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:~$

to: yancek
 

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.

to: ardvark71
 

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?

to:JeremyBoden
 

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

to : ardvark71
 

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?

Thank you for your explanation, all is fine. :shake:

Hmmm. Could you post the results of the following command...

It's rather unusual for a device to stop working in this manner by itself (software related,) so I'm wondering if there might be some other issue, such as a piece of hardware. Also, if you would, please run a S.M.A.R.T. test using this information and post a screenshot of the readout.

Yes, either by adding additional modules or swapping out (trading) the existing modules for ones that have a larger amount of memory. Please see an example here.

I'm not sure at this point, perhaps another member can comment. Maybe that's something I can research here after a while, Lord willing.

No, you should be able to keep your current install and be able to choose which one you log into at boot. However, I can't guarantee it will be a seamless process, problems may or may not occur.

Regards...

for "so I'm wondering if there might be some other issue, such as a piece of hardware. Also, if you would, please run a S.M.A.R.T. test using this information and post a screenshot of the readout.":

yes, there are some other issues but they should not be related to cable connection to Internet because the cable connection is good when i change to another hard disk installed windows 7 (in this case,it seems ok for every aspects on this computer).

on my current ubuntu system, it always give alarm: one or more disks are failing.
but it can continue working as long as i turn on the computer. the attachment is the screen shot of the computer before i run self test.

Hi...

Let me make sure I understand this correctly. Are you dual booting both Ubuntu and Windows 7 from the same hard drive (the Toshiba MK3265GSX) or is each OS installed on a separate drive? The Toshiba drive appears to be failing and will need to be replaced.

The issue can easily be related as bad sectors effect the OS and other software on the drive and may be affecting the drivers for your ethernet device.

Just to be on the safe side, I would highly encourage you to back up everything you want to save to a USB thumb drive as quickly as possible!!

Regards...

REPLACE YOUR DISK!!!!!

You have thousands of bad sectors, according to that SMART attachment.
Certainly, take a full backup as a matter of urgency.

to:ardvark71
 

yes, it is dual system on the same disk and the windows system has booting problem. (by the way,i have another spare disk installed windowsn7. it run good for Internet,which means the adapter is ok)
but under ubuntu system, the alarm of disk arose almost at the beginning time i bought the computer. this has been for several years since then. the bad sectors developed very slow? can i install the card driver again on good sectors to fix the connection issue under ubuntu? and i do not know how to re-install the driver for cable connection to Internet. for "give "ATL1C" instead "ATL1E"", what can i do to find more information?

thank you
 

thank you. will you tell me how to do to avoid more bad sectors coming?

You cannot fix or repair the disk.
Replace the disk with a new one.
Consider whether do take a copy of your disk or whether to to do a re-install of the OS.

Keep an eye on the bad sector count - a few dozen is OK, but if it increases substantially over a few weeks, its probably time to scrap the disk.

Hi...

Ok, thank you. If you intend to use the spare hard drive on a regular basis, I would check with Microsoft to make sure you use of that copy of Windows 7 is legal for use on this particular system. ;)

That's possible. However, to confirm that the hard drive is indeed failing, you should use another diagnostic utility. Seagate Seatools should be able to scan your drive, as it normally supports other brands of hard drives. Download the .iso file and then burn it as an image to a CD using a CD/DVD burning application. Please post the results.

I'm not sure how you would do that. If the drive is indeed failing, it wouldn't be worth the time anyway. It would be be best just to back up everything you want to keep and replace the drive as soon as possible. ;)

Regards...

to:ardvark71
 

i don't mean to use the spare hard drive on a regular basis. that is just for test usage which tell me the computer's card adaptor is functional (in hardware aspect). the term "driver" i use indicate card's software which i hope to rebuild on the card adaptor. i don't mean hard disk driver. thank you a lot.

to: JeremyBoden
 

it is good reminder. thank you

Hi...

Thank you for the clarification. :)

I knew what you were referring to. However, as I mentioned, if the hard drive is failing (and accumulating bad sectors,) this would be a pointless endeavor. Please run the utility I mentioned above and post the results.

You're welcome :)

Regards...
