Adrian Michael Nida has created a patch from Andrew Atrens’ work that will allow a Atheros-based wireless card to work on the current release of DragonFly and use WPA. Andrew Atrens does have some corrections. If you have this hardware, please give it a whirl; as patches for this have been around for a while, and it would be nice to have it in the tree.
A running description of activity related to DragonFly BSD.
Damn! I have this hardware and I have an AP at work that uses WPA, but the problem is the laptop I have with this hardware doesn’t seem to like DragonFlyBSD. It’s a Dell Latitude C600 and after installation it has all these weird IRQ errors and messages. If it wasn’t for that, I’d totally test this. Bummer!
Try without ACPI.
