Abstract

The system monitors a wireless device, detects when the device has failed or is not operating properly, and is able to remotely reset the device. The device may be reset remotely without a technician required to physically attend to the device. This out of band management allows for quicker, cheaper and more efficient handling of undesired states of a device, such as failure to operate. For a modem, the system may detect that the modem is not broadcasting a signal or is not communicating with the Internet or other network. The reset may be implemented through an access point in communication with the malfunctioning modem. For an access point, the system may detect that the access point is not communicating with a modem or another access point. The reset may be implemented by a neighboring access point or modem.

Claims

1. A method for rebooting a first cable modem by a wireless access point, the method comprising:

detecting, by the wireless access point, a service failure of the first cable modem, in response to not receiving a response, or receiving a failed request message, from the first cable modem to a request sent by the wireless access point;

generating, by the wireless access point, an indication of the service failure of the first cable modem, the indication being adapted for transmission to a management device; and

in response to receiving a reboot command from the management device at the wireless access point, generating a wireless command signal for wireless transmission by the wireless access point, the wireless command signal being adapted to cause the first cable modem to reboot in response to wirelessly receiving the wireless command signal.

2. The method of claim 1, wherein the wireless command signal is adapted for transmission to the first cable modem through a second access point.

3. The method of claim 1, wherein the indication is adapted for transmission to the management device via a second cable modem.

4. The method of claim 1, wherein the indication includes status information of the first cable modem.

5. The method of claim 1, wherein the indication is adapted to be received by an application on the management device, the management device being a wireless device.

6. The method of claim 1, wherein the wireless command signal is adapted for transmission to the first cable modem via a secure communication channel between the wireless access point and the first cable modem.

7. The method of claim 1, wherein the indication is adapted for transmission to the management device via the internet, the management device being a remote server.

8. The method of claim 1, further comprising:

failing over, by the wireless access point, to a second cable modem until the first cable modem resumes operation after rebooting.

9. A non-transitory computer readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for rebooting a first cable modem, the method comprising:

receiving an indication of a service failure of the first cable modem, the indication being received from a wireless access point in communication with the first cable modem, the service failure detected following an absence of a response by the first cable modem to a request sent by the wireless access point; and

generating a reboot command for transmission to the wireless access point, the reboot command being executable by the wireless access point to transmit a wireless command signal to the first cable modem, the wireless command signal being adapted to cause the first cable modem to reboot in response to wirelessly receiving the wireless command signal.

10. The non-transitory computer readable storage medium of claim 9, wherein the reboot command is adapted for transmission to the wireless access point through a second access point.

11. The non-transitory computer readable storage medium of claim 9, wherein the indication is received from the wireless access point via a second cable modem.

12. The non-transitory computer readable storage medium of claim 9, wherein the wireless command signal is adapted for transmission to the first cable modem via a secure communication channel between the wireless access point and the first cable modem.

13. The non-transitory computer readable storage medium of claim 9, wherein the reboot command is adapted for transmission to the wireless access point via the internet.

14. The non-transitory computer readable storage medium of claim 9, wherein the reboot command is executable by the wireless access point to further fail over the wireless access point to a second cable modem until the first cable modem resumes operation after rebooting.

15. A system for rebooting a first cable modem, the system comprising:

a processor;

a memory; and

one or more modules stored in the memory and executable by the processor to;

receive an indication of a service failure of the first cable modem, the indication received from a wireless access point in communication with the first cable modem, the service failure detected following an absence of a response by the first cable modem to a request sent by the wireless access point; and

generate a reboot command for transmission to the wireless access point, the reboot command being executable by the wireless access point to transmit a wireless command signal to the first cable modem, the wireless command signal being adapted to cause the first cable modem to reboot in response to wirelessly receiving the wireless command signal.

16. The system of claim 15, wherein the indication is received from the wireless access point via a second cable modem.

17. The system of claim 15, wherein the reboot command is executable by the wireless access point to further fail over the wireless access point to a second cable modem until the first cable modem resumes operation after rebooting.

18. A method for rebooting a first cable modem by an access point, the method comprising:

detecting a service failure of the first cable modem by the access point;

generating, by the access point, an indication of the service failure of the first cable modem, the indication of the service failure being adapted for transmission to a remote device;

in response to receiving, at the access point, a reboot command from the remote device,

generating a wireless command signal for transmission to the first cable modem, the wireless command signal being adapted to cause the first cable modem to reboot,

failing over, by the access point, to a second cable modem until the first cable modem reboots in response to wirelessly receiving the wireless command signal.

19. The method of claim 18, wherein the indication and the reboot command are adapted for transmission through the second cable modem.

20. The method of claim 18, wherein the remote device is a mobile device and the reboot command is a Wi-Fi compliant signal.
