Ubuntu Networking :: Wired Network Card Not Working - No "eth0"?
May 27, 2010
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.

I have no internet connection. I am running dual boot windows XP and ubuntu. The card works fine in windows, but doesn't work at all in Ubuntu. This is the card I am using Realtek rtl8139/810x Family Fast Ethernet Nic. I am using Ubuntu 8.10, codename intrepid. I hate windows because of the viruses I contract everyday, so I decided to use Ubuntu, but this does no good without networking. so I can get online. What I do now? It is an onboard LAN card, cable is plugged in a green light is on, ubuntu just doesn't recognize it.

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.

I have a 64 bit install of Ubuntu 10.04, I was surfing up to 11:30pm EST last night, shut down for the night, upon reboot am unable to connect to the internet or my local network. Ubuntu seems to think that I have no ethernet cables connected.My networking is controlled by my motherboard (Gigabyte P55A-UD4P) and the problem is not on my cable modems side. The modem has multiple wired jacks, all of them are unresponsive with my Ubuntu PC while my roommate can connect to all of them with his Windows 7 PC. Both network cables (the one connecting to his box and the one connecting to mine) are interchangeable: They both work on his and neither on mine, so there is no broken cable.I've followed the troubleshooting in other posts, here are some commonly requested diagnostics:
ifconfig -a
Code:
eth0 Link encap:Ethernet HWaddr 6c:f0:49:53:1f:c0

I am facing a problem with the management of my network card after installing Ubuntu 11.04 32-bit Desktop edition.
There are two Network Cards and one USB adapter which I'd like to drive:
- Ethernet controller Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02)
- Ethernet controller Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
- Realtek Semiconductor Corp. RTL8187 Wireless Adapter
Actually I need the wireless adapter to connect to the AP, so both of the ethernet card should be disabled. Infact, when I try to access to the AP I must disable the eth0 card by using (sudo ifconfig eth0 down), otherwise the route assigns the default gw (192.168.1.1) to the eth0 device and the network is useless.

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?

Would it be possible to insert another wired network card into the router-connected computer, share the internet connection and be able to transfer files between the two?

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.

I just installed Lucid Lynx on my Dell Vostro 1000 laptop. The problem I'm having is that my wired network card has died on me prior to installation. I'm having the hardest time finding the required files to make my Broadcom BCM4311 wireless card work without being able to download any packages from the web. If anyone knows which files I need and which order I should use to install them that would be great.

I recently upgraded to 10.04 and now my wired network no longer works. I am unsure if it worked at all since the upgrade as that computer is rarely used, but it was definitely working prior to the upgrade. It is some sort of Realtec card, I believe. Does anyone have any suggestions? I'm running 32 bit 10.04 on a 2 GHz P4.

I use Ubuntu 10.04. Last night, I installed the most recent updates for this istribution, and before I shut off my laptop, my internet was working smoothly. However, today my Internet connection is behaving very strange. When I try to connect to the internet, my browser times out or cannot establish a connection. I'm able to connect to low-input sites like Google search, but I cannot connect to sites like Facebook, Wikipedia, or even the Ubuntu forums (I'm currently using a friend's laptop to post this). Pidgin and Skype work without a problem, as well as Transmission. I primarily use Firefox, but I also tried Chrome, Opera, and Epiphany; none of them worked. Oddly enough, my update manager also cannot connect to the Internet to retrieve updates.
I have restarted my router, but it still works properly, as it is running fine on my friend's laptop. I have tried 'no proxy' in Firefox, but it did not help. I also disabled IPv6 in etc/sysctl.conf by adding the code:
#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
[code]....

My wired network is not working! This is the result of ifconfig -a:
Code:

I'm not a total newbie, but run into some strange problems with my installation of Lucid.Everything was working fine yesterday. I shut down the laptop and powered it up this morning and had problems with network. I have two NICs (wired and wireless). Both are set to pick up IP settings from DHCP and both do, however when using wired network I can't communicate with outside world - can't even ping the default gateway (but pinging 127.0.0.1 or IP address of the NIC no problem, so stack should be OK).When on the wireless network everything works fine (otherwise I would struggle to write this post ).What is very weird though is that I have a VMWare Player installed and using Windows VM on wired network works just great!
I noticed that when you're persistent it happens that you can ping but huge chunks of traffic are lost (e.g. packet 1-10 would pass, 11-40 would be lost, 41-59 would pass and so on).I restarted Ubuntu, tried shutting down interfaces, disabling networking and nothing helped. I don't recall performing any changes (at least that I would be aware of).Can anyone suggest something?BTW. This is not DNS issue as both IP addresses and FQDNs do not work. When I refer to using a given network (wired or wireless) the other one is down with ifconfig command...

I'm new to Ubuntu - I've decided to give Ubuntu Studio a go as an alternative to Windows. However, after installing it, neither of my network cards work. I have a Intel Pro Wireless 3945ABG wireless card, and a Broadcom Netlink Gigabit Wired card. Neither work, And I'm not sure how to. I've tried searching, and have come up with the .tgz file here, but I have no idea what to do with it I'm concentrating on the wireless card for the moment, seeing as that will be the main one I use.

My desktop computer has another Linux distro on it. Wired networking was working fine. I wanted to try Ubuntu 10.10 so I installed it on a spare USB HDD. After install, networking still worked on both distros.
I moved the USB HDD to my win7 laptop and Ubuntu 10.10 booted fine. Once booted, Ubuntu asked to configure wireless on the laptop. I tried to do this but it did not work.
Therefore, I moved the USB HHD back to the desktop and booted. Now the wired network does not work from either Ubuntu or other distro (fedora 14). And to top it all off, the wired network will not work even from the Ubuntu live CD.
I have checked all connections, switches & cat5 cables to my desktop computer. I can still access the network and internet from my laptop (in win7) so I do not believe it is an infrastructure issue. I can confirm that everything works from the cable out of the back of the desktop through to the internet.
Here is the output from the usual troubleshooting commands in Ubuntu 10.10 code...

I did a fresh install of Ubuntu 10.10, coming from 10.04 and the wired network connection sometimes works, and sometimes doesn't. Right now I manually removed current network from System-->Preferences--> network connections, define a new one, and reboot. This usually fixes, although I've had to do this two times in the past.
Other general info
Ubuntu 10.10 64bit, EVGA P55 motherboard, on board either net.

I had an Ubuntu Server 32 bit installation and everything was working fine. Now that I installed Ubuntu Server 64bit on a new drive in the same machine, the ethernet card is not working!! This is insane cause when I put the hard disk with the 32bit installation back and booting from it, the ethernet card is working without any problems but in the 64bits installation it is not shown at all using "ifconfig -a"
lspci output:
Quote:
02:00.0 Ethernet controller: Atheros Communications AR8151 v1.0 Gigabit Ethernet (rev c0)
How can I check which module is being loaded in the 32bits installation to try to load it manually in the 64 bits installation?

I'm running Ubuntu 10.04 Server. I can't get my Wireless Card & Wired Card to work at the same time. My interfaces file is incorrect, when I comment out 1 of the interfaces the other works. I have attached my interfaces file.

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?

I recently installed Xubuntu on my old P3 laptop (Compaq Armada E500 if anyone is familiar). The laptop is a bit old, so both wired and wireless networking is done via PCMCIA cards. I have 2 cards installed, one for each purpose. I can't find the dongle for the wired card right now, so I am trying to use the wireless card. I am able to find the network I want to connect to, and type in the password since the network is secured. It tries to connect but then pops up again asking for the password (I know it is correct). Is this card supported by linux/compatible? I tried finding drivers online but the sites that had drivers were down.

Just installed Fedora 14 from the Live CD i686 on my Dell Inspiron 1521. I can't connect to the SpeedTouch 585 on either wireless broadcom card or the wired Ethernet card.
I can connect to it from the same Laptop on the Vista which is on dual boot on the same laptop.
Further confusing is that I ran Fedora 14 and connected to another SpeedTouch today.
Already checked the Channel on the wireless nic and it's on the same one as the SpeedTouch.

I have BroadCom BCM4318 802.11B/G Wireless Card. When I first started Ubuntu a week ago it didn't work, but I fixed it after a day or two of googling it. However I made a mistake and uninstalled the Network Manager. I then reinstalled Ubuntu, but it wouldn't load the card again. I activated the driver, and restarted the computer, but then, since It was connected via Ethernet, it wouldn't reconize the Ethernet connection, but the wireless card it did, but wouldn't find a network that is supported.

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?

I'm running slackware 12.2 and I have yet to get the b44 kernel driver working with 2.6.27.31 (custom build, b44 compiled in). Does it require a firmware cutter (ex. b43-fwcutter)? Does it work in later kernel versions out-of-the-box?
On a second note, if it is better supported in later kernels, would it be problematic to upgrade kernels (for instance, anything other than just building the new kernel via instructions in the Slackbook)?
I have searched many times but just have come across "it should work" which it doesn't, at least here...

I have setup a dual boot machine which has OS of Windows Vista (32 Bit) / RHEL 5. The LAN Card details are - Atheros L2 Fast Ethernet 10/100 Base T - Controller. The said Network Card works fine with the ADSL Connection in Windows OS, but does not seem to initialise in Linux. When I run "ifconfig" in terminal window it gives away the prompt - "eth0 no such device exists".Although it shoes the loopback adapter (lo) device working fine. I forgot to mention over here, I have just started with Linux. So, I request "the" Linux Gurus to help me out with this one.

Yesterday I installed a RaLink RT2800 802.11n PCI on my squeeze system. Now I have a connection to Internet but I can not connect other systems in my home network. An ssh-try to a system in my home network results in: ssh: connect to host xxx.xxx.xxx.xxx port 22: No route to host If I use my eth0, I do not have connection to Internet, but I can connect other systems in my home network.
