Abstract
Network hardware devices organized in a wireless mesh network (WMN). A first mesh network device includes processing logic that detects an error condition of a first wireless link to a next hop node in a wireless path between a second mesh network device and a third mesh network device. The processing logic sends, via a first radio of the first mesh network device, a first frame with a first path error message over a second wireless link to a precursor hop node in the wireless path. The first path error message identifies the error condition of the first wireless link. The processing logic generates a second frame with a copy of the first path error message and sends, via a secondary radio of the first mesh network device, the second frame with the copy of the first path error message.
