A method includes identifying multiple statistics associated with each of multiple wireless connections. The multiple wireless connections form a single communication path between two wireless nodes in a wireless network. The method also includes identifying an overall quality associated with the communication path using the statistics. The method can also include assigning a quality value to each statistic for each wireless connection, where the overall quality is based on at least one of the quality values assigned to the statistics (such as a lowest of the quality values). The statistics could include a Received Signal Quality Indicator (RSQI), a Received Signal Strength Indication (RSSI), and a transmit success/fail ratio. The quality value assigned to each statistic could include a 'good' quality, a 'fair' quality, or a &#x201c;poor&#x201d; quality.

Apparatus and method for reporting of communication path quality within a wireless network

A method includes synchronizing a first gateway with information from a second gateway. The second gateway operates in a primary role with at least one primary network address. The second gateway communicates with at least one wireless device that uses at least one encryption key during at least one secure communication session. The information includes the at least one encryption key. The method also includes detecting a switchover event at the first gateway. The method further includes, in response to detecting the switchover event, switching the first gateway to the primary role, communicating using the at least one primary network address, and maintaining the at least one secure communication session at the first gateway after the first gateway switches to the primary role.
