Ubuntu :: Desktop Is Not Connected To A Network
Mar 9, 2010
I just got Kubuntu loaded on my system, and this seems to be the closest forum for it. I have two simple questions:
1) What types of packages does Kubuntu use for installing programs and what's the package manager's name? (I don't remember from when I played with it last)
2) My desktop is not connected to a network (yet), so once I download the programs from a different computer and get them onto the desktop, how exactly do I get the programs loaded? I'm unsure if I can use the package manager to deal with files, or if it needs to pull from its own site.

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?

I'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.

I upgraded Ubuntu 10.10 to 11.04 on my IBM Thinkpad T41. [URL]... Since I did this, my gnome desktop freezes constantly after I connected to a wireless lan. It doesn't freeze immediately but a couple of minutes later. syslog gave me the hint that it could be a mistake in loading a module for my intel wireless card. syslog:
Code:

I have a compaq cq40-133tu laptop. I have windows vista ultimate and ubuntu 9.10 parallely installed. Most of the time i use Ubuntu for programming purpose. But for internet connection i have to go to windows. This is because ubuntu is getting connected to the network but is unable to access internet, whereas the windows can. I want to totally abandon windows. Recently i got internet connection in ubuntu for just 15 minutes or so when i ticked the option AVAILABLE TO ALL USERS. but after that the same story continues and iam not able to access internet. Details about Internet connection: This is not my connection, these signals come from nearby building. Its a wifi open public network.

On 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'm using Wordpress on Apache localy to keep a diary (it's convenient because of the tags).
When I'm connected to any network (be it wired or wireless) my Apache (and Wordpress, of course) works just fine. But as soon as I go offline, I can't access the web server neither through browser nor by telneting to the 80th port. Pinging localhost works just fine.Here is my ifconfig when offline and when online:Online:
Code:

I recently upgraded to ubuntu10.04 LTS via update manager. Previous version was 10.04 beta. After upgrading I am facing very strange problem.
1) If I start my laptop with network connection then all the folder under /home get disappear. When I do ls -l /home it says no folder found. As all the folder under home is disappearing it is giving so many errors when I login and as a result of this I am not able to start the gnome UI.
I tried to mkdir under home and it says cannot create directory.
I tried with root login but same error.
2) But it if I start my laptop without any network connection then I am able to see all the folders under /home and able to login successfully without any error.
I tried to mkdir under home and it was successfully.
3) I also tried this option, first start the laptop without any network connection and login successfully ( Able to see all folder under /home) but as soon as I plug the network cable and once it is connected all folder under /home disappear and system starts failing.
How to recover that user as I am having that user since ubuntu8.04 and lots of data and customization is there. My previous 10.04 beta version was working perfectly.

I'm having trouble pinging localhost, specifically, pinging localhost when I'm not connected to a network. When I try it keeps telling me the operation is not permitted:
Code:
matt@mubuntu:~$ ping localhost
PING localhost (127.0.0.1) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
if I connect to the network, start pinging then disconnect it continues pinging. Google seems to think it could be something to do with my iptables setup:
Code:
matt@mubuntu:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
[code]....
When not connected to network
Code:
matt@mubuntu:~$ route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
But as far as I can tell there isn't anything in there which would stop me connecting to the localhost (I also can't connect to my local apache instance when offline)... (It's worth mentioning that a couple of weeks ago I had the pc setup to share it's internet connection with a laptop, ala this guide, however I've since disabled the iptables rules and disabled ip forwarding.)

I 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?

I just installed 11.04 on my Samsung n130.
It does connect to the router, but when I open a page it does not load it...
It works ok with the ethernet cable.
Edit: after restoring from sleeping mode, it does not see any wireless network, I have to reboot.

I just came up with Linux/Xubuntu so I hope you I hope you'll excuse my "noobishness". I've Xubuntu 9.04 running on a laptop along with cups 1.3.9. I'd like to print on a toshiba 2820c which is connected to the local network. I tried to install it via localhost:631 what seemed to be working quite well since the toshiba is automatically detected and the driver (according to the printers manuel it's the same as for the 4520c) is already included. So I finish the installation and whenever I try to print something I am told that the job is sent and done but the printer doesn't even realise, that there was somebody trying to print something, at least there is nothing in the logs. I also tried to use the ppd-file from the toshiba-support but it failed again.

Background infoMy laptop (MySN MG6.c) is dual-booted with Windows 7 and Ubuntu 9.10, and connected to the internet through a router (Digitus DN-11004-O), which is set-up to use DHCP. The internet connection works fine under Windows, and my previous laptop, which also ran Ubuntu 9.10, had no problems connecting to the internet through that router.The network adapter is an Atheros AR8131 PCI-E (also detected as Attansic under Ubuntu)stem infoResults from running various diagnostics (I have removed the output that relate to the wireless connection, as I don't use it):

I just upgraded to 10.04 from 9.10 and I ran into few issues.
Laptop - Dell Vostro 1520
OS - Ubuntu 10.04 64 bit
Issue - My wifi connects to the network properly and shows connection established. But I am not able to browse. I tried ping and I didn't got any response. But I was able to get response when I use ethernet (wired connection) and I am able to browse. No issues with wifi card as my wifi is working properly from Windows and with the same network. I did a complete update again before posting this and it is yet to be resolved. Here are the output of some commonly asked outputs with wifi enabled and connected:
1. sudo lshw -C network

I had Xubuntu 9.10 installed on my computer and everything worked fine, i could download and surf the net pretty fast, but all of a sudden i couldn't do this anymore. The adapter was still connected to the network but when i opened firefox it worked for 5 seconds and then it would not load any pages, and even synaptic couldn't download any packages, even though it was still connected to the network. So i tried to reinstall network manager but it didn't work, then something happened and i couldn't access my Xubuntu anymore so I decided to delete the partition and install Xubuntu 10.04. I still have the same problem. What should i do? I am sure it is not a problem with the adapter because it works on the Windows partition.

I just installed Ubuntu 10.04, 32 bit, yesterday on my Dell Latitude 6500E and I am new to Linux. I can't find my HP LaserJet 3015 on my home network, even though it is connected to a new Windows 7, 64 bit PC thru USB. The other Windows PCs find it fine, and all 4 PCs can see each other on the network. So, I installed the HP software (http://hplipopensource.com/hplip-web...all/index.html) and that went smoothly, but the printer is still invisible. I also added Samba and that works great like everything else. I plugged the printer in directly to my Ubuntu laptop's USB port and it printed instantly. Now, if I could just print to the LaserJet on the network. Anybody got this one figured out? Does Wine provide a way around this?

I have a network printer directly connected via ethernet cable to an Ubuntu netbook, but pinging the printer fails, giving "Host Unreachable". The network light on the ethernet socket is lit green, and there is nothing else cable-connected to the network - just a simple cable connection between the netbook ethernet socket and the Network printer (a HP Laserjet 4200n). Ping works fine if I plug the cable into a different machine (a Win XP box) and ping from there, so it's not a cable or IP address problem.
This sounds simple enough and should work, but I'm stumped. Clues, anyone?

configure a server with two network interfaces? This system is physically moved from one network to another every few days (different buildings but connected by a VPN). I'd like to be able to control the IP address of the system depending on which port I plug the network cable into with a static setting. Right now the system will connect to the local network, but any requests to go beyond the subnet get lost. The only way I can get the system to talk outside of its subnet is to comment out the second interface.
/etc/network/interfaces:
auto lo
iface lo inet loopback
auto eth0

We are attempting to convert our entire office over to Linux, however we are experiencing some printing challenges. We have a Sharp-AR-M205 connected to our network that handles the bulk of our regular printing needs. Linux picks this up from the network and installs the driver (Sharp AR-M205 Foomatic/pxlmono (recommended)) without difficulty. We can print from gedit & OpenOffice without difficulties. The difficulty is when printing images, webpages with image content, or PDFs.
Then the printing spool goes into "LPR ..." printing mode and takes between 5-20 minutes to print a single page. This is particularly problematic as each week we put out a simple publication for our organization, designed in Scribus, outputted to PDF and sent to the printer from 200-300 copies. Our workaround has been to leave a workstation as an XP machine to print the PDF each week.

After doing updates a few days ago yumex stopped working. I started getting an error message when I try to run it, "no connected to a network". This is of course not true.
I've looked at yumex.conf and don't see anything wrong, and I downgraded the GTK2 packages from a post indicating a segfault issue with one of those packages.
yum works fine from the command line, so my system is fully updated.
I removed yumex and then reinstalled it with no joy.

I use wicd at my laptop, since networkmanager didn't work well for me.(unable to connect..) However wicd is not connected before fstab probes my nfs shares during boot, so I wold like either to delay the fstab mount command or make sure that the mount command is performed just after that the wireless connection to my home network is up and running. Running mount -a in terminal works well, but I prefer not to run manual commands at every boot. Opensuse 11.2, KDE 4.3
