I recently installed Linux Mint on my Dell Inspiron 3551 and everything works fine, except the WiFi network adaptor. I do not have an Ethernet port in my laptop and have to heavily rely on WiFi. Now I have tried to install the driver, and after using the command 'lspci' it shows that the network adaptor for WiFi is present. Yet 'lshw' shows that 'this device hasn't been claimed'. How do I claim this device? Or rather...how do I get my WiFi adaptor started?
I have used the following commands:
lshw -c net
