Internet does not work on a Gigabyte motherboard

thank you for your report

does your ethernet link light on your motherboard light up when you plug in your ethernet cable

can you please execute the following commands and attach in separate files

ifconfig -a

lsmod

also, can you please attach the file /etc/networks/interfaces

in your ethernet cable

answer: yes it lights up, like i said i can even enter in the modem configuration, the ethernet seens to work, i can comunicate with the modem... but the internet does not work (it is a new ubuntu install, completely clean, even in the live cd the internet does not work)

all the files are atached

sorry for my bad english :-)

Do you have other machines on the same local net going thru the dsl modem that can access the internet?

can you paste the contents of your /etc/resolv.conf file here in a comment

yes i have another machine. Actually i have a TpLink router conected in the Dlink 504 router to provide wireless conection to a notebook. I already tried conecting the PC on the TpLink...even shuting down the TpLink... the odd is that when i haved a A8N SLI mobo and a A64 X2 this same modems worked perfectly fine. Since i got my core 2 duo and this new mobo it stoped working.

Open you browser (firefox possibly)
clear the Url/Address area at the top of the screen

then enter this address 198.175.96.33 all by itself with nothing else
hit enter

tell me if you get the Intel home page displayed

here what happened when i tried, its funny....it was conecting...but it sttoped to enter and stayed like this. I did a ping on the ip to see what would happen. Here it is...i hope it helps

I dont think they allow pings to that address.

Does the other machine on the Lan have the 192.168.... as its DNS address resolver

do you know about wireshark the ethernet packet tracer

perhaps you could load wireshark and run it to see where things are going

I dont know much about your router is it possible it is set to only forward internet traffic from the windows box?

fixed :D, the problem was that the DSL 500G modem + Ubuntu using IPV6 simply dont work, on windows it uses IPV4, disabling ipv6 i works fine :D. Thanks for the help.

Best regards

the modem was a 504T, my mistake, but the problem was the IPV6.
