Ubuntu :: Acer Revo Internet Access Not

Its been a few years since I gave linux a go but having just bought an acer revo and enjoyed xbmc on myxbox I thought I would give it another go.I downloaded the 64 bit version to usb stick and got to the desktop of the live install.Everything looks great but no internet access over both wireless and ethernet.I'm used to the wireless being detected etc in windows and even though I found what must be the network manager and put in my 64 bit wep code etc it couldn't find my wireless connnection.

I thought then that mabey the preinstall ubuntu doesn't do internet.Just to see if this was the case tried it with the netbook version on this I can get ethernet access but on removing network cable no access at all.I've got an old netgear router which I am replacing soon in case thats the problem.I don't want to install ubuntu unless I can get wireless internet/network access.Being a total linux newb some of the guides I've tried to follow on the net presume I have too much knowledge.So I end up getting lost.I go into wireless connections psecify name of network (SSID ie Wireless) put in the Mac code of my router and the 64bit WEP key. I don't touch the lpv4 and 6 settings as don't know what they do Still no joy

I wonder if anyone out there has a revo 64 bit version of ubuntu working and could help mme find my wireless connection.Just an update I reput the settings into the netowrk manager and it worked although very slow.Is this because its a live install. I'll now try it with ubuntu 64 bit and see if I can get access...I seem to be getting there although very slow
