Ubuntu Networking :: Automatically 'redial' ADSL Connection After Power Failure?
May 4, 2010
I use an ADSL connection which I 'dial' using the Network Manager. My laptop is connected to the modem through an ethernet cable.
The thing is the place where I stay is prone for power failure. So the modem goes out with the power. It comes back on within a minute when the power is restored but Network Manager doesn't seem to automatically re-establish the connection after it is lost once. I have to manually do it. Hence most of my downloads do not get done.
is there any problems with making adsl connection in ubuntu 10.10. Recently I've had ubuntu 10.04 and there was a problem with making adsl connectio so I was forced to you terminal in order to connect to internet. I'm asking you this because I'm planing to install Ubuntu again but if there is still connection problems then I wouldn't install ubuntu
I'm using ADSL connection as a way to access internet.All of us know that in windows we can get configed easily.But it is a little more difficult in Fedora.How can we config ADSL connection in Fedora 10?My modem uses dynamic ip.
I am new ubuntu user . I installed - ubuntu desktop v9.10 32bit. I have BSNL (Indian Telephone service) broadband connection. In Windows 7, BSNL broadband connection is working fine.
Now in ububtu I try to establish ADSL connection using following command: "sudo pppoeconf". It open a console based wizard and I'm able to create the connection. But this connection is sustain hardly 4~3 minute, after that it is disconnected. So, Again i have go through the same process again and again.
have Karmic Coala runing on an IBM thinkpad X.41. Works great. My home network is all ethernet so I have a router , CAT5 cable to laptop.A coupleof times I've had power outages The laptop carries on as it's on battery power. When the power comes back , the router restarts, it reconnects after a few minutes but the laptop doesn't reconnect to the network seamlessly. On some other Linux distro's I've had running /etc/init.d/network restart will refresh everything. On Ubuntu I have /etc/init.d/networks but running restart In the end I needed to reboot the laptop to get the network back on.Perhaps this is a power management issue with the laptop ethernet card i.e losing power powers down the card and it never comes back up properly.
I have a pppoe adsl connection. When I disconnect and try to reconnect, network-manager keeps asking for my password. I type it again and again with no success. When I reboot, it works again. On ubuntu, I use pppoeconf and it works well. So on Fedora I made a connection with pppoe-setup but neither ifup nor Code:
pppoe-connect commands work. When I type Code: pppoe-connect , it says Code: /usr/sbin/adsl-start: line 217: 13409 Terminated $CONNECT "$@" > /dev/null 2>&1 . When I type
Ifup ppp0 doesn't work either. However, with exactly the same settings, ubuntu connects to the internet.
My router/adsl modem is not connected to a power supply so when power goes and comes the network will do a re-boot. Now the problem is my OpenSUSE network won't come back on! I set the static ip as Autoeth0 to eth0 however when network updates I losse eth0. Why is this happening? Why doesn't the PC simply re-connect? Can I do it via command line?
I can't connect internet using ADSL modem of bsnl.I am new user of linux(fedora8).To do so I go through system>administration>network configuration and trying to activate xdsl modem and ethernet but unfortunately ethernet does not seems though there is a ethernet card.Here it should be mention that in my windowsXP partion there is no problem for internet connection.so what can I do next?
Using a set of instruction given to me, I was able to set up a Macintosh system running Mac OS X to successfully connect to a virtual private network.I then tried to adapt those same instruction to configure a system running Fedora Linux 12 on an Intel Core2 Duo system.However when I try to connect using the NetworkManager Applet, I get an error that saying the VPN connection failed, with no clear indication of what the actual problem is.What can I do to troubleshoot this problem and find out why the connection is failing?
I'm running Ubuntu 10.10 netbook edition on a Dell Mini 9 - worked around a few wireless issues on setup and connectivity has been fine, but now I'm suddenly losing wifi when I unplug my AC adapter. It still shows me as connected, but when I try to view web pages in Chromium, it will load pages for a few seconds, and then suddenly cuts out - though it still looks like it's trying to load the page.
It's the same if I boot on battery power - it will keep trying to connect to wifi but won't until I plug in the adapter. I'm assuming this probably has something to do with my power management preferences in battery mode, but I'm still pretty new to Ubuntu, and I'm not sure how to fix this. I've played with the options in power management, but I have a feeling there has to be more. Can anyone help me? This has been really frustrating.
I have a problem with my wireless where when running the laptop from the battery the connection is very slow. When the laptop is connected to the power supply everything is fine, but the moment it's disconnected and run on the battery the speed drops when browsing the Internet or accessing files on other computers on my network.
The laptop is a Samsung SF310 Wireless chipset is BCM4313
In attempt to fix this I installed the latest drivers from the Broadcom site using this guide. When I enabled these drivers everything worked well. I did speed test and got the same speeds I get when connected via Ethernet:
Ping 51ms DL 4.31 UL 0.65
So I set the drivers to load at boot using this forum post as a guide as the steps in the Broadcom guide didn't work and rebooted the laptop on battery power. The wireless connected fine, but the slow speed problem had returned. Running a speed test got the following results
Ping 235 DL 0.54 UL 0.30
So I ran iwconfig when running from battery and then from power supply. Code: xxxx@xxxx ~ $ iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11 Access Point: Not-Associated Link Quality:5 Signal level:215 Noise level:160 Rx invalid nwid:0 invalid crypt:0 invalid misc:0 As can be seen the signal quality is 5 and signal level 215
Code: xxxx@xxxx ~ $ iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11 Access Point: Not-Associated Link Quality:5 Signal level:214 Noise level:164 Rx invalid nwid:0 invalid crypt:0 invalid misc:0
And when connected via the power supply the signal level is 5 and signal level 214. There may be some kind of power saving issue, although there are no relevant setting in the BIOS and I can't see anything in the various wireless control pannels. I have other wireless drivers and there are no problem with those.
One of the (many many) problems that I had with Ubuntu 10.4 was that I wasn't able to connect using a wired. It really came to me as a huge surprise, because that's a problem that I have never encountered. I had dealings with wireless-issues in the past. But never a wired connection failed. The thing is that we (in the dormitory where I live) had a network problem recently. A hardware piece got fried and we weren't able to replace it for about 3 weeks (go figure :X ). But in the past 3 days or so we're back online. The thing is - none of my neighbours (all of them are using Windows) has network issues now. Usually it was on the contrary - I was the one who had beautiful connection while they had to deal with a load of d@ng. That said - I made a fresh install of Ubuntu 9.10. The problem got resolved and I was as happy as a chick during her first wedding night with Don Goivanni in her bed. BUT after I updated (note - update and NOT upgrade) my system, I was suddenly unable to use the wired connection. The strange thing is that the NM says that I am connected AND I even get some short bursts of network traffic (last for 2-3 seconds) but usually not enough to load even a simple web page. Ping always returns 100% loss no matter how long the package burst lasts. I have slept this night for about 3 hours looking for a solution. None has been found so far. I don't have WAPs at home so wired connection is the only way for me to use this modern thing called internet.
Sometimes either due to a power outage or due to lightning I turn off my Wimax modem and continue to use my laptop on the battery.Then when I turn the modem back on, there is no internet connection.Here's what I've tried:
1. turn off and on the network connections - right-clicking on the icon on the bar on top of my screen.
2. turn off and on the dsl-provider connection - no effect.
3. When I tried to re-do pppoeconf, it says that there's no response from the concentrator.
This has happened a few times in the past and the only thing I can do to go online again is restart the computer. And it works.Now on Windows, the double-computer icon showing a network indicates connectivity AND data movement. Unfortunately we don't have this on Ubuntu.I'm just after a restart and I'm online now. But I'd like to know if there's a way around this without having to restart.
I have always been using one ADSL connection (ppp0) with squid.My question is, is it possible to add another ADSL connection to the same box.If yes how does the route works.Is it possible to switch to one ISP to another by just changing the route?

After an update this week I noticed some strange things with the network. 1. The network connection doesn't activate itself automaticaly. Have to do it every time when booted up. 2. At the taskbar icon the previously "Auto eth0" changed to "System eth0". I guess this is kind of connected to the first issue 3. I can't connect anymore to the windows network -Times out (also worked fine before) How to set it up to the "old" way?
Since that time I moved to Archlinux and I love it. I do however run lubuntu live from a USB for my work PC. I am having a problem with it. I think it's okay to post here because the core of the system is still Ubuntu. I don't think LXDE is the problem. I start up the live environment and it says 'wired connection connected' but I can not load any pages or do anything.
I thought it may be a problem with configuration so I copied down (from Windows) the IP, Subnet, Gateway and DNS. I put them in manually and it doesn't say connected any more and still no connection at all. I am unsure what to do from here. I am not really familiar with Ubuntu enough to try much. I tried to 'dhcpcd eth0' but dhcpcd isn't installed. I guess the default Ubuntu network manager has dhcp enabled automatically.
I downloaded openSUSE-11.4-KDE-LiveCD-i686.iso from software.opensuse.org: Download openSUSE 11.4 yesterday.It's a liveCD,not a DVD. Then I used a dd command to make a live USB by the instruction from this page:SDB:Live USB Then I shut down the computer,and boot from the usb. I went to the yast--DSL to make a new adsl connection.But after I configured everything,yast told me one package needed.The package's name is "linux-atm-lib". I haven't connected to internet.How could I do to install a package and make a connection?
Now I am downloading a DVD.Does a DVD include the package called "linux-atm-lib"?
I was upgrading my ubuntu(9.10)/xp machine to ubuntu(10.4)/xp . but there was a power failure and was running in backup for 15 min. But after that the system shutdown automatically. Now when i boot, grub appears and after selecting the ubuntu partition i get a error saying cannot find device.
While using my computer the other day (I was sending an email) it suddenly turned off. I didn't get any low power warning, but I was running on battery and had my iphone charging from a USB port.
As I didn't think there was low battery, I just turned it back on again. As it was booting I saw the battery light flashing, indicating low power. I went to get the charger, but before I got it, mid boot-up it turned off again.
This seemingly damaged something hard-disk-wise.
Upon turning it on again it dropped into busy box with some message similar to this:
No init fount. Try passing init= bootarg.
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu7) built in shell (ash) Enter 'help' for a list of build in commands
That's not the actual message (copy pasted from another post) but the message is VERY similar to that.
If I "exit" busy box, I get a load of message about "kernel panic" before it freezes up.
I have booted a live USB (what I am using now). I thought since it wasn't cleanly unmounted, simply mounting and unmounting would do the trick. I was wrong.
Code: ubuntu@ubuntu:~$ sudo fdisk -l Disk /dev/sda: 250.1 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes
I had previously ran e2fsck (after checking it was unmounted) but it wouldn't run also because it was reporting that the device was already mounted, busy, or being exclusively used by a process.
I don't want to do any more for fear of causing further damage.
I am astounded that such damage can be caused so easily!
