Ubuntu Networking :: Cannot Connect To Internet After Using Windows
Apr 28, 2010
I have a dual booted Windows XP and Ubuntu 9.10 box and have an unusual problem in that after connecting to the internet on Windows I cannot connect using Ubuntu. I don't believe it is actually a problem with configuring my Ubuntu connections because when I get up in the morning Ubuntu connects without any problem - this problem only exists (and persists for at least several hours) if I try to connect immediately after connecting on Windows. I don't know how long the problem lasts because I usually get so ***ed off I just go to bed and then in the morning I can connect. As I have recently been forced to change my ISP due to moving house, is it possibly a problem with my provider's service and not a Ubuntu problem at? I have a second Ubuntu 9.10 box which I have to manually connect [URL] which does connect even when the dual booted one won't.
im installing Windows 7 and CentOS 5.5 on my computer..but, since i installed centOS, my windows can no longer connect to the internet. i already diagnosed and it said that my ethernet/LAN cable didnt connect (the error message is "plug an ethernet cable into this computer") although i've already checked that it is properly connected and when i see the ethernet port behind my PC, the LED indicator is on.However, when I switch to CentOS, the internet is working fine.
My friend is trying to share his clearwire connection with me using Windows ICS. Using network-manager or wicd, I am unable to connect to his share. I am able to connect unencrypted with iwconfig, to the ad-hoc network, and then use dhclient to gain ip address.
I am not able to connect to WPA encrypted share using network-manager or wicd. nm-applet crashes when trying to connect. I am attempting to setup wpa_supplicant, but haven't got it working yet.As usual, the wireless networking out of the box experience in Ubuntu doesn't work. This is extremely frustrating. If Ubunut's goals are to be the default desktop, then these guys need to get wifi that "Just Works"...
I installed Ubuntu (10.04) today and it has gone smoothly except for the fact that I can't connect to the Internet when in Ubuntu (connection works fine in Windows XP). I am using a wireless USB card (Linksys WUSB600N) to connect.
The weird thing is that the card detects all the local networks, asks me for a password to my network, and it even says it is connected to my network after I put the password in -- but when I open Firefox no pages will load.
There is another weird quirk as well: Ubuntu will not restart or shut down properly (it hangs around indefinitely with the little white / orange dots going across the screen) unless I first remove the wireless card from the USB slot. But that doesn't bother me as badly as the lack of Internet.
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 have a dual boot laptop. It has both Ubuntu 10.10 and Windows 7 running on the same machine. Windows can connect to the wireless flawlessly, however, Ubuntu seems to be so fuzzy. The first time, it can connect to the wireless internet in the dormitory. The succeeding days, the network icon just keeps on turning as if it's trying to connect. What's wrong? Is it because of the drivers? If that's the case, then why are there times when I can connect to the wireless internet?
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.
I'm running Ubuntu 10.04 inside VMware Player running under Windows Vista and I can't connect to the internet or the host computer from the Ubuntu.
I have set all the VMware services to manual (like VMware DHCP Service), but starting them manually doesn't help.
In VMware, the network seems to work (there is a green dot beside the network icon) and I have tried both Bridged and NAT settings.
ifconfig doesn't show the eth1 interface, unless I give it as a parameter (or use -a). I think this means that Ubuntu thinks that the network isn't connected at all.
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.
I have a fresh install of CentOS 5.5. I am trying to browse to the Windows machines on my network (Places > Network Servers > Windows Network), but I get a blank window. I am able to ping the Windows machines using their IP address, but not by their name. What do I need to do to be able to see the Windows machines and also to connect to shared folders on these machines? So far I have tried starting SMB (via System > Administration > Server Settings > Services). I have also tried changing my smb workgroup to "WORKGROUP" (the default was mygroup which did not match my Windows machines.
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.
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.
