I found the problem my end, basically when you access the pineapple from via your network and the Wan/Lan port on the pineapple installing infusions fails with the symptoms discussed above. If you connect via the PoE Lan port however and the 72.16.42.1:1471/ interface then all works as it should. Not sure why we can't install and control the pineapples full feature set from a dhcp assigned ip on the Wan/Lan port. Cheers, Jay
