Ubuntu Networking :: Won't Connect To The Internet ?
Jul 24, 2010
I just installed Ubuntu and it won't connect to the internet. I have an HP Pavilion dv4 laptop. On the top of my keyboard area has my power button, volume and wireless switches (they're all touch sensitive). Anyways, when the wireless is on, the light is blue. Whenever I log on to my Ubuntu account, it just has an orange (meaning off) color, and I can't switch it to on (blue). I'm running Vista 64 bit right now.
On this box I have Two seperate Ubuntu installations. Recently in both I seem to be having the same problem. I initially can connect to the internet as per normal and use any internet application. But after a period of time, sometimes just minutes, sometimes hours, even though the icon says connected, I cant update pages or send emails etc because there is no actual connection. My Physical connection is good I know - My Ubuntu laptop and Windows gamming PC connect fine during this period. So
Does this suggest an intermittent hardware fault or is there some thing in Ubuntu I can check to make sure that it is setup correctly and nothing has been corrupted? I am a lay PC person - I dont really want to be command prompting - Plug & Play and Point & Click is my limit.
I tried to install Xubuntu 10.10 Maverick as dual boot on my laptop. However when xubuntu is on, I can't find a way to connect to internet. When I try the 2 arrows on the up-right corner the option for wireless is deemed. I tried offline/online, that did not work either. when I click the firefox It says you are not connected.
I am trying to setup a dhcp server for my internal network. I have two NICs, a modem, and a wireless router. I have my server connected directly to my modem which is providing me with Internet access on eth1 and is working fine. I have dhcp and dns setup on eth0 which is connected to my router. The router shows that it is connected to the Internet but when the router gives a client computer an IP address, the client is unable to connect to the Internet but can connect to the router. I will post my configuration files below with my current configuration.
I can connect to the internet through wifi, but I cannot connect to anything on my network. I have a printer and a NAS, so I would really like for this to work again. I have a dell laptop with a Broadcom card.
I had put my computer on standby and when i restarted it, it powered off within a few seconds. I turned it back on and after that i've lost connectivity to internet on Ubuntu 10.04.
However I have VMware (XP) installed and internet/network works on that. I'm a newbie with Linux.
Here are some outputs:
I have tried to edit the connection using System>Preferences>Network Connections. I entered manual settings for IPV4, but whatever i enter there, it doesnt get reflected when i type ifconfig in the terminal window. I tried setting it to Automatic DHCP as well. Doesnt work.
I've recently set up a local development webserver using Karmic Koala. I downloaded and installed the server version of Kubuntu and have the web server working.
The problem is that for some reason, I'm no longer able to connect to the internet. I can connect to my router, and other machines in my network can VNC into the server.
I'm using an wired connection to the router and have the server set up on an internal IP of 192.168.0.100. I used to be able to connect to the internet, I downloaded and installed a load of packages etc before it stopped working.
The last thing I remember doing before it stopped working was that I installed Samba so I could share files with the other machines on the network (two Macs running Leopard and a WinXP laptop).
I got the share working - I copied a load of files to the server via the share, rebooted, and for some reason now I can't connect to the net (and other machines can't see the Samba share either.) However I can still VNC into the server.
When i boot my computer and open ubuntu version 10.04.1 the internet wireless connection i have connected automatically. Now, for one reason i don't know, the internet did not connect to the internet. The progam display a message to uncheck the checkmark in the File Menu. After doing this, i refresh the system but it still not connect.
Yesterday I helped my neighbor install Ubuntu 9.10 on his PC. This PC had XP with many bad viruses is the reason for the change. This is not a dual boot setup. Strictly Linux. I know the hardware is fine because DSL communications was working at the time of the install.
I've found a few threads describing problems with the Network Manager and DSL. [URL] I'm in kind of a "chicken and the egg" situation. This Linux PC has no internet connection right now and many of these fixes are downloads via the terminal. However, at my house, I have XP running and online. Can I download these fixes and copy to a flash drive and install on his Linux box?
I have a Ubuntu desktop on my LAN that has suddenly stopped accessing the net, this morning it was working nicely. The computer DHCPs an address successfully, and it can access other comps/services on the LAN. Other comp have no trouble accessing the web.I've pinged my gateway, and I get a response, but pinging Google for example gets me a 100% packet loss.I've tried to release and renew the IP using dhclient, I've unplugged and replugged in the cable at both ends (didn't really expect it to work since it can dhcp fine), I've rebooted the switch, the router, and the comp, still I'm getting the same problem. I haven't played with any firewall settings either.
I'm just using Ubuntu for the first time, and am trying to get everything working on the Live CD before I install it. The only problem that I'm having right now is getting connected to the Internet. I'm trying to connect to my router, but it keeps asking for the WEP Key. I type it in and it pops up again a minute later. It works on Windows, though. I'm running Ubuntu 10.04 on an old Inspiron 8100 I got from a friend.
I'm pretty new to Ubuntu, and have run into problem after problem with networking. The current one: I can't ssh out or connect to the internet, and ping gives a "unknown host" or "network is unreachable". But I can ssh into my computer from others on my network. "route -n" gives 2 entries, neither of which is "default", which from my reading it seems like you need, but I don't know how to remedy that. Is this a DHCP problem?
I'm on a university network, so I doubt it's a problem at their end, but I don't think I changed anything when this suddenly stopped working. On a more meta level, is it normal to run into a different network connection problem every few weeks? I'm not touching anything, I swear! Every linux user I know seems to know ping/ifconfig/route/netstat like the back of their hand, and if it's always like this, it's enough to drive a girl back to windows.
Both ethernet and wireless connections are down, Windows on the same machiene works with both - not hardware problem. Networking is enabled in the applet, but WiFi indicator and ethernet adapter indicator do not flash. Problem appeared after I closed the lid of the laptop at night (set to suspend), but next morning battery was empty indicating that it failed to suspend. I could not find any "hardware manager" inbuilt to turn devices on.
I don't like using Windows, and internet is a necessity.
PS It's Ubuntu 10.4, Gnome on Dell Inspiron 6400 (x86)
i want to connect to Internet via 3G key. But in our country, the operator who is offering that service mentions that 3G key is not compatible with Linux OS. But, when surfing on net, i found some scripts that makes such a service working with Ubuntu 7.xx. I wonder if there is a solution with Ubuntu 10.10
I just installed Ubuntu 10.10 and it works fine, but will not connect to the internet. My wifi card has a CD with drivers, including one for Linux, but it has no 'install' file. I have ZERO idea how to even get to a command line place in Ubuntu [NOR what I'd do or need to do if I got there!!!!] - and need desperately to get online, for all the obvious reasons and to download all the missing drivers needed for things I do. My wifi card [if it matters is a ASUS 802.11n Wireless LAN Card PCE-N13.When I look at what is in the Linux driver folder is foreign to me as Chinese...so those trying to explain, please realize this is my FIRST Linux install and I don't know the terminology...and lacking internet can look up nothing.
I am unable to connect to the internet through DSL. I can use it in Windows 7 easily. I use a Broadband PPPoe with an user name and password along with a service name. I have set up a DSL in ubuntu and I have placed the required user name and password there and I have also entered the service name in the field between the username and password. But it shows to be disconnected every time i try to dial the connection. I have also tried with the "sudo ppoeconf" command and "setpppoe 1.0 software" and failed.
I cant connect to the internet, when i am about to connect to the internet its says you are now offline, then when I put my WPA key in and it starts to connect and when its finished connecting it says you are now offline again, the network name comes up but i cant connect
I tried using the ubuntu 11.04 cd but it didn't work so I had to dig out my old ubuntu 8.04 livecd. I had a computer with windows xp totally get wasted and I decided to do a clean install with ubuntu 8.04 and update to the newer version, however I cannot get the internet to connect (wired), I've tried figuring out of there is a driver problem but was not able to figure it out.
I have installed ubtuntu 11.04 from 10.04. Everything went fine i was surfing the net without any issues. When i turned on my laptop today to use ubuntu It won't let me connect it keeps saying check my internet connection.I didn't change nothing. I just updated the stuff in the update manager and rebooted and laptop was fine. But now i can't get the net to work on ubuntu. I know my net work cause i have windows 7 installed on my laptop to.
I just uninstalled ubuntu and reinstalled it thinking it would fix my issue but it didn't.On ubuntu 10.04 lts the wireless worked the first day then next day only wired connection worked. I am not sure what to do or how to fix this issue its buging me alot i love ubuntu as much as i love windows 7. I been surfing the net for help on how to fix this but they don't seem to help. And i am still new to ubuntu so step by step help will be good cause i just installed ubuntu last friday. If you need need more information let me know.
I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.
I have installed fedora 12 recently. after installation i tried to connect to the internet using BSNL broadband connection. I filled in the details such as IP, Netmask, Gateway and even DNS servers. In the services also I ensured that the network manager services is on. However even though my computer cannot connect to the internet. I then tried the ping test of the modem from the address 192.168.1.1 and found that the ping test is successful. Then i tried the network administrator and there I noticed something unusual.
There are two options in the devices eth0 and eth1 thats ok but the unusual; thing is that the Activate (green button), Deactivate (red button) and even the delete buttons are in the background and I cannot select them. Isthis the problem for the network connectivity.

I recently upgraded Ubuntu 9.10 from 9.04 but I was unable to connect to the internet. I have a ppp connection and I used to make a DSL connection and then give the command 'sudo pon ppp0' and the net got connected but in Karmic Koala it just doesnt click. I switched back to 8.04 and its working fine with 'Roaming mode enabled'. There is no problem with my connection. And also if it gave some problems then I used to delete all the connections I made and then reboot and then 9.04 would make a connection by itself but 9.10 doesnt. I installed 9.10 within windows using wubi. Please help as to how should I connect to internet in 9.10? I am attaching the ppp0 file so u may suggest the right connection for me if I am wrong.
I just installed Ubuntu 9.10 and everything was ok util I was going to connect to internet. I just cant't find any way to connect to any wireless networks. I'm living in a board school so wireless is my only way to connect to internet. I have a Dell latitude e5500 and I can without any problem connect to internet on windows that I also have installed.
I have been on snow leopard and widnows 7 all my life. I just installed ubuntu on my other computer and I can't connect to the internet.
