Hello Joey,

here are some findings with acer_wmi. I execute the following steps from 
top to bottom, and only after the last step my wifi works. After each 
step you find the output of "rfkill list":

after booting (no ideapad_laptop, no acer_wmi):
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes

after loading acer_wmi (wifi switch is on):
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: acer-wireless: Wireless LAN
	Soft blocked: yes
	Hard blocked: no

after switching off:
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: acer-wireless: Wireless LAN
	Soft blocked: yes
	Hard blocked: no

switching on again:
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: yes
2: acer-wireless: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
3: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

after removing acer_wmi with modprobe -r:
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
3: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

Now wifi networking can be used!
The optimal solution would be to have ideapad_laptop make all 
initialisations so wifi can be used after booting with no manual steps 
necessary.
