I've been using Ubuntu for a long time, no problems until a few days ago. I was installing the Arduino IDE through the Ubuntu Software Center and suddenly the installation got stuck displaying "Applying changes". The system won't respond, so I had to shutdown my laptop using the manual interruptor (cutting off the current).
After starting again, a message appeared:
"The network connection has been closed".
From that moment until now, I haven't been able to connect to wifi or bluetooth. I've tried a lot of workarounds I found on forums, but nothing worked. When I click on the networks icon of the top bar I can see the button "Activate wireless" is gone.
I'm sending this question through windows, this is my level of desperation. Any help will be great, thanks in advance guys!
Edit:
I add this output in order to give more info:

lspci | grep --ignore-case net
&lsusb | grep --ignore-case wi
and post the output back into your question. Io parlo l'Italiano e io capisco la spagnola un poacpi=force irqpoll noapictime
toGRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to/etc/default/grub
, it looks like this nowGRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force irqpoll noapictimer"
