Abstract

The present description provides methods, computer program products, and systems for alternative network communication for access point troubleshooting and monitoring. When a station has difficulty initiating or maintaining a connection with an access point, or even when performance is suboptimal, alternative network communication is initiated. The issue can be handled by reporting to a troubled access point for self-correction, or by uploading interrogation commands or code for active correction externally by a station. Further actions can be taken, for example, when a station determines through alternative communication that a troubled access point itself has connection issues to a back end network, the station uses a different access point for reporting up to a network admin. Although Wi-Fi and Bluetooth are described herein, other combinations of wireless protocols are implementable.

Claims (30)

1. A computer-implemented method, in an access point in a Wi-Fi communications network, of using alternative networks for troubleshooting or monitoring, the method comprising the steps of:

providing access for at least one station over a Wi-Fi channel to connect with a wired backbone network;

detecting a triggering event indicative of a communication issue associated with Wi-Fi communications of the access point;

responsive to the triggering event detection, establishing a Bluetooth channel for communication with the at least one station for collecting data associated with the triggering event by actively interrogating the access point to find a solution;

detecting an end to the triggering event;

responsive to the triggering event end, deactivating the Bluetooth channel and resuming access for the at least one station over the Wi-Fi channel.

2. The method of claim 1 , further comprising:

reporting the collected data concerning the triggering event to a controller.

3. The method of claim 1 , further comprising:

receiving RSSI values responsive to the interrogation.

4. The method of claim 1 , wherein: the triggering event detection is initially determined by the at least one station which notifies the access point through the Bluetooth channel.

5. The method of claim 1 , wherein the triggering event comprises at least one of: a link failure, failure of the at least one station, failure of the access point, powering down, sleep mode, network congestion, long flight times for packets, processor load, memory shortage, and processing load.

6. The method of claim 1 , further comprising:

utilizing the Bluetooth channel for communications between an external network and the at least one station, during the triggering event.

7. The method of claim 1 , wherein the access point comprises at least one Wi-Fi radio and at least one Bluetooth radio.

8. The method of claim 1 , wherein the triggering event comprises suspicious activity and the Bluetooth channel is activated to discretely communicate the suspicious activity without alerting the source of the suspicious activity.

9. A non-transitory computer-readable medium storing source code that, when executed by a processor, performs a method in an access point in a Wi-Fi communications network, of using alternative networks for troubleshooting or monitoring, the method comprising the steps of:

providing access for at least one station over a Wi-Fi channel to connect with a wired backbone network;

detect triggering event indicative of a communication issue associated with Wi-Fi communications of the access point;

responsive to the triggering event detection, establishing a Bluetooth channel for communication with the at least one station for collecting data associated with the triggering event by actively interrogating the access point to find a solution;

detecting an end to the triggering event;

responsive to the triggering event end, deactivating the Bluetooth channel and resuming access for the at least one station over the Wi-Fi channel.

10. An access point in a Wi-Fi communications network, of using alternative networks for troubleshooting or monitoring, the access point comprising:

a processor; and

a memory coupled to the processor, storing a BT application to:

provide access for at least one station over a Wi-Fi channel to connect with a wired backbone network;

detect triggering event indicative of a communication issue associated with Wi-Fi communications of the access point;

responsive to the triggering event detection, establish a Bluetooth channel for communication with the at least one station for collecting data associated with the triggering event by actively interrogating the access point to find a solution;

detect an end to the triggering event; and

responsive to the triggering event end, deactivate the Bluetooth channel and resume access for the at least one station over the Wi-Fi channel.
