Acer Aspire 4530 Driver

That's the problem with machines running new hardware and drivers...I don't think drivers are available yet, you should wait and download the latest distro of ubuntu and see if they have implemented compatibility withe the drivers...do you have the latest one, 8.04.1?

Before you do anything I suggest you to read this guides, I hope they'll help you:
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx/
https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper

Anyway if your network device is a Broadcom you could try using "ndiswrapper" to try and use wndows xp drivers on ubuntu (for wifi device). try downloading the drivers for windows xp (from acer website,I think you'll have to search a little bit 'cause they offer a lot for vista, anyway they should be available)
So install ndiswrapper, then extract the drivers and locate the .INF file
-> then from the terminal go to the file (for example if it's in the Desktop/drivers folder you'll type cd /home/yourname/Desktop/drivers)
-> then type sudo ndiswrapper -i INF
-> at this point the drivers should be installed.
-> for wifi, you need to set it to let GNOME Network Manager use the drivers, so open the file /etc/modprobe.d/blacklist (sudo gedit /etc/modprobe.d/blacklist) and add a line on the bottom like this: blacklist bcm43xx
then open the file /etc/modules (sudo gedit /etc/modules) and add a line at the bottom like this: ndiswrapper

Hope for the best!:)
