Ubuntu Networking :: Wired Network With Internet Connection But No Access
Mar 28, 2011
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.
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):
Code: $ uname -a Linux valyria 2.6.31-14-generic-pae #48-Ubuntu SMP Fri Oct 16 15:22:42 UTC 2009 i686
After i install it i lost my internet connection . i got a message " Wired Network " " you work offline ". i use cable ADSL ,.... my Pc information HP Pavilion 6700 running with both Window 7 & Ubuntu 10.10 note... my network connection work correctly on W7.
I am attempting to connect Ubuntu 9.10 to the Internet.I have a network connection, and Karmic detects it fine. I can ping addresses within our network (e.g. the Windows computer in the next room), and I can ping the router, but if I ping, say www.google.com, it says "Destination Net Unreachable". Previously, in Jaunty, I had a similar problem.I found a workaround: launch Pidgin. Somehow, launching Pidgin temporarily edits my configuration. However, in Karmic, I have no access to Pidgin, however, and Empathy does not do the same thing. Since I have no Internet, I cannot "sudo apt-get install" anything.How can I get the Internet working?
I keep losing internet connectivity from within OpenSuse. I've had ubuntu/kubuntu beforeand never had a problem. I installed opensuse and now after a few minutes of browsing I'll lose my internet connection.I also dual boot into winXP without any problems.I noticed that when the connection is lost I can't even reach my router - which is where I'm getting the wired connection from.So it's not just the outside internet but the local network too. It only happens within opensuse.
I have just done a new install of the latest opensuse 32bit and for some reason I cannot connect to the internet, when I click on mange connections the vpn tag is highlighted and all the other tabs are grayed out and I cannot select them. So I can't setup a internet connection wired or wireless. I was just using Kubuntu and did not have this problem. My card is broadcom.
After installing UNR onto my dell mini 9 and downloading the correct drivers to enable wireless internet (using this site: [URL]), I decided to load ubuntu onto my brothers netbook. After the installation completed, I went to do complete the steps listed in the above article, however I was unable to connect to the internet using an ethernet wire.
I have BIG troubles trying to set up wired internet connection in Ubuntu! To be able to connect to the internet I have to enter my MAC address, 2 IPs, netmask and 2 DNS address. When I try to edit the default internet connection eth0 with my correct information, the minute I enter my MAC address and save the changes the network manager creates new internet connection with wrong data and use it instead! I can't select the correct internet connection from the top bar where the internet icon is, because it is just not there. The only connection that I can choice is the new default one with the wrong data! If I try to create new separate internet connection with my correct data the same thing happens! The moment I enter my MAC address and save it, the internet connection disapears from the list of internet connections in the internet area in the top bar and I can't select it. I tried googling it, but with no luck I think that if I set up my connection trough the terminal everything will be ok
I have had the exact same set up 10.04 on the same machine connecting to the net with no problems. I had upgraded from an earlier version.
This time with a fresh install from disk the network manager does not see any connections. How can I get the manager to recognise the network and connect to the net?
I realise that it would help if I posted up the output of some commands in a terminal but I am writing this on my phone and can not cut and paste large chunks of text. I can only hope for some advice until I can get to a computer with a working connection.
Ubuntu 10.04 AMD dual core 64 bit with wired 10 meg broadband.
How can I get the network manager to see the connection
I have an old Compaq Presario v2000 that recently had Ubuntu 10.04 installed on it. The wired internet worked when it was installed, but the wireless didn't. I tried to download the drivers for it and it failed everytime. I did an update thinking that the update might fix the wireless, but it didn't, it actually made my wired connection stop working. So now I have a newly installed OS on the laptop, and I can't do anything on it because there is no way to get any internet.
I've just installed the 64 bit 10.04 onto my new netbook, with ample specs to run the full desktop version rather than the stripped down netbook version. My only problem (at the moment) is that my wired internet connection is not recognized within the operating system, yet while I was downloading/installing Ubuntu it had no problem finding and using the connection then. When I boot into Windows 7 or plug the ethernet cable into my Mac, the connection is established immediately, and no need for manual entering of anything because everything is auto-detected. The really strange thing is I've run Ubuntu off a USB stick and when booting off that the wired connection was immediately recognized after startup.
I have an ibm think pad and for some reason the internet(firefox) stop working and i don't know why , the netwprl settings have disappeared or anything on fixing it , yes i have tried restarting the modem but that hasn't work ethier Also i don't really know where the re-start disk so is there anyway i can fix it with out the disk?
I have just installed a fresh copy of 9.10 on an older Compaq nc6000 laptop. I need some help getting my Linksys WUSB600N wireless adapter to function properly.
I have "half-way" connectivity, meaning that I can see (and connect to) my home wireless network but I can't connect to the internet (unless I use the wired connection). I have installed NDIS wrapper - no change
For the last 3 or so hours I have been trying in vain to simply give my mobile phone wifi internet access from my netbook. I have tried to google and follow some howto's and guides, but they're either too old or don't explain it very well. I'm fairly new to use of Linux and of wireless networks, but can handle setting them up in Windows. So basically, having said that, I believe I mostly understand how this whole thing is supposed to work theoretically but I just feel as though I lack the experience to jump the wireless hurdle AND the Linux hurdle at the same time. I have provided some information below.
- Setup is based on Lucid netbook remix install with a Maverick kernel update due to lack of driver support for wireless NIC - I can confirm wireless does work properly for connection purposes - I followed [URL] and kind of followed [URL however I couldn't even tell how to run Network Manager, even though Synaptic tells me it is installed - When I ran into problems trying to install ipmasq I found [URL] and followed what the response told me to which allowed me to restart the dnsmasq and the dhcp3-server at least - I have restarted the entire netbook several times throughout the process.
I cant get my wired internet connection to work. The command 'dpkg -s pppoeconf' returns ' installed ok installed'. My connection is through a router which is probably in a semi-bridge mode and I need to dial a connection to get the net started. The connection Auto eth0 is setup properly with the correct cloned MAC Address (that of my laptop).
I've also executed 'sudo pppoeconf' and ran the whole series of steps which towards the end said that my connection will be set on boot. However, the net doesnt work directly and I dont know how to dial manually either. 'sudo ifup eth0' returns 'interface eth0 already configured'. I tried some 10-15 threads but none worked. Ubuntu is handicapped without internet.
Ever since my BT Hub 2 has updated a few weeks ago I'm unable to connect to the internet either wireless or wired. I duel boot on my netbook with xp and duel boot my desktop PC with windows 7. None of the Ubuntu�s are able to connect, I have no problems with the windows side of things.
Has anyone any ideas on how to fix this until BT decide to fix the problem. Preferably a step to step guide as I have limited experience with Ubuntu. I�m using Ubuntu 11.04.
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.
I just installed Ubuntu 11.04 desktop on my desktop in dual boot with Windows 7.
Heres my problem, I am unable to connect to the Internet even though my wired Ethernet connection says it is connected normally. The wierd thing about this is that I also have a wireless card in my desktop and when I connect through that I am able to connect to the Internet. I am connecting to a router that is functioning as a repeater to my main router/cable modem. I have tried to solve this myself but am having no luck. Ironically, earlier today suddenly my ethernet connection worked for a few minutes without me modifying anything.
The output of some terminal commands are below.
However a pint to that ip address (my router) is successful.
Hosts.allow and hosts.deny are both fine (not blank but no entries)
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.
As of now, my internet works fine when connected with an ethernet cable.The problem is it doesnt seem like my wireless is working at all.The led light is orange, (its usually blue when it connects) and I cannot see my home dsl network.Is thereany specific troubleshooting steps I should take?HP dv6000 laptopwireless card: Broadcom Corporation BCM4311 802.11b/g WLAN
I just want to use Internet Connection Sharing (ICS) to connect to the internet. I have done a massive amount of troubleshooting, but some of it seems to contradict itself, and the only two things that I know for sure are that it used to work, and that my Ethernet cable is not the problem. When I use Terminal utilities like ifup and dhclient it seems that it can not determine IP information, but when I try to put it in manually, the "Apply" button grays out right after I finish typing it in. When I try to connect normally, in KDE or GNOME, the icon acts like it's connecting, then instead of having the connected icon, I receive a notification that "the network has been disconnected", and it goes back to the disconnected icon.
Oh, and by the way, I know that I could probably find a workaround, but I have limited resources, and this used to work. The Linux is a Dell desktop with Fedora 12 and the Windows is a Windows 7 HP laptop.EDIT: I hope that I didn't mess something up, but I accidentally used system-network-config to try putting in the IP address there, and ended up changing it back to the original settings, but the computer is now calling it Auto Ethernet in the taskbar icon, although sudo iwconfig in the terminal still calls it eth0.
newly installed fedora 15 is not able to connect to internet i have broadband connection with wireless modem my laptop is connecting to wireless modem network. but i am not able to configure pppoe connection on it PS: i am able to connect to internet when using wired connection from modem
I've been reading around, but not had much success at all in trying to share the internet connection from my laptop to my phone.all the articles i read refer to earlier versions of Ubuntu and the packages they mention have become obsolete, according to the apt-get tool.im not that new to Linux, but my networking probably isn't up to scratch.if anyone could help me, that would be great, im using Ubuntu 10.04 at the time of writing.
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.
