#10897 new defect

incorrect txpower output

Reported by: Halo2 Owned by: developers
Priority: response-needed Milestone: Barrier Breaker 14.07
Component: base system Version: Trunk
Keywords: Cc:

Description

Same on WZR-HP-AG300H (AR9280) as on Ubiquiti UB5 (AR5414) (ar71xx plattforms, onboard vs. a very different PCI card - but same behaviour, both "hp" devices)

6dB lower output power than set in /etc/config/wireless and shown with iwlist txpower.
See attached screenshots as evidence.
Tested multicast and unicast, and compared with a reference device

config 'wifi-device' 'radio?'
        option 'type' 'mac80211'
        option 'macaddr' '??:??:??:??:??:??'
        option 'hwmode' '11ng' / '11na' (see screenshot)
        option 'htmode' 'HT20'
        list 'ht_capab' 'SHORT-GI-40'
        list 'ht_capab' 'TX-STBC'
        list 'ht_capab' 'RX-STBC1'
        list 'ht_capab' 'DSSS_CCK-40'
        option 'disabled' '0'
        option 'diversity' '0'
        option 'txantenna' '1'
        option 'rxantenna' '1'
        option 'noscan' '1'
        option 'channel' '1' / '36' / '120' (see screenshot)
        option 'distance' '12000'
        option 'country' 'AT'
        option 'txpower' '12' / '14' / '10' / '22' (see file name)

But a Bullet M5 for example was exactly in a 10% range as it should be (but with diversity 1 and tx/rxantenna 0, unfortunately i cannot crosstest this at the moment).

Retested with r31261.

Good now on WZR-HP-AG300H!

But others:
~okay on R52n.
~1.5db too less on SR71.
~6db too less on WLM200NX.
~3db too much on Bullet M2.
