Ubuntu Networking :: 10.10 - Use Multiple Mobile Broadband Modems - All Attached Modem Is Automatic Go Offline
Oct 28, 2010
I tried to use multiple mobile broadband modems in ubuntu 10.10 and encounter a bug as follows:
When i plug in a new modem, all the attached modem is automatic go offline ( thus my connection is down), and try to redial back, sometime the redial is successful, sometime it's not.
It was working fine in ubuntu 9.10, plug in a new modem, all attached modems stay connected.

I am looking to buy my own unlocked/never-locked mobile broadband modem, and I want it to work well on my 64-bit 10.04 Ubuntu system (triple-booting MacBook 4,1). Is there a list of mobile broadband modems supported in the linux kernel out there somewhere? I did try to find one myself, but no luck. The Huawei E220 looks good, but it is discontinued.

I've been trying to get a USB modem stick to work with Karmic.The modem is the ZTE MF626 HSDPA on a Telstra Next G plan.I've followed all the guides and links on the forums:Have deactivated the CD autorun on the USB stick in XP lsusb is showing "Bus 002 Device 003:ID 19d2:0031 ONDA Communication S.p.A." demsg is showing "usb 2-2: GSM modem (1-port) converter now attached to ttyUSB1"This seems stable as well, ie checking periodically it doesn't seem to be disconnecting By the way,the blue light indicating network communication/modem active lights up after the device has been plugged in for a second or so.
When I go through Network Connections and add a new mobile broadband connection, there is nothing listed in the "Create a connection for this mobile broadband device" drop-down on the first configuration screen - all the guides I've read say that it should be listed here, but none say any debug steps if it doesn't.Some other guides for older versions of Ubuntu and earlier versions of the modem reference a "/usr/share/hal/fdi/information/20thirdparty/20-zte-mf626.fdi"file which I don't have.

How do I installed a sprint novatel 3g modem? I see sprint under the mobile broadband tab when I create a new connection, and it shows all the right information, but I never can connect.

I have a question concerning mobile broadband connections: Is it possible to have multiple mobile broadband connections active at the same time?I currently have two cellphones connected to my Ubuntu box and both of them can successfully setup an Internet connection for my Ubuntu box (say connection X or connection Y), though not at the same time. Unfortunately both connections are very limited in speed (around 10kb/s each. And this is my only access to the Internet where I live). Therefore, I wish to use the two connections simultaneously to download files from the Internet (file 1 with connection X and file 2 with connection Y). Is this method of doubling my bandwidth possible in Ubuntu?

I am trying to switch to mobile broadband, Ubuntu 9.10, Huawei E1750 modem, provider Telia Sweden. So far I tried this:
(previous: tried to get started with an Option Icon 550 modem, but could not do it. Ubuntu froze completely, networkmanager refused to see the modem after this. Read somewhere that it is (next to) impossible with Ubuntu, but Huawei is a better chance. Maybe I changed some settings on the way, went and got a Huawei)
-connected modem, nothing happened
-rebooted to Windows Vista, installed modem
-rebooted to Ubuntu networkmanager sees the modem, when I select it, it gives a message 'GSM network, disconnected'
Also: Ububtu sees the usb stick as a folder

I have a k3806-z vodafone mobile broadband modem, on ubuntu 10.04. I have added the mobile broadband connection with the network manager wizard. But network manager does not list my connection. I installed usb-modeswitch and usb-modeswitch-data. Still nothing. The disc utility tells me it recognises the modem as a cd drive and a storage device. Evidently usb-modeswitch is not working.

I have this usb stick:
The problem is that I have no clue what information I am supposed to give when configuring it through KNetwork manager. The password is disabled and I think the username should be telenor which is my ISP, the other info lines in KNetwork manager, however, I am very uncertain of, and I can't seem to get it working. I have switched from traditional setup with ifup to user controlled through Network Manager and the modem is detected. The module option seems to be loaded and the 'mode' of the stick seems also to be correct, it is not detected as a storage device at least.

I'm using a 'ice.net' D-50 (CDMA EV-DO rev A) mobile broadband USB modem, also sold as Cmotech CNU-680 in other areas. The modem is connected to a USB port on a hp8710w mobile workstation.
As the 11.2 Gnome Network Manager won't connect this modem to Internet (see my first post here), I have downloaded and installed a 'D50 Modem Manager program' from [url]
After unpacking and installing this cmotech-qtmodem-1.6-1.i586.rpm package for suse on 11.2 x86_64, the gui application 'D-50 Modem Manager' is found in the Internet Group.
However, neither this program does connect the D-50 modem really on 11.2 x86_64 (as it did on 11.1 x86_64). Tried both traditional network setup and with Network Manager.
Any idea and suggestion how to trobleshoot this further? I think I've seen that a newer version cmotech-qtmodem 1.9 has been mentioned on the web, but without being able to find and download this version.
Command output as follows:
As normal user:
On the Modem Manager gui: D-50 modem is ready
From Login script Debug window:
As root:
It seemed like the modem connected, but Firefox was not able to connect afterwards (Server not found)

Just loaded Ubuntu 9.10 on a Dell 5100, (XP finally got the bsod) I have verizon mobile broadband, all was very good until I realized I cannot connect wirelessly. The usb modem was not recognized, there is no indication of any wireless connection. There is no icon and nothing happens when the usb modem is plugged in. I have been working on this for hrs & hrs. I am a complete novice on Linux, but CompT1 A certified on PC's

I have an USB (Huawei 1751) modem for mobile broadband. I had it up and running in Ubuntu 9.10 but I had to clear the computer for various reasons. I have decided to only use LTS versions so for the reinstall I have used Ubuntu 8.04 LTS. I have downloaded and installed usb_modeswitch and can see that the modes is changed to the right value. After that I wanted to add a new mobile broadband connection in the network connections wizzard - but cannot see any settings for mobile broadband. I am sure it must be possible - but where is this function hidden in version 8.04 ?

I have just switched to Ubuntu from Win 7 RC. So far its been fun, learning to use terminal and all. But I have got a problem now I cannot find a solution to.
I am using 3 Mobile Broadband. The thing just worked - I plugged it in, created a new connection, modified config a little and was happily browsing.
However, it started acting out yesterday. When I boot the system with the modem plugged in, the USB stick is recignised and NetworkManager starts connecting (I have auto connect on). It then shows the "connected" message, and generally appears working fine.
On the other hand, I cannot open a single page in Firefox, it shows the default server not found page.
I used the approach Windows taught me: close, open, retry. I unmount the 3 Mobile Broadband drive, pull the modem out and reconnect it. NetworkManager then does it's job and this time everything works.
I nether had this problem in Win7 or Vista. It looks to me something goes wrong during the booting when the modem is plugged in.

I decided to give 10.04 a shot, and upon first boot, I was able to setup and use my Rogers Rocket mobile broadband stick. When I rebooted, I found that it was in the network settings, but I was unable to connect, nor did it show up as an option in the drop-menu. I played with the terminal trying to see if anything was wrong, but everything seems normal, which is to say I don't even know what I'm looking for in regards to this type of connection.
I obviously know now that it works, I just don't know what made it stopped for the time being. I'm thinking of doing a fresh install over the current partition, and trying to work the issue from there.

I recently made a clean install of Ubuntu 10.04 and my mobile broadband no longer works. When I plug it in, the set-up wizard does not appear, and even when I run the wizard manually, the modem is not recognised. I know the modem works as when the laptop ran 9.10 it all worked perfectly.
For the record, it is a Huawei E1550 and has 3 Mobile Broadband Pay-as-you-go.

I also have this problem but my internet connection is Mobile Broadband (through a wireless modem HSDPA), not eth0. In this case how can I change the MTU value?

In a separate thread I discuss my issues with getting my Blackberry 9650 tethering with Verizon and Ubuntu 10.10 with bluetooth. I'm still hoping to get that working, but in the mean time, I've actually started to think about perhaps getting a mobile broadband card from a US provider separate from my blackberry anyway - preferably one that works right out of box with Ubuntu.
Does anyone here have any recommendations? I know there's a lot of compatible devices, but maybe someone here can recommend a provider (I don't have to stick with Verizon - willing to go AT&T, T-Mobile, Sprint, etc.) and a USB mobile broadband device that'll work pretty smoothly?

Iam planning to use 3(operator) Mobile broadband in Sweden. I just installed Ubuntu 11.04 in my HP-Pavilion-dv2700-Notebook-PC. Iam not able to configure this mobile broadband(3 operator).
Earlier i was using Telia mobile broadband in Ubuntu 10.04 it was working fine. Now i have moved to operator 3 and also i installed Ubuntu 11.04. I added the profile Network->edit Connections-> Mobile Broadband (tab)i have given all right parameters. Still i didnt manage to connect. I feel like lost connection with the World without the internet.

I am new to Linux. I have recently installed the Ubuntu 11.4 LTS Distro that comes with the Haynes Linux Manual (which I heartily recommend to new users). For the Internet I have a Huawei E1550 dongle on the 3 network in the UK which I'm currently using with Windows XP on my desktop to post this thread. After some initial fumbling, I'm unable to use the dongle with Ubuntu.
