But doesn't it also mean that this change increases probability that the client doesn't receive the probe response, for example due to interference where retransmission would help, and hence the AP isn't included in the client's scan results? -- Kalle Valo -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
