A power reduction mechanism in a mobile communications device detects the use of a wrong WEP encryption key in the establishment of a WLAN connection between the mobile device and an access point for both static and dynamic IP WLAN profiles. The power reduction mechanism detects the failure of the mobile device to acquire an IP address for both static and dynamic IP WLAN profiles. This is achieved by monitoring the communications exchange process between the mobile device and the access point. Upon detection of a potential battery draining problem, the mobile device takes one or more power conserving actions.
