Hi,
This start happening some time ago, I was hoping for a fix but nothing changed (I am now on version 4.0.18.0). Every time when I connect to my Netgear PTV2000 I get asked for the security code. I use Windows 7 x64. I think this start happening with version 3.5.x or something don't remember exactly, but for sure it was not there on beginning when I got the adapter. If I remember well the initial firmware (and WiDi version) just asked for a 4 digit code, once and I did not have to enter it anymore after. After one of the updates which includes also a firmware update the code changed is more digits and each time I connect I need to enter. I reseted Netger to factory settings uninstalled and reinstalled the WiFi, WiDi software and drivers but to no effect. So what is the fix ? Just don't tell me that this is a feature and is by design. This alone almost kills WiDi for me (it's faster to plug an HDMI cable than to key code each time). Thank you.
