Asked by johncamel

I am new to Linux. I just installed Ubuntu 7.10. I can't get a wired internet connection.The internet connection works just fine when I start up with WIN XP.
I tried to access the router by entering its ip in firefox. It did not connect. Pinging also failed. My ethernet card is sis900. Please help me to sovle this problem. I ran lshw and ifconfig in terminal. Here is the info i got. I hope this would help. Thank you.

Not sure it will help, but you could try just restarting networking.

sudo /etc/init.d/networking restart

That should force it to try and grab an ip. If that doesn't work, there may be problems with driver support for the nic.

Please edit the file /boot/grub/menu.lst and add apm=off and acpi=noirq to the default kernel parameter

Please open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo gedit /boot/grub/menu.lst

give your user password when requested, you don't see nothing when you type it, then press enter.

Search the row

# defoptions=........ your options

and add the "apm=off and acpi=noirq" parameter

# defoptions=........ your options apm=off acpi=noirq

save and exit

then type:

sudo update-grub

Reboot your pc, then try to shutdown

Hope this help

Please try to disable ipv6 go to Applications->Accessories->Terminal and type

sudo gedit /etc/modprobe.d/aliases

give your user password when requested, you don't see nothing when you type it, then press enter.

Search and change the ipv6 row as below:
alias net-pf-10 off # ipv6
then add this row:
alias ipv6 off

To force not load ipv6 kernel module:

sudo gedit /etc/modprobe.d/blacklist

add this row:
blacklist ipv6

Reboot your pc.

This did not work out. In Network Tools, it shows three network device: loopback interface(lo),eth1,eth1:avahi. I can only configure eth1. When I press configure button for eth1:avahi, it says the interface does not exit. When I configure network setting to DHCP, eth1 becomes unavailable. When I configure network setting to static, eth1 becomes available again with only link speed unavailable.
