Ubuntu Networking :: Unable To Connect To The Network Or The Internet?
Feb 18, 2010
Just purchased a Dell Inspiron 580 MT tower pc with Windows Professional. However unable to connect to the network or the internet when I load a copy of Ubuntu Karmic on dual boot. Windows networking and internet working fine. Is this an ethernet adaptor hardware issue? Broadcom NetXtreme 10/100/1000 Gigabit Ethernet controller-PCI Express card Will try later connecting through a usb ethernet adaptor to see if this is really the problem.
I'm using ubuntu karmic and I'm not able to connect to the internet with my reliance netconnect data card using network manager. Other distros like fedora, opensuse n sabayon connected easily with nm. Ubuntu detects the data card flawlessly but just doesnt connect.This problem has been persistent even in previous ubuntu versions, n I used to use wvdial. But downloading wvdial on some other comp with every dependency is really cumbersome.
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 installed 11.2 on an older HP Laptop which was running XP without any issues. Durring the install, the update processe failed (presumably unble to connect to respository). I am usind a wired connection and the nic is connecting to my router and is recieving an address via DHCP. I am also able to ping the workstion from the router's Web interface. However I am unbale to connect to the internet.I have turned off the Suse firewall via Yast and checked the settings against another computer running ver 11.1 .Everything appears to be correct but no joy.
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've just installed opensuse 11.2 everything is working fine but i'm unable to connect to the internet through my adsl modem the network is shown to be active but after i configure the dsl connection i can't see any option from where to connect
I want to connect my mobile LG Gu285 using data-cable to connect to the internet in OpenSuse 11.3 but the OS is not detecting mobile's usb data modem. I used sudo wvdialconf create command to configure my phone's modem but no modem is detected. I configured bluetooth modem in "rfcomm1" and got success in connection but after a restart I am unable to connect again, throwing error "Modem not found".
Currently I have an Acer Aspire One netbook with Windows XP on it. I want to switch to Ubuntu, so I have the OS on a flash drive and I can run it fine. The only problem is,I cant see any wireless networks in range. I know the router is working because I can connect with Windows fine. A notification also pops up telling me i have to install missing drivers. But when i click on install, the progress gets to 99% and fails. It says i need the Broadcom B43 driver, but i don't know how to get it.
I've been trying for 3 days now, gone to a couple of ubuntu sites, asked some friends who unfortunately don't have the time to assist me, and gone through several forum responses on here to try to find the solution to my problem.The problem is my inability to connect to my wireless network. I have a linksys USB device for my wireless, and the wireless router is literally right next door to my room. I am able to find my router and my neighbor's router from my computer. However I can not connect to my router. It is WPA enabled, and I have the correct password. It is just unable to connect to the network, it tries for a few minutes then doesn't connect at all and says wireless network disconnected. I am currently hooked up to an unsecured wireless network, but I can't connect to the internet. I am using firefox, but it doesn't seem to connect to any site I try.
Here is the lspci

I use Hasee L141 notebook and ever since I installed ubuntu, my internet connection using both wire and wireless does not work but for the windows it works alright. I asked friends to help me but it yielded no result. Is there anything that I'm missing? I re-installed it several times but still had the same problems.Someone please help me. I even tried installing using the wubi.exe but still the same problem.
I have a new laptop with me and I am unable to connect to internet from It. i have a wireless router with WLAN connection. I am able to connect from windows 7 But in ubuntu the network manager doesnt show any WLAN connections at all.. I am a newbie and dont know how to start debugging this Issue. I may like to know,
1. How to ensure that my linux distro has detected network card on my system as the first step
2.Then how to make the wireless connection UP and running.
I have been using Windows XP, and last month i had Linux Mint installed. I was connecting to the internet with an external modem and everything was running fine, until while experimenting with the settings,i bust the whole thing. What i did was to do a "right click" on the 'computer icon' at the bottom right-hand corner to disconnect and from that day i am unable to connect from Linux, but i can still do it under Windows.I had done the same thing under Windows but after going to the 'control panel/network settings' i managed to get the thing working.I went to the 'control panel' in Linux, and under 'network ' i get the message: "Auto eth0 => never". i have been trying to 'edit' the 'settings'
I just switched from Ubuntu to Fedora 13 because I was unable to get Ubuntu to connect to wireless networks. I tried everything suggested in help and forums, and kept getting "Bad Password" with WICD and Network Manager. Now, with Fedora...I still can't connect.
Problem #1: The guide says to "...make sure that the relevant wireless interface (usually eth0 or eth1) is controlled by NetworkManager," and that I do this via: System>Administration>Network
However, there is no Network option under System>Administration.
Problem #2: I open Network Manager, which displays a list of networks. I click on mine, configure it with WPA and the right password, and it fails to connect: "The network connection has been disconnected."
I cant connect to the internet wirelessly or with a RJ45 connection. Last week my son came round and thought it was very call the internet worked fine then. Then he downloaded a programme called wireshark. Since the installation of that programme there has been no internet. Even the internet icon on the top bar has gone Aswell as the network manager section has vanished from the preferences menu. I have uninstalled wireshark thinking it will correct its self but havent had much luck. I am running Ubuntu 10.4 (lucid) Kenel Linux 2.6.32-generic GNOME 2.30.2
I have dual boot system and on windows I am able to connect to wireless but on Ubuntu I am not able to connect to wireless.
I desire to learn to trouble shoot the problem my self hence I would appreciate if some one guides me How to look for the problem. and how to find what is wrong and right
That is why I am not posting any output here but rather would like to learn to solve the problem by myself
I have a multiboot system running several versions of linux which do not all use the same software for handling wifi connections or have the same kernel. They have all stopped being able to connect to the internet in the last few days. My Windows 7 set up still connects though it seems to be a slow to establish a connection.Could BT have changed something and if so what?
I installed Ubuntu 11.04 and am unable to connect to wireless internet. I looked under additional drivers and there doesn't seem to be anything listed there.

The iphone however picks up the network but is unable to connect to the internet.I am running 10.10. Can anyone please help as I have trie dto find a soln to this problem.
I cannot connect to the Internet by LAN. The light of the Internet card is off. On Windows, the system says the cable not plugged while I have plugged it. I solved this by change speed and duplex mode. However, on Ubuntu, the changing doesn't work
I have installed Fedora 10 on my Intel system. I am not able to connect to internet from it. Mine is a broadband connection with ADSL+2 modem. I could connect once but afterwards it was deactivated and I got following bug report.

The server connects fine, I can load pages, FTP in, etc. So everything seems good on that end. When I try to use the internet from the Ubuntu box, however, it doesn't seem to want to connect. The internet won't load through firefox, and attempting to update through the repository won't connect. I've tried playing around with refreshing the connection and rebooting and such, but nothing seems to be fixing this. I can't think of what the issue may be as the connection is working, as I can get on the server, but can't seem to get it to connect outward from the actual box.
I am unable to connect to the Internet in lucid via a proxy server using apt-get or synaptic. Opera & firefox connects to the internet fine with the proxy setting.
I have tried the following solutions:
1) set proxy setting using systems|preferences|network proxy
2) editing ~/.bashrc & /etc/.bashrc
3) creating a /etc/apt/apt.conf file.
4) putting the proxy setting in synaptic
For the proxy setting I have used the both the verbose name as well as the ip address. There is no logon requirements for the proxy server. Either formats work in the browsers.
I have Ubuntu Server 10.10 installed which is guest OS on a XP host. The problem is I cannot connect to the internet. I am using bridged network but still it fails to connect. what configuration should I change in VMWare or should I have to modify anything in XP.
The installation of Ubuntu 9.10 on my HP NC640 worked fine and the network adaptor was successfully recognised: I see the message 'Wired Network Connection 'Auto Eth0' active' and when I open Active Network Connections I see the IP addresses that have been assigned.
However, if I open Firefox, I cannot connect to the internet. I tried pinging some addresses (www.yahoo.com) and that seemed fine. I then tried to run a first system update and Ubuntu seemed to be able to retrieve some packages but not others.
I then tried opening 'Network Connections' and adjusted the MTU (to 1100) and changing the settings of IPv6 (various settings: eg. 'ignore') but none of that seemed to help. Here I wanted to switch off IPv6 but it looks like none of the settings did this. Is there maybe another place where I should be looking? Do I have to do this with the command line? (I hope not) Or can I switch off IPv6 in the system settings? And should MTU be automatic? Or should I set something there?
I just installed Ubuntu 9.10 64 bit on my HP Touchsmart TX2 1020us which has a Broadcom 4322 chip. At first my computer didn't seem to see the card at all, but then I typed the command (sudo apt-get install bcmwl-kernel-source) and then restarted the computer and now I'm connected to the network, but cannot connect to the internet so how do I figure this out. Like I said I have very little experience with linux at all so please don't make your answers too complicated.
I use Windows7 on my laptop. I have got the following version of VMware Server installed on it. **VMware Infrastructure Web Access Version 2.0.0 Build 122589** **VMware Server Version 2.0.0 Build 122956** I am running Fedora Core 10 on VMware, but Fedora is not able to connect to the Internet. However, when I try to ping google.com, it works fine. However, if I try to open google.com in mozilla-firefox, it gets stuck at "Connecting to google.com" and then finally times out. Similarly, yum also gets stuck.

I recently installed Ubuntu 9.10. I was unable to connect to the Internet with Firefox or to download packets using command line or Synaptic Package Manager, or run updates. I disabled IPv6 in Firefox and am now able to browse, but I still cannot connect to repositories, I cannot download packages, I cannot run updates either.
I'm unable to connect to a particular home wireless network under Fedora 9, although I can connect to it using WinXP on the same machine. My Fedora installation is able to connect to my college's unsecured wireless network, so it's not a driver issue I think.It seems to be an authorisation issue, as I'll describe below, but there's one other thing that's bothering me. The SSID for the network I have problems with is for some reason not listed in Network Manager's drop-down list, nor is it in the output of iwlist wlan0 scan. But I'm pretty sure it's not a "hidden" network - I don't know exactly how those work, but I helped the owner of the wifi network in setting it up, and don't remember doing anything that would make it hidden. As far as I can remember, Windows found the network automatically without having to be told the SSID. What's the best way to confirm whether it's a hidden network or not?
Anyway, I try to connect by selecting connect to other wireless network in Network Manager, and entering the SSID. As far as I can tell from the error messages below, the machine does contact the network and attempt to connect, but I'm not authorising myself properly. That may be a completely wrong diagnosis, but hopefully someone can see from the below info whether it's correct or not.I'm not sure which option to use for "Wireless Security": at the time we set up the network, it gave us a Hex WEP key of 26 characters, which is 104 bits. But none of the options in Network Manager's list match that. Here are the options it has, and the error message I get with each one:None - if I select this, it fails to connect, with no error message. WEP 128-bit passphrase - if I select this and attempt to use my 26-character WEP key, it brings up a new dialog, saying "Passwords or encryption keys are required to access the wireless network [SSID]." It has a drop-down box labelled "Wireless Security", but this time the only option is "None", and the connect button is disabled, I can only click cancel. WEP 40/128-bit hex - as above. WEP 40/128-bit ASCII - The connect button is disabled when I try to use the WEP key, as the string is too long. Despite the fact that it says 40/128-bit, it actually accepts 5 and 13-character strings (40 or 104-bit). Since I've got a 104-bit hex key, I tried converting it to ASCII, but it consists of mostly unprintable characters, so I'm not sure there's any way to actually enter it into the textfield. I might have done something wrong here, so I've put my code below to see if anyone can point out a mistake. LEAP - requires a username, not applicable here I think. Windows doesn't need one, and we don't have one from when we set the network up.Dynamic WEP (802.1x) - requires username, private key and various other things, all N/A WPA & WPA2 Personal - Brings up a dialog with the same text as for "128-bit passphrase", but this time "WPA & WPA2 Personal" is the only option in the drop-down list, instead of "None". It asks for a password, so I just enter the hex key again - now it asks for the password for the Gnome Default Keyring, which I don't think I've ever set up. Don't know if I can go any further with that, but my understanding is that since we were given a WEP key when we set up the network, WPA will be N/A.WPA & WPA2 Enterprise - as Dynamic WEP. N/A.Hopefully that's enough info that someone can help diagnose the problem. Some of the behaviour of Network Manager described above doesn't make sense to me, and I'm wondering if it's buggy.
