Using Lucid.
Both "auto eth0" and "Wired connection 1" appear in my network app. See screenshot. I only have one Ethernet card.
is the latter just a rename of the former? I thought so, but the "Wired connection 1" seems to be more reliable than "auto eth0"
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.
Just noticed that auto connection to my wired ethernet is not being established after restarts I'm making. Never recall this in the past. I do get an auto connect when I shutdown and restart. I'm using 10.04 LTS Lucid Lynx.
Also have noticed that nearly every upgrade over the past week or so is calling for restart to complete the upgrade. Can there be any unwanted problems in doing several upgrades over a period of several days before doing the restart? I'd like to think not.
As you can imagine these two issues together are causing some lost time.
If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got
Quote:
Ignoring unknown interface eth0=eth0.
ifconfig tells me
Quote:

so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?
I've noticed that when Linux boots on different machines or with different versions, the network card is assigned to eth0 or to eth1, when there is only one network card. What is the difference and is there any way to tell which one it will be for any machine or version?

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?
Upgraded 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:

I've tried all the various things from dhclient to ifup/ifdown etc etc.
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 have a dell mp1210 xps laptop. I just recently installed installed Ubuntu 9.10 and am very green. With difficulty I managed to install the drivers for the wireless card and now have wireless on the laptop. In order to get the wireless working I had to restart my computer, and once it booted up again the wireless works, but there is no trace of eth0-my wired network device (Broadcom BCM4401-B0) which was working fine before I got the wireless adapter working. Lspci still shows the device as it did when it was functioning, but ifconfig only shows my local loopback and wlan0 (my wireless device). I am not sure how eth0 got deleted, I am wondering if maybe I have to set up some sort of switching between the wired and wireless adapters so they are not both active at the same time. Any suggestions would be really nice, I have been digging through the forums, but I am unsure of what went wrong or what to do about it.

View 4 Replies View RelatedThe situation: The office has a WiFi network on one DSL line, which is used for our VoIP call center, and a wired network for our internal network and the majority of web surfing/traffic . Part of the office must be temperature controlled/monitored - we have a rather nice digital thermometer which is WiFi enabled.I have a Debian Wheezy box with a WiFi card and ethernet connection
What I'm trying to accomplish:Connect wifi enabled thermometer to WiFi network so it can automatically send temp updates (currently I have to do it manually via USB)Have the Wheezy box accept the downloaded file then send it to a back up server in the wired network
Side things that may be useful : Prefer to use wired connection for internet and apt and suchWiFi connection will really just be used for connecting to the thermometer
This [URL] .... topic got me thinking that there might be a way to bring the two networks together, but I don't know if that will wreak havoc on things. I know, the Windows and Mac OS don't like having ethernet and wifi at the same time, might Linux be better for this?
v&n had this to offer in the prior thread [URL] .... which I'll be doing more research on.

View 4 Replies View RelatedI'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.

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.

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?
I recently installed Ubuntu 10.04 on an older PC and I'm having problems with the network card built into the motherboard. When I connect an ethernet cable into the ethernet port I get a solid amber light, and I can't connect to my router, (which is being directly connected). Nothing is shown in Network Connections, but on another PC with the same version of Ubuntu it shows "Auto eth0", and it works just fine connecting with the router.How do I fix this? I'm an Ubuntu noob so I'm not really sure what to do here.
The network card is an Intel 82547EI Gigabit LAN controller, and Intel's website offered a driver available for my kernel version of Linux. However I was typing everything it told me to do in terminal, (which half the time I have no clue what I'm typing actually means), but I ended up getting some errors towards the end of the install process. I'm not sure if I messed something up or the driver just isn't going to work.
I'm hoping there is an easier fix for this, I've been searching the net all night trying to find someone with a similar problem and I haven't found any. I think I have another ethernet card which I might pop in and see if that works....but I figure I'll most likely run into the same problem because I know for sure the motherboards network card works - has on Windows, I just can't get it working in Ubuntu.

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?

View 3 Replies View RelatedI have been trying to connect to the internet with a wired LAN connection for a while now with no luck. Running version 8.04 LTS on a 32-bit desktop. Interestingly, my 64-bit desktop running version 8.04 64-bit automatically connected to the internet with no problems or input from me. Both are connected to the same router.
I figured i'd try and copy the network manager settings from the 64-bit machine to the 32-bit machine, which involved setting an automatic configuration (DHCP}. All went well except no DNS server address showed up on the 32-bit system, despite there being one on the 64-bit system. Trying to run Firefox like this results in the 'page load error' page coming up immediately.
I then manually added the DNS server address from the 64-bit system to the 32-bit system, and all that did was prolong the time it takes for the 'page load error' page to appear.
I have two PCs one has Windows XP the other has Ubuntu 9.10 on it, the Windows PC has no problems getting on the Internet (I'm posting this with it) and getting an IP address from the wired router. The wired router I have is ONLY wired it does not have wireless at all, it is currently setup to hand out IP addresses between 192.168.1.2 and 192.168.1.254.
The Ubunutu 9.10 PC worked great last night surfed all over the place for hours, then finally shut it down last night when I went to bed, shut down appeared to be normal like it always does when it shuts down, then this morning when I booted it up it gave error: "WIRED NETWORK - disconnected you are now offline".
I just installed ubuntu 8.10 on my pc. Before was XP installed. I formatted the system and installed ubuntu. Installation was successful. Problem is that I cant connect to network. My network card: realtek 8139 ethernet card

I am using ubuntu in my new office, and I can't get the network working. The "official" OS installed was a Windows, and it has a special "dial-up" app for the LAN connection (not wireless). My network admin is apparently not helpful, since he actually knows nothing about the internals for the "dial-up" app (he did not even ever heard of TTLS, PEAP, MD5, etc), and claimed that no OS except for Windows can work...
Well, I have tested various configurations with my Mac laptop, and apparently the LAN connection requires 802.1X authentication, and it's using a very weird combination "TTLS+PEAP+MD5" (if I check these options in Mac OS X, the connection works). However, in NetworkManager, I can't select both TTLS and PEAP, and moreover, TTLS does not work with MD5. So, is there anything I could try?
Fresh install of UbuntuStudio 10.04. This is really bizarre.
I can't seem to connect to the wired connection mainly because there is no connections tab (pic attached).
