Abstract:
A device and method enable reestablishing a wireless connection in a wireless network. A first wireless device detects that a previous wireless connection has been lost with a second wireless device that employs dynamic frequency selection (DFS). The first wireless device then uses a routing table to identify a third wireless device as a next hop of a route to the second wireless device, and transmits a request message to the third wireless device, where the request message requests identification of a current DFS channel over which the second wireless device is operating. Next, the first wireless device receives a response message from the third wireless device, where the response message identifies the current DFS channel over which the second wireless device is operating. Using the current DFS channel, the first wireless device establishes a new wireless connection with the second wireless device.
