cmst broke my internet connection
Today, out of sheer curiosity, I installed cmst application. It turned out to be a huge mistake.
Because it was not useful to me, I removed cmst immediately after installing it. I could not have imagined that this small experiment will cause me so much headache.
Now I have no internet access anymore. My PC does connect to the router, I can access my NAS directories and files, but nothing form the WWW gets through. There is a question mark in the notification area, where WiFi icon is supposed to be.
I managed to find this command line workaround, that enables the WWW access:
Code:

[root@E7440-DELL home]#
Still, every time I boot my PC, no internet...
Each time I must use `dhclient wlp2s0` in order to get the internet access.
Does anyone know what got broken, and how to fix it?

I just discovered that google search on cmst gives a lot of options, such as: - Centre for MicroSystems Technology
- Certified Manager of Software Testing
- Certified Master Safe Technician
- Cornwall Music Service Trust
- Computational Methods in Science and Technology
- and many others...
So, in case you don't know which cmst is to blame. It is none of the above, but this one:
Code:
[root@E7440-DELL home]# dnf info cmst
