Networking :: Make The "Wired Network Disconnected" Graphic Stop Appearing?
May 15, 2011
I am running Ubuntu 10.10 on a brand new laptop, an install done by the company I ordered the notebook from. I have some limited experience with Linux and Ubuntu especially.I know that I'm not connected to a wired network. I haven't so much as plugged in a network cable, but the graphic appears erratically on the right hand side of the screen like I am connecting, then disconnecting. I've tried disabling the eth0 connection altogether, but no dice. I can't figure out how to make it stop.

I'm having network problems and I have no idea how to fix it. At first, my internet connection was suffering on all computers on my network (Mac, Windows and Ubuntu 11,04). So, I disconnected my cable-modem and then reconnected. Nothing.... So, I rebooted my Windows machine and the internet came back on that computer.
I then went to my Ubuntu computer and clicked on "auto eth0" (per the way I interpreted instructions from the internet). The symbol turned from the "two arrows" to what looks like a wireless, looking for a signal. I thought that maybe I should just reboot, as I did with Windows. However, when I did reboot, that same wireless symbol was there, then a message came up saying:
Code:
Wired Network: You are now disconnected
I can't seem to get my internet connection back on my Ubuntu computer, though it is working on every other computer on my network.

I installed xubunto 10.4 on my pc the other day and every thing was working fine and then the next day my wired network card went down. So I restarted it and it say Wired Network Disconnected. I tried doing sudo ifconfig eht0 up to try and bring the card back online but nothing happens. I also tried reinstalling xubuntu on my computer. Again my internet works then starts freezing up so I restart it and my ethernet card goes down again. I have tried also plugging it into the second ether net port on my computer but that does not seem to work. Also I went into my dhclient-script and went to the bottom to look at my network card stuff.
It reads
#Changed from 'ifconfig $interface inet 0 down' - see Debian bug #144666 ifconfig $interface inet 0
exit_with_hooks 2 "$@"

I just installed Ubuntu 10.04, complete noob, but I can't connect to the internet. I connect the ethernet cable, select auto ethernet and the icon animates for about 30 seconds. But then I get a notification "Wired network Disconnected - you are now offline".
Don't know what other information I should provide. I tried a few things from different posts like editing the dhcpclient.config but don't really know what I'm doing and none of these worked anyways. I'm not even sure if they were solutions to a similar problem! I'm using the same connection on my Mac OS 10.4.11 (different machine) and I have no problems. Could I use these same settiings in Ubuntu? I don't know what the different fields represent or what I should input in manual settings.

I'm stuck after a clean install of FC14 on an old Everex StepNote (Doing this for a friend). I tried Ubuntu on it first (because it's so easy) but had horrible stability issues and terminal commands wouldn't respond - however Ubuntu detected and ran the eth0 port just fine. FC14 detects my ethernet NIC, but it won't work.
Here are my details.
lspci outputs this for my NIC:
00:12:0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 7c)
Here is what I have tried so far - with no luck:
- I have toggled the networking switch on the laptop and had no luck.
- Downloaded Via's VT6102 drivers for Fedora Core, but they don't support kernel 2.6.35.*
- Run ifconfig to manually assign an IP address - which it DID take and did route add default gw as well.
- Did a ifconfig eth0 down and up as well.
After all that, I still have a "disconnected" wired connection (and yes, I did check the cable - it works just fine in my personal machine.

Is there a way to stop net access if a vpn is disconnected? I will be using a vpn for all my internet access on a specific machine, but if the connection is dropped, I don't want that box to continue to have access to the net until the vpn is re-established.

I have Debian Squeeze AMD64 bit release. It finds my wired ethernet connection and ues itfine, although nothing shows up in the top right corner under the networking icon.
When I plug my mobile phone in (HTC S620) it always uses this as the main internet connection and then even if disconnected wont use my wired connection until I reboot.
Is there a way to stop it doing this or at least have my wired connction as an option so I can just click to reconnect to my ethernet connection?

Ubuntu 9.10. Everything works fine until yesterday when I cannot connect to network. My lan card is Realtek PCI and is present on system (i can read mac address and all settings). In connection manager I was try to set everything manually (IP, netmask, gateway and DNS) or leave automatic - without success. I am connected to router. I don't want to feed "log-hungry" people because how to resolve ubuntu lan problem can help me (not someone who will want to try). I cannot connect manually because there is no option when I click on network icon (I can just uncheck connection, but that's all). I can't even access to my router (from computer with Ubuntu, because I can access from another computer). All logs shows lan card proper. Windows XP on the same computer booted from another HDD works fine.

My wired LAN keeps dropping randomly, average of every 30-60 minutes. Fresh install of 10.10 from iso, Been installed for about 4 days now, just performed system update today, no change.
My router actually completely resets itself. You can watch the lights power off and recycle doing their POST. Absolutely no problems in windows 7 dual boot configuration.
I am no downloading anything, not streaming, not doing anything actually. My computer is completely idle (save for BOINC) and all of a sudden my phone loses the wireless connection which lets me know that my router just reset.
Ubuntu is actually doing this, my wireless stays up indefinitely in windows. Once the router resets, it does automatically reconnect without a PC reboot, but why is it resetting my router?
If you need the bootscript, already posted here: http://ubuntuforums.org/showthread.php?t=1651262

The title message appears when I log in. Neither wired nor wireless network adapters show in ifconfig output. Network manager shows a simple networking disabled greyed out message. Both adapters work in live cd boot. Everything was working properly before; I'm not sure what happened.

I'm running Ubuntu Karmic Server with Xfce desktop, the problem is the network manager, it says it is disconnected, even though I am connected to my network and getting an internet connection. It wouldn't normally bother me, but I'm trying to setup a VPN using the network-manager-openvpn plugin. I put in the required details for the VPN connection, but as soon as I tick the "apply to all users" box, the information is lost. The information will remain if I don't tick that box, but it will not connect. when I try to select the VPN connection I just setup, nothing happens.
I've tried the exact same configuration on another desktop, running Ubuntu Karmic with Gnome desktop, the network manager works fine, my ethernet connection is showing as connected, and I can connect to the VPN no problem, the problem lies with the network manager in Xfce. Is there anyway I can get it to show as connected? it wont allow me to connect to the VPN otherwise, it's silly, because that adapter has a full working network connection.

Recently, I had the courage of installing Fedora 11 on my laptop while risking of trashing my Windows XP. Fortunately, the installation went fine and windows and fedora seems to be working together. But I needed to reinstall Fedora because I didn't do the partitioning right. After that the problem arises. I couldn't connect to the wlan. The first installation it was working fine. Now I can't. I select the network, enter the password and then it just says "Disconnected" or something like that then nothing else happens. So I had to reinstall it again thinking I did something wrong on the installation. But still it wasn't working. But it seems to be working when I boot from the live cd. I must have messed up my network configuration.

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.)

I use Pidgin as my IRC client. I set it to remember my passwords for the #linuxjournal and #ubuntu channels. As you can see in the picture, there is a tab titled Frigg. I don't know if Frigg is a user or bot or channel! How do I prevent it from appearing every time I start Pidgin? I closed it before but then it keeps coming back when I restart Pidgin!

running Fedora 15 on a Dell Inspiron 1521. When I first installed Fedora on this laptop, I was unable to connect to a wireless network because I did not have the firmware installed, so being a good little enthusiastic new user of Fedora, I set out on a quest to locate the proper firmware. I had success on that front, however, in the process of installing it, the option to connect to any wireless network disappeared. It isn't that there is no wireless network in range, rather, the entire wireless option itself has vanished.

I have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?

After some system updates, I now have the Grub menu appearing every time I boot my computer. Is there any way to disable it, or make it automatically boot whichever entry is selected by default? I only have one operating system installed, so there's not much of a point to having to press enter every time my computer starts up.

I am relatively new to linux and am running into a problem. I just got a new laptop and need to configure/install it's wireless driver but am getting an error when running "make". The error is: make[1]: Entering directory `/lib/modules/2.6.37.1-1.2-desktop/build' make[1]: *** No rule to make target `modules'. Stop.
I have scoured these forums and know that others have the same issue (when configuring other drivers/programs). I am sorry if this post is redundant. It sounds like the Makefile is pointing to the wrong directory. I am using opensuse 11.4, have make and gcc installed. My kernel is linux-2.6.37.1-1.2 (I just re-installed the desktop kernel to make sure it was up to date). The driver I am trying to install is located here: AUR (en) - rtl8192ce.
Another forum suggests pointing somewhere in the /usr/src/linux-2.6.37.1-1.2 directory instead. Is this correct? Should I be pointing to a folder within this? I am not a programmer but any description about what I am actually putting in this directory and why would be awesome (so I can learn a bit more). Or just helping me solve the problem would be great too.

Got a used Lenovo Thinkpad r61i and put Ubuntu 9.10 on it. Every time I turn it on it prompts me to give it a password for someone else's internet. This a password I do not know and I use an ethernet cable for internet so it's really annoying. Any way to make it stop?

I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?

Issue: Using Fedora-14-x86_64-Live-Desktop.iso, I created a live usb and tried it on Dell M6400. I can boot into F14, see the internal hard-drive and other usb drives -- but F14 will not go on the network -- neither wired or wl networks.
I am not sure what additional information I need to provide to help resolve this issue. Perhaps some background info would help?: I am trying to move from XP to linux on the M6400. The latest Ubuntu live CD would not boot, the latest CentOS live CD could not find the internal drive; I got best results with the latest Fedora (and I am more comfortable with the F14 gnome interface than the F14 KDE, the Ubuntu, and the CentOS interfaces). I do not know how to investigate the inability of F14 to detect the ethernet cabled network. I was unsuccessful in my attempts to get the wireless to work: "lspci -nn" shows BCM4322 802.11a/b/g/n 14e4:4326 (rev01). I read [URL]../docs/linux_sta/README.txt and used what I learned in my attempts. Installing broadcom-wl-5.60.48.36-1.fc13.noarch.rpm, kmod-wl-2.6.35.6-48.fc14.x86_64-5.60.48.36-2.fc14.2.x86_64.rpm, and kmod-wl-5.60.48.36-2.fc14.2.x86_64.rpm (found at rpmfusion) did not help. I tried to build and install the sources from http://www.broadcom.com/support/802.11/linux_sta.php; the machines I had for building were 2.6.28-18-generic Ubuntu, fc5, and rhel5 -- attempts with these builds failed too.

entries for connecting to broadband. Was OK with ubuntu 8.04 which had boxes for DNS server, etc. The 10.04 asks for MAC address (?) and there is a space for "DHCP client ID". I don't understand these terms. how I may proceed, especially exact syntax for any command line work. I am in Chennai/Madras, and have a BSNL wired broadband connection to my Dell laptop.
