[SOLVED] Rf-kill on wifi all of sudden

My "rfkill list" outputs:

0: dell-wifi: Wireless LAN
        Soft blocked: yes
        Hard blocked: no
1: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes

If I use my blocking key, it outputs:

0: dell-wifi: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
1: phy0: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes

So, as I understood, my wifi is dell-wifi (but what phy0 is?). If I go "rfkill unblock 0", it gives me no/no on dell-wifi so I thought I'm fine but I still can't use it:

[sms@latitude-arch ~]$ sudo ip link set wlp2s0 up
RTNETLINK answers: Operation not possible due to RF-kill

[sms@latitude-arch ~]$ ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: wlp2s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
    link/ether a0:88:b4:ca:89:3c brd ff:ff:ff:ff:ff:ff
3: enp3s0: <BROADCAST,MULTICAST,DYNAMIC,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether d0:67:e5:35:49:29 brd ff:ff:ff:ff:ff:ff

It happened all of sudden, possibly after installing connman but disabling connman.service changes nothing (wifi-menu doesn't work either but it did just an hour ago).

This is how Arch welcomes me after some months without it... ;-)

Re: [SOLVED] Rf-kill on wifi all of sudden

[sms@latitude-arch ~]$ connmanctl enable wifi
Enabled wifi

connmanctl> technologies
/net/connman/technology/ethernet
  Name = Wired
  Type = ethernet
  Powered = True
  Connected = True
  Tethering = False
/net/connman/technology/wifi
  Name = WiFi
  Type = wifi
  Powered = True
  Connected = False
  Tethering = False
connmanctl> scan wifi
Error /net/connman/technology/wifi: No carrier

But it's not Connman problem, other ways won't work too:

[sms@latitude-arch ~]$ sudo wifi-menu wlp2s0
Scanning for networks... failed
No networks found

Re: [SOLVED] Rf-kill on wifi all of sudden

My bad. Rf-kill is always about user being a dumbass, right? ;-) Because my BIOS was set to disable WiFi if ethernet cable is connected...
