If you're comparing product briefs or datasheets, make sure you're comparing numbers for the same bitrate. That card can receive 1Mbps down to -90dBm, and 6Mbps down to -88dBm. You'll find cards with sensitivity 6 or 7dB better, but that's about it. -Brian -- 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
