Dears, In Linux 2.6.22 the RSSI was measured properly for CM9 device. Afrer upgrading to 3.0.75, the RSSI measure is offseted. I even remember, that this problem has been introduced somewhere before 2.6.34. You could look at the following chart: http://78.108.103.11/cgi-bin/rodga_1month_big.cgi This is not signal drop, but a kernel change instead. (the chart is generated by parsing of iwconfig output: wlan1 IEEE 802.11abg ESSID:"dvrmn.heaven-czfree.net" Mode:Managed Frequency:5.64 GHz Access Point: 00:27:22:64:C3:02 Bit Rate=54 Mb/s Tx-Power=8 dBm Retry long limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=36/70 Signal level=-74 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:20 Invalid misc:59452 Missed beacon:0) I guess that this problem has been fixed one time and that there are two generations of CM9 devices that reports RSSI differently. best regards Jara -- 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
