Abstract

A method of replacing a first router with a second router within a network may comprise placing the second router in client mode within the network such that the second router is not configured to route network traffic and is configured to search for a network access point provided by the first router. A protocol may then be invoked on the first and second routers, the protocol being configured to enable an exchange of the network name and password information from the first router to the second router in client mode. The second router, in client mode, may be configured according to the obtained network name and password information. The second router may then be switched from client mode back to router mode and enabled to route network traffic on the network. The first router may then be replaced with the second router.

Claims

1. A method of replacing a first router with a second router within a network, comprising:

placing the second router in client mode within the network such that the second router is not configured to route network traffic and is configured to search for a network access point provided by the first router;

invoking a protocol on the first and second routers, the protocol being configured to enable an exchange of at least network name and password information from the first router to the second router in client mode;

configuring the second router in client mode according to the network name and password information obtained from the first router;

switching the second router from client mode to router mode, enabling the second router to route network traffic on the network; and

replacing the first router with the configured and switched second router.

2. The method of claim 1, wherein the second router is comparatively newer than the first router.

3. The method of claim 1, wherein the first and second routers are from different manufacturers.

4. The method of claim 1, wherein invoking comprises actuating a button.

5. The method of claim 4, wherein the button is a physical button on at least the second router.

6. The method of claim 4, wherein the button is a virtual button rendered on a display.

7. The method of claim 1, wherein invoking comprises invoking the Wi-Fi Protected Setup (WPS) protocol.

8. The method of claim 1, wherein replacing comprises disconnecting the first router from the network.

9. The method of claim 1, further comprising testing the second router to determine an ability thereof to route traffic on the network.

10. A method of configuring a second router as a range-extending access point on a network comprising a first router, comprising:

placing the second router in client mode within the network such that the second router is not configured to route network traffic and is configured to search for a network access point provided by the first router;

invoking a protocol on the first and second routers, the protocol being configured to enable an exchange of at least network name and password information from the first router to the second router in client mode;

configuring the second router in client mode according to the network name and password information obtained from the first router;

leaving the second router in client mode; and

connecting the second router in client mode to the first router and moving the second router away from the first router.

11. The method of claim 10, wherein the second router is comparatively newer than the first router.

12. The method of claim 10, wherein the first and second routers are from different manufacturers.

13. The method of claim 10, wherein invoking comprises actuating a button.

14. The method of claim 13, wherein the button is a physical button on at least the second router.

15. The method of claim 13, wherein the button is a virtual button rendered on a display.

16. The method of claim 10, wherein invoking comprises invoking the Wi-Fi Protected Setup (WPS) protocol.

17. The method of claim 10, wherein connecting comprises connecting a cable between the first router and the second router in client mode.

18. The method of claim 10, further comprising testing the second router to determine an ability thereof to extend a range of the first router.

19. A router configured to route network traffic in a computer network, the router being configured to:

(1) selectively enter in a client mode in which the router is not configured to route network traffic and is configured to search for a network access point on the computer network;

(2) while in client mode, exchange at least network name and password information with another router present on the computer network according to a protocol and self-configure according to the network name and password information obtained from the other router; and

(3) selectively remain in client mode and operate as a range-extending access point to the other router or switch from client mode to router mode, to thereby enable the router to route network traffic on the network.

20. The router of claim 19, wherein the router is further configured to exchange at least the network name and the password information upon a button being actuated.

21. The router of claim 20, wherein the button is a physical button on the router.

22. The router of claim 20, wherein the button is a virtual button rendered on a display.

23. The router of claim 19, wherein the protocol comprises the Wi-Fi Protected Setup (WPS) protocol.
