Comment:
HI,
I have two SR5 in two endpoints. One configured as Master (AP), and the
other as STA.
The STA system uses an old driver without patch:
ath_hal: 0.9.16.13 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413,
RF5413, DFS)

wifi0: Atheros 5212: mem=0xa0000000, irq=10
the AP system uses more new (patched):

The Distance Between Antenna Sites is 7 Km (4.35 miles). I use a 30 dbI
antennas.
In http://tranzeo.com/cgi-bin/wireless.cgi I see that the RX power maybe
-50dBm, with -21dBm tx.
STA do not have a patch txpower (ticket/508)
AP system have a 1518 svn (with patch included in SVN, right?)
I don't set tx power in STA (old) system, that uses default;
I set tx power in 18 (or 17, or 16) dBm in AP system.
The power receive in STA is 10dB lower than the power receive in AP. So,
the STA tx power is +10 dB than AP.
STA:
ath0 IEEE 802.11a
Mode:Managed Frequency:5.805 GHz
Bit Rate:24 Mb/s Tx-Power=18 dBm Sensitivity=0/3
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=31/94 Signal level=-64 dBm Noise level=-95 dBm
AP:
ath0 IEEE 802.11a
Mode:Master Frequency:5.805 GHz
Bit Rate:0 kb/s Tx-Power=17 dBm Sensitivity=0/3
Retry:off RTS thr:off Fragment thr:off
Power Management:off
Link Quality=42/94 Signal level=-53 dBm Noise level=-95 dBm
Well... The information in http://madwifi.org/wiki/UserDocs/Ubiquiti:
"firmware add 10dB in txpower set with iwconfig" is not true, with patch
Can I help with more tests?
