Ubuntu Installation :: Network Connection Detected - Internet Not Working?
Aug 17, 2011
i installed a linux flavor (Ubuntu 10.04 LTS, Ubuntu 11.04, and then Linux Mint).. They all gave this same problem about the wired network (see the picture). The connection seems to be fine but i can't connect to internet or even to my router. Which is weird since it knows my router IP 192.168.1.79. Wasted the whole night trying to figure it out but i just can't understand why. I have a separate partition on this computer to run Win7 also and confirmed that the network connection is working.

I've installed opensuse 11.2 on an old IBM thinkpad. The install went without a hitch and when I got to the desktop I inserted my Dlink DWL-G132 wireless USB adapter. Opensuse immediately recognised that a wireless device was attached and I could see my wireless network listed. I entered my WPA password and was able to connect to my routers configuration page by entering 192.168.0.1 in the URL bar of firefox. For some reason I am unable to navigate to any webpage. When I enter a URL firefox acts as though there is no internet connection. The only way I can get the internet on my laptop is to connect it to my router with a cable. I used a wired connection and ran the update utility thinking that perhaps an update would fix the issue but it did not. I know the adapter works because the laptop used to have windows xp installed and I could connect fine with that.
Does anyone here have any idea why I would be able to connect wirelessly to the routers configuration page but not to the internet? I appreciate any advice anyone may have.

I just set up my computer to dual boot Windows XP Home and Fedora 10. After installation, on Windows, the internet works just fine (since I'm able to compose this message). However, the internet connection on Fedora does not work.
Here are the details:
I'm connected via a cable modem only.
I have an Ethernet cable connecting my modem and PC.
I've tried looking info up online about the issue and many people say to do an ifconfig -a to get the MAC Address and so forth. How to get the connection working to use the internet with Fedora?

I need to setup an Ubuntu Server to handle backups over the network (probably rsync over ssh). That server will then transfer the backup data offsite over a secondary external data line.How can I configure the ethernet interfaces to handle such a scenario?

I'm running the newest version of Ubuntu on a usb while I have a hard drive problem with win7. Internet problem is that I'm using a D-link N USB adapter to connect- it recognises my home network, even looks like it's connected, but nothing happening.

I have just installed openSuse 11.2, but my network connection isn't working. I'm new to linux so i don't know how to approach this problem and how to diagnose what's the problem. Few information about my system: I have Asus X51L laptop with KDE installed. I have cable internet wired to laptop via ethernet network card. In Windows XP my connection is working without problems, but in Suse I have problemsThe main problem is when I enter Suse PC light (on modem) is not working, and it should blink (at least in Windows does). Cable and power light is turned on, and that's good.

The router IP is 192.168.1.1. 1 windows laptop that work wireless and wired. 1 debian desktop that work wired and not working wireless. THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:
[code]....
I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.

OpenSuse 11.4 Asus Netbook 1000H Following other members in the forums I have installed Opensuse 11.4 on the Netbook. In the early days Ubuntu Netbook Remix worked well for me. But this has been discarded, and the "one size fits all" Ubuntu had become slow and cumbersome. So..... onto my post. Opensuse is working well. The install went beautifully.
It detected the Wireless Internet and I am able to get on line. I also need to share the Internet connection to a desktop. This is done via a small network switch. Thus far I cannot do this. I tried to use ifup to configure a static ip but this busted my Wireless configuration. I went back to knetwork manager. Then I tried to set up the wired network using knetwork manager and under IPV4 "share" the connection. But this blanks out any possiblity of a static address and substitutes dhcp. My desktop cannot ping the this dhcp address. Ubuntu had this thing called Firestarter? - from memory. This configured the system to sharing the network.

I'm new in SUSE 11.4. My problem is: I'm using Alfa AWUS036H card. It's recognised and I can establish connection to my network, but cant get to Internet. I can't surf the web cos Firefox tell me that connection is timed out. Now I'm confused why I can't surf the web even if I'm connected. Also, I trayed to instal linux drivers for this card folloving Ubuntu "how to" and it just dont work.

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:
eth0
Link encap:Ethernet HWaddr 001:aa0:91:a7:51
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets: 0 errors: 0 dropped: 0 overruns: 0 carrier: 0
collisons: 0 txqueulen: 1000
RX bytes: 0 (0.0 B) TX bytes: 0 (0.0 B)
[Code]...
If I comment out "auto eth0" as well, it makes no difference. If I uncomment both lines ("auto eth0" and "iface eth0 inet dhcp") then I lose the internet connection altogether.

I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.
I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?

So I recently installed Red Hat 5.5, I'm able to access the internal network, including viewing pages on the intranet (however they load very slow, perhaps an unrelated issue). I can see that RedHat is properly resolving IP addresses, it just times out when it tries to connect to them.
route:
Destination Gateway Genmask Flags Met Ref Use Iface
15.28.184.0 * 255.255.248.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default (hostname of 15.28.184.0) 0.0.0.0 UG 0 0 0 eth0

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.

I recently installed KDE in my ubuntu machine. I would like to try it out for a few weeks at least, but networking is not working at all.
I somehow managed to find the network settings and it shows no connections, wired or wireless. When I log out and log back in with gnome, my wireless gets connected automatically.

I'm using a WUSB54GC network adapter to connect to my home wireless network. My network was not visible, so I added it and it shows connected, but when I launch the browser, I can't get a connection. I'm using Ubuntu 10.4. All other computers on the network connect fine and I disabled my firewall to see if that made a difference.

I am working on a cross-platform application for Linux ,Apple and Windows, so I have a full tower system with four SATA hard drives that be selected with a switch, so that I can change drives and operating systems at will. -sort of makes me a jack of linux systems, but master of none.It's important to mention this, because it shows the strangeness of the problem as it is isolated to Debian* systems.
So where does debian/ubuntu get it's information to establish a network connection?How do I rectify the problem? I can hardly blame the hardware (RTL8111B), because the problem is isolated to Debian systems.

It is just 3 days that I am using Linux Opensuse 11.2. I got a problem with Internet connection: I have HUWAEI E1550 3G Modem, but I have no idea about using it on Linux OpenSuse 11.2. Now I use it Windows7, there is no problem, because there is a program and driver for modem.

I have bought a TV which has possibility to connect via LAN to Internet. At this moment I have no router but I suppose it should work also via PC where is 2nd net card. (of course PC must be ON)
So I connect TV to PC to one net card and from 2nd to internet (provider socket). But how should I set the PC to work it? Allow both cards, it is clear but is it enough? I dont suppose
PS: if important, KDE and oS 11.3

I'm trying to setup network server for a week now and I was able to setup network in which i can ping the other workstation that is connected to my switch which is also connected to my server and I can also ping the server from local workstation.
I have 2 NIC, I use eth0 to dial to my dsl connection(ppp0 has the IP of my internet) and I use eth1 to connect to the switch and use to connect to the other local workstation
Now my problem is I don't know how can I share the internet connection from my eth0 or the ppp0 to my eth1 to the network, what do I need to be able to share the internet connection to the workstation that is connected to my switch.

I am attempting to connect Ubuntu 9.10 to the Internet.I have a network connection, and Karmic detects it fine. I can ping addresses within our network (e.g. the Windows computer in the next room), and I can ping the router, but if I ping, say www.google.com, it says "Destination Net Unreachable". Previously, in Jaunty, I had a similar problem.I found a workaround: launch Pidgin. Somehow, launching Pidgin temporarily edits my configuration. However, in Karmic, I have no access to Pidgin, however, and Empathy does not do the same thing. Since I have no Internet, I cannot "sudo apt-get install" anything.How can I get the Internet working?

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.

Ever since my BT Hub 2 has updated a few weeks ago I'm unable to connect to the internet either wireless or wired. I duel boot on my netbook with xp and duel boot my desktop PC with windows 7. None of the Ubuntu�s are able to connect, I have no problems with the windows side of things.
Has anyone any ideas on how to fix this until BT decide to fix the problem. Preferably a step to step guide as I have limited experience with Ubuntu. I�m using Ubuntu 11.04.
