Ubuntu – How to get wifi to work? HP Pavilion x360

14.04drivershprealtek-wirelesswireless

Have a HP Pavilion x360 13-s000. Can't seem to get the wifi working on either Ubuntu 14.04 and 15.04. Did multiple Google searches, but now I'll just ask. The wifi card is a Realtek RTL8723BE [10EC:B723]. Can someone help me get this working?

This is what it said after running lshw in terminal

*-network DISABLED

After running rfkill unblock all it still shows wireless is softblocked.

rfkill list all

0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

UPDATE
I have followed the solution here, however the issue remains unresolved. My wifi has never once worked yet, if that helps at all.

The output of rfkill list all is now

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

The Wireless LAN and acer-wireless seemed to have switched positions.

Solution: buy a different laptop……

I don't run Ubuntu (Fedora) but had the same problem (wifi not switching on) on an HP PAV x360 and also had the same symptoms, namely:

1: acer-wireless: Wireless LAN
Soft blocked: yes

You need to blacklist the acer_wmi module (it never should have been loaded!)

[root@localhost ]# lsmod | grep acer

Edit (or create if it doesn't exist) /etc/modprobe.d/blacklist.conf

Add the following lines

# Disable acer_wmi as it breaks wifi on this model
blacklist acer_wmi

Now unload the module (it will be blacklisted on the next boot so you only need to unload once)

[root@localhost ]# modprobe -r acer_wmi

Enjoy your working wifi!
