FWIW, I have never had any problems using PPP with my Huawei E392 modem on LTE, except for upstream bandwidth being limited around 8 Mbits/s. But that is a somewhat different firmware with a different set of bugs from the E398
The issue sounds like a firmware problem. Which isn't unexpected. The PPP firmware support is probably completely untested, as the Windows drivers don't use it. If you are lucky then it works. If not, then there isn't much you can do about it. The only sensible workaround is using the newer ModemManager with QMI support. But I'm biased of course :-) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1042456 Title: Huawei e398 doesn't work Status in “gvfs” package in Ubuntu: Invalid Status in “modemmanager” package in Ubuntu: Incomplete Bug description: After configuring in Network Manager all parameters specific to my ISP I can't connect to the network with such results: Aug 28 00:01:07 ubuntu NetworkManager[1152]: <info> Activation (ttyUSB0) starting connection 'Cyfrowy Polsat Default' Aug 28 00:01:07 ubuntu NetworkManager[1152]: <info> (ttyUSB0): device state change: disconnected -> prepare (reason 'none') [30 40 0] Aug 28 00:01:07 ubuntu NetworkManager[1152]: <info> Activation (ttyUSB0) Stage 1 of 5 (Device Prepare) scheduled...
