    • During, or right after, an end device's authentication attempt, the radio enters strange initial authentication state where the AccessPoint can't transmit out to the MU (end device stations). The vast majority of the time, the MU itself disassociates within 10 seconds and reassociates and the problem goes away. On rare occasions, it corrects itself in about 1 minute. There may be end devices that cannot fix themselves, and they end up stuck - due to the Access Point radio failing to transmit packets to the end device.
