This type of error is usually because of RF interference. When the AP sends a packet to the client, the client must ACK this packet back to the AP, if the AP receives no ACK from the client, it will resend this packet. It will continue this process for 16 times (default config) before assuming the client is off the network now (person moved out of range or powered off their computer) and will remove the client from its association table. I would verify coverage via a site survey, looking at not only signal strength, but also signal quality
