If I were to download and build the source code for Haiku (the most recent), would there be support for WPA wireless encryption?
this feature is not yet available , but Axel Dörfler is working on WPA encryption.
you can download official, nightly haiku images or ISOs from here:

No need to build haiku yourself. WPA is not finished yet. I am very sure you will see a news story @ haikuware when done:

Alrighty. I guess I’ll have to wait a while longer.
