Can the WiFi transmit power be configured?

[Ehryk]

I'm looking for options to configure the 2.4GHz and 5GHz transmit power (my 5GHz is at 17dBm and the 2.4GHz is at 29dBm). Is this completely managed by the Almond+?

I can't see any options in either the TouchUI, WebUI or OpenWRT. Perhaps I'm just missing them?

It looks like that option was removed in the current firmware. My understanding is that the options weren't working properly.
We'll be adding it back in a future firmware upgrade, but even so, both should be set to the max allowed setting by default and that might just be reported wrong.

On the A+ that I'm working with, before I upgraded to 65, the 5ghz radio was showing at max power, but (at least in the UI), the 2.4ghz radio was 1 notch below max.

EDIT: I just checked from the commandline via iwconfig. Both the 5ghz and 2.4ghz radios report at Tx-Power=29 dBm

With my A+ the 5GHz transmits at 17dBm and the 2.4GHz is transmitting at 29dBm. That is exactly opposite of what those should be. The 5GHz has a harder time passing through walls so it needs to be a higher power where the 2.4 should be much lower. At work the Aruba access points I control are usually tuned (in a higher density AP count) at around 11dBm on 2.4GHz and between 20 and 25 dBm on 5GHz.

you verified this power on the gui or at the commandline with iwconfig? There's a known bug with the GUI on power reporting, but doing 'iwconfig' as I mentioned in my previous post will tell you the true power actually being used.

This is a bug in R065 and we'll get it fixed.

One quick thing, for those of you seeing 17dBm, what 5GHz channel are you using?

I'm currently on channel 48 for the 5Ghz network, but I've bounced around a bit checking lan speeds.  Currently seeing 17 on that via iwconfig.

[LGNilsson]

The sub 100 channels will only transmit at 17dBm in North America, as this is a Wi-Fi restriction, the channels in the 100 range can transmit at higher power.

Interesting.  I did switch to channel 148 and I noticed it jump back up to 29.  Is that a restriction by the spec, or just the wireless chipset?

[LGNilsson]

That's according to the Wi-Fi regulations in North America, but varies from country to country.
Below are the US regulations and they're quite complex to say the least.
