1. A computer-implemented method in a Wi-Fi controller communicatively coupled to a data communication network to manage a plurality of access points, for capturing multiuser data packets by grouping access points on a wireless network, the method comprising:
forming a capture group of access points selected from the plurality of access points dedicating at least one radio from each of the access points for capturing data packets;
receiving captured data packets from the capture group of access points, wherein the captured data packets were each captured at, and forwarded from, one of the plurality of access points having multiple transceivers, and wherein at least one of the multiple transceivers is in packet capture mode;
analyzing the captured data packets to identify a set of multiuser data packets based on parallel transmission time and common data from each data packet; and
checking the set of multiuser data packets against a set of rules for multiuser data packets to troubleshoot wireless network issues.
