Unstable wifi connection

Hello everybody,

A couple of days ago I installed Kali linux on my second drive and now i have a dual boot system with windows 10 and Kali linux. But my wifi keeps dropping (maybe even disconnecting) and going up, during this wifi droppings I cant load any pages on the internet. I have tried a couple of things I have found on the internet of people I thought had the same problem, but I still have the problem.
So first some observations I made:
  • This problem only occurs when I am on Kali linux, when I boot from windows 10 I have no problem with the wifi
  • When I am using a usbwifi adapter on Kali linux this problem does not occur, so that is my solution to this problem now
  • last night I had no problem at all, which made me think that maybe the problem has to something to do with interference of other wifi devices or modems in the area, I think this because in the night there is allot les wifi traffic in the air ( maybe it has nothing to do with this )​
So Kali linux is using Network manager and these are the things I have tried so far:
Code:
echo "options ath9k nohwcrypt=1 blink=1 btcoex_enable=1" >> /etc/modprobe.d/ath9k.conf
Code:
modprobe ath9k 11n_disable=1
I have gone to /etc/NetworkManager/NetworkManager.conf and changed with nano managed=flase to managed=true
further more I have put ipv6 connections to disabled on the GUI for this specific wifi connection.
None of these things seemed to help, so i guess none of these things were the problem.

here some info:

I have looked for the code (code=17) and I believe it means:
17. Association denied because AP is unable to handle additional associated stations. Will happen if you run out of AIDs on the AP; so try associating a large number of stations.

Code:
journalctl -b 0 /usr/sbin/NetworkManager

I cant find what reason -4 means

So this is how far I have come to to understanding and fixing the problem. This is my first experience with linux so I am not to experienced with the terminal.
any help is welcome!

If the Internet connection is still unstable, check the cable modem to see if it feels hot. When a modem overheats, it can cause the Internet connection to be unstable. If this is the case, turn it off and let it cool down, then try turning it on and testing the Internet connection.
