I recently installed Ubuntu 18.04 on my laptop, at the moment of the installation it didn't ask me for a WiFi connection, and it hasn't worked since then.
Here are some of the commands I have used.
Code:
$ sudo lshw -c network

The network appears unclaimed.
I have seen other cases in which this commands output other options, but in my case, there is only that one.
Finally, there are no additional drivers, even though I am connected with memory that gives me internet.
I'm new in Linux distribution, so I'm really lost with this issue. Thanks in advance.
