I am a total Linux n00b. The only progress I've made is all thanks to my room mate, and I think he's tired of helping me with my problems.

I've been running wireless with no problems since I've had Linux set up. However, I wanted to take advantage of a wired connection, and so far it's been impossible to get it to work. It detects the cable when it's connected, starts "Setting network address", and then fails with no error message.


Type:
Wired Ethernet
Connection State:
Setting network address
IP Address:
No IP address.
Connection Speed:
10 MBit/s
System Name:
eth0
MAC Address:
10:9A:DD:44:53:64
Driver:
tg3

I have no idea what I'm doing, and no idea what to do to fix it.

I have Linux kubuntu kde installed on a 2010 iMac 27 inch with dual boot. What's odd is that the ethernet wasn't working with OSX either, but from what I gathered looking into the issue from people with the same problem, it was clearly an issue with OSX. Linux users had referenced ethernet working on the same system when using anything except OSX.

I know my first mistake was purchasing an Apple product, but what can I do now. Maybe it's a simple fix I just don't know about?

Please, help me trouble shoot the issue so I at least know where to begin. Any help is greatly appreciated, thanks.

might be helpful to provide the output of

Code: Select all

lspci -nn |grep ethernet

Is there a DHCP server on the other end of the ethernet cable? If not then it will never work with that configuration. My old notebook uses the tg3 driver and I have never have problems with it.

I don't know what that means. Do I type that in the terminal? What directory do I need to be in? I am lost, sorry.

How would I find that out? I don't even know what a DHCP server is or isn't. If it isn't a DHCP server, which is likely I guess, how would I change the configuration to allow it to work? Please help me out, I'm ready to learn. I don't know a lot, but I'm not stupid.

Thanks for the replies, I didn't realize anyone had bothered, I'll make sure to have notifications set this time around.

just copy and paste it in a terminal, it will display which ethernet chip is installed - might be helpful

in Kmenu -> configure desktop -> network settings -> network connections

look at the wireless tab -> wlan0 -> edit -> IPv4 address tab (might be asked for root password) and compare that to the wired tab -> auto eth0 -> edit -> IPv4 address tab they should be the same, if not change the wired to be same as wireless

A DHCP server is responsible for handing out network configuration information. Your broadband router is usually responsible for handing this out to computers connected to it (using either wired or wireless connections).

If you connect directly to your ISP, then your ISP will be running a DHCP server - although some ISP's require this to be manually configured.
