Fedora Networking :: Mobile Broadband Drops Connection After 30s
May 8, 2010
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.
i am using mobile broadband to connect with network after i connecting mb.it drops it's connection for every 10 minutes.i need to restart to reconnect it.it is happening in kde.
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 using samsung S3310 with aircel when i am connecting new mobile broadband connection my device is not identifying ,so that i cant connect Internet.but everything okay i mean settings in mobile and pc. for same connection i used Nokia mobile its identified and Internet was connected but samsung mobile is not identifying in terminal i typed LSUSB my device is shown in that.
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 am using tata indicom photon+ for mobile broadband internet connection.
Code:
Befor yesterday, I was able to connect via this, but today(i guess a update yesterday is the culprit) i cannot. while it should connect automatically, even usb_modeswitch cannot detect anything.

my /etc/modeprobe.conf is also blank. But I can work with wireless
I have bought reliance netconnect broadband+ 3.1 Mbps connection. I am provided Huawai EC1260 device to make the connection.But using ubuntu 9.1 I am not able to make the connection work. I have tested the device in windows XP and it's working fine there. I don't want to use windows and desperate to establish the connection in Ubuntu 9.1.
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)
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?
does anyone of you use a hauweii e160 usb mobile broadband connection? in ubuntu 9.10 it worked, but now (10.04), after the remove of /proc/bus/usbfs it wont't get recogniced as an internet-device.why should i make a symlink from kernel/debug to /proc/bus/usb/devices
I'm using Mobile Broadband Connection (Huawei 180), When I plugin my RJ45 Ethernet cable, my Broadband connection is no more. I have no access to Internet. why it happens and How can i establish both connections @ once..?
I have discovered that my ISP drops down my mobile broadband connection specially at night. It is a very annoying fact because this type of net access is not cheap at all. I am using Fedora 14 newest core. I am able to configure Network Manager to automatically connect, but... this option does not solve the redialing issue.
Is there any way to set up redialing a dropped mobile broadband connection? A perl or python script, may be?
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'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.
I am trying to use Verizon MIFI mobile broadband and ubuntu jaunty jackalope doesn't detect the connection. Verizon has software for mac and windows but not for linux.
Im able to use nm-applet just fine to setup broadband card. Its a Sprint Sierra 598u. Im running Fedora 10 KDE version. Anyone know how to get it working? i tried the setup process but all it tells me is set up GPS or CDMA so i go CDMA for mine, but then it has some default name, and no providers, as the UBUNTU version did at least...i setup best i can but then after closing configs, i go to nm-applet icon in bottom-right and it doesn't show the mobile broadband connection, also any wireless connections don't work for some reason, but DO show up. just wont connect (which i got every so often when using ubuntu on the machine, was usually a switch off or restart away from fine
I tried to preupgrade to f14 and cancel it after some time. Now, I am facing a problem that I cannot access internet from mobile broadband; but I can access net while i am connected via ethernet or wireless. I have cleared preupgrade files with
Quote: yum clean all; yum remove @preupgrade
$ uname -rs Linux 2.6.34.7-56.fc13.i686.PAE
It can detect my HUawei modem and creating an IP as well. But no Internet. Can you tell me the reason?
This is not really a problem but I'd like to know if anything can be done about it.I run Fedora 12 (kernel 2.6.32.23-170.fc12.i686)/Gnome 2.28.2 on my Acer Aspire One netbook with a 1.6GHz Atom CPU and 1.5Gb RAM.I use a Huawei E160 mobile broadband modem to get online and this works OK; but (for example) I am on Airliners.net and looking at the trip reports, the photos are somewhat 'fuzzy'. Obviously the modem does not download too much data and you just have to do Shift+A to get it to 'reload' the pictures. After this they are crystal clear.However, is there a config setting that you could alter to do this automatically � e.g. download all the image data at once? I have looked in the Network Manager settings for my mobile broadband account and there is nothing in there.
I few days ago I bought a mobile broadband, with dongle model Huawei e1820. I have no problem connecting to the internet. The settings in network manager are correct. But when I use the modem with high traffic for a while, like streaming, the speed gets slower and slower until finally the modem shuts down and restarts itself. After the modem restarts, it connects to the internet again, but now the speed is terrible. And if i continue using high traffic it will restart itself in a matter of minutes. But if I plug it out and don't use it for a while, the speed is back to "acceptable". For a while...
I'm using fedora 15, and have also tried it on Ubuntu Natty with the same result. Reinstalled usb_modeswitch. configured usb_modeswitch with all the guides on the web. No results.
I have a Mobile Broadband connection (as NetworkManager calls it) that works very well until the latest update. Now it fails to connect 99.9% of the time. When it does connect it works very sluggishly.
I didn't update a second computer I have and it still works fine here. Both run F10 x86_64, both are fully updated (except for NM on this one).
Output of grep NetworkManager /var/log/messages | tail -100 from non working machine code...
My connection is much slower on linux than windows (I'm dualbooting so its easy to test). On speedtest.net I get 0.30Mb/s at most on linux but about 2Mb/s on windows.Torrents does not seem to be affected thou. I've got speeds up to about 150kB/s on Fedora.I'm running a fresh install of Fedora 12 64 bit.
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 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.
