My laptop has a dual booting option and so far I have been using Fedora20 along with Windows7. Few days back I have fresh installed Fedora23 in place of Fedora 20. But from that day I can not been able to connect internet with my micromax 3g usb dongle, although in Windows7 it still connects internet. In Fedora20 also it was working fine. What is happening is that the modem is detected , but configuring it by NetworkManager, when I try to connect it to internet it fails to connect. I can connect to internet through other wifi connections. I am noting down the outputs of some of the commands I have executed.

Result of "dmesg"(only relevant portion):

Hello

Is ModemManager running? What happens when you do sudo systemctl start ModemManager ? If that works you need to enable it sudo systemctl enable ModemManager

Kind regards

Yes. I have run both the commands. Still it is not connecting.

Please post the output from dmesg after it fails to connect.

Are you using fedora 23 gnome version? I also got the same problem when I installed the gnome version. I was also not able to connect to internet through my dongle. Now I have installed KDE version and its truly working. My suggestion is try KDE package and then see what happens. I think there is a bug in the gnome package of fedora 23, if this helpful then mark it a right answer so that some other people will get right answer for this problem.

I use my USB 3G dongle in Fedora 23 with GNOME to connect to the internet and it works fine. Yours could be an isolated issue.

First of all, this is not a bug related to gnome package. This is the kernel bug.

I have installed Ubuntu 16.04 and Fedora 24 both these systems have same issue. The kernels from both operating system are unable to detect the USB Dongle as Modem instead it is detected as USB Mass storage or CD storage.

I also have Ubuntu 14.04.3 LTS installed on other system in which Dongle is getting detected properly.

One workaround can be upgrading the kernel version or downgrading it.
