Hello everyone,
with the new version of the operating system(7.x L41G-2axD ) how can you maximize the wifi power?
I selected Italy as the country.

Thanks

I like to go to Australia.

On my Audience, running 7.18.2, country regulatory limit for 2.4GHz band (which is all what hAP ax lite has) for Australia is the same as for Italy (and the rest of ETSI countries) ... which is 20dBm EIRP. Alas, Brazil has limit at 30dBm ... making Copacabana my place of choice for 2.4GHz band.

Thanks for the reply,
but can the WiFi power increase be done only by changing country or is there a different place to set low, medium or high?

THANKS

Actual transmitted power depends on:

1. chipset capability (e.g. hAP ax lite can do up to 22dBm, but it gets reduced with higher interface speeds - more complex modulation schemes require tighter power control and seems that most WiFi chips are not capable of doing it at highest Tx power, hence Tx power backoff)
2. country regulatory limitations ... which are about EIRP and that one includes antenna gain (hAP ax lite has antenna gain 4.3 ... or 5 rounded up, ROS can only do integer maths)
3. manual setting of tx-power

And actual Tx power at any time is the lowest of the three limits.

It is not possible to affect the bullet #1. Default setting of bullet #3 is (IIRC) 30dBm so usually not an issue. Which leaves bullet #2 ... and "moving to" Brazil (or some other country with higher regulatory limits) helps in this case.

Do not forget that WiFi is a two-way protocol, so actual speed also depends on client device's capabilities - most of the client devices are two-chain with regulated power. Pushing the AP power may have point when you also have MT or smth else for a client.

Indeed. Device's Tx power can limit upload speeds, but I guess this is not a huge issue (until the asymmetry is not too big) because most wireless stations use data in asymmetrical manner as well (more of downlink and less of uplink). And lack of device's Tx power most often means that at same range (where downlink still works satisfactory) uplink speeds drop due to fall-back to more robust modulation schemes at which Tx power backoff is less (and Rx sensitivity is better).
But device's Rx sensitivity does affect downlink speeds and some devices are more "deaf" than others.

Because there is a LTE modem on board can achieve 25dBm with Australia or Superchannel selected?

Presence of LTE modem has nothing to do with WiFi Tx power.

But I'll be damned: I went to check reg-info for Australia on different wifi devices, all running ROS 7.18.2. As I already mentioned, on Audience regulatory limit is set at 20dBm. But when checking on wAP ax I was mighty surprised, there reg-info says the limit is at 36dBm. On RB951G (running legacy wireless driver) limit is 36dBm as well. On hAP ac2 (without any wifi driver, it's used as main router and CAPsMAN) the limit is 20dBm.

I also checked a few older devices, which are running ROS 6.49.18: hAP has limit at 36dBm, hAP ac lite as well.

So I've no idea about why a few devices have much lower country limit for Tx power for Australia. I'd say it's because of wifi-qcom-ac driver but my hAP ac2 doesn't run any wifi driver.
