NO CONNECTION AT ALL (wireless, wired) please HELP!!

[vinz++]

hi. i'll make it short.
just did a fresh install of ubu 8.10. with hardy i don't remember having any problem to connect with wire. With intrepid it's being a nightmare.

I have a broadcom wireless card, i need to be connect to get it working, but wired connection doesn't work, only two green balls turning (besides mine), but then a error message. I'm lost.

i post a couple of outputs..
