Ubuntu :: System Refuses To Connect To The Network / Internet
Jun 1, 2010
So I've recently installed Kubuntu 10.04, and after the first and second runs, the system refuses to connect to the network/internet. I'm not sure why this is, or how to fix it. It shows up in ifconfig, but other than that I'm at a loss. The Knetworkmanager applet says "Disabled" when I hover over it, and no connection can be made to the internet (apt, Firefox). I'm running x86, with a Biostar T5XE mainboard (Realtek RTL8168D/8111D network chipset). The logs don't seem to indicate a problem, though I could be wrong. The connection is known good: it connected before, but it won't now.
I installed a fresh Debian Desktop without the LAN cable connected. After that I got message when I put the cable in:
Code: Select allNetwork Interface Connection New Wired Connection failed
I have tried to re-install everything once again with the cable in, but during the Debian installation there was no network detected.
However, I proceeded and re-installed Debian. But the problem persists. It continues to re-connect and than disconnect. There is a symbol showing re-connection. The network eth0 is visible to the machine.
I booted Mint Live disc and the same happens there.
As i describe the thread,i won't be able to configure my NIC to connect to internet which is basically done by just running system-config-network in shell to configure xDSL connection.But instead of system-config-network it contains system-config-network-tui which is used for ISDN connection.And after running system-config-network as well as system-config-network-tui it shows the same output which is in attach file
After some google search it shows that there is bug with system-config-network and it is fixed in system-config-network-1.6.0.el6.2-1.el6 but i wont be able to find it.
I am a user or consumer of Knoppix 5.1 and Knoppix 6.2, I see in 6.2 version a very usefully tool, an icon in task bar thats help my internet connection in auto, even if I use a mobile modem like Huawei E160, I only select a 'Auto Mobile Broadband (GSM) connection' and, voila, internet is active. Into version 5.1 don't exist this option. I need to find packages like network-manager.... and all relatives and install in 5.1 in correct order to success.
I dual boot windows xp and ubuntu 10.04 LTS and the wireless card works perfectly fine in xp so I know its not a hardware/network issue. In ubuntu, it detects wireless networks, will connect to network and work for about 20 seconds.
[Code]....
and it continues on after this alternating between a normal 20ms and high ping over 200ms. The connection refuses to load anything off the internet/local network.
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 installed Suse 11.2 on clean HD. I cannot connect to the internet. Seems like Suse didn't install drivers for on board ethernet card. It is a Marvell Yukon 88E8056. I'm new to this and don't know how to install the drivers.
the thing is that I cant use Network Manager to connect to Internet, because it simply do not connect. The connection, although, awailable throught yast when i choose "traditional method with ifup", so everything is just fine, but if i need to reconnect, i have to reboot. How do I setup a !working! connection through Network Manager, or maybe i do not do something properly.
I'm using Ubuntu 10.10 installed in Dell Vostro.Now I like to connect & use internet from my mobile (Samsung C5212) to my lappy.What is the way to do it??
I am a first time Linux user and have recently installed Linux Mint onto my dell inspiron 1525. When i connect the Ethernet cable to my computer the two computers symbol in the bottom right hand corner starts searching for a connection, but unfortunately does not find one. it says "no network connection". one thing that is strange to me but might not be to you is that i have installed fedora 12, 10, and 6, and all distros had the same exact problem. i take the cable out of the laptop with Linux and put it back in my desktop with xp pro and it works fine.also my wireless 1395 card isn't recognized but thats an entirely different pain in the *** ill work on one problem at a time..
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 am relatively new at Linux and am having some problems with an install of openSUSE 11.2. I installed 11.2 on my Thinkpad X31 dual boot with WinXP. It seems to work very well except the network. I looked up swerdna's instructions on setting network cards up. I used YaST to try and set the system up as described in swerdna's instructions. Everything looks fine my network card and wireless card show up in the overview settings screen and everything sets up fine. But when I exit YaST the network doest show up no icon in the system tray and it doesn't even try to connect.
I did go into hardware to see if it was identifying my hardware and my network card shows up as "Thinkpad R40" and the wireless shows up as Cisco Aironet Wireless 802.11b. As far as I know this is correct. I have tried three other distro's and this one has gotten the closest to working so far.
I recently installed Crunchbang Linux on my Eee PC 1005HA. My problem is that i can not connect to the internet. My wireless does not work and wired connection does not work either. I've read a lot of other things and nothing has helped. Any replies would be awesome.
When using Fedora in VMWare, sometimes I can connect to the internet and sometimes I cannot. I do nothing differently on different days. I restart the machine and / or shut the machine down at the end of the day. When the machine starts back up the next time, I might have an internet connection or I might not have an internet connection. The 2 computer symbol that appears in the top will also sometimes be displayed. If I have that icon and click on it, it will display connections I can use including a sys one. I have a bridged connection chosen in VMWare also. Furthermore, when I click on the System -> Administration -> Network Device Control, 'eth0' is listed and it is listed as 'active'.
Yesterday I could ping out to a specific ip address on our network ( 192.168.1.xxx ). Now, I cannot ping that same ip address. I receive an error 'Destination host unreachable'.
How can I make it so that I have the internet connection every time I start up the machine? What do I need to check as far as the internet connection goes and the network connection?
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?
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 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 have a fresh install of ubuntu. I am trying to load some new packages but I think I need internet connection. The issue is I cannot connect to the internet I think I need to setup a network package so I can connect to the internet? This is the first time I have used linux.
I recently removed Windows from a family member's laptop (Gateway NV52) and installed Ubuntu on it. I started out with Ubuntu 10.04 since it was an LTS. She's been very happy with it until a few days ago when it started acting up and refused to load almost any site she frequently visited. I decided to back up her data and do a fresh install of Ubuntu 10.10 (64bit) which is what I use. It installed fine, wireless works seamlessly as well.
However, Facebook refuses to load on any web browser (chrome, firefox, minefield, midori, etc.). It's only Facebook as well. The login page will appear but it will absolutely not login. I've tried it with several different accounts and it just flat out refuses.y other site loads fine and fast, and logs in fine, but facebook just doesn't seem to load.I really do not want to have to move her back to windows 7 as she's prone to viruses and Ubuntu is just flat out awesome at virtually everything, but for her, social networking is her primary way of connecting to friends and it's critical for her to have access to that site. It's really her make or break feature, and if Ubuntu can't do it then she doesn't want anything to do with it.
I've looked everywhere for a solution to this. I've tried changing DNS servers, disabling and re-enabling the wifi, clearing the cache and cookies, even down to resetting the router we use, all to no avail. The site loads fine on every other PC regardless of the OS, and I've run out of places to look.My experience with the Ubuntu community has been top notch so far, and I'm not shy of any terminal work that may be needed, nor am I shy of fiddling with anything.
I Have Installed Ubuntu 10.04 according to the steps mentioned in the following pdf [URL] the problem is after installation i am unable to connect to internet. i have connected internet on LAN but cannot detect it on console. unless i update the system i cannot get GUI.
I have had a heck of a time trying to get my laptop running ubuntu to connect to my home network. I have managed to get it to work at my university which would seemingly be more difficult than getting it to work at home, so I know for a fact it isn't a hardware or driver issue. If I try to connect via ethernet cable from my router, it detects that I connected the cable but says "disconnected" and never lets me connect. If I SKIP the router and go from my modem directly to my laptop via ethernet cable it works great.
Using the wireless network tool I can see all of the wireless connections in my area. When I go to connect to my network it prompts me for the WEP key and when I enter it and hit connect it just keeps cycling and eventually times out and finally again prompts me for my WEP key. I know this network works as it works just fine on my Windows 7 partition. Another interesting note - both my wireless and ethernet connections both worked flawlessly and stoopid easily on the live cd but don't after the full install.
If I manually enter in the information for my wireless through IPv4 settings and enter in the Address,Netmask and gateway I can connect to my network - but then I have no active internet connection. Same deal with my wired connection. Is this because choosing this manual method grays out the DHCP?
2 days ago I did a fresh install of Fedora on my computer to be dual-booted with Linux Mint. The first time I did this install a few weeks ago, I did all of the updates, rebooted (internet still fine) and when I rebooted again, Fedora could no longer connect to the internet (but could still see the networks and ostensibly connect to them). I fixed it then by manually setting the BSSID/IP/DNS/etc.
And this happened again on the new install! This time it took out the internet connection in Mint too. I tried manually setting the connection settings, but that didn't even work for a while. So, last night, thinking that the install might be the problem, I reinstalled Fedora. This morning I finally got my internet to connect on Mint, but I'm concerned that if I do all of the updates on Fedora I'm just going to end up back at square one with zero internet connection.
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.
So here is what I am trying to do. I want to connect my Open Suse 11 machine to the internet. I am almost there.
1. I configured my network card and eth0 is up.
2. I configured my DSL with user name and password and I am authenticated.
3. An IP address is assigned to me and the DNS servers are retrieved.
However I cannot ping or visit any website I use the YAST automatic configuration and kinternet to connect. Here are the gritty details
[Code]...
I do see that kinternet has trouble reading /etc/resolv.conf. It says 'permission denied' although read permissions are set on both /sbin/route and the path that it links to. This should not matter however since the existing entries are already there and valid. I also tried to turn off the firewall suspecting it could be a problem.
So I am being authenticated successfully ( verified with the logs ); assigned an IP; the route seems ok; firewall seems ok. But I cannot browse or do internet things I have been tweaking settings for 3 days now and all seems in vain. Do enlighten me on what I am doing wrong. I bet its something silly that I overlooked. I have had success configuring the same thing in red hat linux and browsing the internet without trouble. Is there something OpenSuse specific that I am missing ?
since installing opensuse 11.2 KDE, is that I can connect to the local resources when I'm not connected via the pptp vpn to the Internet but as soon as I establish an Internet connection, I cannot. Under Windows and other distros I've tried, this has never been an issue, usually I can connect to either local or Internet resources, interchangeably. In a nutshell, I don't know how to troubleshoot this.
