Problem with wifi, rfkill

Hi
I have an Lenovo Flex 2 Pro which is running Arch Linux for some years. Usually I have it connected by to Internet by cable. For about 6 months ago I set up to use wifi by the exellent guide in the wiki  https://wiki.archlinux.org/index.php/Wi … figuration. I set it up first manually and then by NetWorkManager. It worked fine on different networks.

A while ago ( 1 -2 months perhaps) I need to use wifi again and the it suddenly didn't work. After some investigation it seems (among other things) be an soft block. However after rfkill unblock wifi networkmanager don't work.

So how do I do to get rid of the soft block permanently? I have tried some of https://bbs.archlinux.org/viewtopic.php?id=169503 but no luck (tried blacklist ideapad_laptop)

[root@archlap1 ~]# rfkill list

0: ideapad_wlan: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
1: ideapad_bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
2: phy0: Wireless LAN
	Soft blocked: yes
	Hard blocked: no
3: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

[root@archlap1 ~]# rfkill unblock wifi

[root@archlap1 ~]# rfkill list

0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: ideapad_bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
2: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
3: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

After
[root@archlap1 ~]# ip link set wlp2s0 up
[root@archlap1 ~]# iw dev wlp2s0 connect OpenWrt
[root@archlap1 ~]# dhcpcd wlp2s0
wifi works again

Some information:
