Ubuntu Networking :: Cannot Connect To The Internet - Time Out On "connecting To ..."
Nov 11, 2010
I have an Ubuntu 10.10 (64 bit on a Dell PowerEdge T310) that cannot connect to the Internet. The network interfaces work fine because I can connect to our local network and to the firewall appliance. The network is controlled via DHCP. I have another Ubuntu 10.10 machine that connects to the internet without any issues, so I don't believe that it is a firewall issue.
Via networking tools, I am able to perform a lookup, so DNS appears to be working. When I perform a trace route, it makes it to my firewall and then returns "no reply" from there. In firefox, I time out on "connecting to ..." I also fail on any apt-get update calls. I've disabled ipv6 in Firefox with no effect. Ifconfig results and gateway route is all correct.

I'm connecting to my wireless, but I can't connect to the Internet, not even via an IP address.
(*) Can not open web pages via IP address.
(*) Can ping internal hardware no problem.
(*) I can connect to the Internet via Ethernet no problem.
(*) I used to be able to connect via wireless on this computer. No settings changed in the interim.
(*) Several other computers currently connected & accessing Internet via the same wireless - no problem.
(*) Based on other posts, I disabled the avahi daemon, but this had no effect.
Outputs of some commands:

I have an old desktop computer that I installed Ubuntu 10.04 on. I also have a laptop with Windows 7 Pro which is connected wirelessly to the internet. The desktop does not have a wireless card and the modem is in another room. I have a spare ethernet cable, is it possible to connect the Ubuntu desktop to the internet by connecting it to the laptop with the cable? I'm not very good with computers.If this isn't possible, how would I go about connecting the desktop to the internet?

I have a wireless Internet modem (USB) and a LAN Ethernet connection. I can only pick 1 of them to connect to (by disconnecting the other). How can I connect to both at the same time?

I have 2 pcs at home. I dont have a switch so I can connect only one PC at a time to my adsl router/modem for internet access. In the past I had successfully connected the two PCs (NIC to NIC) to each other using the same ethernet cable which was supplied with my dlink adsl modem.
Recently the motherboard of on of my PC went bad so I replaced it with a new one. The problem is when I connect the two using the same Ethernet cable they won't connect. The lights on the Ethernet port won't light up. I can still connect both of them to the adsl router (NIC to Router) (one at a time).

I just installed Ubuntu 9.10 and its great. However when I connect to the internet at home it shows that the connection has been established but I still cant connect to the internet. My flatmates are all able to connect. However, I am able to connect from work both wirelessly and through an ethernet cable.

I have 2 network cards in my computer, and I would like to connect them to 2 different networks. Both connections work fine when I use them so that the other one is unplugged, but as soon as I connect the second plug (doesn't matter which one is first) they both stop working.I've been googling and reading dozens of pages about how to set this up, but I still can't figure it out.
One connection gets its addresses from DHCP and that connection is used for pretty much everything. The other connection has a static IP, and is used to access just one other computer, which is in the same subnet as that static IP.I'm using Ubuntu and I've been using the NetworkManager Applet to manage my connections. If I've understood my googling correctly, NetworkManager Applet can't be used alone for this kind of setup, is that correct? (Even though it has that "Routes..." button and "Use this connection only for resources on its network" which I've tried for the connection with the static IP, but they don't seem to help.)
So my questions are:
1. So I really can't use NetworkManager Applet for this?
2. What software / tools should I use instead? (My googling brought up such wildly different solutions, and I don't know which ones are outdated, if any.)
3. Should I get rid of NetworkManager Applet completely?
I'm familiar with routing in theory, totally clueless about the networking tools in Linux, but happy to read manuals and happy to learn to use the command line versions if anyone can point me to the right direction.

I would like to my laptop to connect to two networks at the same time.The first network is wireless through which I access the Internet.The other network is a wired router to which my laptop and another computer are connected. would like to connect to the two networks at the same time so I can access the Internet, and talk to the other computer on the wired lan.My problem right now that I can only connect to one network at a time. Even the act of plugging in the cable for the wired network causes the wireless to cease functioning.Could somebody give specific steps. I am on Ubuntu 11.04.

I noticed that it takes a couple more seconds before Ubuntu connects to my wireless network when it wakes up from sleep. I didn't have this annoyance when I was using 10.04, and only appeared when I upgraded to 10.10. It takes about 5-7 seconds before it indicates that it's connecting. When I was using 10.04, it only took a maximum of 2 seconds for it to indicate that it's in the process of connecting to my network.

I would like to connect a PC (it has no white IP) through Internet. It's possible to create tunnel with SSH, but I need more easy way. May be there is some service exists (like TeamViewer), so people can just run simple command on that PC?

I have a problem which is connecting automatically to my spwireless. On my windows, my schools provide me the disc which contains several .cer files and a automated batch files to copy the .cer files to the root folders. I can choose to use the other network but in using that, i have to manually connect compared to using the spwireless. Anyway, my problem is that, how do i add the .cer files and to where so when i connect to the network it will look there for the cert. Because when i manually connect, only one cer can be chosen.

I'm on a LAN of 3 computers connected with a router.The router takes one wire as input from the modem(cable).

Sometimes I am unable to connect to my WEP network in ubuntu. No matter how many times I try, even restarting, it will not allow me to connect. However if I boot into XP, I can connect to the network. Then when I reboot again and then try in Ubuntu again, it will work.
Router is a Netgear MR814v2

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 had an ubuntu 10.4 box, I used it mainly for programming, virtualization & other stuff. I've installed this box about 1 month ago, working on it everyday. About 2 days ago problem appeared when I just opened up firefox for cheking my E-Mail. I typed : [URL]. & nothing appeared & I just seen the famous firefox page when a networking problem is around . I just wondered and checked the connectivity & the wire itself, but find no problem around them, while playing with firefox I just had a turned on virtualBox machine (Windows XP service Pack 3), I just checked the internet within vm & working fine, I checked my e-mail from vm (windows xp), I thought restarting the system might help to solve the problem but damn, problem didn't solved & still arounds Well, I searched through websites dedicated to linux networking & forums that might help, I did anything that faced to my brain , follow another people recipes but problem did't solved for about 3 days ! Playing with primary & alternative dns didn't help, I did my best about solving the problem, disabling ipv6 from both linux networking settings & firefox itself didn't help also . After that, I thought reinstalling the linux might help to solving the problem, but install a new version of ubuntu, 10.10, I tried it, install it but the holyshit problem still arounds ! I think this might be a bug on ubuntu distro, I tried Mint 10 & the same problem, reinstalling x64 version of fedora core & the same problem .It's interesting that the same settings for TD-8101G TP-Link working fine for my Windows XP, Windows 7 x64 & the problem is arounds just for my linux distros .As I said I checked the internet for the problem & found nothing workable for me. I thought it's better to describe the problem & maybe another people faced with that problem .

I have a CentOS server that I can connect to over my local network. The computer I'm currently on is on that same network and can access the internet. My server can not connect to the internet. The network card is obviously connecting to the network since I can access the server locally with SSH or HTTP. While in the terminal for the server, I type wget google.com and the server can not find the specified host, so this leaves me to believe it can not access the internet.

I have an AWL6075 Golden N Wireless Mini USB Adapter from Airlink, and I'm running Ubuntu 9.10. (Kernel 2.6.31-20-generic) I've learned that in order to get this to work, I needed to download this firmware update: http://launchpadlibrarian.net/373876...8192sfw.bin.gz and copy it into /lib/firmware.I have also needed to download and install the drivers at http://www.filestube.com/f76673d157e2ab6203ea/go.htmlI've even Edited my connection to make it available to all users.This is great, and it gets my internet running. Unfortunately, I seem to have to make the module, and insmod the module 8712u.ko everytime I boot up. I know I had it set in 9.04 to be able to do this on boot up, but in 9.04 I didn't have to re-make it everytime.

I had installed Ubuntu 10.04 yesterday. When I see the network tab, it shows it is connected to the web via eth0. I could download all the packages for updates.But when I try to connect to internet via Firefox, or by evolution or other software,I am unable to connect.The configuration of the ethernet card is proper as I checked that via terminal window.It is a peculiar problem, where I can download update pakages but unable to connect via browser or email client.when I ping to ubuntu.com is shows it is healthy and successful.I have a Acer dual core laptop, and connect to internet via wired lan .

I setup a network bridge on pc A, with windows 7 installed on it, using windows default bridging tool. I connected computer B to computer A and Im trying to connect to the internet through the network bridge on computer A. Computer B (client) has two OS's installed, win XP and linux(tried with different distributions, didnt work). On windows XP everything is working, when i try to ping the router (after computer A) it also responds. On linux system nothing is working, and im not quite sure why.
I set up linux to receive IP adress from DHCP, which is router in this case (behind computer A), same way windows XP was configured. I decided to ask here, because I couldn't find anything on the net. My guess is windows-made bridge supports only windows-OS's but that would be kind of strange (its just a software bridge).
