I moved to within two meters of my AP with nothing blocking the way--the link quality jumped up to 46/100 (vs 3/100 5m away and a wall blocking), though there was no increase in speed (still limited to ~120 kilobits/s). Before: Link Quality=3/100 Signal level=-73 dBm Noise level=-66 dBm After: Link Quality=46/100 Signal level=-49 dBm Noise level=-69 dBm - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
