1. A method comprising:
causing an Access Point (AP) to decline new association requests received from client devices not associated with the AP;
causing the AP to instruct client devices associated with the AP that detect a signal level from the AP to be below their roaming margin to roam away from the AP;
decreasing, after causing the AP to instruct client devices associated with the AP that detect the signal level from the AP to be below their roaming margin to roam away from the AP, power of the signal level from the AP by a predetermined amount;
repeating causing, after decreasing the power of the signal level from the AP by the predetermined amount, the AP to instruct client devices associated with the AP that detect the signal level from the AP to be below their roaming margin to roam away from the AP and decreasing, after causing the AP to instruct client devices associated with the AP that detect the signal level from the AP to be below their roaming margin to roam away from the AP, the power of the signal level from the AP until the power of the signal level from the AP is at a predetermined level;
increasing, when one or more active client devices remain associated with the AP when the power of the signal level from the AP is at the predetermined level, an acceptance interval for packets from the client devices that remain associated with the AP when the power of the signal level from the AP is at the predetermined level; and
rebooting, after repeating and increasing the acceptance interval, and when active client devices are moved from the AP, the AP.
