I have a HP elitebook 8730w (win xp pro SP3) with intel AGN 5300 wireless. At home I have a problem connecting to a wireless network.
When it tries to acquire an adress through DHCP it fails. My router logs an DHCP offer but never recieves an ACK. Giving it a fixed address solves the problem.
I turned on tracing in Windows and in the EAPOL.log i see the following error:
 21:13:26:187: EAPOLQueryGUIDNCSState: Intel(R) WiFi Link 5300 AGN - Packet Scheduler Miniport is in PSK Mode Returning S_OK
 21:13:31:140: ElTimeoutCallbackRoutine entered
 21:13:31:140: WPA exchange not secured within 5 seconds in AUTHENTICATED state
 21:13:31:140: EAPOL Failure: Fail Count = 3
I already updated to the latest drivers without avail.
I have some more info, it seems that the windows firewall blocks DHCP .
I tried adding an exception for ports UDP 67 and 68 but it still keeps blocking the traffic.
Its only for my wireless connection. The wired connection has no problem with DHCP.
