A master node triggers regrouping of a plurality of repeaters in a network of a first topology by performing a number of operations. The master node transmits a discovery request to the plurality of repeaters to cause each repeater of the plurality of repeaters to conduct a scan to detect signal strengths of other repeaters of the plurality of repeaters. The master node receives information on results of the scan from each repeater of the plurality of repeaters. Based on the received information, the master node directs the plurality of repeaters to form a network of a second topology different from the first topology. ## Claims ### Claim 1 A method, comprising: triggering regrouping of a plurality of repeaters by: transmitting, by a master node, a discovery request to a plurality of repeaters in a network of a first topology to cause each repeater of the plurality of repeaters to conduct a scan to detect signal strengths of other repeaters of the plurality of repeaters;
