List folders bigger 1Mb and list them in descending order

List the ten largest folders inside a recursive folder structure

I missed something like wlan0. Before you know what driver you need to install, you need to figure out which hardware you have. That can be done with the following command:

You receive a large list with lots of information you don’t need. The art is, to find out what is your wifi chip, and there is no general purpose solution, cause different computers might have different hardware. In my case I looked for words like „wifi“, „wireless“, „communication“ and so on. Anyway, the entry I was looking for was this one:

I picked the chipname:

and searched in google, to verify if it was really a wifi chip. H-node is a good source for hardware reseach.

Finally i found here: https://wiki.debian.org/iwlwifi that my chipset was supported.

I extendet /etc/apt/sources.list with the following line:

and performed another two commands:

The following command first removes the iwlwifi module from the limux kernel and then adds it to the kernel.

Now everything should work fine, and you should find in the network-settings your wifi hotspot.
