Network/Internet Connection Problem

[Mlcloud]

My internet is not working. I believe I skipped the particular section of the installation regarding modem and network card devices, and I have no connection whatsoever.

My network card is detected by both lspci and lshw, but dhclient refuses to set up any connection whatsoever. I get a "no broadcast interface found" when using dhclient.

I am on a DSL modem. I do not have a username or password (so I can't use pppoeconf and those other point-to-point things...)

Ifconfig does not list my eth0...

I'm stuck. Can someone prod me into the right direction? I'm using a Broadcom NetXtreme Gigabit Ethernet card, a DSL modem, living in Korea (not sure if that might cause a few differences).

Re: Network/Internet Connection Problem

What about ("doing as root does", of course) System Settings > Network Settings > Network Connections? There, you should be able to set the interface up ...

Re: Network/Internet Connection Problem

Oh, right. That. It shows nothing. I'm not sure what's supposed to be in it, but theres nothing there I can really alter

Edit:
One person (who has never used kubuntu before, but other distro's) suggested a modprobe to insert a module of my network card (I think that's what he said?) into the kernal so that Kubuntu recognizes the card.... What about that?

Re: Network/Internet Connection Problem

The interface in question (e.g. eth0) is supposed to show up there, assumedly as being "disabled" or the like - but if there is no interface listed at all, then you are in trouble ...

As for the idea about adding some kernel modules: there I can only guess, I am afraid - but maybe sudo modprobe -v pci_hotplug would help you on (?).

Re: Network/Internet Connection Problem

Thats... no good. Is there anything I can do? Does anyone have any idea what the problem might be?

Edit: Will do.

Edit2: I don't think it did anything. Checked the connection and settings but nothing had changed.

Re: Network/Internet Connection Problem

And what happens when you try to (re-) start the network, e.g. by sudo /etc/init.d/networking restart, afterwards?

Re: Network/Internet Connection Problem

"There is already a pid file /var/run/dhclient.eth0.pid with pid 134993416"
eth0: error while getting interface: no such device
(repeat above line)
bind socket to interface - no such device."

Re: Network/Internet Connection Problem

O.k. then - would you please show me / us the output resulting from [sudo] lspci | grep Ethernet then? In order to (hopefully) identify the proper kernel module for your specific device, we need the exact name of it ...

Re: Network/Internet Connection Problem

is encryption turned off and/or MAC address filtering turned off on your wireless router/access point ?

Re: Network/Internet Connection Problem

The result of sudo lspci |grep Ethernet -

02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (Rev 11)

And no, I do not have a wireless or a router so I'm not sure if I can answer those questions

Re: Network/Internet Connection Problem

Mlcloud,

having done some additional research on this, I (for now ) would suggest to give the "tg3" module a try:

sudo modprobe -v tg3
sudo /etc/init.d/networking restart

Re: Network/Internet Connection Problem

Hehe, nice timing. Thats what I just found out too.

Edit: Still couldn't detect anything... maybe I need the driver for linux (tg3)?

Here are a series of links that I've found, but can't understand (due to lack of linux experience, coding experience, etc)

http://savannah.gnu.org/bugs/?11555 - site discussing a patch to add support for the Broadcom 5751 card.

http://mail-index.netbsd.org/tech-ke...0/22/0003.html - Someone who had made his 5751 card work?

http://www.linux-tested.com/results/...ton_5700G.html - to quote,

The On-Board Broadcom 5751 Lan chip weren't detected by normal install , must get driver file bcm5700-7.3.5.tar.gz then setup it.

So it looks like my network card is the main problem, and that other linux users have suffered from it... Wow thats unlucky.
