Is "Set up a new network wizard" is any way related to native Wi-Fi driver? RRS feed

  • Question

  • Hi!

    Can anyone explain the purpose of "Set up a new network wizard"? (Control Panel -> Network and Internet -> Network and Sharing Center -> Setup a new Connection or Network -> Setup a New Network (Configure a new router or access point)). Is it any way related to native Wi-Fi driver?

    Is it used to configure WPS on wireless Routers?

    Can anyone provide the links which helps in understanding this query?

    Thanks in Advance...

  • The new network wizard can use WPS to configure a wireless router. It will use either UPNP or EAP transports.  If using the UPNP transport, it might not use the Wi-Fi driver at all (the AP might be connected by an Ethernet cable).  However, if there is no layer-3 connection to the AP, then Windows cannot use UPNP, and Windows will only use EAP.  The EAP transport does make use of some special features of the Wi-Fi driver.

  • The New network wizard helps to connect the PC on which it runs, to a router which is already configured. It does not configure the router. Of course, the station driver plays a significant role in this process: it will be called to scan, connect, and so on.

  • Hi!

    Thanks for your reply...

    What are the special features that wifi driver makes use in case of EAP (can you elaborate on that...)?

    can you give the links corresponds to it, which helps to include these special features in the wifi driver?

  • WPS requires these "unusual" features from the WLAN NIC. ("Unusual" meaning that you might not see these features being exercised much otherwise):

    * The WLAN NIC must include two copies of the WPS IE when scanning.  This is requirement Device.Network.WLAN.Base.SupportSeparateBeaconAndProbeIE.

    * The WLAN NIC should be careful about flushing the BSS list during scan and connect operations.  In particular, Microsoft's WPS implementation (particularly on Windows 7) may choose to make several connections in quick succession.  If the BSS list is completely flushed after the first connection, the NIC might fail the second connection because it doesn't recognize the target BSS.

    * The WLAN NIC must permit the EAP authentication used by WPS.  (I haven't seen this be a problem for WLAN NICs as much as APs).

    In any case, the best way to excercise your NIC's WPS implementation is to use the HCK, which has several tests for the above.
