RELATED APPLICATIONS 
       [0001]    This application is related to U.S. application Ser. No. ______ (Attorney Docket BN01.830US) filed Mar. 15, 2013 and titled “Apparatus for Detecting Incorrect WEP Key For Open Authentication” which is herein incorporated by reference in its entirety. 
     
    
     FIELD OF THE DISCLOSURE 
       [0002]    The present disclosure relates to communications, and more particularly to techniques for detecting incorrect WEP key for open authentication. 
       BACKGROUND 
       [0003]    Electronic devices have many forms of wireless and wired communications to communicate over a network. One example of a network protocol is DHCP (Dynamic Host Configuration Protocol (DHCP) that configures network devices so they can communicate on an IP network. If DHCP is used along with an open key authentication, such as, WEP (Wired Equivalent Privacy), an error may result due to a wrong key and connection to the access point is denied. 
       SUMMARY 
       [0004]    One embodiment of the present invention provides a method for detecting reason for connection attempt failure for DHCP with an Open Key authentication (WEP) protocol. Another embodiment provides an apparatus for detecting reason for connection attempt failure for DHCP with an Open Key authentication (WEP) protocol.

     DETAILED DESCRIPTION 
       [0007]    As previously mentioned, the claimed subject matter facilitates detecting reason for a connection attempt failure. For the sake of clarification, a STA is any device that contains an IEEE 802.11-conformant medium access control (MAC) and physical layer (PHY) interface to the wireless medium (WM). 
         [0008]    In this method, the flowchart depicts a method to facilitate STA to receive transmitted frames. After association, the STA utilizes current WEP key to encrypt and broadcast random challenge. STA does not directly broadcast, but utilizes a unicast packet which an Access Point (AP) decrypts and retransmits over all nodes. 
         [0009]    In an abstract view, a management utility and a detection utility may be used to facilitate detecting incorrect WEP key with open authentication. 
         [0010]    In the flowchart, a block  104 , the managemenet utility is sending command WEP_DETECT_ON to supplicant. The supplicant creates and sends WEP_DETECT with TRUE parameter to the host driver. Host driver switches DETECT_FILTER ON. 
         [0011]    At block  106 , management utility sends a challenge command CHALLENGE_SEND to the supplicant. Also, creating and sending broadcasted data packet with random challenge to the host driver. 
         [0012]    At block  108 , management utility starts WEP_DETECT_TIMER. Consequently, broadcasts WRONG_WEP_KEY and sends command WEP_DECECT_OFF. 
         [0013]    At block  110 , host driver receives broadcast packet with its own MAC address, it checks state of the WEP_DETECT_FILTER and if it ON, host driver sends received packet, if OFF, it drops the packet. 
         [0014]    At block  112 , when the supplicant receives challenge, it notifies framework by sending “WEP-DETECT-OK” event: and turns OFF BN_WEP_DETECT_FILTER by sending WEP_DETECT ioct1 with FALSE parameter to the host driver. 
         [0015]    At block  114 , when Framework receives BN_WEP_DETECT_OK it terminates BN_WEP_DETECT_TIMER.
