Radio Power settings

[-=thrasher=-]

So, both firmwares are limited, right? And there is no difference in the signal strength?


Actually, according to sources, you need just this to achieve the same:

nvram set regulation_domain=0x00
nvram commit
reboot

Ah I suspected the other settings were either informational only, or derivatives of the regulatory domain.

Correct in that by methods I have described, no further output is measurable.
However...

I discovered a parameter which seems to control the power amp's output via some sort of feedback loop. I haven't discovered the exact nature of each parameter (they're kind of cryptic) but here it is:

wl atten 0 0 80

I have attached a stumbler (i know, kinda rough) but it shows the dramatic difference this parameter makes. I have an unrefined script I have used to try and automate the whole thing to some degree (just ignore the rate stuff). It's very unfinished and I wish I knew more to refine it but time may permit..

It's only taken me 16 hours straight to get this far, how hard can it be?

(Please be responsible with this set of commands, they're not the sort of thing that would suit use in a city or hi-density residential. Get a better antenna first.) I hope this doesn't trigger broadcom to lock their drivers down even further - do you think this may happen? I hate to say it but if so it may be prudent to censor the info from the public web. Let me know what you think.

cheers

wl mrate 2
wl bg_rate 2

EDIT:
The txpwr1 command has absolutely no effect afaik. no dbm change in output.
Also the rubbish about burning out cards with higher output power is nonsense. I just had the lid off the RF section and felt the BCM2050 chip. Warm, nothing unusual after 30 mins of max pwr operation at full 54mbps transmit duty cycle.
