[Touch-packages] [Bug 1528009] Re: hard blocked rfkill status of second WiFi adapter is incorrectly handled
As a side note: after reading a lot of different forum topics I found
the following method how to change "Hard blocked: yes" state to "Hard
blocked: no" state of the "rfkill list" output.
On Toshiba Satellite C50-B-19U laptop, start from powered off state.
Laptop batter can remain in the laptop (it is not removeable anyway
easily in case of this model). AC adapter can remain plugged. Push the
power button and keep it pressed. The laptop will not power up until
power button is held pushed. After about 10 seconds the white LED
showing that the AC adapter is connected properly is goes off and blinks
once. After this the white LED is on again. The power button was kept
pushed until 30 seconds is elapsed (but I'm not sure if it is needed at
all, the blink of the white LED seems to be a good feedback.) When the
power button is released the laptop keeps turned off. Pushing the power
button again shortly starts the laptop and the following BIOS message
appears:
RTC battery is low
Press Enter to set Date/Time.
[Enter]
After this BIOS Setup appears ("TOSHIBA Setup Utility") and System Time
starts from 00:00:00, System Date starts from 01/01/2014. Set the time
and date manually and then boot Ubuntu. The "rfkill list" shows now
"Hard blocked: no"
root@ubuntu:~# rfkill list
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
root@ubuntu:~# root@csuka-ubuntu:~# rfkill list
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
root@ubuntu:~#
I don't know, however, how to reproduce the original state of this bug
report: how to enable "Hard blocked: yes" state again on the internal
WiFi adapter.

Title:
hard blocked rfkill status of second WiFi adapter is incorrectly
handled
Status in network-manager package in Ubuntu:
New
Bug description:
Toshiba Satellite C50-B-19U laptop contains a WiFi adapter handled by
ath9k kernel driver. This WiFi adapter got disabled somehow and
"rfkill list" reports that it is in "Hard blocked: yes" state.
(Pressing the WiFi button only changes the "Soft blocked" state.)
I tried to quickly work around this problem by plugging a second WiFi
adapter to an USB port. This second WiFi adapter is reconginsed and
"rfkill list" reports to that adapter that it is "Hard blocked: no"
state. However nm-applet shows for both adapter "Wi-Fi is disabled by
hardware switch". The same thing happens with the "nmcli radio"
output.
I have done some investigation and found that:
- if only one WiFi adapter is in the system and it is "Hard blocked: yes"
state then "nmcli radio" reports WIFI-HW disabled, that's OK
- if two WiFi adapters are present in the system and one of them is "Hard
blocked: yes" state and the other is "Hard blocked: no" state then "nmcli
radio" reports WIFI-HW disabled. Expected would be that only the had blocked
WiFi adapter is disabled, the other one which is "Hard blocked: no" shall still
work. nm-applet lists the two adapter separately anyway but both seems to
reported as "Wi-Fi is disabled by hardware switch" which is not the correct
situation in the system
- if the first WiFi adapter's kernel driver is unloaded then the second WiFi
adapter remains in the system only with "Hard blocked: no" state and that
adapter starts to work. "nmcli radio" reports that WIFI-HW is enabled.
