How to disable Wifi Power Save on Kali Linux

Question

I am running kali with virtualbox and my wifi receiver is a usb adapter which is Asus N10 Nano. I made the settings on virtualbox for making the vb recognize my usb wifi adapter. It works but after like 5min my internet drops. Especially during the updates. I figured it out its because the "Wifi Power Save" option is on. I turned it off and tried again. When i turned it off my wifi turned off at the same time. I tried to turn my wifi on but the Wifi Power Save option turned on itself automatically. The usb icon on bottom is like red-green. It needs to be blinking green to work correctly. If i can turn off the Wifi Power Save mod permamently hopefully its gonna be blinking green. I searched for it, I did almost everything like creating directory as /etc/pm/power.d/wireless and editing the file wireless by these commands:

#!/bin/sh
/sbin/iwconfig wlan0 power off

Then i gave the permission -x for it. It didnt work. Sorry if I had mistake while I was writing this. Thanks for helping!

It didn't work. In the end sudo depmod rtl8192cu output was: depmod: FATAL: rtl8192cu: not absolute path.

You have to answer to posts in the comments. By sheer luck, I was the one approving your edit.My mistake, it should be modprobe. Nevertheless, if it does not work, reboot it. Edited the answer. — Rui F Ribeiro, Jan 28 '16 at 21:41
the pen does not come up in lspci, it has to be lsusb. nevertheless already found the chipset in google — Rui F Ribeiro, Jan 28 '16 at 21:48

The Asus N10 Nano has the Realtek 8192CU chipset. I advise to configure the loading of the required kernel modules using the following procedure.

Create the file sudo vi /etc/modprobe.d/rtl8192cu.conf, with:

options rtl8192cu  rtw_power_mgnt=0 rtw_enusbss=1 rtw_ips_mode=1

Then do:

sudo rmmod rtl8192cu
sudo modprobe rtl8192cu

If the modprobe does not work, restart the server.

Nevertheless, be warned the Asus N10 Nano is using the rtl8192cu which is a notoriously cheap and buggy chip, notoriously in energy management.

Please do read my answer in this thread, talking also about Asus and the same chipset.
