I am using BSNL broadband ISP and I am able to get network on windows os but not on my ubuntu.( I have a dual boot). I see Auto eth0 connected from the notification but when i am pinging [URL]... it says unknown host.
View 9 RepliesUpgraded To Ubuntu 10.04 The Other Day. And when I first installed it everything worked great except for my sound card which I fixed. But there was no problem with connecting to my Router via an Ethernet cable. Then I updated the video card drivers, restarted my PC and it wouldn't connect. It would try over around 1-2 mins then tell me its disconnected. No green light activity on the router / network card either.
I've reinstalled fresh copies of Ubuntu a couple of times now, Hoping to get the default settings back. But nothing has worked since.
I looked around the net and found quite a few people had this problem on previous versions of Ubuntu but it would seem most of there fixes were for there Version, so it hasn't helped me.
Heres some info:
ifconfig:
I've tried all the various things from dhclient to ifup/ifdown etc etc.
I'm running Kubuntu 10.4. My problem is that Network Manager keeps defaulting back to Auto eth0. I have created a new wired connection and set my manual addresses. I have ticked the 'connect automatically' button. Every time I reboot or wake up it reverts back to Auto eth0.I did have wicd installed but this was not reconnecting after wake up (said it was connected but I couldn't ping etc), this is a pain also.

I'm praying for some crappy syntax error, also in Network Connections... its now blank, the original auto eth0 setup is missing
When I log onto my Ubuntu 9.04 boot I am disconnected from the internet, on my windows 7 boot It works just fine, I have attempted disabling networking, power cycling the modem and router, and re-enabling networking, no dice though. hovering over the connection icon tells me that there is no network connection.
Opening the edit connections window tells me that there a wired connection called Auto eth0 that is set to never, and that is all that I can find. I hunted for other forums on this and found a few but none with a successful resolution.
I want to set my desktop IP address to always be 192.168.1.2. The NetworkManager connects to the network automatically and the IP address is assigned randomly. I can set up another connection in NetworkManager and always change over. But is there any way to make the default eth0 interface to be permanently set to a certain address (using NetworkManager, not ifup)?

Now Ive installed on a couple of my Laptops, and even had a few friends convert, and for the most part everything is hunkus doris, cept one small issue thats keeping me from slapping it on my trusty laptop. I'm lost as to what the problem could be. Ive tried just about all I can think of, but I use sprint mobile broadband to connect to the net and then use Network Manager to share this connection with the laptops and Palmtops around the house. I can get my sprint modem to connect thats not a big problem the problem is now I cannot get the Auto Eth0 to connect to send out as a share. It just refuses to connect. Now this is not a Lubuntu problem at all Im sure its somehow a Lxde problem, as Mint Lxde, PeppermintOS, and so on do the same thing, refusing to connect Auto Eth0 while Sprint is connected. Any Gnome based distro this works flawless, as does Xfce distros, so Im sure this is somehow something within Lxde. Im sure its down to just "missing" a file or some stupid overlooked thing.
View 3 Replies View RelatedI'm trying to use network-manager in sid and it's incredibly frustrating because every 2 minutes or so it seems to scan for wireless access points, during which time my SSH connections completely hang and screw up. Pings start dropping packets as well. By doing an "iwlist scan" I can reproduce the behavior. Has anyone else dealt with this? I haven't been using network-manager, but I am currently due to mobility and needed VPN functionality... WICD with no network-manager works better but there's no gui-based VPN support. I've got an Atheros wireless device and I've read that supposedly it should be doing background scanning since kernel 2.6.32, but I haven't seen anything like that, and I'm on 2.6.32-5-amd64 currently, 2.6.32-3-amd64 behaves the same too.

View 9 Replies View Relatedso I now have 4 Ubuntu Lucid LTS installations - terrific - but the alternative Ubuntu boot on this particular PC (all made from the same Live CD) does not have any eth0 configured, so I cannot reach even my router. I can look at the eth0 properties with "Network tools" and it has no IP or MAC. I have the network notification gremlin installed but it does not appear on the top panel. {"eth0" hardware works under Win XP, hence this post}.
I'm a novice at Ubuntu, and I am at a loss. I realise that networking is supposed to be automatic, no 'tool' should be needed, but what can I do when it has not configured?
I'm using Easytether through my HTC Droid for interwebs running Ubuntu 10.04. However I also have a home network. However when I hardwire into the network via a D-Link router (Auto eth0) my internet no longer works. The same is true when I plug in my iPod. The Droid loses it's connection. What is the problem?

I checked " activate device when windows starts" in network configuration. still it is not auto connecting and after connection the network icon is not changing to connected status although it is connected.
View 4 Replies View RelatedI currently have a command line Ubuntu 9.10 installation.
I wish to be able to have either both wireless and wired connection working
For example: when LAN is connection the wireless is switched off, when LAN is disconnected the wireless comes up (WPA2)
I know that the Network Manager in Gnome does this auto switching for you but I need to know how to do this in command line only.
I am unable to connect to the internet at work through the ethernet, previously working. I am not sure of the origin of this problem -- the result of an update or something that I did to the network settings.
In the NetworkManager applet is says Auto Ethernet is connected but I can't ping anything by name or ip address.
The wireless still works without any problem.
I have tried following some of the other threads on similar issues but the fixes proposed on them have not helped to date. And I may have mangled some of the settings files somewhat.
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?
View 2 Replies View RelatedI recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
Code:
#!/bin/sh
case "$1" in

So far as my knowledge goes, /etc/network/interfaces is supposed to contain a list of all the available interfaces. But my /etc/network/interfaces looks like this,auto loiface lo inet loopbackBut I have a perfectly working eth0 connection. Why does not it appear here?
View 9 Replies View RelatedI was browsing the net very well and without any issues for the past 15 days since I installed FC14. Fantastic experience and then suddenly yesterday after nearly 2 hours of a smooth online session I lost internet connectiivity.At that point I noticed that the network icon on top was showing a red cross. After clicking on it I could NOT eth0. I specifically remember seeing it there before.I checked the cables and the setting to no avail and just could not get it back. Any idea what I should be doing to see eth0 in the connection?Also FYI I have been noticing this from day one since I installed FC14----When going through administration-->network-->One cannot see the red and GREEN activate button that I am used to seeing in FC9. In fc14 its greyed out. So I actually had to go and enter the /etc/init.d/network start command to change the status from inactivate to activate.Also the network manager does not seem to be managing eth01 as it does not appear as an entry in its console.

View 4 Replies View RelatedOn the 25th of January, one of my computers randomly stopped being able to connect to the Internet. It was running a dual boot (Ubuntu 10.04.1 LTS & Windows XP SP2), and is connected to the network via an ethernet cable (no wireless). According to the Network Manager, everything is working okay (there was no change from when I was able to access the Internet).
When I would use Firefox, I would get the message "Waiting for (page)...". However, this is not a Firefox only problem, as every program requiring Internet access (e.g. Evolution) is unable to connect to the Internet.
I compared the Internet settings to those of my father's Windows XP SP1 computer, which is able to connect to the Internet. There was no difference, except for the IP Address and Hardware Address. Because of this, I incorrectly deduced that either the actual Ethernet cable or the wall plug was faulty. I tried using a different cable and connecting to the Ethernet wall plug used by the aforementioned computer. Nothing changed. I was still unable to connect.
I didn't worry about it until Tuesday, when my other computer had exactly the same problem. It is running a triple boot between Ubuntu 10.04.1 LTS, Ubuntu 9.04 and Windows XP SP2, and I am unable to obtain Internet access using any partition. As with the previous case, my computer showed no change in the Internet settings, and the computer also shows it as being connected to the network. It is also connected via an Ethernet cable.
I have a Toshiba Satellite L505D-GS6000, and I installed Ubuntu before and it worked flawlessly until I decided that I had to go back to Win7 because of certain program compatibility issues.I'm back here trying to set it up and am having no issues except for with my wireless. I can see all of the SSID's, I am able to connect to my wireless, and it displays that I have been assigned an IP and all of the other settings given by DHCP.
I have been trying to fix this for hours, googled, searched these forums, and have spent time with some people on the Ubuntu IRC channel and we are unable to come up with a fix.

The strange thing is that although nothing will load when I try to visit facebook.com, google.com, or any other website... I opened the update manager and I noticed that it would download for 30ish seconds, stop and do nothing for 60ish seconds, resume for another 30, stop, resume, etc. until it finished. I am able to ping my router, and 8.8.8.8, but I am unable to ping [URL].
I run an Ubuntu Server in a Virtualbox environment. Setup works fine. In virtualbox, I accidentally hit a button that generates and assigns a new mac address for the network adapter. Since then the machine does not bring eth0 up. I tried the following ifconfig eth0 down; ifconfig eth0 hw ether macaddress; ifconfig eth0 up. Then restarted networking.
View 2 Replies View RelatedI've got access to my LAN and the Internet via my wired ethernet connection. I'd like to share that access with my iPod Touch (device shouldn't really matter) via an Ad-hoc wi-fi network.
This tutorial in the docs seems to describe the right setup but is very out of date (7.04). Instead I found this tutorial and followed it to create the Ad-hoc wireless network. I was able to connect my touch to the resulting ad-hoc network without a problem, but I didn't have LAN/Internet access.What's the next step to get the clients on the ad-hoc network out to the Internet?I found this page in the docs that says I'd need to install dnsmasq-base and uninstalling dnsmasq. I checked and dnsmasq-base is already installed but dnsmasq is not. I do have dnsmasq in /usr/sbin but the package description makes it sound like this should come with dnsmasq. Is the page out of date? Will uninstalling dnsmasq cause other problems?
i have limited experience with Ubuntu and Linux for that matter. i know my way around for the most part but i come from windows. anyway. i have 6 dell gx260 computers. i also have a netgear 8 port Ethernet switch. now im just trying to get the computers to see each other. simple for me in windows. but i have no idea where to start here. it just says connecting to eth0 then network disconnected. and thats it. for now im just working with 2 of the computers. the others are not set up yet. i have been googling for 3 days and got nothing that helps. (my goal after they see each other is to share files back and forth. and also to have one of them control the others with some type of remote desktop. but thats for another day.)

View 9 Replies View RelatedI upgraded to 10.10 the day it came out, and haven't had any problems with internet stuff. My wireless card works without any proprietary drivers. Last night, the computer stopped connecting to the internet. I am still connected to my wifi network, but I can't do anything online. I had assumed that my internet connection was just down in general, and tried resetting the computer, shutting down the computer and then turning it on again, and rebooting the modem, but then my Xbox connected, and my laptop running 10.04 connected, so I'm confused as to what is going in. Any ideas?
