daniel@debian-laptop:/tmp$ cd
daniel@debian-laptop:~$ sudo rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: dell-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no

Hard blocked: no
Interestingly when I bring down eth1 (the wifi interface), and rfkill
block wifi, it says:
daniel@debian-laptop:~$ sudo rfkill list
1: dell-wifi: Wireless LAN
Soft blocked: yes
Hard blocked: no
So maybe it is actually working, but what makes me worried is that I can
do ifup eth1 and the interface comes up with no problems... On my old
laptop this was not the case and when blocked, all sorts of nasty error
messages would be present.
BTW, the wifi according to rfkill list is still soft block again once I
bring up the interface eth1, remembering that I blocked wifi just before
with rfkill block wifi, (I have not ran an rfkill unblock wifi) command
yet. So ultimately the wifi is working normally even though rfkill says
it's "soft blocked"...

So could I just unload the module to save power?
