The Atherosclerosis stuff is WiFi.

What does this command show?

If it doesn't show much, you are lacking the proper driver, or your hardware is knackered.

The "operation not permitted" message you report for the command "modprobe atl1c" would indicate you need to be root to do that so preface the command with sudo and try again. It looks like you are using an older, possibly unsupported version of Ubuntu so has internet connection worked previously?

Hello and welcome to the forum

Per yancek's suggestion below, the command for Ubuntu should be...

From the list mentioned here, it appears you're using Ubuntu 10.04, which, depending on the age of your system, may or may not have all the necessary drivers to run (use) your devices. Please share with us the brand and model (and model number) of your computer so we can give you more detailed information. Thanks!

Please also bear in mind that Ubuntu 10.04 has already reached its EOL (end of life) and is no longer receiving security and other siftware updates.

Regards...

my network card can be connected to Internet when using windows 7 in the same computer with different hard disk (it work under windows 7). but it does not work in my current ubuntu.
how to do next because it show:
lijian@ubuntu:~$ lspci -v |grep -C5 eth0
lijian@ubuntu:~$

yes, it has internet connection worked previously. it does not work now (it work under windows 7) but WiFi is ok.

the command show:
lijian@ubuntu:~$ sudo modprobe atl1c
[sudo] password for lijian:
lijian@ubuntu:~$

when input command lsmod, some message disappear and some below:

Hi...

I would need to know your computer brand and model (and model number) to see if the latest version of Ubuntu would be a "good fit" for your system.

Also, did the ethernet connection work at any point in time with your current Ubuntu install?

Regards...

You have no driver loaded for your network card.

the ethernet connection worked WITH current Ubuntu install half month ago but sometime no good and sometime good.

I DO NEED UPGRADING AND ALSO NEED TO GET THE CARD WORKED AT CURRENT INSTALL.

will you give me commands? I AM NEWBIE AND I DON'T QUITE UNDERSTAND THE MOST OF COMMANDS

Hi...

In using all caps in some of your words, you're essentially shouting at us. While I understand your situation may be difficult, please understand that we are all volunteers here and no one is paying us to provide technical support nor are we required to do so. Please remain civil in your discourse.

At this point, I have no idea why your ethernet has stopped working in your current install of Ubuntu. Did you do anything during this time that would affect the networking in your OS, such as attempting to upgrade the driver or installing and uninstalling network related software? If so, please tell, us exactly what you did.

Considering you only have 2 GB's of memory, you might want to add more memory to your system. According to what I see here, if this is your system, you should be able add a total of 8 GB's, which would help prevent sluggishness with the more resource intensive distributions.

If that's not a possibility and you want to stick with something in the Ubuntu family, you can try installing Lubuntu 16.04 LTS, which is more lightweight than the current version of Ubuntu. You can view the step by step installation instructions here. Please read the information carefully to ensure you understand what's required. You can run it live first (before installing it) to see if you like it.

Regards...

That's not a very recent kernel is it?

it is old one which i cannot get rid of because i built some server on it.
my computer does not give indication on whether I press the cap button. i am lazy not to rebuild everything

thank you for your advice.
for "In using all caps"(i added the original paragraph at different time),i say sorry to all because my careless keying and my limited English knowledge(so i ignore the difference in meaning between upper-case and lower-case）lead misunderstanding.

for my cable card connection, it is usually sudden disconnection during my normal Internet browsing. i didn't change software at that time.

for "add more memory...", do i have to insert mem chip?

the message "...configuration: autonegotiation=on broadcast=yes driver=ATL1C driverversion=1.0.1.14..." give "ATL1C" instead "ATL1E",does this mean some contradiction? can i solve it ?

if i install Lubuntu 16.04 LTS, do i have to erase my current system?
