I would like to ask why antergos does not support connections via 3g usb modem (huawei e3131 - i. t. case). WiFi works fine but I use almost always a usb modem. In other distributions this problem does not exist (ubuntu - mint, centos). I was very happy with the antergos, but not too long. Large database of software, rolling release, etc.
I do not know how it happened that the connection was getting worse. Finally I reinstalled. Both KDE and cinnamon could not connect via modem. Installation ant. Cinnamon was using a modem. But after removing the modem from the USB and restarting, the connection disappeared from the applet. I have tried several solutions from here:

In this forum there was not much advice as to how to remove this problem.
Please help, because I do not want to change the distro or go to Manjaro.
