Hi,
I am working on a Lenovo Yoga Pro 3. This device does not have any physical
rfkill switch. In addition, it has a Broadcomm 4352 wireless device.
I am using the proprietary Broadcomm wireless device driver as there is
currently no open source driver available.
After booting the Broadcomm wireless driver is not loaded. ifconfig -a does
not display any wireless device. The status of rfkill is as follows:
rfkill list all
0: ideapad_wlan: Wireless LAN
Soft blocked: yes
Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: yes
You see, that there is a woreless LAN device reported with a hardware rfkill
switch.
When insmoding the Broadcomm driver, the rfkill status is:
rfkill list all
0: ideapad_wlan: Wireless LAN
Soft blocked: yes
Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
Soft blocked: yes
Hard blocked: yes
7: phy1: Wireless LAN
Soft blocked: yes
Hard blocked: no
8: hci0: Bluetooth
Soft blocked: yes
Hard blocked: no
Now, after calling rfkill unblock all, the soft blocked status is no, but the
hard blocked is still yes for the ideapad_wlan. This implies that the
NetworkManager keeps the Broadcomm phy1 device disabled. When I rmmod the
ideapad_laptop device driver, only phy1 and hci0 are left and NetworkManager
activates them to work normally.
When insmoding the ideapad_laptop again, I see the hard blocked setting for
both ideapad_* devices is "no", which implies that I still have network
connection.
I am wondering why is there an ideapad wlan rfkill hardware switch found after
boot, but after rmmod and insmod it is not found any more.
Thanks
