Unable to connect to Wired Network

[saurabhgeo]

I have just installed Kubuntu 9.10

Earler I was using Ubuntu 9.04 For some reason I am not able to connect to wired network

Any suggestions ??

[chili555]

Has a driver attached and created an interface? Please open a terminal and post:

sudo lshw -C network
ifconfig 
sudo ethtool eth0

Thanks.

@chili555

thanks for reply

let me tell you what I have tried till now

All problems started with this

http://ubuntuforums.org/showthread.php?t=1431176 my previous thread .

Realising that i cannot make it correct i decidee to reinstall

and then I reinstalled kubuntu .The internet did not worked both the wired and wireless

i thought that i am doing some mistake so reinstalled Kubuntu again since i was not sure of the manual partition where one has to choose tpe of file system i choosed ext4 ...

Now in all this mess i have deleted my windows partition while reinstalling kubuntu second time ,which was working fine even when kubuntu was not working .

The output of the command that you asked me is here below

ethtool eth0

please give me suggestion now i am almost mad i am ubuntu user for more than 1.5 years and now i am feeling so weird whats all is happening ...

[chili555]

Let's see what's happening, or not, under the hood. Please hook up the ethernet cable and post:

dmesg | grep -e eth -e sky

Thanks.

[saurabhgeo]

here is the output of the command you asked for

thanks for you cooperation

This looks like the card was working and connected! Let's try to coax it a bit. Please open a terminal and do:

sudo ifconfig eth0 down
sudo rmmod -f sky2
sudo modprobe sky2 disable_msi=1
sudo ifconfig eth0 up

Does it connect? If so, we can make this permanent.

[saurabhgeo]

when i typed the third command a notification appeared in panel right down saying Network Management attached ...

but it does not connect to internet still ... Should I reboot the system to bring about these changes .

Best Regards

[saurabhgeo]

well i also rebooted but no connection still

[chili555]

Let's create a file:

sudo gedit /etc/modprobe.d/sky2.conf

Substitute nano or kate or vim if you do not have gedit. Add two lines:

alias eth0 sky2
options sky2 disable_msi=1

Proofread, save and close gedit. Reboot. Can you now connect?

[saurabhgeo]

I was just going to try your last suggestion . And hence booted notebook

And guess what

The network is working without implementing last suggestion .

Dude I must thank you for your patience continuing with my post .

Best Regards
