Ubuntu Networking :: Wired Network Connected, But No Internet Access?
Mar 24, 2010
Background infoMy laptop (MySN MG6.c) is dual-booted with Windows 7 and Ubuntu 9.10, and connected to the internet through a router (Digitus DN-11004-O), which is set-up to use DHCP. The internet connection works fine under Windows, and my previous laptop, which also ran Ubuntu 9.10, had no problems connecting to the internet through that router.The network adapter is an Atheros AR8131 PCI-E (also detected as Attansic under Ubuntu)stem infoResults from running various diagnostics (I have removed the output that relate to the wireless connection, as I don't use it):

I have a wireless network (192.168.1.0) that's bridged to the Internet and a wired one (192.168.0.0) that's only local. When I am connected to both networks, Natty wants to route my Internet traffic through the wired, local-only one.
Can I make it automatically "just work", so that the right network is chosen for Internet traffic? Otherwise, what's the workaround?
Okay, a couple of weeks ago I was running 10.04, got an auto update that needed a firefox restart, so rather than restart, I just shutdown the computer for the weekend. When I booted the computer on Monday it would find sites (www.google.com, start.ubuntu.com) but it wouldn't download the necessary items to load the page. Now I have a windows laptop sitting next to the ubuntu box and it was online with no issues, so I know it wasn't the connection itself. So I decided that the update messed up the system so I downloaded 10.10 and installed that and ran that all last week.
On Friday I got a system update that required a firefox restart, so I ran firefox for the day and decided that since it was friday, I would just shutdown the computer and reboot on Monday.Well now Monday is here and now I again have sloooowww internet, to the point that URL.. times out and won't come up. I have tried doing a traceroute on both machines and the windows box gets all the way to www.google.com, but the ubuntu box gets about halfway there and then gets no response. I am at a loss, I don't want to reinstall every week. I did try to reboot and run the previous version of 10.10 that shows in the boot menu, but that does the same thing. One thing I did notice is that the broadcast ip is different than the machine IP, don't know enough to know if this is a problem.
can't access internet. The up and down icon appears by the network connection (upper right hand corner). When I review connection properties, I see that the computer has a valid address, subnet, gatway, dns, etc... But it still can't connect to the internet. I can't ping external addresses either. But I can access internal addresses (local router).
I just got a new power supply in my old desktop, and installed ubuntu on it. I've got three NICs in there (for a later project), and when I connect my cable modem to any one of the NICs, then little connection triangle-spinny-thing in the upper-right tries to connect. But it never gets all the way connected.
I have installed Linux for the first time on an old Gateway purchased from work. The system seems up and running, but I can't get connected to my wireless or the wired network. I have tried using the network manager, but it isn't working. I have tried reinstalling Fedora 12 I have the following LSUSB and LSCPI output.
This may be more suited for the networking forums, but I figured Community Cafe would be well rounded enough for someone to tell me if this is even possible (with minimal configuration that is).There are a few places I travel where I only have a wired connection to the Internet (no wifi), but when this happens is there a simple way to create an adhoc network so wireless devices can route through my computer and to the network? Reason I'm asking is I'm thinking of getting an iPad or iPod Touch which have wireless connections, but in the cases where my laptop is using a wired ethernet connection and the wireless card isn't used, I'd like to create an adhoc wireless network that'll let such wireless devices work.
im using mandrake linux 2010.0 , and i connected my router cable (dlink) to the computer, and it detects without needing configuration to the 'eth0' and it shows me the ip the dns and gateway, everything ok, but then i go in firefox it says that i couldent connect because theres no internet connection,ive looked at the proxys the firewall, tried to uninstal the eth0, the ppp0 and install then again and still the same,does any one have an idea of what could be?
I've installed Fedora 13 on a Toshiba Satellite A40 laptop, and am trying to get the wired ethernet connection to work. Network Manager says it is connected, and the connection details (DHCP assigned IP, gateway, dns servers) all seem correct. However, I cannot browse the internet. Checking for updates fails also. I have tried pinging various sites and the results are inconsistent - sometimes it works, sometimes it times out with "unknown host". [URL]... I've searched around for similar issues and tried disbaling ipv6 both in Fedora and Firefox, but this doesn't help either.
When I connect my PDA (AT&T Tilt with Windows Mobile 6.1) to my desktop via USB (my desktop is connected to Internet via LAN), I can't access Internet from my PDA. How can I share Internet from my desktop with my mobile phone?
p.s. I can only find how to access Internet on a desktop using a mobile phone as a modem.
I've been using my upstairs computer with no problems recently up until this evening, when I rebooted it did an automatic scan of my disks, so I left it to it's thing and when I came back ubuntu had successfully booted, and had seemingly successfully connected to my wireless network as usual.
I've been through the wireless troubleshooting guide, paying special attention to sections 4 and 6 but to no avail, while I'm apparently connected, and have been assigned an IP by my router I'm unable to access anything outside my computer, including the router itself. This happened before, however I solved it by reinstalling ubuntu, and I'd rather not do that again!

I am facing very strange problem with my Dell with WiFi card (04:00.0 Network controller: Intel Corporation Wireless WiFi Link 5100) It seems I am connected to the WiFi but can not access internet I have to disable networking and re-enable it to access internet.
I have installed ubuntu 10.04 and STA wireless driver. I am using a wimax modem, the wireless is connected (have IP addresses) but I do not have access to the internet.I also have installed a windows XP as a guest OS (ubuntu is the host) on vmware. By using a bridged network connection, I am able to access internet. So I guess the problem is related to the ubuntu wireless driver.
I installed the driver for my network card. iwconfig and ifconfig are all responsive to connecting to the network, I'm given an access point address. Then, I try to connect to a website and no dice. ping www.google.com yields no result. What gives?
I have internet from KabelBW (cable modem which doesnt require any username,password,dns,mac...) they gave me a cisco modem, I connected it with my asus router and it has been working fine since today! when I woke up I turned on my lap top and loged in skype, but I couldnt open google, then I tried yahoo..nothing! I havent made and changes yesterday! I dont know what is wrong! I am new to ubuntu and I dont know what to do! when I connect directly to modem I have internet it works good, but when I connect through my (LAN or Wireless) router I cant view web pages. I have tried to google for the answer but all the answers are for windows OS versions! I tried to restart lap top, and the router 100 times but nothing!
On the 25th of January, one of my computers randomly stopped being able to connect to the Internet. It was running a dual boot (Ubuntu 10.04.1 LTS & Windows XP SP2), and is connected to the network via an ethernet cable (no wireless). According to the Network Manager, everything is working okay (there was no change from when I was able to access the Internet).
When I would use Firefox, I would get the message "Waiting for (page)...". However, this is not a Firefox only problem, as every program requiring Internet access (e.g. Evolution) is unable to connect to the Internet.
I compared the Internet settings to those of my father's Windows XP SP1 computer, which is able to connect to the Internet. There was no difference, except for the IP Address and Hardware Address. Because of this, I incorrectly deduced that either the actual Ethernet cable or the wall plug was faulty. I tried using a different cable and connecting to the Ethernet wall plug used by the aforementioned computer. Nothing changed. I was still unable to connect.
I didn't worry about it until Tuesday, when my other computer had exactly the same problem. It is running a triple boot between Ubuntu 10.04.1 LTS, Ubuntu 9.04 and Windows XP SP2, and I am unable to obtain Internet access using any partition. As with the previous case, my computer showed no change in the Internet settings, and the computer also shows it as being connected to the network. It is also connected via an Ethernet cable.
I have a Toshiba Satellite L505D-GS6000, and I installed Ubuntu before and it worked flawlessly until I decided that I had to go back to Win7 because of certain program compatibility issues.I'm back here trying to set it up and am having no issues except for with my wireless. I can see all of the SSID's, I am able to connect to my wireless, and it displays that I have been assigned an IP and all of the other settings given by DHCP.
I have been trying to fix this for hours, googled, searched these forums, and have spent time with some people on the Ubuntu IRC channel and we are unable to come up with a fix.
The strange thing is that although nothing will load when I try to visit facebook.com, google.com, or any other website... I opened the update manager and I noticed that it would download for 30ish seconds, stop and do nothing for 60ish seconds, resume for another 30, stop, resume, etc. until it finished. I am able to ping my router, and 184.108.40.206, but I am unable to ping [URL].
I am working on ubuntu 10.10 in a VM. I went ahead and did updated the system when prompted. That has disabled my wired network connection. I am not sure what is the reason. If it is a device driver or any network service. I guess device driver is not an issue as I can detect my network card from ubuntu. Does any one know the solution?
we are trying to install this NIC Rosewill RC-400 Chipset RTL8169S-32 in Ubuntu 9.04 we downloaded the drivers from Rosewill website (For kernel 2.4.x and 2.6.x V 3.1) but when we follow the instruction in the readme file and do make clean modules and error comes out
So I went do realteak downloaded latest available drivers that seems to be were release yesterday did same command and same error So I made only make and it went fine did then make clean modules and went fine so made make install, depmod -a and modprobe r8169 verify int was up and getting correct ip from router but I'm not able to access the internet or ping any IP address

I upgraded to 10.10 the day it came out, and haven't had any problems with internet stuff. My wireless card works without any proprietary drivers. Last night, the computer stopped connecting to the internet. I am still connected to my wifi network, but I can't do anything online. I had assumed that my internet connection was just down in general, and tried resetting the computer, shutting down the computer and then turning it on again, and rebooting the modem, but then my Xbox connected, and my laptop running 10.04 connected, so I'm confused as to what is going in. Any ideas?
Each of those commands don't give me any error and it would seem like everything works fine, until I try to ping google or any website and I get an error that tells me that no host was found. I am using version 10.04 of Ubuntu server.
I'm having trouble getting onto the internet with ubuntu 9.04. I have just moved house and have just got the internet set up here (typing this on windows laptop with wireless). My ubuntu desktop is plugged in to the network, but in the top right hand corner when I click on the network icon I get: "Wired network device not managed"
In my old house I had a static IP. Is this anything to do with it?
A few days ago my wireless windows vista computer internet was running slow so i reset the modem. Then I went on the internet on my ubuntu machine machine and went to www.google.com and couldn't connect to the server so i tried linuxquestions and i couldn't connect but i could ping sites. My wired and wireless windows computers worked fine. So I called Comcast (my ISP) and said it was a router issue. So I looked online and it said to disable IPv6 on firefox so I did but that still didn't work.
I'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.
My friend has 2 pcs, one connected to the internet and the other one used to connect (when he had windows installed) to the internet through the first one using internet sharing, now i installed ubuntu on both and the network between them has been created but it wont connect, the internet icons just animates for like a minute then says "wired internet disconnected" in other words it failed to connect.
I just installed a dualboot win7/F15 on my laptop (dell XPS 15) and everything seems to be working fine except that when I connect to my network it is connected and the network is accessible (I can visit my gateway/ router) but when I try to visit a website it simply never ends loading it.Internet is working on win7 so it isn't my network's fault.Now I found somewhere that updating could help but since I dont have internet I can't update
got an asus wl500gp v2 and i just had to reflash it. Flashing went through fine, but while setting up the PPPoE connection I got stuck. Here is what the configuration looks like:ADSL Modem ---Ethernet--- Router ---Ethernet--- Laptop I set up OpenWRT to connect over PPPoE over the WAN port and the connection is established:
