Ubuntu Networking :: Unable To Use Internet Connection With 10.10 And 10.04
Nov 21, 2010
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.
-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
My father recently installed Ubuntu 9.10 on my new AMD dualcore, but we have not been able to access the net.we tried resetting the modem/router. Windows XP had no problem getting us online - why is it such an issue with Ubuntu?
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 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.
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?
Its a case of ".... wireless network connection active but still not internet connection .."I am using WEP - 128 key ... Works when I connect directly using ethernet cable ... but not wireless (pci and wireless router)
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 seem to have is trying to get the internet to work. I can go to ..... ect but when I try to run playonlinux it says you do not seem to be connected to the internet, please post if you have anything useful, as I said I am very new to linux so be as detailed as possible.
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.
I have two linux laptops. Currently, I'm using both of them at work, side-by-side. Now the problem is, I'm connected to a wireless router, but the wireless only works on one of the laptops. So I'm stuck with one laptop that has no access to the internet. Both machines do, however, have working ethernet nic cards. So, I was wondering if I could use the laptop with the wireless connection to share the internet connection with my other linux machine and access the internet on both of them. Or as an alternative, just use the internet on the machine without wireless and be able to switch back and forth, that would increase my productivity like 30 fold.
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.
I am unable to connect to the internet connection of my cell phone avaialble via bluetooth.The NM applet just tries for a while and then disconnects.It works fine in windows with NOKiA pc suite.What do i do?
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 the "Work Offline" problem: when I boot up, the icon on the toolbar tells me I have "No network connection". This is not quite true, since I can access the first page of any website - only subsequent pages are inaccessible. I get a message saying that Firefox is offline. However, when I uncheck "Work Offline" in the File menu, it makes no difference to this behavior.
The problem is on my Ubuntu Dell desktop, which is connected to the internet with cable broadband via a D-Link router (wired connection). It has worked fine up till now. I use Ubuntu 10.04 and Firefox 3.6.11. I am writing this on my Ubuntu Dell laptop which is wired to the same router, so I assume the problem is not the router. I have tried various strategies suggested in threads on these forums, including editing about:config, changing "allow" to "deny" in some lines of /etc/dbus-1/system.d/NetworkManager.conf and changing from Automatic (DHCP) to Automatic (DHCP) Addresses only, but no luck so far. The contents of ifconfig are:
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'm using ubuntu 10.04 dual boot with windows xp. Recently I'm having problems using the internet, I can connect to our wireless network but can't use the internet, firefox just says error on opening the page. But when im in windows xp i can surf and use the net. Is their a way to diagnose whats causing the problem. I use a Realtek RTL8187 wireless lan, it works fine before its just now that its not working with ubuntu.
I installed ubuntu 10.10 with windows 7 (dual boot) in my fujitsu lifebook. I use zoom ultra by Sentar EVDO MODEM ST880U. I tried pppoeconf or DSL or mobile broadband but fail to connecte internet. In first exprience on ubuntu 9.04 same via dell latitude with Huawei EC123 Data card.Any one can assist me to overcome the bad condition to like ubuntu as on offline mood in my work zone.Actually i used ubuntu 9.04 for my offline work in Dell. Now also same condition starts. Please help to come internet and enjoy ubuntu.
OS is Ubuntu 10.04. I have HomePNA-connection which is converted to Ethernet by Netsys NH-300 HomePNA-Ethernet adapter.
The problems that I have: Sometimes when I boot I don't get IP from DHCP. If try to ping any address I am told that host is unreachable. Sometimes this I can get IP by using command dhlient -r and dhclient to request new ip. Sometimes only way to get my connection to work is booting the computer.
Sometimes the connection works fine from the start but disconnects later for short time. Sometimes this happens every ten minutes, sometimes less often. If I wait for a while the connection might start working again, if not dhclient -r or reboot helps usually. But not always.
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.
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 installed Ubuntu 9.10 using the default setup (Gnome I think) and on my Gateway Notebook using a wireless connection. It appears to be working great and I can even see my Windows drives and network storage on my home office systems.I have also set it up to run my favorite Bible software on Windows running under VirtualBox. I then installed the KDE Desktop so that I can select either desktop when logging on.
However, once I am in the KDE desktop, I cannot connect to the internet. I have checked and double-checked and the wireless settings seem to be the same on both the Gnom and KDE Desktops but still no network or internet connection when using KDE. I might mention that I am using the 64 Bit version of Ubuntu.
