I have bought a USB Wireless Adapter made by SignalKing because I broke my laptop's hardware switch of the embedded adapter.
Despite the fact that I can use it on Windows without having any issue, while using Ubuntu (14.10) I get this message:
Wi-Fi Network (Ralink 802.11 nWlan) Wi-Fi is disabled by hardware
switch
But there's no hardware switch on SignalKing.
The green light showing the adapter is working, is on.
Here are some of the commands I used and the output:
sudo rfkill unblock all
But nothing happened
