Unless you are using external high-gain antennas, this isn't possible.
Also, txpower on most 802.11 chips tends to be out of user control. It
will make automatic changes for various reasons.

It seems, it disappeared from ifconfig because only wi supported it.
Can I be sure that my WLAN is not sending stronger than the law allows?

Looking for ifconfig '[[-]txpower dBm]' option which was present in
OpenBSD 5.4 amd64. Try to find 'txpower' on 6.0 amd64 but seems it
missed out.
Actively using it to match power for 802.11 card and it's RF recipient
(post amp). What mechanism of output power matching is

Not really supported on OpenBSD. There are stubs but most drivers don't
actually implement it. (yes this is a bit of a problem if you're using

No idea.

ifconfig(8), look for - you already named it.

Hi,
1) How can i show the txpower of my wlan-card?
2) How can i adjust the txpower?

I'm trying to do some antenna work so I want a weak signal from the
other side of the basement. So I try stuff like ifconfig athn0
txpower 1 and get "ifconfig: SIOCS80211TXPOWER: Invalid argument".
Any number I've tried gives the same thing. If I leave out the number

Hi there,
Quick question about the way ifconfig deals with txpower for ral cards..
Maybe I'm being silly, but I find it rather hard to believe that my wireless
card is transmitting at 100dBm. Yet, that's what ifconfig claims. Call me
stupid, but I'd much rather see no value
EE/RF pedant here (there had to be one, right?).
However, I doubt that e.g. subtracting 3dBm is sufficient, say
Without going into detail, it needs to be said that dB is a relative
measurement while dBm is absolute. Thus, one would state that 3 dB is
subtracted from X dBm in order to represen

Use an EU card.

FYI, I've found the following comments in the Linux Kernel source.

Hi!
With the wi(4) driver, is txpower output of ifconfig correct
for cards which are capable of more than 100mW (20dBm) power?
In the stable OpenBSD 3.9 sources the maximum is _hardcoded_ to 20dBm.
There has been only one reference (providing the code below):
http://marc.theaimsgroup.com/?l
Trying to change txpower on atheros wireless cards does not set the
power accordingly, just errors out.
I submitted this mail to bugs@ but I cannot find it in the bug
tracking system page, so I send it here also in case there was a
problem.
I don't have the skills to figure out anythi
just that. The ifconfig
man page seems to suggest that the txpower parameter (or alternatively
-txpower) is what I need, but I must be reading the syntax wrong - every
attempt so far has produced only
ifconfig: SIOCS80211TXPOWER: Invalid argument
Is txpower indeed supported (with ath cards), or
21 matches
