Hi guys, this is my first post in the forum and I hope to be welcomed

I have an old macbook (Mid 2010), I installed Kali Linux, the network adapter driver, and it worked properly.

Some days ago I was trying to learn Linux and I did some commands:
apt-get update
apt-get upgrade

To be honest it took a long time, and even the wallpaper changed after that.


Now the WiFi is not working. I tried to reinstall the drivers but it looks are already installed.

This is some information:

wlan0 IEEE 802.11 ESSIDff/any
Mode:Managed Access Point: Not-Associated Tx-Power=23 dBm
Retry short limit:7 RTS thrff Fragment thrff
Encryption keyff
Power managementff

Code:
iwlist scan | more
wlan0 No scan results
-

I have been Googling and trying different things, but honestly I don't where to look at it.

Thanks.
