Dear List, I'm trying two equipment in outdoor use, one (master mode) 586 with UBIQUITI SR5 mini-pci and in the other side (managed mode) same one like the first, in both sides I have Linux 2.6.11 with madWiFi driver. As you can see, the signal level is between the range of operation, the retry is in excess and the throughput is so poor. Somebody can help me please? *Real throughput: 700 Kbps with peek of 1100Kbps * *Master side (without traffic):* ath0 IEEE 802.11a ESSID:"XXXXX11a" Mode:Master Frequency:5.8 GHz Access Point: 00:01:B4:xx:xx:xx Bit Rate:0 kb/s Tx-Power:50 dBm Sensitivity=0/3 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=33/94 Signal level=-62 dBm Noise level=-95 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:61198 Invalid misc:61198 Missed beacon:0 *Managed side** (without traffic)**:* ath0 IEEE 802.11a ESSID:"XXXXX11a" Mode:Managed Frequency:5.8 GHz Access Point: 00:01:B4:xx:xx:xx Bit Rate:36 Mb/s Tx-Power:50 dBm Sensitivity=0/3 Retry:off RTS thr:off Fragment thr:off Encryption key:off Power Management:off Link Quality=31/94 Signal level=-64 dBm Noise level=-95 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:126339 Invalid misc:126339 Missed beacon:42 *athstatus** (without traffic)**:* input output altrate short long xretry crcerr crypt phyerr rssi rate 32396 128466 17 0 1263717 126339 7 0 0 31 36M 0 0 0 0 0 0 0 0 0 31 36M 0 0 0 0 0 0 0 0 0 31 36M 0 0 0 0 0 0 0 0 0 31 36M 0 0 0 0 0 0 0 0 0 31 36M 0 0 0 0 0 0 0 0 0 31 36M * athstatus making traffic with ttcp (tcp traffic injector) from managed to master:* input output altrate short long xretry crcerr crypt phyerr rssi rate 32657 129251 33 0 1271067 127062 26 0 0 31 36M 0 0 0 0 0 0 0 0 0 31 36M 0 0 0 0 0 0 0 0 0 31 36M 28 79 0 0 541 54 3 0 0 25 24M 27 75 0 0 732 73 2 0 0 21 12M 17 54 0 0 590 59 4 0 0 21 6M 11 50 0 0 420 42 1 0 0 22 6M 17 48 0 0 482 48 0 0 0 23 6M 14 48 0 0 430 43 0 0 0 19 6M 10 48 0 0 440 44 0 0 0 23 6M 12 46 0 0 460 46 0 0 0 22 6M 11 47 0 0 470 47 0 0 0 22 6M Regards, Claudio |
