General :: Unable To Get Internet Connection On Startup
Sep 22, 2010
When I boot up my machine (running CentOS 5.5), I have no internet connection. ifconig doesn't show that eth0 is present. Going into my Network Gui from the administration tools, it says that eth0 is not active. I can't activate it from the GUI.But...If I sudo dhclient -d eth0, the process runs for a little bit, and all of the sudden my internet connection is there.
There must be some sort setting that I need to change to avoid doing this everytime I start the machine. Its odd, because I have an identical machine right next to it that doesn't have this problem.

I am unable to connect to the Internet using a wired connection. I was able to use the wired network yesterday. But I had problems with the flash player, so had to reinstall Ubuntu again. I am able to connect to Internet using wireless connection. But I need to connect to the wired connection. I am using Ubuntu 10. In my IPv4 settings, it is automatically set to DHCP, using which, I was earlier able to connect. But now it doesn't seem to be happening.
But there are other entries on the syslog that were recent.
Output of dhclient

After upgrading to Ubuntu 10.04, I'm not able to make any connection to the internet with either my netbook through WiFi or my computer on wired LAN. I can, however, ping my Solaris machines and Macbook. How do I fix this?

I have little to no understanding of this system. I am currently setting up for a work from home job that requires I use a disk in my CD drive when booting my PC. I believe this disk runs an ISOLinux operating system.
The system appears to boot properly; however, I am receiving an error that states "No Address Found" and I am unable to get an internet connection. When running Windows Vista, my ethernet connection runs fine. I'm sure I am missing one small piece of the puzzle that will make this work.

I've very recenty installed Ubuntu v 9.10(64amd) but am unable to setup my internet connection.I've gone through quite a few posts where other users have faced the same trouble trying to setup a DSL connection.I've entered all my Ip4 settings as they are on Win..but that hasn't helped.That didn't open my modem settings page either.Modem model : SmartAX MT882 connected via Ethernet and not USB.Can't quite figure out what I'm doing wrong/need to do.

recently installed Ubuntu 10.10. Everything seems to be working fine on the installation except I have never been able to connect to the internet (I'm on mac connected to the same linksys router at the moment). I've been working on this for several days and have exhausted all the possible causes. Here is my setup.
My setup:
-I have tried running both 10.10 and 10.04 (I have 10.04 installed at the moment)
-I have windows xp on a separate hard drive on the same computer and the internet works fine when I boot in windows
-I have tried both automatic DHCP (which my windows uses) and manually connecting to my network under the IPv4 settings
-my "Connection Information" info under networks manager has all the correct information listed as far as my driver, IP address, Bcast, mask, DNS serves are concerned (except I don't know what 'default route' is for so I can't verify that that is correct.)
-my ethernet connection is wired connection that is connected to a linksys router
-my ethernet driver is sis190
-I can ping my router successfully, but I cannot ping anything (i.e. websites) on the other side of my router

I am using Empathy IM client to access to gadu gadu and to message with my friends. The strange thing that is happening is that I keep on being connected and then disconnected and then connected again even if I am continuously connected to my internet connection (no problem when surfing or using skype for example)It also seems to come only from me because when my girlfriend is using the same gadu gadu on her windows laptop simultaneously, she doesn´t get disconnected (whether when she is at home and using the same connection as I am or when she is outside, meaning that it doesn´t seem to come from the whole gadu gadu network)maybe it has something to do with the ports that gadu gadu is using but it is strange that sometimes it is working for a period of time and then not and then again.

I have recently installed ubuntu 9.10. Earlier I had ubuntu 9.04. On that my internet was running perfectly well.After installation I created new connection as I had done for 9.04 version using "Network connections , Edit connections". However, after configuring connection(uname , password etc.) I wasn't able to access Internet.So I tried using "pppoeconf" utility. After using this now whenever I click on network connections applet on top panel , it shows in menu "device not managed".Can somebody point out what went wrong and what to do so as to be able to acess Internet in ubuntu?

I just installed Ubuntu Netbook 10.10 on my Lenovo ideapad S10e. Under the network manager it says that firmware is not installed for the wirless card but that is something for a different day. On the ethernet connection it attempts to connect via dhcp and then comes up saying it is disconnected. I attempted to set it as a static connection, when i do that it shows that its connected but I still can not connect to the internet.

when I was still at my university room where the connection would work after a few reboots. After moving back home the connection worked on and off for a day before not working at all. NetworkManager is telling me that I am connected and have an ip address, etc, but nothing is able to get an internet connection. I am able to ping myself but am not able to ping my router. Everything works fine on M$ and other PC's on the network, it's just my ubuntu 10.04 that is playing up.

I would like to have all traffic from the ethernet connection out through the wireless (basically using the box as a router) however I am having some trouble doing this.
I have done this before on Windows however I am having some trouble doing this on linux, I have tried using Squid Proxy however I am having some trouble using configuring/using it.
I am using Yellow Dog Linux however I am willing to change to any other distro as long as it is compatable with PS3 (as this is what im using linux on)

I recently installed Ubuntu 9.10 on my Dell Inspiron 1545 64-bit laptop. Before that I used Windows7. In Windows, the internet connection worked perfectly well. But after installing Ubuntu, I am unable to connect to the internet. The network-manager applet finally says that "You are disconnected". When I do the "ifconfig", I got no IP address.
So, I installed Ubuntu 9.04 in the same system. But the problem persists.
I gone through many posts in this forum but nothing was useful.

I wouldn't be posting this if I hadn't tried very hard for the past week to do this on my own, but alas, I failed. I have this two configurations:
Desktop:
- Ubuntu 9.10
- Connected to the internet though a wireless card
- Connected to "Laptop" via wired network with a crossover cable
Laptop:
- Dell latitude
- Ubuntu 9.10
- Connected to "Dektop" via wired network with a crossover cable
The wired connection is working, both computers are able to ping each other, but I haven't managed to share internet, nor files. I have tried many different ways, from setting the wired network to "Shared to other computers" to this guide in the Ubuntu Wiki. The best I could get was for the connection to work by setting the IPs manually, whatever else I try results in either nothing or in a not-working connection.

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.

I am running Ubuntu 10.10, and I would like to use my computer to share the internet connection from an ethernet port. For example, I would like to set up my computer as a wireless access point so I can create a network that other computers can connect to for internet.

I have been using the 3 OS regularly with no problems. But today suddenly, I had no internet connection with the 2 linux partitions which are complete independent, but no problems with windows. i can keep using the internet under windows with no problems.
I haven't touched any conf files.
I have a usb wifi internet connection.
I just noticed a change in my dmesg file when i start any of my 2 linux partitions.
At the end of the lines I have the following :

I'm having a problem connecting to the Internet on my gNewSense installation. My Internet works fine through Ubuntu and Windows, but not through gNewSense, is there anyway of fixing this? Also, while searching around I found that somebody said I ought to type "dmesg" and copy the results.
Code:

I just downloaded openSUSE 11 but I don't have an internet connection. I thought that it will find my cable connection automatically like Ubuntu does, but it didn't. It doesn't have a normal network configuration set-up, there is nowhere that it even gives me a choice to select local internet connection or a cable connection. What do I have to do to set it up.

I am new to Linux. Just installed Ubuntu 10.04 few days back. The problem I am having is not able to connect to internet. Mine is direct cable connection using CAT5 cable terminted to my ethernet card. and I connect to the net using a dial-up connection. I think other end of the cable is terminated to a common switch.I have tried searching it over net. The only thing I could figure out is that I have to do some configuration on pppoe (am i right?)Are there any commands I have to enter or anything like we used to do in windows?

I have a Fedora core 3 box that I am trying to use to replace my current document server. This box was part of a domain at a different location previously. At this location we use a "work group" network. I have set the IP, Gateway, Subnet, and DNS servers. I can see the machine from my XP machine, but cannot get a connection to the internet?

I have just installed Linux Mint 8 Helena & it appears to be working well alongside my xp system. The problem I do have is setting up the much needed broadband connection. I have an adsl speedtouch330 usb modem, with tesco.net as my server, which works just fine on xp hence this mail. Am I missing something obvious, or have I got myself into depths much deeper & complex than I thought.
