3. What is Windows Connect Now ?
A Solution to provision Wi-Fi profiles to Devices

4. Windows Connect Now = Wi-Fi Protected Setup
WCN in Windows Vista
Windows Connect Now = Wi-Fi Protected Setup
To avoid any confusion of where we are now with WCN –
Windows Connect Now is Microsoft’s implementation of Wi-Fi Protected Setup. In fact the Wi-Fi protected setup uses Windows Vista to test out some of the scenarios.

5. Wi-Fi Protected Setup These solutions do not interoperate!
– Windows Connect Now 1.0*
– SecureEZSetup*
– OBC (One Button Configuration)*
These solutions do not interoperate!
Smart Wireless Solutions
– Network in a Box*
Auto Link*
Let us look at Wi-Fi Protected Setup in a little more detail –
There were all these solutions which attempted to make wireless setup easier – Microsoft’s USB Key solution, Secure EZ Setup, AutoLink .. And a host of others. The problem however was they did not work with each other. The only way to easily setup a secure wireless home was to buy all you devices from the same manufacturer … well that is really not a solution.
So in
– A.O.S.S. (AirStation One-Touch Secure System)*
– AutoSecure*
– Quick SETUP buttons*

6. Wi-Fi Protected Setup Simple Configuration Working Group Formed 8/2004
Initial focus is Home WLAN Setup (WPA-Personal)
Strong WFA interest and participation (9 companies submitted 6 proposals)
Wi-Fi alliance formed the Simple Configuration working group. A number of companies were on this working group and came up with the Wi-Fi Protected Setup specification. We have come a long way since then .. today

7. Wi-Fi Protected Setup
Today we have over 250 products that support Wi-Fi Protected Setup.

8. Windows Connect Now Before After
I use this slide .. To show the power of the WPS ..
On the left me trying to set up my Wireless Digital Home without WPS – definitely not a pretty picture .. And on the right is where WPS takes you. Andrea there is setting up here home network, printers, picture frame – no cables, no worries – she gets a consistent experience with every device.
To Dig deeper ..

9. Setting up a Wireless Router
Traditional
Wi-Fi Protected Setup
Un-Box device and Power it up.
Insert CD & start Setup Application
Connect to AP using Windows
Connect cable to the AP
Enter PIN – Proceed through Setup
Run through the Wizard
Connected
Disconnect cable
Let us analyze the steps in setting up a Wireless Router ..
We took about 15 of the top selling APs and analyzed them .. This is what you need to do if you follow the instructions .. 1 2 3 4 5
Since not everyone follows the instructions – they power up the AP and just connect to it .. Leaving their network insecure.
With WPS – we can make this easy and prevent connections from being insecure. Using the model of everyone powers up the AP and connects to it .. The user now sees a Wizard to setup the device ..
That is setting up the AP .. Connection is what people do most frequently

10. Connecting to a Wireless Router
Traditional
Wi-Fi Protected Setup
User attempts to Connect to the Network
User attempt to Connect to the Network
Find Passphrase
Push Button on AP or Enter PIN
Connect using a Cable to the AP & find passphrase
Connected
Disconnect cable
Attempt to Connect, Enter Passphrase 1 2 3 4 5 6
And then there is setting up the device.

13. Setting up a Wireless Device
Traditional
Wi-Fi Protected Setup
Un-Box device and Power Up
Insert CD & Start Application
Locate Device & Connect
Connect cable (USB, Ethernet)
Enter PIN & Proceed
Enter Network Information including Wi-Fi Profile or SSID, Security Settings
Device Connected
Disconnect cable 1 2 3 4 5 6
Once again I’d like to highlight the fact that WPS makes it simple and consistent.

14. Protocol Overview Discovery Mutual Authentication “Enrollee”
Transfer of Wireless Profile
That demo shows us the power of WPS .. Lets look into what is actually happening ..
They way I look at it is that there are 3 phases –
1. Discovery – When you find the device
2. Authentication – You ensure that the device that you are connecting to is yours and yours only ..
3. Transfer of profile .. When you transfer the settings.
It is also valuable to understand how this works in Windows because implementation can be fine tuned to provide a great experience ..

If we go down a level deeper and look at the architecture here is what is looks like ..

Service
You have the Function discovery Subsystem in Vista – which allows you discover most network devices such as UPnP using SSDP , WSD etc. WCN plugs right in here. The FD Provider talk to our service to discovery devices ..
A client app uses FD to see these devices .. Client would be Network Explorer. For configuration it talks to our service. Now our service is not public – and we understand that people may want to write their own client apps – to maybe take some custom actions once the device is on the network.
So ..

20. Extensibility WCN API Set is available.
We introduced some extensibilty …
For discovery – you can use standard FD APIs to get WCN device ..
Once the device is discovered, you can use NetSh commands to configure the Device ..
Lets us look at how simple these are ..

21. Roadmap Windows 7 EAP Transport, Push Button, Vendor Extensibility
WCN introduced. USB Flash Drive.
WCN 2.0 = Wi-Fi Protected Setup.
