The problem is that my wifi connection breaks all the time irregularly, in the span of after 5 minutes and sometimes after 30 minutes. When this happens I have to sudo service network-manager restart.
This is my wireless info:

I use an MacBook Pro late 2012 with Ubuntu 18.04 and i3 wm. Thanks for any help. Additionally the wifi breaks every time after suspend and I do not have a fix for this neither.
