Fedora Networking :: Mobile Broadband Fail After NetworkManager Update / What To Do?
Mar 11, 2009
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...
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'
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.
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'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 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.
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 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 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.
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?
In Fedora 14 (kernel 2.6.35.10-74.fc14.i686) I am not able to get an internet connection on my laptop via mobile broadband. However dialing succeeds and the provider starts the daily flate rate accounting.I tried the graphical network management as well as wvdial and even sakis3g (achitecture free variant from URl...).With wvdial (well configured I think) and sakis3g the dial connection is established (permanent blue light on Huawei E169). "netstat -ie" shows that the network configuration has changed (device pp0 instead of eth0 and "netstat -rn" shows that default router is set to 10.64.64.64). But "ping" does not receive data from any internet IP address and browser cannot render any website. A later check call of my prepaid balance said that the daily rate countdown was initiated (so I pay for nothing).
The GUI of the KDE network icon seems to work similar but does not set the usb key into the connected state (only blinking blue light and break-off after a few seconds).Disabling of selinux didn't change anything as well.With Mandriva 2010 I didn't have any problems with same mobile key and provider.
I have a little bit of a prediciment with my Mobile Broadband dongle, even though I know I'm in a 3G area (Dongle Supports 3G connection) my internet still loads at the normal GPRS speeds max of 5kb/s. Is there anyway to change the speed of it or do I have to keep with GPRS at the moment?
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've been trying to make my FC13 Dell d620 work with a Huawei 3G usb modem mode E173. I can not switch the device to modem instead of storage with usb_modswitch. This is what I get on lsusb:
I am having trouble getting NetworkManager to detect my Huawei-Vodafone dongle and I can't figure out why. I went and checked on NetworkManagers website and I should be good to gobut no such luck. look at the following:
manpep@manpep-desktop ~ $ manpep@manpep-desktop ~ $ dmesg | grep -e "modem" -e "tty" [ 0.000000] console [tty0] enabled [ 47.951906] USB Serial support registered for GSM modem (1-port) [ 47.951958] option 3-2:1.0: GSM modem (1-port) converter detected [ 47.952990] usb 3-2: GSM modem (1-port) converter now attached to ttyUSB0
[Code]....
Although "lsusb" see it (as usually) as Huawei model E620, in fact it's a much more recent one. It's the K3520, from last year.
i have both a vodafone and 3 mobile broadband dongles. they both work out of the box, however i am only getting gprs, while i can get 3g/hsdpa using my windows box. is there any gui configuration manager or terminal commands i can use to set it to 3g/hsdpa only? im running ubuntu 9.10.
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 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 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.
Code: sudo ifconfig eth0 mtu 1492 ifconfig | grep MTU
And then try surfing...
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.
