(This is not an answer, just something to try and help the next person!) The wireless chipsets used in these are all re-branded. I don't know what the original chipset are (yet). This will be using the "Acer InviLink Nplify 802.11b/g/n" or the "Acer InviLink 802.11b/g" – Oli Oct 15 '11 at 19:26
Yeah, this is a re-branded Atheros chip, ti should have full support on Ubuntu by now. – Bruno Pereira Oct 15 '11 at 19:31

You need to have your computer connected to the Internet for this, use a wired connection, because this will download the correct drivers and install them.

Look for "Additional Drivers" in your dash, open it, there should be your wifi card driver listed there, click and activate it.

Very, very true! Fixed information. – Bruno Pereira Oct 15 '11 at 19:31

I have an Acer Aspire 5755G too. It has a Broadcom BCM43227 WiFi card. I recommend you to take a look here:

Follow the steps if yours has the same card. I think it will help you to get it to work.
