Ran across this thread while trying to find out if a wireless dongle I was considering would work with my Raspberry Pi Kodi. I took this advice and bought an airport express.
I don't recommend this. My Kodi now has access over it's ethernet port to my wifi, but I cannot connect to the Kodi device since it's hidden behind the aiport express on an isolated network. It looks pretty, but my one and only apply product purchase is so far pretty disappointing.
