I bought the netgear ptv 2000 from Dell shortly after buying my 15z. Since the 8.1 upgrade I haven't been able to connect via widi. I have followed the directions from the Intel website (http://supportkb.intel.com/wireless/wireless-display/templates/selfservice/intelwidi/#portal/1026/ar...), but the wireless display does not appear on the list of devices accessed from the charms menu. (My TV is "dumb/smart"; it is connectable to my wifi network, but it doesn't have any real built-in functionality other than dlna through AllShare - so I need to go through widi for most of my content.) Someone found a rather complicated solution here: https://communities.intel.com/message/218449, but I would prefer a Dell solution. I would think that others have grappled with the same issues in the months since 8.1, but was unable to find them on this board.
