Mine is an Aspire 5570Z. I tried 8.04 and 8.10. I couldn’t get the wireless
network to work. I worked on it for a few days and then gave up.

I installed Mandriva 2009. Everything worked for a while. It went unstable,
I reloaded Mandriva again. No wireless this time.

You should Google “Acer Aspire 7720 ubuntu”. There is a lot of info. It
looks like that isn’t an issue on that model.
