I have laptop with ath5k card, and just tried to run it with ath5k driver.
I notice strange thing:
lappi ~ # iw phy phy0 info
Wiphy phy0
Band 1:
Frequencies:
* 2412 MHz [1] (20.0 dBm)
* 2417 MHz [2] (20.0 dBm)
* 2422 MHz [3] (20.0 dBm)
I guess it is too high. I am not sure it is actual value, but if it is right
and actual value, then i am exceeding local regulations.
I have simple spectrum analyzer (spectran), and i can try to test actual
output power if required.
Another thing, is it possible to change antenna output?

The code's already there in the driver, there's just not any interface
to do it from cfg80211 yet. If you want to hack the driver just look
for the antenna-related defines :)

Sorry for my ugly English.
In madwifi, as i remember i was possible to do that or over sysctl or over
module parameter, i dont remember exactly where.

You are right. I search in registry and .inf files, there is nothing vendor
specific. Most probably what is exist now - enough for laptops.

That value is the maximum value allowed, not your actual eirp. By
default the EEPROM's card is read and that is used for regulatory
purposes, users can however be good citizens and help regulatory
compliance further by indicating their country and if the max eirp of
the programmed EEPROM is higher than your current country it will be
lowered.
Please have a good read at:

You obviously can change the antenna on a lot of devices, sometimes
that is difficult due to the connectors used but you are likely to
find them online somewhere.

You mean can you do antenna diversity and select this manually ? I am
not sure, but I doubt it, should be easy to add though.

I know, but as i know there no way to know to which connector vendor plugged
antenna cable.

ath5k and madwifi are very different.

How do we do this for windows then?

Yes, on some laptops wireless card connected really weird way. And while on
Windows everything worked fine, on Linux signal was too weak, and some people
thinking it is driver issue.
I had this issue with madwifi before, and choosing antenna manually helped.
But it was long time ago, no idea if it's useful now in ath5k. But in custom
boards like Routerboard it is very useful.
