In deep without a paddle help

[Maccapacca]

Errrr bought an Acer Revo to replace the useless Boxee Box and all's well it works buuuuuuuuuuut the auction showed Windows 7 logo on the advert so assumed it came with something I know.

Well it's come with Ubuntu which is totally new to me, sounds daft, flicking around seems ok and I'll get the hang of it in time however it won't connect to the internet, have connected it to a wired connection which works with my other laptop and also connected it to my wireless which shows a connection but again it's not working.

Using a standard SKY Sagem router

Am a bit stuck please help

Thanks tried all that after sudo su it asks for [passord for tsc3] then whatever I type just says "sorry try again"

ifconfig shows

eth0 with an ip addy
lo with an ip addy
wlan0 with an ip addy

with a host of other info

If I enter dhclient eth0 I get "RTNETLINK answers: operation not permitted

Might try W8 if I can get the software from my laptop to the Revo

Thanks for your help ended up pulling W8 off the web then making a boot USB, now running lovely on W8 if a bit jerky on Love Film.
