Ubuntu Networking :: Getting No Ethernet Internet?
Sep 1, 2011
In 10.04 I get the following error in the log while connecting to ethernet:
Code:

I have a server with two ethernet ports. I configured eth0 to be static, set at 10.1.10.148. I plugged in another router into the other ethernet port in order to configure that router. I configured eth1 to use dhcp. Using /etc/network/interfaces rather than gnome network manager. When I did this, I lost internet connectivity (internet routes through eth0 of course)
- Why did I lose internet connectivity?
In order to recover internet activity, I had to disconnect the new router on eth1 of course, and do sudo ifdown eth1. That wasn't enough however. After rebooting numerous times and pulling out my hair, I finally tried configuring eth0 as dhcp, rather than static, and this fixed the problem.
- Why didn't sudo ifdown eth1 solve the problem? What information was saved between reboots that somehow remembered that I plugged in the new router? Because my thinking was if /etc/network/interfaces was identical, and the network topology was identical, after a reboot everything should be restored, but it wasn't.
I recently moved to a student dorm in my university (RWTH Aachen) and I have an ethernet connection from my room. The thing is that I can't connect to the internet, I don't get any IP through DHCP. I tried using wicd instead of network-manager, and doing it manually with dhclient. None of those worked (actually I don't know much about how networking works so maybe I didn't do it well with dhclient). The weird thing is that Windows 7 gets the IP instantly and I can connect to the internet from windows. But I don't know why Ubuntu refuses to get an IP. Info from lshw, lspci:
I am basically wanting to use my Ubuntu 10.10 computer as a router. Note: Before you say just get a router please note that I am poor/cheap. I have two ethernet connections and one wireless connection on my netbook. I want to share the internet connection that is going into one of the ethernet cards through the other ethernet card and the wireless card.
DSL-->1sr Eth --> 2nd Eth (currently works) DSL-->1sr Eth --> Wireless Card (Adhoc) <--(connects with limited connectivity AKA no internet)
The 2nd Ethernet card already has working internet, but when I connect to the Wireless card (through an Adhoc network), it cannot get an IP (I believe).
My laptop was on windows xp and when I installed ubuntu linux my NIC Card driver was gone (I think) and now I can't connect to the internet using an ethernet. I have the driver on the desktop of my Linux laptop but I don't know how to add it using terminal or any other options.
just recently I made the move back to Ubuntu from Windows. Upon re-installing I noticed a problem with me connecting to the internet. Previously on Windows I had updated my Ethernet Adapter driver, upon installing I would have to disable and re-enable the device to let my computer have access to the internet. My problem here is how would I go about fixing this on Ubuntu so I can have internet access on Ubuntu
I am running Ubuntu 11.04 and i am curious to if there is a way to share my established wireless connection through my Ethernet port.. I know it was possible in Windows by going to adapters and bridging the wireless, and Ethernet adapters. how to make this work in Ubuntu?
I am using Ubuntu Server version 10.4, and am trying to connect to the internet via an ethernet cable. This may and probably is incredibly simple, however, I could not find anything that pertains to it.
After some fiddling around, I have come to the conclusion my current wifi access point hates my other computer's Broadcom chip or the drivers thereof. So, my current idea is as follows. I would like to use my netbook to connect to the wireless network, and then connect my other computer to it through ethernet. My netbook is dual boot XP and Ubuntu (think Ubuntu is a version behind) and I would be fine to set up this sharing in either and just leave it on as a repeater station. My other computer is dual boot XP and Fedora and I would prefer this work to allow me to have network in both. I have a straight-through cable and have verified that my network card supports the automatic crossing over behavior.
I tryed to get network work like this share internet from wifi (wlan0) to ethernet (eth0).So the internet connection comes from the wifi and we share to other computer via ethernet[URL]But when I restarted my pc then it dont work and network says "wired network device not managed" How can I get it work aigan ?[URL]Now I have anohter problem when I connect autoeth then the wireless network dosent work anymore, I have to disconnect eth0 to have wirelles network working. how can I manage to get the bowh to work?
I tried to setup sharing to connect Ethernet and wireless. I want Ethernet connected to desktop A, and wireless connected to another laptop(B), with my laptop acting as an AP. I set the network settings in Firestarter: Internet for wireless, local network for Ethernet. I want to share Internet from laptop B over the network. Internet won't work from my laptop since it seems to use the wrong interface.(Since the desktop is sharing Internet, although not on Internet usually when connected via Ethernet. And of course DNS/Gateway IPs aren't set for wlan0 since it's acting as an AP.) SMB wouldn't work for desktop A and laptop B: laptop B could detect desktop, but reports error "Path not found".
I changed to a 4 port ethernet router (D-Link DSL-2542B Adsl2+)with intention to share Internet access with my brother (he's on Vista).Initially it all went well,but 3 days ago there were connection problems occured on the part of the ISP. Without realized the problem,I had reset the router.This morning I've been informed by the ISP that the connection has been re-established.So,I accessed the Internet via the 4 port router but failed to do so (server not found).Suspecting that the problem was from the 4 port router,I reverted to my old Adsl router (DSL-520B single port) and without any problem I managed to access the Internet back.I really need help to configure back the 4 port ethernet router to its initial state.
Just recently got a new rig, and was wondering, is there a way to share internet via a switch. I understand the problems with switches is that they dont assign IPs like routers do, but if my ubuntu machine worked like a router by assigning IPs, could it work? Current setup is as such. I have one ubuntu machine with 1 ethernet port (this shall be the main preferably) 1 mac with a single ethernet port 1 modem with a single ethernet port that cannot assign more than one IP address. And a 5 port switch. Would it be possible to place the modem into the switch, get the ubuntu machine to receive the IP address, and broadcast all other address' to everyone else via the same switch and ethernet cable?
I am using ubuntu (11.04) here, when i connect Bsnl broadband link(wired connection). Internet is connect automatically But unable to instal, upgrad and access Internet pages ..
I have a wireless Internet modem (USB) and a LAN Ethernet connection. I can only pick 1 of them to connect to (by disconnecting the other). How can I connect to both at the same time?
I installed Fedora today, and I automatically had internet connection, I never had do configure anything myself. Then, I was playing around with VPN for a good while (trying to set up the VPN connection to my University), and now, I suddenly lost my connection to the internet!
But only Fedora can't connect anymore, the Windows PC has connection as well as my Mac OS X (I dualboot Linux on my MacBook). The Ethernet connection works as well, when I unplug the cable, Fedora gives me a message, but I just don't get into the internet!
Does anyone have an ides what I have to do? I don't know anything about network connections and I'm new to Linux...
I already restarted the Computer, but that didn't work, and Google didn't really held either.
I have just installed ubuntu 10.04 using the wubi installer to dual-boot my machine. Under ubuntu, I am not able to connect to the internet or my router. Everything works fine under windows. I have tried to find relevant information in the forums, but nothing seems to work for me. I have tried disabling ipv6, setting a static ip, but no go. ifconfig shows no IP, dhclient results in no DHCP offers and pinging my router's IP results in Network is Unreachable.
My laptop was working fine on wireless till the userinterface changed and it defaulted to ethernet and now it won't let me go back on wireless How do i disable ethernet?
I just built my first pc, installed ubuntu 9.10 and tried connecting to the net through my ethernet cable and all that happens is it says cannot find server. Do I need to install network settings & if so what & where,or should it automatically detect them? As this is my first build I am a novice but am willing to listen & learn.
I have installed ubuntu 10.10 on a hand me down computer and put a new network card in it (planet ENW 9503) i have managed to locate a linux driver for it from planet.com but i have no idea how to get it to work i have tried a few things it says to do in terminal. everything i have looked up needs an internet connection?

I have opensuse 11.0 on a PC with Broadcom NetXtreme BCM 755 ethernet adapter. I am not able to connect to the internet. what could be the problems. how to solve it?
My WiFi can connect to internet without any problem, until I plug my ethernet cable ...then I lose internet.
So the question is : how do I configure my ip/dns and stuff to still have internet when I'm plugged by cable at the same time! it was working on windows ;-)
Ever need to provide access to multiple PC's and did not have a router only a hub. Maybe this isn't original thinking, but then again maybe you didn't think of doing it this way (which i am sure there are many ways to do it) So I have 2 Ubuntu Servers, 1 Windows Box and a Hub - All 3 with internet access off of single ip and single Ethernet port.
While searching for a backup method today I came across Clonezilla. I was wondering if this was the right thing for me and since I needed to backup my roommates PC for a reformat and install of Windows I decided I would give it a try, but only if it would work. I didn't want the hassle of going into the main part of the house and finding out what cord was what as there is a cable modem connected into a switch (4 static IP's with internet) and one port of the switch hooked to a router) Anyways, didn't work he was on the router I was on the switch)
But this got me thinking. When I setup my server to do this, during one of the setup scripts it said it was setting up Internet access for client machines and that it was assigning them IP addresses threw a DHCP server that it had installed.
So, I dug up the hub connected the internet cable to hub up link and Server 1 on port 1 Server 2 on port 2 and Windows on port 3 The main server gets the internet provided IP address and routes it to the hub via a virtual interface. Server 2 is configured for DHCP and the windows box, It was set to get info automatically but it didn't fill the DNS info so I had to manually do that (just a heads up) I decided to use OpenDNS Servers (208.67.222.222 & 208.67.220.220) but im sure putting in the gateway IP address would have worked too.
So, by now if you need this I am sure you are excited and want to get to it. Like i said there are probably other ways of doing it, ways that don't involve you installing clonezilla and DRBL, maybe even just DRBL is needed, maybe one of them installed whats needed as a dependency- all I know is it works, if you know - elaborate so people know, but hey- this way not only do you have internet access on all PC's you can deploy custom images to them as well.
I am new to Debian. I am trying out the live cd but can't seem to find how to connect to the internet. My setup is Ethernet card and DSL modem, no routers, no wireless. How do I set this up?
I have a Opensuse 11.4 workstation that has two ethernet ports and I was wondering if there is the chance to use the other ethernet port as a switch to a Mac/PC?
I just installed Fedora Core on my Dell Inpsiron B130 laptop and I am having trouble connecting to the internet both wirelessly and with an ethernet cord into the router. When trying to configure my network, I dont recognize any of the ethernet adapters in the drop down list. I have been told that my wireless card is Linux compatible (dell y8029 dell wireless 1370 802.11/a/b/g mini pci). My ethernet card is a B130 Broadcom Ethernet Driver which isnt in the drop down menu either.
I read that I need to download an ndiswrapper but I dont know where to find this download AND even if I could download it to a zipdribe, I have trouble opening a USB flash in Linux becuase its not a "valid block device". This is after the command "mount /dev/sda1 /mnt/usbflash"
