Abstract

A method for troubleshooting and resolving access point device uplink failures. The method includes detecting an unresponsive access point on a wired computer network. In addition, the method includes retrieving a record of peer access points to determine the peer access points for the unresponsive access point. Further, the method proceeds to sending a first request to a peer access point of the unresponsive access point to query the unresponsive access point for a response over a wireless network. In response to the query, the network management system sends a notification that the unresponsive access point has a cable malfunction if the unresponsive access point responds to the query. Furthermore, the method includes, in response to the query, sending a notification to the network management system to inform that the unresponsive access point has a power malfunction if the unresponsive access point fails to respond to the query.

First claim

What is claimed is:

1. A method for troubleshooting uplink failures, comprising:
detecting an unresponsive access point to a network management system on a wired computer network;
sending a first request to a peer access point of the unresponsive access point to query the unresponsive access point for a response over a wireless network, in response to the query:
sending a first notification that the unresponsive access point has a cable malfunction if the unresponsive access point responds to the query, and
sending a second notification that the unresponsive access point has a power malfunction if the unresponsive access point fails to respond to the query;

sending a second request to the peer access point to service a request from at least one of a plurality of client devices of the unresponsive access point.

2. The method of claim 1 , wherein the power malfunction comprises a power failure.

3. The method of claim 1 , wherein the cable malfunction comprises a loose uplink cable.

4. The method of claim 1 , wherein the query comprises a ping.

5. The method of claim 1 , further comprising retrieving a record of peer access points to identify the peer devices assigned to the unresponsive access point.

6. The method of claim 1 , further comprising assigning priorities to each of the plurality of client devices of the unresponsive access point.

7. The method of claim 6 , wherein in response to the query, sending a third notification that a gateway device which connects the unresponsive access point to the network management system has malfunctioned.

8. The method of claim 1 , wherein the wireless network comprises at least one of a 802.11 protocol and a Bluetooth network protocol.

9. The method of claim 1 , wherein the unresponsive access point is detected by the network management system hosted in a network cloud.
