I want to learn about this things, what do i search for.

Why do people come with broadcom-wl? Funny enough…

However on the net there are lot of issues with the 11N on certain routers, which mix it and powersaving, which reduce the performance.

You can try this:

First disable wifi powersaving:

echo "wifi.powersave = 2" | sudo tee /etc/NetworkManager/conf.d/wifi-powersave.conf


NM_SETTING_WIRELESS_POWERSAVE_IGNORE  (1): don't touch existing setting

:notebook: modprobe is a tool for loading and unloading modules (drivers) and adding parameters.

Parameter 1:

sudo modprobe -rv iwlwifi
sudo modprobe -v iwlwifi 11n_disable=8
sudo systemctl restart NetworkManager

Parameter 2:

sudo modprobe -rv iwlwifi
sudo modprobe -v iwlwifi 11n_disable=1
sudo systemctl restart NetworkManager

Combine several Parameters:

sudo modprobe -rv iwlwifi
sudo modprobe -v iwlwifi 11n_disable=1 swcrypto=1
sudo systemctl restart NetworkManager

More Parameter to try:

modinfo iwlwifi | grep -i "parm:"

If something works, then create a textfile here: /etc/modprobe.d/somefile.conf with a content like that:

options iwlwifi 11n_disable=1 swcrypto=1

That is then permanent.

So searching for the device you may find what you need

While the following is for a thinkpad - I am fairly certain the instructions for wifi can be applied to a dell as well
