Comment:
Yes, this problem still exists. But I don't think it can be fixed.
Wireless output power has been 'unreliable' every since I got 6 of the
units, occassionally on the 2.4GHz band, but the 5GHz band is the
weirdest. I've seen all kind of results from a lot of experimenting. On
current trunk, channel 40 will use 20dBm, channel 44, 15dBm and channel 36
at 17dBm. Regulatory settings, jows reghack and ATH_USER_REGD seems to
have some influences on results. But in the end it's all about play the
"settings game" till a somewhat desired result is achieved. Kernels and
patches seems to have little effect, other than adding some "confusion" to
how to get to the desired configuration result
(channel/width/dBm/maxrate).
So I think it's harware/eeprom/ART related. And even if it could be
overridden by clever hacking that would probably just mean
regulatory/legal issues.
What do you think of this, developers?
