Description Yosayan 2016-07-09 22:39:17 UTC 
Hi and welcome,
At the beginning, sorry for my english but I believe, that I would be understood ;)

Basic info:
-I have a mobile modem: SIERRA WIRELESS AIRCARD AC318U ( idVendor=1199, idProduct=68a3 ).
-Connection to the Internet only through the mobile modem AC318U.
-All tested Linux are 64 Bit version: LIVE DVD and also Live USB pendrive (persistent Linux: Mint and Xubuntu).
-I am newbie ... sometimes advanced but generally newbie ;)

My first linux in 2014/2015 was Linux MINT version 13 "Maya" LTS (based on Ubuntu 12.04 LTS).
When I was using Linux MINT v.13 I had no problems connecting to the Internet (through menu NetworkManager: Mobile Broadband/ModemManager).
It was always fast and efficient, stable as rock and generally OK. It worked fine.
But when I started using Linux MINT ver. 17 "Qiana" (based on Ubuntu 14.04 LTS) there were problems with the internet:
- system started up (modem phisicaly unpluged)
- linux loaded (graphical interface "Cinamon" loaded)
- in Network Manager menu no Mobile Broadband
- now, modem phisicaly plugged into the USB port
FIRST CYCLE
- modem detected, Mobile Broadband option is visible in Network Manager menu bar
- initiate connection, connection established, shows message: "Mobile broadband network. You are now registered to a roaming network"
- after 2-3 second next message "Disconnected - you are now offline" (Mobile Broadband not visible in Network Manager menu)
SECOND CYCLE
- modem detected, Mobile Broadband option is visible in Network Manager menu bar
- initiate connection, connection established, shows message: "Mobile broadband network. You are now registered to a roaming network"
- after 2-3 second next message "Disconnected - you are now offline" (Mobile Broadband not visible in Network Manager menu)
http://pokazywarka.pl/modemmanager_messages/

This cycle is repeated 4-5(or 6) times, even when reinsert (unplugged and plugged) the modem to the USB port.
Modem connects and disconnects...Mobile Broadband menu appears and disappears...
The situation repeated itself when the system started with a modem inserted into the USB port.

Interesting fact: When I used the modem with the 8GB card (inserted to the microSD slot), it also rhythmically appear and disappear (as a volume pendrive, disk, on linux Cinnamon desktop).

In search of a solution I checked many versions of Linux.
At the time, I did not know that the problem is in the new version of the modem manager.
The last FUNCTIONING (without any problems) MODEM MANAGER version was numbered 0.5.2.0
All new versions of Modem Manager (tested: 1.0.0 , 1.4.0 , 1.4.12) numbering OVER 0.5.2.0 effectively prevented connection to the Internet !

TESTED VERSIONS OF LINUX:
**************************
no problem=>Linux MINT 13 Maya (MM=0.5.2.0)
problem=>Linux Mint-17 Qiana , 17.1 Rebecca , 17.2 Rafella , 17.3 Rosa 

no problem=>Xubuntu 12.04 (MM=0.5.2.0)
problem=>Xubuntu 14.04 , 15.04 , 16.04

no problem=>LPS-1.5.4 and LPS-1.5.7 (MM=0.5.2.0)
problem=>LPS-1.6.4 (problem)

no problem=>Fedora 17 (MM=0.5.2.0) and (interesting) FEDORA 18 with ModemManager ver. 0.6.0.0-2.fc18  (kernel: 3.6.10-4.fc18.x86_64)
problem=>Fedora 19 , 21 , 21.5

no problem=>Debian 7.0 , 7.11 Wheezy (MM=0.5.2.0)
problem=>Debian 8.0 , 8.1 , 8.4 , 8.5 Jessie

The same problem, with the connection to the internet, I had also in those linux:
OpenSuSE 13.2
MANJARO 15.2 , 16.06
Tails 2.0 , 2.3
Mandriva

But, ALL TESTED VERSION (no problem/problem) PROPERLY RECOGNIZE (in the same way) MY MODEM SIERRA WIRELESS AIRCARD AC318U !!!
(LSUSB): ID 1199:68a3 Sierra Wireless, Inc. MC8700 Modem
(DMESG): usb 1-4: New USB device found, idVendor=1199, idProduct=68a3
(DMESG): Product: AC318U
(DMESG): Manufacturer: Sierra Wireless, Incorporated

And at the time I suspected that the problem is in the Network Manager, but I was wrong.
I searched the internet but don't found how to solve the problem :(
I capitulated and I stopped using the Network Manager + Modem Manager).
I started using Wvdial (also tried Minicom or PuTTy).
Wvdial worked (and still works) stable as a rock, quickly and without problems in ALL versons of Linux.
However, the problem pestering me....
In the meantime, I was looking for a solution, because e.g. the other linux that interested me  [ LPS (https://www.spi.dod.mil) ] is a closed system, without root privileges and the possibility of installing additional software, for example wvdial, so it is useless :(

FINDING ERROR and (nearly) SOLUTION (but limited)
**********************************************
Recently, I came across this post "user 116024" (problem and reply-solution):

"Sierra Wireless 313u 3G broadband modem will not work since upgrade to 14.04"
http://askubuntu.com/questions/491841/sierra-wireless-313u-3g-broadband-modem-will-not-work-since-upgrade-to-14-04
or short link
http://tinyurl.com/zvojku5

My reaction: "It is my problem, and even a modem of the same company!"
I'm currently working with Linux MINT 17.3 Rosa (based on Ubuntu 14.04.3) and I did what "user 116024" recommends.
I replaced the original Modem Manager version 1.0.0 to old ver. 0.5.2.0
http://packages.ubuntu.com/precise/net/modemmanager

[My comparison between the two versions of MINT 17.3 (MM 0.5.2.0 and MM 1.0.0) as an attachment "MINT_17.3_ MM_comparison"

BINGO !
It works perfectly (also in Xubuntu 14.04).
Came back the functionality of a modem through Network Manager (Modem Manager) !
ATTENTION ! was replaced ONLY ONE package, ONLY ONE file, Modem Manager and everything is back to normal !

But it does NOT WORK in Xubuntu 16.04 , Debian 8.4 , Debian 8.5 , no Mobile Broadband option in network menu bar (it shows for one second and disappear).
After deleting the Modem Manager v1.4.12 or v1.4.0 and run Gdebi, has removed one more file and has installed nine files but finally Gdebi says:
..............
Setting up modemmanager (0.5.2.0-0ubuntu2) ...
Job for modemmanager.service failed.
Errors were encountered while processing: modemmanager
.............
I think, the problem grows.... new versions of MM, new libraries, new relationships between them, more files to delete-replace ....
The normal functioning and use of the Sierra 318U broadband modem was NOT RESTORED (Xubuntu 16.04 , Debian 8.4 and 8.5).

As attachments logs (lsusb, dmesg, sysog etc.) from linux: Xubuntu 14.04, Xubuntu 12.04 (it works OK, I add it logs for comparison), Xubuntu 16.04 and Debian 8.5
(Xubuntu 14.04 and 16.04 generated ERROR RAPORT, I attach it as screenshots).
Also DEBUG lLOGS from Xubuntu 14.04 , 16.04 and Debian 8.5
I think it will be very helpful in solving this problem, to fix it.

I think that many people (Sierra modems users like me) have such a problem but they decided to use: Wvdial, Sakis3G,  PuTTY or Minicom.
But I am waiting and I believe You find a solution to the problem
I wish you success in that.
Regards

Yosayan

PS.1.
I tried to install the latest MM ver.1.5.992 but there were problems when compiling it (Live DVD linux and loss of data after a reboot).
I will try... but I think, the error repeats.

PS.2.
I want to buy a different type of Sierra modem (4G/LT model), but I'm afraid that described problem, applies to all of Sierra/Netgear models :(
http://kb.netgear.com/app/answers/detail/a_id/22869  (list on the right)

I take into account the following Netgear/Sierra Wireless Aircard modems:
=>AC 320U LTE
vendor=0f3d (0x0f3d)
product=68aa (0x68aa)

=>AC 340U LTE
vendor=1199 (0x1199)
product=9051 (0x9051)

=>AC 330U LTE
vendor=1199 (0x1199)
product=68a3 (0x68a3)

>>>>>>>>>>>DEBIAN 8.5 Live DVD<<<<<<<<<<

System:	Debian GNU/Linux 8.5 (jessie)
Kernel: 3.16.0-4-amd64
NetworkManager - version 0.9.10.0-7
ModemManager - version 1.4.0-1
http://pokazywarka.pl/b1hm9p/

SHORT DESCRIPTION: No permanent connection to the internet. Modem after the conect (or rather after trying to connect), hangs up after a few seconds, then again connect for a few seconds and again disconnects... (modem LEDs blinking...searching for service, initializing....modem has detected a 3G network and is ready to connect....disconnect) ... all about 6-7 cycles.
In this test, modem was also removed and re-inserted into the USB....cycles repeated :(
Mobile Broadband option shows in Network Manager menu bar only for max one second and disappear.
Look below: lsusb, dmesg, syslog

Comment 8 Yosayan 2016-07-09 22:57:12 UTC 
Two additional tests. I think they will be very helpful (especially the contents of the file SYSLOG) in solving the problem.

1. Linux MINT 17.3 on persistent PENDRIVE (based on Ubuntu 14.04) with OLD version of Modem Manager 0.5.2.0-0ubuntu2 (installed it after deleting ver. 1.0.0-2-ubuntu1.1) => no problem to connect to internet, works perfect

DEBIAN 8.5 (MM_v1.5.993) Live DVD lsusb, dmesg, syslog

I found a new version MM package for the Debian 8.5 and it is ready-to-install in the "deb" format.
https://packages.debian.org/en/sid/modemmanager
I removed the old version MM_1.4.0-1 and installed (by Synaptic) the new: MM 1.5.993 and libraries:
................
libmbim-proxy (1.14.0-1) over (1.10.0-2.1) ...
libmbim-glib4:amd64 (1.14.0-1) over (1.10.0-2.1) ...

libqmi-glib5:amd64 (1.16.0-1) ...
modemmanager_1.5.993-1_amd64.deb ...
.................
Unfortunately, nothing has changed, all of the symptoms described previously, still exist, there is no internet connection :(

I don't see any connection attempt in this last log files you sent. Could you retry to do a connection attempt in this setup?

Anyway, what I see in other logs is that the modem is actually rebooting itself at some point, which looks like a firmware error:

If this is really a firmware error, we could try to avoid the specific sequence that is triggering the issue, by disabling one by one the new commands we send in MM 1.x (which doesn't work) w.r.t. the commands we send in MM 0.6.x (which does work) until we get a successful connection.

Anyway, does this device have the latest firmware available installed? I would suggest to look for the latest one and install it.

Done:

DEBUG LOGS_no-2 MM (v.1.5.993) & NM - Debian 8.5 Live DVD 
It includes two tests, the second after removing and re-inserting the modem

SYSLOG - Debian 8.5 Live DVD (MM v.1.5.993)
It includes the contents of syslog, after leaving debug mode (normal use)

For better comparison, I made additional listings of SYSLOG files:
SYSLOG - Xubuntu 14.04 (MM-1.0.0)
SYSLOG - Xubuntu 16.04 (MM-1.4.12)
SYSLOG - Debian 8.5 (MM-1.4.0)

I'm sorry but this is a MISTAKE!.
I checked again version of Fedora 18 (MM 0.6.x) and the internet does NOT WORK!.
I had to go wrong with Fedora 17 (MM 0.5.2) and its operation I assigned to Fedora 18.
The last good version is MM 0.5.2.0 !

My modem is from 2011 (bought in 2014).
Immediately after the purchase I was looking for a new firmware and software, but did not find.
I think it was never firmware update for AC318U, because now on the Netgear website, there is an old firmware for the very old AC307U.
I remember the Sierra Wireless information, to discontinue support AC318U (no new software, firmware, etc.)
Then it was that info, AirCard Mobile Broadband Devices are now sold and supported by Netgear.
Yesterday I found the new version of software to support AC318 for Windows 10 (from August 2015):
"AirCard Watcher B4096 (Windows10)" but no firmware update.
http://downloadcenter.netgear.com/en/product/AirCard%20318U%20(O2)#searchResults
It's strange, because Netgear did the firmware update (May 2015) for a newer model AC320U.
http://downloadcenter.netgear.com/en/product/AirCard%20320U%20(Telstra)#searchResults
It was as if Netgear decided that for Windows 10 the new firmware will not be needed ?

DEBUG LOGS_MM-1.6.0 & NM + SYSLOG - Debian 8.5 Live DVD

MM-1.6.0 was released so I did three listings:

1. DEBUG log MM-1.6.0
2. DEBUG log NM-0.9.10.0
3. SYSLOG (after completely exit the "debug mode" and return to normal use)

but  AC318U still doesn't work (reboots 6-7 times)
Comment 23 Yosayan 2016-08-12 18:40:28 UTC 
In my first post I wrote:

> no problem=>Fedora 17 (MM=0.5.2.0) and (interesting) FEDORA 18 with ModemManager ver. 0.6.0.0-2.fc18  (kernel: 3.6.10-4.fc18.x86_64)

And this is true but for Fedora 18 Xfce Live DVD (Fedora-18-x86_64-Live-XFCE.iso)
But in one of the next posts I wrote something else:

> I'm sorry but this is a MISTAKE!. I checked again version of Fedora 18 (MM 0.6.x) and the internet does NOT WORK!.

And it is also true, but in this case I checked the Fedora 18 KDE Live DVD (Fedora-17-i686-Live-KDE.iso)
I forgot that I downloaded two versions of Fedora: XFCE, and KDE interfaces.
In the version of the KDE interface modem logs on to the network and connects to the Internet but Firefox can not load any pages.
As if Firefox does not see the connection (and the same is in the Fedora 17 KDE (MM = 0.5.2.0), and there is no problem in F17-XFCE)

I think that the problem is certainly not in MM but in the KDE version of Fedora.
Fedora little messed, because XFCE versions works perfectly.
Yesterday I checked again. Without any problem working all of the following versions:
Fedora 17 XFCE: MM 0.5.2.0
Fedora 18 XFCE: MM 0.6.0.0-2.fc18 , NM 0.9.7.0-12.git20121004.fc18
Fedora 19 DESKTOP: MM 0.6.2.0-1.fc19 , NM 0.9.8.2-2.fc19

Because of the good working F19, I changed the title of bug 96874 (from MM 0.5.2.0 to MM 0.6.2.0):
"AC318U doesn't work (reboots itself) since MM 0.6.2.0"
