ubuntu 10.04 destroyed my NIC


Hi. I have just installed ubuntu 10.04, and when I tried to connect to the network, the DHCP failed. I configured the IP manually but the laptop couldn't connect to the network. I looked over the internet to find a solution, but rather I found a lot of people having the same problem, but this time they say that the NIC don't work now even in windows. when I checked windows I found that is true. the network card is corrupted. It does'nt work any more. is there any solution to this problem.?
the laptop is TOSHIBA satellite pro U400 with marvel yukun NIC

NB.
the strangest thing is that pinging the laptop from the other devices on the network, after configuring the laptop with static IP, succeed. but ping other devices on the network from the laptop doesn't work.

NB
I was a big fan of ubuntu, but not any more.


Please help me.

Are you using Ubuntu or Fedora? Also, how did you configure manually? What tools are you using to configure? You have not provided enough information for anyone to even guess at a solution, and the information you did provide is conflicting.

Yeah, I am curious whether this is really Ubuntu 10.04 or Fedora 9 or some hybrid mix of the two. Or maybe a dual-boot?

Try completely pulling the battery from the laptop and leave it out for several minutes. An ability, even if not enabled, to have network packet cause the system to "power on" could leave the NIC and a few other parts enabled enough for the controller and/or BIOS code to be checking on this all the time, preventing the NIC from going to a cold reset state.

I used to have fedora, but lately I switched to ubuntu. I used Ubuntu 10.04 Desktop edition. I meant by configuring it manually is to use
Quote:
ifconfig eth0 192.168.0.2 netmask 255.255.255.0
the command went successful but the laptop can't communicate with the network. Till that time I thought that it is a little problem that can be fixed. but the first article I read is about some one has the same problem and said that the problem continues even after removing Ubuntu. the time I read this, I switched to windows 7 (I have two operating systems on my laptop) and I found that the NIC is not working any more. the fact that problem is extended to reach the windows make me think that it is a hardware failure resulted from a bad driver.

I am not a professional but I am not newbie also. can you explain why this happened and not just to me.

the symptoms are that the DHCP fail. assigning the address with ifconfig doesn't solve the problem, as the device can't use the network either. I tried to ping another device on the network from my laptop and result is that no thing appear on the screen, not even time out message and when I press ctrl+c to end the ping command, they say that number of packets what sent and all of them got lost. then I pinged the laptop from another device on the network and the ping success which I find completely strange.
my NIC type is marvell yukun.
during the installation, nothing strange happened. I used the default options.
could you help me please

Boot to a live cd of some other version and try it.

Ping is a poor choice as it is more and more becoming a blocked by default protocol.

I had a network problem and I thought it was because of ubuntu. the reason that I thought the problem is because of ubuntu is that I checked the Internet and I stumbled upon a link for a guy claiming the same thing. but this doesn't deny the fact that I am so stupid. I wish I could delete this post. Sorry. and thanks brucehinrichs, Skaperen and jefro. sorry for wasting you time.
and by the way, the new Ubutnu is awesome

Glad to help, and glad your problem is solved! No apologies necessary, I learned something new from this myself, thus making the time spent worthwhile. Definitely not a waste.

Unable to get network connection

I have a desktop PC running Ubuntu 10.04 and I am unable to receive a network connection. I have a Windows XP PC that is connecting as well as a laptop running Ubuntu 10.04 on wireless that connections. The network cables are plugged and tight. What can I check to find the problem?

Not sure what fixed your issue another 1 but glad it is fixed.

You didn't ask anything stupid and you didn't waste any time. We all are trying to learn. Keep asking. Some day you can try to help others. That is when you will really feel stupid. hehehe
