kernels.

Comment 5 manfredgrabherr 2011-10-30 21:35:03 UTC
Not sure this is the same bug, but I just upgraded from kernel- to kernel-, and wireless stopped working, ifconfig does not see my wireless network card. With kernel 14-97, it reports:

eth1      Link encap:Ethernet  HWaddr 68:A3:C4:2C:A7:20  
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::6aa3:c4ff:fe2c:a720/64 Scope:Link
          RX packets:518127 errors:0 dropped:0 overruns:0 frame:78421
          TX packets:264645 errors:6 dropped:0 overruns:0 carrier:0

          RX bytes:776220522 (740.2 MiB)  TX bytes:20699298 (19.7 MiB)

With 14-100, there is nothing listed. It's a Dell inspiron N7010 laptop, not sure about the exact wireless network chipset. I reverted back to the old (97) kernel for now and it works just fine. Any help is appreciated.
