I have an 3.5G USB Modem that I want to share its internet connection in Linux. I tried already, but only got having no internet on my own PC, still without sharing it.
It’s really hard to find some documentation about this and the producer doesn’t give support for Linux 🙁
My modem is from ZTE company, model MF622.
Solution:
It seems that the best way to accomplish what you want is to route the connection to your PC through the linux system. Try this tutorial on the ubuntu community site. If this isn’t what you wanted, comment.
