Re: nm in different linux distributions - ppp versus qmi-wwan

[Thomas Schäfer <tschaefer t-online de>]

Hi,


That was the problem. option has occupied to much resources.
After removing option and qmi_wwan and adding them in reverse order 
everything works as expected.
So now I have to find the right people of manjaro.. or they read this 
thread accidentally.

Thank You very much!!

Thomas
