Ubuntu Networking :: Mobile Broadband Connection Tcp Not Always Working?
Jan 12, 2010
I have a strange problem with my mobile broadband connection. I hope I am not the only one (so it will be fixed), but since I haven't found any others having the same problem yet, I am not so confident.I started using mobile broadband, via a HUAWEI E1762 HSPA USB stick since Jaunty. I've had the same problem in jaunty as I do now in Karmic. Although in Karmic, i've had additional problems (that problem i've found listed as a known bug).The problem is that when I get my mobile broadband to connect, it is sometimes, somehow, not fully connected. Symptoms are as follows:
1. panel icon shows connected and good strength (good)
2. skype connects, and I can chat and voip (good)
3. ping does not work (bad)

i recently installed ubuntu 10.04 in my laptop. everything is working fine except for my mobile broadband connection. i use a huawei ec1260 USB 3g modem to connect to the net. the OS detects the modem fine and the network manger applet prompts me to set up the connection as well i.e entering the username, password, number to be dialled etc. however when i actually try to dial the connection the applet icon flashes for a long while and a notification pops up saying connection disconnected. has anyone come across same kind of problem and solutions, if any.
Earlier i used the same modem in in karmic i was able to connect to net and even now i am able to connect using the modem in windows 7 as well

i downloaded ubuntu 10.10 for learning purpose. All goes well, i installed it successfully. The problem which i face is that when i connected my mobile broadband device, ubuntu detects it and i have succesfully made the connection. But the network Manager is showing "disable" Mobile Broadband connection. I tried to put a check on Enable Mobile Broadband but can't check it. So i can't access Internet in ubuntu. I think some offline package installation should be there to resolve the problem, or some console commands. I tried to use the (wvdial) which i use at Backtrack. but i think ubuntu did not have.

I use Nokia N900 under T-Mobile as a broadband modem. It is connected via USB. There was no connection problems under 10.04 or 10.10. Now I have installed Ubuntu 11.04, and I cannot connect any more.
Here are the log messages that I get when trying to connect:
Code:
May 30 14:32:06 ubuntu-sager NetworkManager[759]: <info> Activation (ttyACM0) starting connection 'T-Mobile Internet'
May 30 14:32:06 ubuntu-sager NetworkManager[759]: <info> (ttyACM0): device state change: 3 -> 4 (reason 0)
[Code]....

I just installed Ubuntu a few days ago and am loving it so far. There is, however, one huge problem which is spoiling all my fun: I can't access my gmail.
I'm using a Huawei E220 USB modem with T-Mobile UK. Plugged it in and was very impressed when I could set up my connection with minimal fuss. When I try to load gmail though, I get stuck with the statusbar saying 'Waiting for www.google.com...'. All other sites work fine (including google.com), and I don't get this problem when connecting though the Web 'n' Walk software in Windows XP. Has anyone got any ideas on how I can start working this out?

I'm having problems with my mobile connection. This has been working fine for months, but in the past few days it has connected OK, I've been able to transfer data, but after 30s the connection closes. Setup is Acer AA1 with F12 connecting via bluetooth to Nokia 3110c on O2.
So to try and figure out what's happening I put the bluetooth dongle in my desktop PC, also running F12, made a connection and again it dropped out after 30s. Then I fired up windows on the AA1 and made a connection using the same dongle, this time it held up OK. This leads me to think that something has changed recently in F12 to upset it.

In the last week I have noticed that sometimes my Mobile Broadband connection just goes off without me doing anything! I have credit on the dongle account, so it isn't that. I'm using fedora 14 on an acer aspire one netbook. Dongle is a Huawei E160 on o2 here in the UK Kernel is 2.6.35.11-83.i686.fc14
Sometimes unplugging and replugging the usb dongle works. Othertimes, I have to leave it out for several hours. It does seem to happen daily, though.

I am having problems with my 3 dongle- when I connect it to my netbook it flashes green so it detects a 3G network. However there is nothing in network manager enabling me to choose the mobile broadband so I can't use it. I know there should be an entry "mobile broadband" after the wireless networks listed.
I know the dongle works because I have previously used it successfully- I was using Linux Mint 8 and have now updated to version 9 and when I have tried to use it have been unable to do so.
I have gone into the connections and my 3 connection is present but there is no way for me to select it in network manager.

I just installed Fedora 11 (excellent work by the Fedora team!) and got my Verizon mobile USB CDMA device working after some file modifications (easily found via searching).
I have to click the network icon in the task bar, and select "Auto Mobile Broadband (CDMA) Connection" to get it to connect though. It then shows up via "ifconfig" as ppp0 and all is good.
But how do I get this to auto-start when the system reboots? It doesn't show up in the network manager, and I'm not even sure how to use command-line to start up the CDMA connection! I only can do it via clicking that icon.

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.

I have successfully configured my Mobile Broadband (USB 3G/HSDPA modem) via NetworkManager.Both SmartBro & Globe Tattoo, (these are both providers in the Philippines) connect successfully to their respective networks but my observation is the connection is slow if we are to benchmark these connections running on M$ Windows.
Is there any tweak available to enable the connection speed to improve? I know that there are other factors that affect the connection such as the signal and PC speed. I am currently using a brand new Intel Atom netbook.

When using a Verizon UM150 aircard, it is quickly recognized in Ubuntu 10.04. It installs and connects quickly and seamlessly. After anywhere from a few seconds to a few minutes it disconnects and then disappears from the network manager. To reconnect I have to exit and reboot into Ubuntu. I suspect that there is a conflicting driver that needs to be blacklisted.

I'm setting up a computer with xUbuntu installed and wan't to run it as a PPtP VPN server.
I'm using a mobile broadband for internet connection, with DynDNS wich updates the host with public IP-address.
I've managed to set up the connections and installed the needed packages. The problem appears when I connect to the VPN server through another computer;
When I get connected to the VPN server the remote computer recieves an IP-address from the server (xUbuntu) wich is great! But the server changes prefered network, from the mobile broadband to the wired network wich results in the remote computer losing it's connection to the server.

My friend switch to Ubuntu (he has a 9.10) and want to set up the mobile broadband. He has a usb modem stick Hyundai mb-810. We tried everything - from the usb-modeswitch to wvdial and nothing works. We have read millions of pages of tutorials and forums but still - nothing works. He is now thinking to go to Windoze XP and leaving the Linux community though he is impressed with the Ubuntu.

I'm running Ubuntu 10.04 on my netbook and I am trying to get my Orange ZTE MF636 3G+ mobile broadband working.
Actually, about two times it worked and was connected and I was using it. Though that appears to have been a random and non-recratable event.
Code:
I tried usb_switchmode but that tells me:
Looking for target devices ...
Found devices in target mode or class (1)
Looking for default devices ...
[Code]....
I do notice that sometimes the device is mounted as a CD. I've tried ejecting it and it appears to be recognized (i.e the above messages appear in dmesg).

I am running Ubuntu 10.10 on Hp Mini 110. I can't get Mobile Broadband to work ... whenever I plug a USB device in, nothing is detected and there is no option to connect to mobile broadband. The devices I have tested are;
1. ZTE MF636
2. ZTE MF626
3. Huawei K3565-Z
4. Nokia 5800XM phone in PC Suite Mode (works on my other laptop running Ubuntu 10.04)
I have tried uninstalling with a full purge of USB-Modeswitch and then reinstalling it. This machine is upgraded from 10.04. It wasn't working in 10.04 either.

I just installed 10.10 on a my new Aspire One Acer netbook and I got a mobile broadband USB stick from Wind mobile.
The stick is activated because it works on my 20 GB Windoze 7 O.S. but it doesn't work at all on my 140 GB Ubuntu O.S. Both systems are on the same machine so I know it's not a hardware problem either.
Here's what happens: I log on to Ubuntu, plug in the stick and I select the "New mobile broadband GSM connection" in the network connections menu.
From there I selected my country (Canada) and my mobile provider (Wind Mobile) than I selected my plan (Mobile Broadband) and my APN (broadband.windmobile.ca).
Then the stick blinks slowly and the network icon looks forever for a connection but no matter how long I wait no connection ever establishes. My roomate has it working on his HP laptop Ubuntu but no luck on mine. The stick just keeps blinking, a steady light indicates a connection.

I have an acer 532h aspire one, running ubuntu 10.04.
Basically, I bought a Telstra Turbo USB broadband stick and I've been having a bit of hell getting it to work. First I couldn't get the computer to recognize it had been plugged in at all. I downloaded the modeswitch packages to no avail. I tried a few other terminal tweaks but they didn't change anything either. I left the card in and restarted the netbook and it finally recognized the wireless card. I was able to surf the internet for an hour or so a couple times. But after stowing the computer away for a couple hours and turning it on again, I found that this work around was no longer effective. So now I'm back to the blue light never blinking and I have to tether my phone and pay ridiculous data charges because I'm in the middle of nowhere.
I'm really new at troubleshooting things that don't work right out of the box.
It's a telstra turbo prepaid wireless broadband. The stick isn't even recognized as removable media.

I need Internet on the road so brought a netbook and a USB Mobile Broadband stick. I've followed the installation instructions provided by the provider but this still does not work. I've also tried a couple of similar installation instructions found around the net. Has anybody had any luck getting this to work in Fedora 14? How did you or how can I get this to work?

I have just upgraded to Ubuntu 9.1 and now my mobile broadband connection will not work. The dongle says it is connected to my provider but Firefox is telling me it cannot find the web page. Everything was working perfectly before the upgrade!
Error message: The browser could not find the host server for the provided address.
