Using my usb mobile broadband dongle I am able to access the internet about 25% of the time. I am able to make a connection to the '3' wireless network 100% of the time, but often Mozilla and all other applications that rely on an internet connection do not recognise that this connection has been successfully established, and give me error messages claiming there is no internet connection.
I can't discern any pattern as to whether the connection will be recognised or not. When it isn't recognised, the only solution is to disconnect and reconnect to the network. Sometimes this works and sometimes it doesn't. Sometimes restarting the computer fixes the problem, and sometimes it doesn't. I also have access to a wireless network at uni. I have no problems using this network whatsoever. Housemates using the same dongle on Windows have no problems. I'm using an Acer Aspire one, the dongle is a Huawei e220, I'm running Ubuntu 9.10. I have only recently reinstalled the operating system and have not needed to mess around with any network settings to get the usb dongle to 'work' the way it is currently.
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 deployed to Iraq and the Earthlink ISP here uses PPPoE to configure a connection to their wireless broadband. His english skills are pretty good and from what I gather, he's got a DSL connection that he's trying to connect me to. He showed me how he does it on a Windows machine but I can't figure it out on my ubuntu laptop. That windows machine didn't need any IP addresses or server names. It only used a username and password to connect. Of course a strong wireless signal detected was also pre-requisite.
I know my laptop works because I've had great success with it here lately, just not on the Earthlink service.I see their wireless is broadcast and I can connect to it. I just can't figure out how to post my credentials and authenticate.I don't see a way of entering my username and password because I don't know how to install (or configure) for PPPoE.I did use the pppoeconfig and got to the part where I add my username and password, but most of what's going on up to and after that, I do not have the knowledge base to use. So I figured that allowing the defaults and recommended settings would be acceptableYou'll have to forgive me if I've asked another dumb question here. I'm another one of those Linux enthusiasts who is learning and I'm just not willing to switch back to MS just to get internet while deployed.
I've got UNE 10.10 installed on a Samsung N150 that uses the RTL8192E for wireless. When the wireless works then it generally works okay, but I'm having problems with reboots and long-running connections. This is different to the mass of posts (mainly from 2009) about the card not working at all, so I started a new thread.Basically, 90%+ of cold boots result in a successful wireless connection, with Network Manager remembering my WPA password.
When the wireless is up then it never obviously drops out, but I've got an app with a long-running connection that seems to disconnect itself occasionally. Looking at Wireshark then it appears that there are a number of retransmits, and a big batch just before it disconnects (which implies that the app is dropping its connection because it thinks the other end disappeared). Running the app on another machine with a different card but through the same release of Ubuntu and the app and the same router doesn't result in retries or drop-outs.On the times when a cold boot doesn't successfully reconnect then it asks for the WPA password, then continues trying, then asks for the WPA password again, then continues trying, then asks...and so on until I rmmod and modprobe the driver.
I originally had problems with the machine refusing to restore after a hibernate/suspend, but this was solved by a tip to rmmod the driver on hibernate/suspend and modprobe it on restore.The wireless will now work okay on some restores, but is more likely to repeat the behaviour described above for the failed cold boot.
Attached is a file with some snippets from dmesg around the time of the wireless failure, and the log of what it does after a remove and re-add for comparison of the "correct" messages.
i have just installed 10.10 under wubi, first time trying to use this network card under ubuntu. works fine on XP where it connects with good signal strength to a zyxel p-600 b/g router (my 3 other machines also connect fine to this router)
i am using WPA2, it takes 30secs to 1min to connect in the first place, then runs slowly and with intermittent disconnects, reports good signal strength in network manager.
i have been fortunate enough to have 3 machines that run ubuntu flawlessly out of the box..
I have set up one of my linux box as link load balancer for two ADSL connection. After deployment, I have found out that instead of being fast, it has become slow. What I have observed that my request get out to internet but comes back intermittently. Is this a standard scenario ?
I have two motherboards, MSI-6702 (64 bit single channel) and MSI-7511 (64 bit dual channel), I have two identical D-Link wireless cards and am running Kubuntu 10.10 on both systems. 7511 recognizes both wireless cards and connects to the Internet.The 6702 shows wireless grayed out on the connections page. The built-in Ethernet card has given out on both. I think I disabled it on the first system to have an Ethernet problem and wonder if I need to do it on the second. I would have tried it already but can' t remember how.
I'm having problems with my internet connection; it seems to be working fine then every other click of a page there is no connection, then I click it again a second later and it works. I am using a wired network connection plugged into an addon wireless router.
When I use ping under network tools it seems to be fine, then freezes halfway through and doesn't receive those few packets, giving me a transmission percentage of about 70%.
I need help with connecting to cdma mobile broadband for a tethered samsung phone. When I first installed Suse the phone icon on the network manager icon was all i needed to do to connect to the cdma network.After rebooting later the icon is gone and i cannot manage to connect. The connection is still there, but it is as if the computer no longer recognizes my phone as a modem. Well sense i just installed i figured lets try reinstalling to see if it was a bad installation. It happened exactly the same again. If anyone has any idea how to get network manager to allow me to connect to the internet again i would be grateful.
I have a Dell laptop with a bcm4312 wireless card. Every once in a while though, the laptop is unable to send or receive any data for 30 seconds. The connection is not dropped, and nothing shows up in any system logs. Both the wl and b43 drivers have this problem, but it works fine under vista.
Just recently I've been having strange connectivity problems with my wireless network. The connection has previously worked fine and haven't had any problems with it. I haven't installed anything that would have affect it as far as I know. how do I go about testing the network to see where the problem lies? I'm running Ubuntu 10.10 with a Netgear WG111v2 wireless adapter and my guess is it is some strange configuration problem or a rogue application is eating up packets because the system works fine when I boot it up into Windows.
When I try to ping my router I'll usually get something like 98% packet loss. However in the output below, the network sprang to life half way through my pings so it went up to 63%. What other tools can I try to find out what's going on?

I have an old Tatung tablet pc, with touchscreen, stupid speakers and an atheros wifi card (AR5001X+). With XP, everything works reasonably well, and wifi connectivity is rock solid. I know I'm asking for trouble installing *nix on this machine, but if the wireless worked, I'd be happy. However... With an updated Lucid install, I can see and connect to open, WEP, and WPA(1/2/tkip/aes/whatever) networks. I get good speeds with every network I've tried, but after a minute or two, my connection speed drops to zero, only to recover after another few minutes. A few minutes later, the wireless dies again, then reconnects....
Both the router and the tablet show that I still have a connection, and the connection speed recorded by both does not change from the 'working' condition. I get nothing in the logs (router or tablet) and no indication (aside from transfers stalling) that there's any problem. The 'network history' part of Gnome system monitor shows the data rate dropping to zero, but a network monitor applet on the gnome panel shows transmissions and (later) recieves. Reported signal strength remains constant, and seems to have no bearing on the frequency or length of the dropouts.
I've tried the stock lucid drivers, the lucid wireless backports, and madwifi (currently on madwifi) with no change to symptoms. I did think that it may be to do with scanning for networks (iwevent showed completed scans as the dropouts ended) so I removed network manager and tried static configuration with /etc/network/interfaces . The problems persited (although iwevent is now silent) and I am now using Wicd with no change.

I see nothing toobad in these, so I ran a longer test - I bash'd a while loop to ping the router, run ifconfig and iwconfig, and spit the results into files. I concurrently ran a wireshark capture. All of these contain a lot of text/data, so I've attached them here. I can't see any connection between the output of ifconfig/iwconfig/wireshark while the ping drops, but I'm no expert.
I got a NetGear wireless router recently. Attached it to my Huawei (pardon the spelling) modem. I have a HP 540 laptop running Ubuntu 10.04 The wireless gets connected. But there's an exclamation mark almost all the time. Very frequently these days, the connection gets bogged down or websites just don't open at all. But the icon (with the exclamation mark) shows Active Connection. I don't know where to start looking for bugs. Seems odd. Wireless is connected, I can connect to sites, but there's the exclamation.. and sooner or later, connection goes off but the icon still stays the same with "active" label.
I'm having a bizarre problem where my network connection stops working randomly. At first I thought it was a DNS issue since Firefox simply chilled out on "Looking up [hostname]" until it timed out, but after further investigation (pinging IP's, "host" and "dig" being unable to reach servers) it became apparent that I couldn't even access the DNS servers i.e. the Wicked Connection of the East was most sincerely dead.
There are two strange things about this: one, there are no errors except "timeout". The network manager is happy, Firefox is happy until the lookup fails... Two, the failures only start *after* DHCP configuration. DHCP configuration never has any trouble sending or receiving packets. I'm going to try static IP and whatnot to see if that helps, more information later.
I am using open suse 11.3 with kernel 2.6.34 KDE is 4.4.4, I have Lenovo G550 laptop My system sometimes detects and connects the modem to internet and sometimes its doesn't detects and I am unable to connect to internet I have all the updates installed. Because of this I have to use Forbidden OS (windows)
I just upgraded to Ubuntu 10.10 because I was facing internet problems with previous Ubuntu 9.04 after I upgraded it with downloaded software. And now, 10.10 connects to wireless, but shows web-page some-times and repeatedly disconnects. Earlier it wasn't reaching Internet at all. Some of the topics here helped a lot. But this intermittent internet seems not going anywhere. Wired Internet connects easily though.
I've tried :-
-disabling ipv6..... first in Firefox, then in Kernel also -Setting DNS.....System> Preferences> Network Connections -setting static Ip
On my Lenovo T410 (openSUSE 11.4 KDE - 64bit) I have mobile broadband. Gobi-loader is installed and working properly. However when I try to setup mobile broadband connection the KDE Control Module crashes. Tried many times also after reboots, though KDE Control Module keeps crashing.
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 problems connecting on the net with my ubuntu. My driver is Broadcom Corporation BCM4318 AirForce One 54 I can see access points and i connected to access point called Zone 9 but the problem is that i was on XP entire life and i was connecting via broadband connection that requires username & password after connecting to access point So tell me how do I connect to internet on this ubuntu stuff
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)
We finally got internet in our apartment in China, but my husband was the only one home when the guy came to set it up (on his windows machine).
He connects by plugging in, then clicking a desktop icon labeled "Broadband Connection" where a box pops up with a username, a password box, and some buttons, one of which says "connect".
I am trying to figure out how to set this up on my netbook so that I can use the internet at home too. I have a feeling that even if I had been home when the setup guy came, he wouldn't have had a clue what to do with mine anyway.
On the WinXP machine: Connection Properties state that this is a PPPoE connection, with TCP/IP, QoS, and Deterministic Network Enhancer all checked. Under the security tab, unsecured passwords are allowed.
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 use a Huawei E 1550 mobile connection, which worked fine in Ubuntu 9.10.I've got it working okay in 10.04, having installed modeswitch. However, it will not automatically reconnect if it drops out. I can force a reconnection, only if I remove the dongle and then plug it in again. Although it shows in network manager, clicking on the list entry for the dongle, just produces a disconnected dialogue message. The only way to get it to reconnect is to remove the dongle and plug it in again.I know there have been a few posts about getting mobile dongles to work in 10.04, but I can't see any solutions to this little issue yet.
How to connect Ubuntu to the Internet through a broadband connection? I decided to give Linux a try, and I picked the Ubuntu variant. I have some problems with the Internet connection though. I have a broadband (modem-less) PPoE connection, and all the info needed in order for me to connect are the username and password (which I have).
I have attached the screenshot of the option which I select in Windows for making the same internet broadband connection. I am unable to find the same option in Ubuntu 10.04. Till now I was using the Pppoe Dialup. But now I am unable to configure this one.
I also issued the command sudo iwlist ttyUSB0 scan it gives this as output ttyUSB0 does not support scanning
I also issued the command sudo iwconfig ttyUSB0 essid "MTN DEFAULT" iT GIVES THE OUTPUT Error for wireless request "Set ESSID" (8B1A) SET failed on device ttyUSB): no such device
How can one find out the essid value of a broandband network? How can i connect to the internet from command line for a broadband network?
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)
