Periodic breaks in communication (modem ZTE MF 667)

[Tamir]

If you create access to the Internet using usb modem ZTE MF667 then the network periodically breaks.
After connecting the modem ZTE MF 667 works extremely unstable. If when loading using a torrent client then the network is stable, if you just look for information on the Internet, that is not stable (that disconnection occur very
often).

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Artem (artem-terehin)]

Confirm, without installing software from zero cd network-manager doesn't see the device Huawei E3531

[danelli (danil-red)]

Confirm the behavior of Network Manager in respect of Huawei E3531.

[Lavine (diliwune)]

Confirm - the operating system does not see the modem because tethering Huawei E3531 cd-flash. Specifically usb-modeswitch not automatically switches the device to the modem mode.

[Purihan (piruhanise)]

Confirm the problem is that the device does not automatically switches to the modem (no udev rules for this modem are in / etc / udev / rules.d.)
