trouble getting Network to work

I installed Ubuntu 5.??? and I connect my broadband network to ethernet and I still tells me no internet.  What am I doing wrong?  Do I need to install something else?    I am totally new to Linux.

trouble getting Net(not)work to work

Maybe a stupid question but doing a lot of user-support at work :-)
Are you sure that you have configured your network correctly (IP-address, gateway and so on) ? And what kind of Broadband-Adapter do you have ? Is it a router... ? What IP-address does it have ... ?
Give some more détails. Maybe we could help you out.

trouble getting Net(not) work to work

That was not a stupid question.  I am new to this and I work alot of hours so I figured I would try to do it from work.  Bad mistake.I am not sure that have configured my network correctly.  I have a Motorola SB5100 Surfboard Cable Modem.  I don't have a router.  When I unplug my ethernet from my window base computer and plug it into Linux base computer it just can't find connection.


Try this, it may help and if not the output may help us help you. So many helps, sorry. Firstly try making sure your network card is detected. Go to System -> Administration -> Network Tools and see if your card is there. It should be an additional card to the standard loopback system. If a card is detected then you can try to configure it. Make sure you enable DHCP and make the connection enabled if it isn't. Reboot. Then go to the console and run ifconfig and give us what spews out if your browser still doesn't work.  Equally any info you have on your system or more accurately where the failing is would be a treat. Good luck.


I tried what has been asked and I go into Firefox browser and type in and nothing happens.  It says it can't find it.  I also typed in ifconfig and took a screen dump of what it said.eth0      Link encap:Ethernet  HWaddr 00:E0:18:1F:07:94          inet6 addr: fe80::2e0:18ff:fe1f:794/64 Scope:Link          UP BROADCAST MULTICAST  MTU:1500  Metric:1          RX packets:57 errors:0 dropped:0 overruns:0 frame:0          TX packets:60 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000          RX bytes:24620 (24.0 KiB)  TX bytes:14394 (14.0 KiB)          Interrupt:5 Base address:0x1400lo        Link encap:Local Loopback          inet addr:  Mask:          inet6 addr: ::1/128 Scope:Host          UP LOOPBACK RUNNING  MTU:16436  Metric:1          RX packets:9188 errors:0 dropped:0 overruns:0 frame:0          TX packets:9188 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:0          RX bytes:605657 (591.4 KiB)  TX bytes:605657 (591.4 KiB)


Thanks for that output, sorry my last suggestion didn't help. Is your computer behind a proxy server? If so you will need to configure this for the internet to work. If you still have a windows computer that works you could try manually configuring the network card if DHCP isn't working. You can copy over the IP address and gateway mask from what works in windows into Network Tools in linux. Don't know how much help this will be but it may be worth a try. Sorry...


I copied over the IP address and getway mask from windows and it still doesn't work.  I went into the help to see what to do and not much help there.


OK, just let me repeat what we have. Correct me if I'm wrong.
You have a PC with ONE network-card. This card is activated and configure with the same IP and Gateway like your Win-machine. There is a direct connection between your card and a modem (without router-function). You are not behind a proxy-server.

What you could try - it's only a brainstorming, stupid suggestions may follow ;-)

- Type in the standard-gateway (in the Routing-tab in network-settings). Usually it's you IP-Address but ends with the number 1.

- Type in the broadcast-address (in the network-setting-tab -> configure network -> advanced mode) It should be like your IP but ending with the number 255.

- be sure to try DHCP AND Manually in this tab. Don't forget to de-/reactivate your network-device before trying out new settings.

- be sure to use a SHORT network-cable.

- be sure that your network-device is working correctly. Maybe you can put your 'Windows'-network-device into your Linux-machine to give it a try.

- be sorry for any spelling and grammar-mistakes I made


I got it to work.  I found an IT person at work to help me out.  Thanks.

Same Problem

HiI seem to have the same problem.Can you tell me how your IT person did the settings?Thanks
