OpenSUSE Network :: 11.2 - 3G USB Broadband Modem Keeps Disconnecting
Jan 23, 2010
I am running a 3-G wireless USB broadband modem, and connecting with Network Manager, but I keep getting disconnected when idle after 5-6 minutes. I am used to using Kinternet to connect with my 3-G wireless USB broadband modem, and setting it up in Yast / Network / Modems, but was not able to configure my modem there (for some mysterious reason) so ended up using Network Manager instead.
What's going on here regarding YAST being unable to configure my modem (even when Network Manger is disabled). But my main problem at this point is that my connection times out after about 6 minutes if I'm idle. This is a big problem for me because I type slow and frequently get disconnected while posting on message boards. Where are the idle time out settings are for Network Manager? I can't seem to find them.

I recently got one of these modems and it had discovered very serious detection problems. I had been using one of the Cricket PCMCIA modems but it had a problem of dropping connections every 30 seconds or so. Anyway, this modem works a lot better but there is a trick to get it working.
Since the modem has a built-in flash card reader and flash memory containing the Windows software, when you first plug the device in, it is detected by the OS as a flash drive rather than a modem. If you try to configure the modem at this point, it will be impossible since no modem will have yet been detected.
In order to get the device to be detected as a modem, it needs to be "flipped". The following thread from the Ubuntu forums discusses the details of the problem and contains a link to a utility to "flip" the device: [ubuntu] HOWTO: Cricket Wireless A600 Broadband Modem - Ubuntu Forums
Once the device is flipped, I configured it using YAST / Network Devices / Modems. Mine is detected as /dev/tty/ACM0. I use Kinternet to connect, though Network Manager may also work, but I have not yet tested it.

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 have a broadband mobile modem iCon 225 (Option) with SiMobil provider (Slovenia). I run ubuntu 9.10 (Karmic Koala). I connect to the internet without problem. After a few minutes, the modem lights start signaling that there is no connection, but the network manager shows connected status. I have to reconnect the network manager to regain connection. After about a dozen times of reconnecting like this, I have to reboot the system, as it won't connect, even if I unplug and replug the modem.
I've noticed these frequent disconnects have started a few days ago. I did experience disconnects in the past, but as nearly often as this. I can't attribute disconnects to activity/inactivity, as they seem to happen no matter what I do.

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'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)

I connect to the internet with a mobile broadband dongle. I would like to change the dns settings as page loading seems to be running slow. However, there is no ip tab associated with mobile broadband in the knetwork manager module. There is however for my vpn connection. I have found reference to the ip tab in other postings but alas I am stumped. Is it possible that the mobile broadband connection does not load that tab whereas users on wireless or ethernet have it? That is the only solution I can think of.

Problems with setting up mobile broadband in KDE4? Than use this instruction: openSUSE starter: Step 2. Need mobile broadband? Use the GNOME applet to make the GNOME nm-applet work under KDE. With this nm-applet I have set up mobile broadband within couple of seconds.

I have a Huawei E173u-2 mobile broadband usb stick. It is recognised as a gsm-modem and shows up as such in the networkManager-plasmoid. I have set up the connection details for my ISP (O2), but I can't connect. When I click on the connection, "signal strength" is shown as well as "operator" (o2 - de). The "connection state" changes to "Preparing to connect", then "Setting network address". Then the modem vanishes and comes up again a few seconds later.
Here is the log (/var/log/messages):
Code:
It seems like there is a connection for about 5 seconds, then the modem hangs up and restarts .
The stick works fine with our windows netbook, so I don't think it is a hardware failure.
How do I get this working?
My system:
opensuse 11.4
kernel 2.6.39-30-desktop (2.6.38 gives the same error)
kde 4.6.3
plasmoid-networkmanagement 0.9.svn1192577-168.6

I tried ubuntu and am very happy with the smooth running and clean interface. I am having trouble setting up my network connections. It seems that I am unable to connect to the internet via my broadband modem if I am connected to my LAN via wifi. I think I need to seperate the networks so that the internet traffic does look on the lan for [URL]. I don't think I have had this problem when I used much smaller distros where I had to set it up by hand.
I might need to add some details I am just not sure what is relevant. I only have a basic understanding of what is going on.
solution:
Solved in #ubuntu irc chan with help by erUSUL.
Just in case anyone else is searching for the same thing.
In network connections in the ipv4 settings tab I edited routes by clicking the button and checked the box next to: "use this connection only for resources on its network"

I manage to get my mobile broadband working (connected, I mean) in both root & user account. However, my web browser, IM etc only work in root account.In user, knetworkmanager does show that my Huawei E160G is working fine, connected but I still can't surf the net & chat. I've included the dialout & uucp group for user account but that still doesn't resolve the problem

How do I get information about the SIM card of my USB broadband modem, for example it's phone number, serial number and so on, in Ubuntu 10.04?Not about the usb modem itself - just the SIM card inside it.Is there a way to probe it from the terminal, like you probe for usb devices with lsusb?

Anyone has difficulty in configuring the USB modem Huwaei 1260. I'm using photon plus broadband connection. Here's how I configured it.
Here the vendor id is 12d1 and the product id is 140b.
Now you have to do a modprobe.
Run wvdialconf as below.
Scanning your serial ports for a modem.
Found a modem on /dev/ttyUSB0.
The modem configuration will be written in /etc/wvdial.conf as below.
Make changes as below to the /etc/wvdial.conf
Run wvdial
Wow You are on to the net.
If your browser gives problems loading the pages add the nameservers in /etc/resolv.conf as below.
Then run the browser, there should not be any problems.

I've been trying to use the onboard modem on my laptop for Internet connectivity. From what I can gather, Ubuntu hasn't installed a driver for the modem.
When I connect my phone using a usb cable to the laptop, I'm able to connect and browse. However, the network manager doesn't seem to have a driver for the onboard modem because it doesn't recognize it.

I have bought a new USB modem from my service provider. The model they provided is "Huawei EC1260" Huawei Terminal. As usual the official support is for windows and mac.
I tried to install this device using two methods..
1) Set knetworkmanager settings to "traditional with ifup". Then in wireless setup there is a choice of having "usb" (A tick box). I selected that, and setup completed successfully but the knetworkmanager was not up(I did ifdown wlan0 (wlan0 was the wireless config name), ifup wlan0 and the rcnetwork restart.)
2) Again knetworkmanager was set to "traditional method with ifup. This times while adding the connection I specifically selected the type "USB", then clicked to finish the configuration. The configuration finished without any errors but when I checked the Network Configuration screen no USB device was added there.
Are there any specific steps to configure a USB modem
