Ubuntu Networking :: Could No Longer Connect To Internet ?
Mar 8, 2011
Installing, reinstalling different distros, flavors, on dual-boot (XP), for almost year & 1/2.
Never problems with accessing internet. Ubuntu varients, Suse, mostly.
3 weeks ago, downloading new Mint ISO with bit-torrent. Did not complete the download.
Soon after this, abberrant behavior began - could no longer connect to internet. After exploring, appears that network is not enabled. Played with configuring / editing - seems to be correct - but still no more connection.
Several times wiped disk, reinstalled. Same behavior. AND Live CD works - always goes through (using it right now to access this site).
What condition could/would persist through various reinstallations, but not affect Live CD use?
Also in the network - Linksys router, vonnage phone. But no previous trouble.

I have an Intel Mac that I recently added openSUSE 11.3 to to have a dual-boot system. This has been working fine for me for the last 5-6 months. Then on 1/18/2011 I shutdown my system and totally disconnected everything and moved it all out of my office, so new carpeting could be installed. After it was installed, I reconnected everything and confirmed that everything on my Mac side works just fine. Then I rebooted into Linux and everything worked until I tried to run Firefox to connect to the internet. I'm told every time that it could not connect to the server for whatever I tried to connect to. I AM NEW TO LINUX AND ANY KIND OF NETWORK/INTERNET PROBLEMS, SINCE I'M USED TO MAC WHERE EVERYTHING JUST WORKS. But, I did click on "computer" in the lower left-hand side of the menu bar at the bottom of the screen. This shows on the right-hand side under STATUS "Network: none" and then it states to click this to get it started or connected (I don't remember which) so I click it. This brought up a window asking me for my password and then a new window where it went through a checklist of things and presented me my network settings, which
means nothing to me. However, after this I tried Firefox again with not luck.

can no longer access the internet,Deleted Network Manager thinking I could reinstall it and it would be back to its default settings. Had not been able to get online for days. Offcourse now I can't get Network manager back as I have to be online for that. I think I had stuffed up the proxy settings but can't work out how to get that back to default either. What do I do now and how do I do it?

I'm running 10.10 on a pretty fresh install with a brand new system I built especially for Ubuntu.For some reason, I'm beginning to have trouble with accessing my Samba shares from this computer. I have a Windows Home Server also running on my network and I have to be able to access the files on it.At first Nautilus showed "SERVER" in the folder tree when I clicked on "Network" and everything was working great. A couple of days ago my WHS "SERVER" suddenly no longer showed up in Nautilus and I had to mount the WHS server manually (via "Connect to Server...").
Now, today, even that doesn't work. When I try to mount manually I get the error "Failed to Retrieve Share List from Server". I can now no longer access the WHS from Ubuntu at all.Why has my ability to access the Samba shares on my WHS deteriorated over time to the point where I can't access them at all?? Any ideas?I have other systems on this network (Mac and Windows) and none of the others have any problems at all with the WHS. Re-booting WHS and router has no effect. I've changed nothing in my set-up. Is this update related?

I have been a happy Fedora user since late in the F9 release and now use F11 32 bit.Two days ago my 2wire modem/router took a dive. My ISP sent us a Motorola 3347-02 and since then my computer will not reach the internet. I have read everything I can and still haven't found the solution! Some things that I have tried: Disable network manager and do it manual, configure static IP, wipe system and reload, installed F11 on another computer.None of these have worked.Now I am booting from Ubuntu and have no issue but I can't stand Ubuntu.

I used the "Upgrade" option the last couple of nights to go from 8.04 LTS and was going to go to latest version. Well got the upgrade done last night on 9.10 and now Broadcom gigabit wired connect will not connect to internet. Can ping router just fine. Just cannot get outside of it. Shows as configuredin ifconfig. But the name of it under the network manager is odd. Its ifupdown (eth0) (default) and maps to ent1.

My wired internet was working fine and dandy under Maverick until today. For no apparent reason, it stopped. The router works fine. All other computers are able to connect. I've tried using different cables with no luck. I have a Biostar A785G3 motherboard with an integrated Realtek RTL8111DL ethernet controller.
My problem sounds very similar to this guy's: [url]. But his strange solution didn't seem to work in my case.

I am running Jaunty 9.0.4. I have go through a proxy to get out to the net. It was working. Sometime yesterday it was unable to resolve the proxy server. Can't even ping it. Other computers can. I even switch cables to no avail. What could block the proxy server? I can't even ping google.com Was it something I installed through add/remove software? Has anyone seen something like this before and even better has a solution or can offer a way to troubleshoot this? I can ping myself and the default gateway server.

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 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.
[Code]....

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.

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 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.

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.
