Network hardware devices organized in a wireless mesh network (WMN) in which one network hardware devices includes multiple radios. A processing device of a first network hardware device receives, via a first radio, a beacon frame from a second mesh network device, scans, via a second radio, for a second mesh frame of the second mesh network device, and receives the mesh frame. The processing device determines a first sector identifier that identifies an antenna from which the mesh frame is transmitted, a first signal strength indicator value corresponding to the mesh frame, an unused radio and an unused channel of the second mesh network device. The processing device sends a first message to the unused radio of the second mesh network device on the unused channel via the second radio, receives a second message, and configures the multiple radios to communicate with the second mesh network device.
