Internet wont work with ubuntu WIRED CONNECTION
« on: August 14, 2012, 09:58:10 pm »
I installed Ubuntu 11.10 on my Dell Optiplex 745 today. I could not connect to the internet with the LiveCD, but I installed it anyway. It still doesn't work. This is the first time linux has been installed on this computer. Windows XP connects with no problem.

I have a Broadcom NetXtreme 57xx Gigabit Controller.

I have tried removing Network Manager and using dhclient but it doesn't work either.

I also tried

Code: [Select]
modprobe tg3and then

Code: [Select]
dhclient eth0The last command runs forever. I dont know if thats good or bad. when i do

Code: [Select]
ping google.com or try to open a page with firefox, i get a connection error.


lspci output:

EDIT2:
I don't know, maybe i am not running tg3 correctly?
When i run modprobe tg3, it does not run forever. It just finishes with no output. Like this:

Code: [Select]
# modprobe tg3
# _
dhclient loops forever though. Is that OK?

modprobe just loads the module so the computer can use it. It does not run it(I believe)

What you might want to do is try to get an updated version of the driver's .deb installer from a comp with internet and install it with dpkg
I currently don't do much, but I am a developer for a game you should totally try out called AssaultCube Reloaded download here https://assaultcuber.codeplex.com/

As I said, Windows is able to cnnect to the internet. Unfortunately, I cannot find the linux tg3 driver on the internet in .deb format. Maybe it comes with Ubuntu? How can i check to see if i have it installed?

And then, how do I make Ubuntu use it?

Yeah, mine uses the tg3 driver.

So I would do

Code: [Select]
modprobe tg3

and then what?

He has tried to connect via command prompt, since he used dhclient :)

It's very unusual to see wired networking fail to work on Linux. Maybe you're missing some firmware for that card model, or the driver for that particular, outdated version of Ubuntu has a problem ?
Unless you're into the Unity interface (in which case you should use Ubuntu 12.04, as it's somewhat less immature and less buggy in 12.04 than in 11.10), you may want to use Mint: it's very close to Ubuntu, but the Cinnamon desktop environment offers a desktop which feels like, well, a desktop.

Yes, I am using the unity interface. I have Ubuntu 11.10.

However, it looks like my computer may be the problem. I am looking at this right now: http://www.math.ucla.edu/~jimc/documents/optiplex-745.html

Yeah, I am doing everything from terminal because I uninstalled network manager.


EDIT:

I am downloading Ubuntu 12.04 to see if it fixes the problem. It seems that 12.04 has been run on Optiplex 745s before.

EDIT:

If all else fails, I can put arch on it: https://wiki.archlinux.org/index.php/HCL/Desktops/Dell

EDIT:

I booted the Ubuntu 12.04 LiveCD and it still cannot connect to the internet. I did "modprobe tg3" and it didn't seem to do anything. What should I do?
