Abstract
Connection issue prediction may be provided. A computing device may receive first Channel State Information (CSI) for a first link associated with a client device. The first CSI may be collected when beamforming was trained on a second link associated with the client device. Second CSI may be received for the first link associated with the client device. The second CSI may be collected at a time subsequent to when beamforming was trained on the second link associated with the client device. A correlation between the first CSI and the second CSI may be determined to be below a predetermined threshold. A status of the beamforming performed on the second link associated with the client device may be set to stale in response to determining that the correlation between the first CSI and the second CSI is below the predetermined threshold.
