Ubuntu Networking :: Internet Keeps Cutting Out?
Jul 12, 2011
I recently moved into a place where I have no control over (or access to) the modem or router, and I've encountered quite an annoying problem. My Internet connection keeps cutting out, not for long periods of time, but just enough time to stop videos from buffering and web pages from loading, and it happens often enough to become a regular thing.
I know there are ways to fix this problem, but unfortunately I'm in a position where I can't. So my question is; are there any external "fixes" I can do to keep the Internet connection alive or to retry connecting every time it fails? Like perhaps a Firefox addon or something I can install?

I've had this problem for a while and wondering if anyone has an idea what is going on.
I'm running 9.10 on a computer at home, and when I VNC into it from my Mac at work.
When I do a right-click copy or ctrl-c, the vnc will crash and won't connect again. I can reach the computer with SSH and reboot, but it's kind of annoying when it does this. Has anyone seen this before and is there a fix?

I've been looking around for a Linux variant which will install only the software I need rather than everything Ubuntu (for example) puts in by default. This is to create a virtual machine in Virtualbox which has bash, apache, python, perl, SQLite, openssh and a few other programs but nothing else. I'd prefer to go with Ubuntu if possible but another modern distro would do as well (I like using apt-get and yum rather than downloading/compiling etc).
SuseStudio.com, which is probably the best so far.Ubuntu 9.10, by pressing F4 to get the boot options on the install disc, but there is no minimal installation (oops! had the alternate disc instead of the server disc).Arch Linux, slightly confusing install procedure but I might go back and try again.Gentoo, started well but fairly soon the HD on the virtual machine went to 2Gb, even before the installation had started in earnest (I'd partitioned the disks is all).I realise there are various "small" Linuxes around like Puppy, Feather, DSL, etc, but they seem to be aimed at desktop users or as a techie's toolkit, and I want a small-as-possible server distro which can be managed with tools like apt or yum or similar.

I'm just looking for a good mpeg cutter for my Ubuntu laptop. I currently use video redo on my Windows PC but that is also my HTPC and is hooked up to the TV. I would prefer not to do it on the TV because of possible burn in issues and would love to be able to take the mpeg files recorded on the HTPC and cut them on the laptop but haven't found a really great application to do that.

Judging by the number of responses (close to zero) to other threads about powertop on this forum, I have little hope in getting any answers. However, I do not know where else could I ask. PowerTop tell me that even after applying almost all the tips and tricks from lesswatts.org, my laptop still consumes over 72 Watts while idling.
Code:
< Detailed C-state information is not P-states (frequencies)
1.60 Ghz 0.0%
800 Mhz 100.0%
Wakeups-from-idle per second : 451.1 interval: 10.0s
Power usage (5 minute ACPI estimate) : 72.5 W (0.3 hours left)
Top causes for wakeups:
[Code]...
Suggestion: Enable USB autosuspend by pressing the U key or adding usbcore.autosuspend=1 to the kernel command line in the grub config This is when I am not touching the laptop. When I am surfing the web or listen to music, it goes up to 2000+ wakeups! How do I cut it further? I am getting like 20-30 minutes max on battery and this is unacceptable cause in Windows I get at least 3 times that.

I'm having video issues with my graphic card while using Ubuntu 10.04 LTS 32 bits. When I'm watching video (Either on ....., or a dvd or whatever) There are horizontal lines cutting the video, like when there's very fast movement it doesn't render the video smoothly and so I get to see like vertical divisions, I don't know how to explain it exactly. I have a driver installed, one that installed automatically when I turned normal effects on, but I don't even know which one it is, I'm very new to this.

I have an html file like this
HTML Code:
Some more HTML code... I would like to cut the above text so i get this: Sometext on multiple lines like this.Sometext on multiple lines like this.Sometext on multiple lines like this. Sometext on multiple lines like this.Sometext on multiple lines like this.
There are other HTML files with similar cuts I need to do, but once I have the method for doing one, I am sure I can do the others.
I think the two logical strings to cut between would be:
I am not sure if these strings are always the start and end of the line respectively, is this makes a lot of difference! Then the HTML tags would need to be stripped to get the text on its own.
I know the commands for removing tags, but searching for a string like class="IOSSectionTitle", and cutting everything before it etc is something I am finding challenging.
Just thought I would add that the HTML does not nec. appear on logical new lines throughout the file and there may be unexpected new lines, but as far as i know the class="IOSSectionTitle" and <img always appears as a string without any new lines between those characters.

Since upgrading to 11.04 I have come across an issue when syncing my music to my Motorola Defy mobile phone. I have a large collection of music, the vast majority of which is ripped from CD and stored in FLAC format. I use Banshee to sync some music onto my phone by dragging and dropping. Banshee converts FLAC on-the-fly to OGG prior to copying the file to my phone.
Since installing Ubuntu 11.04 any songs that i have since synced appear to be cut short. The files seem to be of about the correct size, when the music player starts playing the track it shows the correct total length of the song in the timeline bar but the songs get cut short, usually at 5 seconds into the song but a few seem to last about a minute before skipping to the next.
This morning I tried converting files using Sound Converter and setting the Music folder on my Defy's SD Card as the destination folder. The files all appear to be of the right size, show the correct track length but only play the first 4 or five seconds. I used my other computer, also running Ubuntu 11.04, to transfer a few files and these work just fine.

I have had some issues since installing Fedora 11 on my desktop (well not after I installed it, once I installed the updates). Anyway sound was cutting out, videos were jumping, speeding up with no sound etc online such as ....., when playing local songs and videos etc. Anyway I followed this guide [URL] and that fixed my playing of online videos, music and when I play local music in totem etc. IN fact there is no issues with sound in those.
However; when I try to play a local video in any medial player it jumps sound, crashes, if it starts playing sound it will cut out and if I move the video forward it cuts out and sometimes crashes the video player. Any ideas why that guide fixed all online video and local MP3 but is till messed up playing local videos?

I'm developing an embedded Linux (it is almost over now). What I'm struggling with is the system goes unstable by cutting power source frequently and it does not boot anymore. It even does not perform fsck. The system just has a XFCE with a fixed Qt App autoloaded to display some charts. My question is that how commercial embedded Linux distros (like Wifi AP's management Linux, ...) avoid this problem?

I am trying to connect my desktop to my laptop over a non-internet connected LAN, but when i enable the LAN connection on my desktop (the one with the wireless) its internet stops working.
it is a very similar problem to this except that i am using ubuntu for the machine with the two connections.
right now i have my wireless on the 192.168.1.* address space, while the LAN is to be on 192.168.5.*
note: my goal is not to share internet with my laptop, just be able to connect to it and the internet at the same time.
desktop: ubuntu 9.10 , wireless and LAN
laptop: windows xp, LAN only

On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.

I've been messing around with debian A LOT, getting to know it, seeing what makes it run. I recently screwed up big time and nearly rendered it unusable, but I managed to slowly repair it. However, I was unable to do any kind of auto-DHCP connections. Now when I put eth0 up, the connection will cut out after about 5 seconds, and I can't connect any more until I either restart the networking service or do ifdown then ifup.So can anyone suggest to me any logs I should look for, or any packages I should make absolutelyure I have installed and configured properly? Any config logs that need posting

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

I have a server with two ethernet ports. I configured eth0 to be static, set at 10.1.10.148. I plugged in another router into the other ethernet port in order to configure that router. I configured eth1 to use dhcp. Using /etc/network/interfaces rather than gnome network manager. When I did this, I lost internet connectivity (internet routes through eth0 of course)
- Why did I lose internet connectivity?
In order to recover internet activity, I had to disconnect the new router on eth1 of course, and do sudo ifdown eth1. That wasn't enough however. After rebooting numerous times and pulling out my hair, I finally tried configuring eth0 as dhcp, rather than static, and this fixed the problem.
- Why didn't sudo ifdown eth1 solve the problem? What information was saved between reboots that somehow remembered that I plugged in the new router? Because my thinking was if /etc/network/interfaces was identical, and the network topology was identical, after a reboot everything should be restored, but it wasn't.

I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.

I suffer enormously from net addiction (as well as gaming addiction and related behavioural maladies).I've had revelatory success in controlling my time online-and, in general, in front of a screen with unproductive applications- by locking my monitor's power cord into an Ems PowerCop (the key to which I keep at work). Writing and journaling, I do on an AlphaSmart Neo. However, I could really use a tool to allow me to edit and typeset my writing (and only those tasks).I'm considering buying an ultra-low cost net-book.I want a netbook because it's the cheapest way to keep the display power fully dependent and integrated with the machine---I can't have something that will allow a simple means of working around the Ems PowerCop. Also, since it lacks an optical disk drive (and since I'll be keeping my usb drives at work) there will not be an easy way to reinstall the operating system. However, before I buy anything, I need to know that, after installing/configuring all of my preferred settings for vim and La/Xetex, there is a way that I can cripple the netbook and all of its applications so that no internet access is possible.
The Cherrypal Africa can come with either Ubuntu, Debian, or its own Linux blend, Green Maraschino. If it ends up being either Ubuntu or Debian, what can I do that will irreversibly (at least, from a software level---a hardware level would probably require damaging the usb ports, which I don't want to do) disable its ability to try to communicate with the internet (including the software repositories)? I'm hoping for a particular system file that I can delete rather than the addition of a command somewhere that would be easy for me to undo when I'm bored out of my mind and want to see what Wikipedia has to say about the glycemic index.

I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.

I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

I'm not really a newbee in Linux but I am a newbee in networking. I have both a Ubuntu laptop and a Gentoo desktop computer. I have just bought me the MBR1000 Cradlepoint router and it works great with my Verizon USB 760 modem plugged in it. I can now send and receive email on my Ubuntu laptop. I like it.My Gentoo desktop computer is just sitting there with no Internet access because my Verizon modem is no longer plugged into it but plugged into the router instead. Only my laptop now has Internet access. The laptop has an integrated wireless card built in the MB but my desktop has no such capability.
Is there a way (besides buying a wi-fi adapter) to get Internet access on my desktop computer through networking so that the router would give both computers Internet access at the same? My Gentoo desktop does have an ethernet adapter that perhaps I could useThe router has several LAN ports and one WAN port, both unused.

I got a HP netbook. Every time I turn on the computer, for a brief maybe 3 minutes the internet works. Then after that for some reason it turns off. I have no idea what to do and it took 4 hours to get the wireless to work, but to my dismay it keeps turning off after 4 min! It can find the router and the network, but it won't connect again after 4 min.
