Troubleshooting link and protocol in a wireless network
Methods, apparatuses, and systems directed to facilitating troubleshooting wireless connectivity issues in a wireless network. In accordance with one embodiment of the present invention, either a diagnostic supplicant in the wireless client or a diagnostic manager initiates a troubleshooting protocol between the diagnostic supplicant and the diagnostic manager over a diagnostic link in response to one or more events. In one embodiment, after the diagnostic supplicant establishes a link to a diagnostic manager via a diagnostic link, the diagnostic supplicant generates and transmits a problem report to the diagnostic manager. The problem report initiates a troubleshooting protocol between the diagnostic manager and the diagnostic supplicant.
1. A diagnostic apparatus comprising:
one or more processors;
a memory;
a network interface;
a diagnostic management application, physically stored in the memory, comprising instructions operable to cause the one or more processors to:
exchange diagnostic data with one or more wireless clients over a diagnostic link established in response to a failed attempt by at least one of the wireless clients to establish connectivity to a wireless network;
based on the diagnostic data, transmit a radio frequency (RF) measurement data request to the one or more wireless clients and to one or more tangible elements in a wireless network;
receive first RF measurement data generated by the one or more wireless clients;
receive second RF measurement data generated by the one or more tangible elements in the wireless network, wherein the first RF measurement data is different from the second RF measurement data; and
transmit diagnostic information to the wireless clients based on the first and second RF measurement data.
2. The diagnostic apparatus of claim 1 wherein the diagnostic link is implemented as at least one of a wired connection, a physical channel, a multiplex channel, an existing WLAN channel, and peer channel.
3. The diagnostic apparatus of claim 1 wherein the diagnostic apparatus generates and transmits a completion report to the one or more wireless clients, wherein the completion report provides at least one of results from a troubleshooting protocol and a recommendation.
4. In a diagnostic apparatus, a method comprising:
exchanging diagnostic data with one or more wireless clients over a diagnostic link established in response to a failed attempt by at least one of the wireless clients to establish connectivity to a wireless network;
based on the diagnostic data, transmitting a radio frequency (RF) measurement data request to the one or more wireless clients and to one or more tangible elements in a wireless network;
receiving first RF measurement data generated by the one or more wireless clients;
receiving second RF measurement data generated by the one or more tangible elements in the wireless network, wherein the first RF measurement data is different from the second RF measurement data; and
transmitting diagnostic information to the wireless clients based on the first RF measurement data and the second RF measurement data.
5. The method of claim 4 further comprising transmitting a request of a diagnostic client to perform one or more diagnostic tests.
6. The method of claim 4 wherein the diagnostic link is implemented as at least one of a wired connection, a physical channel, a multiplex channel, an existing WLAN channel, and peer channel.
7. The method of claim 4 wherein the diagnostic apparatus generates and transmits a completion report to the one or more wireless clients, wherein the completion report provides at least one of results from a troubleshooting protocol and a recommendation.
8. A diagnostic apparatus comprising:
means for exchanging diagnostic data with one or more wireless clients over a diagnostic link established in response to a failed attempt by at least one of the wireless clients to establish connectivity to a wireless network;
means for transmitting, based on the diagnostic data, a radio frequency (RF) measurement data request to the one or more wireless clients and to one or more tangible elements in a wireless network;
means for receiving first RF measurement data generated by the one or more wireless clients;
means for receiving second RF measurement data generated by the one or more tangible elements in the wireless network, wherein the first RF measurement data is different from the second RF measurement data; and
means for transmitting diagnostic information to the wireless clients based on the first and second RF measurement data diagnostic tests.
