Fedora Networking :: WLAN Disconnected - Network Configuration Messed Up
Jul 20, 2009
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`m relatively new to Linux and Ubuntu.Now I have been playing around, editing the settings files for the networks cards, and now I have messed things a bit up.Any way to delete all settings, and make Ubuntu autodetect my hardware again?
How to enable wifi? I downloaded and installed Debian 6.00 and as I couldn't get online with my Tenda USB Wireless Adapter. I downloaded Debian 6.00 again, this time the CD Net Install version with Firmware included. However, the added firmware version of Debian does not find my wireless either. My wireless adopter is shown as Bus 001 Device 003: ID 148f:3072 Ralink Technology, Corp. RT3072 Wireless Adapter. There is a Network Icon in the Panel which when clicked shows "Create New Wireless Network". I have put in my ISP related network and my password and rebooted, but all I get is the message on my desktop:
"The Network Connection has been disconnected."
That isn't very polite, is it? Who has disconnected it and why remains a mystery to everyone except the culprit(s). I think I must have missed a basic step in the Wifi Enabling process. I checked the Use Permissions and everything is fine there, as User I have permissions to use modems and do networking and so forth. Also I should like to try "modprobe" but I see the package isn't in Synaptic Package Manager.
I am newbie to linux, I am dealing with Fedora core 13. I have already succeedded in building an ad hoc network and a WLAN network. My next step is to get some networking statistics such delay, throughput, etc. So, I need traffic to flow through the network for both multimedia traffic and bulk data traffic. How to send files between nodes on the network (I found commands ftp, rcp but do not know whether they are the correct choice for this). ID their any application to perform this?
Also, I want to perform some video streaming between two nodes to study the behavior of real time data transfer. Is thier any application to perform this?
Since a recent update on Stretch, I have been unable to use the network-manager to connect to my home wireless network on my laptop. It was working fine before. I did not change any settings on the WLAN router. I can still connect to other wireless networks at work and university, just not this particular one at home. All other non-Debian devices in my household are still able to connect just fine.While figuring this out, I have tried connecting manualy with ifup but I don't really know how that works. Right now there is only the loopback entry in /etc/network/interfaces.
Below is the output of syslog, when gnomes network-manager is trying to connect, but fails. Code: Select allJul 19 20:01:57 debian NetworkManager: <info> (wlan0): Activation: starting connection 'Affenbande' Jul 19 20:01:57 debian NetworkManager: <info> (wlan0): Activation: Stage 1 of 5 (Device Prepare) scheduled...

Everything worked fine until I downloaded some Ubuntu upgrades. Now, every time I try to connect to internet via network manager it says: " Network: Disconnected - you are now offline". so what to do...
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 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'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.
Ive installed 10.04 on my laptop and notebook. It works perfectly on laptop. On notebook the problem is it finds no Wireless network and just says disconnected. I have no idea how to connect it, I tried reinstalling Ubuntu but no luck. I tried looking it up on internet but no luck in finding help. its an MSI U130. The wireless is defently turned on.
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 $interface inet 0 exit_with_hooks 2 "$@" fi
i used to download files using transmission bit torrent client. I download the torrent and once the download starts i will leave the system and check only after 4 or 5 hours later.But when i check the system again, the network connections were automatically disconnected.The download is getting stopped naturally. why my wired network connection is getting disconnected automatically if the system is idle?(ubuntu 10.10)
I have successfully installed xubuntu on my 2nd partition of hard disk through unetbootin. everything works fine except wireless network. my ethernet works good, i am tethering through my android mobile no problem....just wireless says disconnected where as it is enabled. As far I know its sould scan all the available wireless AP near me and it should appear below wireless networks, and from there I should be able to select the AP which I want to connct...
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.
There is no wlan0 interface when trying to run FRITZ!WLAN USB Stick N 2.4 on OpenSuSE 11.2, though it works fine on Fedora 11 and Mandriva Spring 2009.1. All 64bit. Contrary to Fedora and Mandriva, there is no need to compile the compat-wireless module ar9170usb for OpenSuSE 11.2 because the kernel is very recent and includes this driver. Kernel: 22.214.171.124-0.1-desktop The /var/log/messages gives this after I put the stick in the PC. At first it is seen as a mass storage device:

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 recently installed Fedora 11 on my machine, the configuration of which is: Intel Core i7 920 CPU, 3 GB DDR3 SDRAM, nVidia GTX295 Graphics Card. I initially used the default kmod-nvidia driver, but with a yum update, somehow a non-PAE kernel got installed and the kmod-nvidia driver did not get installed with it during the update for some reason. So I uninstalled the PAE kernel and associated kmod drivers, and downloaded the nVidia driver from the nVidia website. It ran just fine for a few days, and then all of a sudden, after a reboot, the X Server crashed and I had to log into the text mode, run
Code: setup and do the default X configuration. Then, I re-installed kmod-nvidia, with no luck. Sorry for being so vague about this, but I finally managed to get the CUDA driver (I need to use CUDA for my project work) to work (downloaded from [URL]). But after one reboot, the same problem resurfaced.
Now, I am in X Windows with a default 800x600 configuration using a generic visa driver, on a 23" monitor I have been rebooting my computer all morning and trying various things to get the driver to work again. I would be happy to furnish any details about the installed packages I have. For now, here is some information.
At first my internet was really choppy just using the default network manager, but I switched the kwlan and that was going pretty well, til I had to reboot and it decided to not work anymore. Now my kernel has no network manager, and I just need some guidance.
I tried downloading the original network manager deb packages from the ubuntu archives, but I couldn't get the core application to run (though I could get the GNOME applet) even wtih chmod I didn't have permission to do anything with it.
I have just installed Ubuntu 10.10 64bit on my laptop Toshiba Satellite A665-S6065 and I can connect to wired network but I can not connect to wireless network "Network Connections disconnected". Im following this post http://ubuntuforums.org/showthread.php?p=6183681

i have Fedora 14 OS, i installed an openvpn, & i got a problem with it, which i get disconnected automatically after successfully logined, one of the members here (ZeroSignal ) told me to comment any lines in /etc/openvpn/anyname.conf file, which contain the word update-resolf.conf, & my problem get solved, but now after i logined to the openvpn network & after half an hour (or less sometimes) i got disconnected from the network.
My friend has 2 pcs, one connected to the internet and the other one used to connect (when he had windows installed) to the internet through the first one using internet sharing, now i installed ubuntu on both and the network between them has been created but it wont connect, the internet icons just animates for like a minute then says "wired internet disconnected" in other words it failed to connect.
Cannot activate network device eth0!"device eth0 does not seem to be present, delaying initialization".i cannot find my network card while i set up network configuration Now I use dual boot window 7 and fedora 9,I cannot find my network card in select network adapter while network configuration ,i have a network card Atheros AR8132 PCI-E fast Ethernet controller NDIS(620)and for wired in Accer laptop .
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.
the default for /etc/network/interfaces? I believe I screwed it it up because I can detect my wireless, it just won't allow me to connect to it. The settings in the /etc/network/interfaces are all messed up. I'm running Ubuntu 9.10.
I bought an USB-WLAN stick, which does not recognize any network. A Ralink 802.11 bg WLAN Stick works fine, but the Ralink 802.11 n WLAN Stick does not work unfortunately. Both get recognized by the nm-applet of network manager but only the first one recognizes my network and is able to connect to it.
recently I risked a look to the Linux world and I'm happy so far, but now I've got a Problem, I'm unable to solve by myself. I installed Mint (Julia) on my old Laptop to test Linux. The Laptop has a very old PCMCIA WLAN Card with a Realtek rtl8180 chipset. Everything seems to run perfectly so far with one exception: the WLAN doesn't find any Network to connect although the card and the driver seem to be installed correctly.
Here some code from the terminal:
