General :: Loss Of Internet Connection After Update To Ubuntu 10.10
Oct 15, 2010
Not sure this right place for this. After updating from Ubuntu 10.04 to 10.10 lost internet connection - was instantaneous loss. Wired connection computer to router. Icon on computer shows "wired connection 'auto Eth0'active" The router shows line connected ok. Computer shows connection is established. Connection information menu shows details such as IP address broadcast address and other details. Where do I go from here to reconnect to internet.

Loss of internet connection after upgrade from 8.04 to 8.10 Like the title says, I lost my internet connection after upgrading my Ubuntu system from 8.04 to 8.10.I used the downloaded automated method. It appeared to work fine on its initial reboot into 8.10. But I noticed the internet icon indicated loss of connection. Even so, I was still able to browse the net through Firefox. But then when I rebooted the next day the opposite was true: the connection icon indicated connection, but Firefox would not actually connect, nor would update manager. It has been like this since. This is a dual boot machine, and the Windows XP Pro side still connects to the internet as usual, no problems.So how can I make my new 8.10 system connect to the internet?
I use a Motorola SB4200 cable modem

I've been running 10.04 since it came out basically and my internet connection has been fine. After I got the last set of updates that came up on the update manager (which if I remember mainly contained an updated version of the latest kernel and a couple other files) my internet connection speed went from a decent browsing speed and file transfer speeds between 80-200kbps to an almost dialup browsing speed to file transfer speeds of a about 7.5kbps its very significant and very annoying it took 20 minutes just to make this post.
Also I've already tried changing my ipv6 settings.

I tried to download some software from the Ubuntu software center, and it does not download. It does not give me an error message, it just stays at 0 bytes. It eventually tells me to check my internet connection. (this does not make sense because I am using it to write this thread) I checked synaptic package manager for correct proxy settings and it was ok. I ran
Code:
sudo apt-get update
but to no avail. I am using wireless, and recently dissembled the computer to disconnect the CMOS battery, but I think that it was put back together properly.

I plan to install F12 (Fedora-12-i386DVD.iso) in a location where there's no Internet connection, thus I'd like to previously download the updates in order to install them once completed the installation. How can i perform this ? can I download the updates that were released after F12 launch date from somewhere ? how should I tell yum or rpm to find them ?

I've been connecting to the Internet via Ubuntu 8.10 on my Toshiba laptop fine for ages now, but today it has stopped working. Yesterday an update came through relating to DHCP and, like all other updates, I installed it. And now my laptop can see the wireless router but it cannot connect to the Internet. (As I always install the recommended Ubuntu updates I didn't look closely at exactly what the update said, but I did see DHCP in the title, so this is why I suspect my connection is now broken.) Or can anyone tell me how to undo yesterday's update? I really wish now that Ubuntu had a utility similar to Windows System Restore.

i'm realatively new to linux am just getting my head around the command line, any way my problem today is, my network connection and networkmanger program have been deleted/uninstalled after i did a system update. im running ubuntu 10.04 32 bit. I have run of some commands which should be able to tell you whats going on. at the moment i'm using a live ubuntu cd to gain net access.
so the question is How do i restore my network connection and get my networkmanager program back without a internet connection. (i can download stuff to a memory stick and do manual install) Hope someone can shed some light on this, i know this topic has been covered before although each case seems slightly different to mine.

I have a new Toshiba Satellite L450, and decided to run Ubuntu, which is new to me. I am running a 64 bit Karmic, and there is no driver that works. So, to make a long story short: a friend helped me get a driver on my Desktop, namely: rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz We had it working, but when I let in the first large batch up updates, it kicked the driver out. I found instructions, installed it again. I let in the next updates, and it kicked out again, and this time the instructions don't work. So, I have two sets of questions:
1. Will updates always undo my wireless? Are there certain updates I should avoid if I want the wireless to stay up and running? (I just assumed the thing to do is just get the updates -- though I am guilty of having no idea what they were about.)
2. Did the updates cause one of my instrucitons to no longer work, or need to be modified?
They were as follows:
sudo apt-get install build-essential
cd ~/Desktop
sudo tar -xvzf rtl8192se_linux_2.6.0100.1012.2009_64bit.tar.gz
That 'sudo tar -xvzf...' operation is the one that stops me. Is there something to change in that line? It goes on:
cd rtl8192se_linux_2.6.0100.1012.2009_64bit
[Code]...
this worked the first time I tried it. I posted this earlier under 'hardware', and do not know how to get that post off, so I typed it here once I realized.

I adjusted my routes to use my ppp1 (VPN) connection for almost all browsing. Have I misconfigured something.? Some more background information: My VPN is about halfway around the world from where I am / my PPPoE connection. I've already changed my DNS servers in /etc/resolv.conf to Google's 8.8.8.8.I get around 2 kBps on Ubuntu and 50 kBps on Windows using the same VPN. =/

For most of today I had my internet connection dropping out on me intermittently. I assumed it was a provider issue, as it has been unreliable in the past. After it dropped out for good, and I could not print through network, I realised it was not a provider issue. All the other computers in the house were connected, including another ubuntu box. Only the MacBook Pro 5,5 was not able to connect. The network manager indicated I was connected to the network, throughout the whole time.
A number of restarts with the kernel I normally use (2.6.31-19) including one in recovery mode, yielded no change, but a restart with the 2.6.31-20 kernel resulted in connectivity. Finally, perhaps by chance, wireless started to work again on the 2.6.31-19 kernel, after I once booted into the Mac OS, and then back into Karmic. How I might go about diagnosing, obviously in hindsight, what happened? I suppose I should look in the log files, but I have no idea where exactly, and what to look for.

A couple of years back, just getting into Ubuntu, I installed Firestarter as an option to aid in networking. Realizing that it really didn't help in my plan, I now want to remove it.In terminal, I typed:
Code:
sudo apt-get purge -y firestarter
I rebooted, only to find out that I now have no internet connection.

I would like to have all traffic from the ethernet connection out through the wireless (basically using the box as a router) however I am having some trouble doing this.
I have done this before on Windows however I am having some trouble doing this on linux, I have tried using Squid Proxy however I am having some trouble using configuring/using it.
I am using Yellow Dog Linux however I am willing to change to any other distro as long as it is compatable with PS3 (as this is what im using linux on)

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 been having this problem for about two weeks now where Debian's network and internet connection randomly fails. It works perfectly fine and hosts all the services I need for a while, and then without warning all network connectivity fails. I can't ping any other network device. Regardless of how much I try to fix it, the only thing that works is restarting the computer. First, the server went 7 days without a problem; then 5 days; now it lasted 2 days. Judging from my Teamspeak server logs, it crashed today at 12:31. I grep'd through my log files and found this information:

I have three machines networked to my desktop which run a bunch of simulations in parallel. As they're running, I connect to them via SSH and screen to keep an eye on the runs and look at the output. They stay usually connected for days at a time. The SSH servers and client are running Fedora 14. Yesterday one of my coworkers accidentally yanked the plug on one of the servers while it was running. When I powered it up again, I started getting some odd connection problems. I couldn't connect to it via SSH initially because I got the Remote Host Identification Changed (RSA host key changed) error. I deleted the key in .ssh/known_hosts, which allowed me to connect, but it denied my password. I then logged into that machine locally, restarted sshd, and removed .ssh/known_hosts again. Now I can log in via SSH without problems. However, the connection dies with a "Write failed: Broken pipe" error every few minutes (as opposed to the other two machines, which stay connected indefinitely).
So my questions are:
1.) why would a power loss affect the behavior of the SSH server?
2.) why do I keep getting broken pipes now?

I had been playing around with wpa_supplicant, iwconfig and dhcpcd to get an x-less internet connection. However, this seems to have broken my Internet connection. I have reverted my wpa_supplicant settings, but every time I change networks, I must manually run
Code:
$ sudo /sbin/dhcpcd wlan0
in order to get a connection. Unfortunately, this sometimes results in
Code:
err, wlan0: timed out
warn, wlan0: using IPV4LL address ###.###.###.###
Using KDE 4.6 on openSUSE 11.4 32-bit. I want KNetworkManager to just automatically work.
Code:
$ ping google.com
ping: unknown host google.com

Machine: Win2000 Pro, AMD64 Athlon 2GHz, 2x80Gb HD, 2 GB RAM Symptoms: Running 9.10 with dual boot no probs for ~ 1 year. Decided to upgrade online via synaptic to 10.04. Upgrade went well no warnings, etc. On reboot all OS options present in Grub BUT clicking on Win2000 causes the screen to blank temporarily and then return to the Grub menu ie. no functioning Win2000 boot option. Ubuntu 10.04 boot yields blank screen with flashing cursor, a sudden stream of IO error messages (can't capture it but the lines look identical) then screen flickers and I'm at the purple log in screen and everything proceeds perfectly from there.
Observations: For the first time on any of my ubuntu installs (i've been using since 8.04 always installing from CD though) grub installation asked where I wanted it. In fact, the screen shows all devices with check boxes wth which to make my choice. That is sdb, sdb1, sdb2, ... , sda, sda1, sda2, There was a message that says that if in doubt install on _all_. Being in doubt I checked all the boxes: sdb, sdb1, etc. I noted in the message streams that followed after i continued that some lines had "... this is BAD ..." but since it was all rolling along very quickly no idea exactly _what_ was bad.
Action: I am not a linux newb but I am a grub newb. I fished the forums and googled only to come completely confused about what the problem might be or what to do. Example: have i overwritten my win bootloader? is my mbr corrupted? if i remove grub what will happen? if i remove and reinstall grub will i get windows booting back? if i use my win2000 install CD will it overwrite my whole disk (as many warn) or can i just fix the mbr? if I do the latter what order do i ie use fix mbr then fix boot? The info i've come across so far either doesn't address what happened to me, deals with other OSs (XP, Vista), or is applied to earlier editions of grub/ubuntu. Right now I have not found a clear step by step that addresses my circumstance. Would anyone be able to provide some guidance? I need the windows boot to run some software (Matlab) that btw will not work with XP/Vista (hence the reason i still have win2k).

I have a Hardy which last night asked for updates that included kernel changes. Today I find I no longer can connect using WIFI and have no sound. The GUIs are just not there and it's as if the controllers themselves have disappeared. For example lshw -C network reveals a Cisco Airon Wireless, but it's not listed as a wireless device, just as network controller.Can anyone advice me on how to approach this? Is it possible to revert changes or something?
