I just bought a new Roku Express Plus. I've tried to connect it to my wireless network several times and I get Error code 14.12. I've restarted the Roku Player, restarted my router still not connecting. I have 3 other Roku Players on this wifi network among a few other devices and they all work fine.
Since this is a NEW purchase from Roku, I was surprised that when I went to the support page I was told this product was no longer supported.
