Linksys AE1000 USB Wireless adapter/(other rt3572usb chipsets)
Does this work in 12.04?
There is an installer for this, it may also work for other wireless adapters with the Ralink rt3572usb chipset.
The installer consists of a shell script and a DEB file. You must configure the DEB, so do not use it by itself. The installer will install the deb.
Download this file Media:Linksys-AE1000-installer.tgz.
Uncompress it, cd into the resulting directory and run install.sh as root.
