Ubuntu – Cannot enable Wi-Fi


Yesterday my laptop shut down because battery ran out. Next time I turned it on I couldn't enable Wi-Fi. I tried to enable it with:

rfkill unblock all

but it's still not working. Please help.

rfkill list printed this:

0: Toshiba Bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: yes
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: yes

ip link printed this:

    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

Your WiFi and Bluetooth Devices are hard-blocked...

There is a network-switch/button/key on your computer/laptop which could be switched OFF - means that your network hardware is disabled (hard-blocked)...

Find it and switch it ON...
