@Rick The virtual miniport should get an IP address from the Intel My WiFi technology software, which includes a DHCP server and DNS. The 192.168.16.* address range sounds correct; that is the default. As I stated previously, the laptop serves as the AP for the Netgear device to connect into so the Netgear should receive an IP in that range from the laptop. There is connection security using WPA, but WiDi sets the key. If you've changed the key on the Intel Wireless PAN profile, you definitely see the problems you're describing.
@Guest You can find the DHCP properties for the WiDi connection in the My Wifi technology UI. You can get to that by pressing the windows key and typing "my wifi"; the application should appear in the selection box. Click "Options" in the upper right and select DHCP tab. It's usually set to 192.168.16.* but yours may be something different. With respect to the wireless driver version, 13.5 should work as well as 14.x. The former is here and the latter should be available on downloadcenter.intel.com.

I would say the cannot obtain network address is a pretty common issue.
Several of my collegues have the adapter - and I am the only one with my adapter left - the other's binned their adapters. All of us have Sony Vaios.
Such a shame - I won't be getting an Netgear product again as I am so disappointed that this product has only worked the first couple of times I used it.
Make sure you have the Intel PROSet/Wireless WiFi driver 13.3 or later installed. Last year some of the Sony systems had a BIOS issue that conflicted with the WiFi driver. This was resolved in the WiFi driver 13.3. Look and see what BIOS version you have. Also laptop make and model number do you have? What is the graphics driver version?
I found the same problems with driver versions right up to 14.2.
There is a new version 14.3 from January 2012 which fixed the problem for me.
This page (works best in IE)
checked my installed Intel drivers and updated the Wifi to the latest version.
The current driver is found here:
After Reinstalling Intel(r) proset/wireless to 14.03 and intel(r)widi to the last version 184.108.40.206, and following the steps you recomended like reseting the computer, the netgear, unblocking the signal, checking the firewall setting I still get the message: "Could not obtain network address... Intel wireless display help".
The only thing that I couldn't find was,( on the firewall): Wireless pan dhcp server. Only can see WiDiapp, and i put check to both
Hello, I have the solution for this issue. "could not obtain network address" .
Okey , all you got to do is go to the my" wifi technology" a panel is going to pop up then go to options and hit DHCP now change the range of the ip address to starting ip 192.168.1.2 ending ip 192.168.1.254 if you are under a class C network.
