I forgot to add the speeds before and after the 12 -> 26mW change:
Result (Xperia 1V):
Result (S7 Tab):
@825i Increasing Tx Power leads to more noise, it may/may not increase performance. It's basically aim is to increase the range of your router. However, this could also increase heat and load.
If I'm not mistaken, the txpwr_target_max key only indicates the maximum allowed Tx Power, it doesn't increase the value. It's a dynamic value based on the selected country, etc.
Thanks for posting your findings and results. Like said in the disclaimer, it may work for you or not.
In most cases unfortunately it doesn't work, because many WiFi-chipsets have hidden/unknown abilities to check if the receiving/sending values are valid. So even changing the country or Tx Power, it may not change anything to your end-devices.
AX1100 Merlin 388.7 - so far no luck with unlock TX,
wl txpwr_target_max Maximum Tx Power Target (chanspec:0x1003): 12.00 12.00 12.00 12.00
Power really sucks, even cheap router totolink has 100% more efficient at my home.
One wall and AX don't have 2.4Ghz,,,
I tried downgrade to 388.1 and same issue can't change territory and tx.
nvram show | grep -e 'country_code|location_code|territory_code|ccode'
0:ccode=#a
1:ccode=E0
2:ccode=E0
3:ccode=E0
location_code=#a
territory_code=EU/01
wl0_country_code=E0
wl1_country_code=#a
wl2_country_code=E0
wl_country_code=#a
I have Asus GT AXE16000 with Merlin 388.7 Are you able to change region successfully if yes then which method worked for you ?
Finally i found solution, FW is not problem. But seems change parameters by wl -i eth6 and rest (7) (8) doing job, higher tx power can be achieved. And lucky have much more efficient wirelesses network with good range.
When i fully and permanent solve it will post here.

Followed steps on a GT-AX6000 from Germany. Tx power did increase and better signal (signal strength from same spot -58dbm to -44dbm). New channels (149 and up) appeared as well. GUI changes seems to not cause issues and I can swap to other channels in GUI. However, whenever I try to connect to channel 149 from an Intel AX211 card, Windows shows I am using wifi 4 instead of wifi 6. Lower channels (36, 44, 48 etc) are fine. Is this an Intel issue like the previous posts indicated? Thanks for the help and good luck everyone.
@pewpewpew47 Could you try forcing 802.11ax in the WiFi settings? You may also need to adjust some parameters.
It could indeed also be the Intel card not accepting the connection as it should.
@QaDoPL Thanks for sharing, I think I'll add the WiFi settings to the README.

Most likely yes. And or a combination with the OS. You can try with another client and see if it works as expected.
You can check on our router how your client is connected, this gives you all the details.
Here for eth7 on my router:
wl -i eth7 assoclist
=> MAC_ADR
wl -i eth7 sta_info MAC_ADR
If you want to dig deeper: Capture 802.11 beacon frames with wireshark. Then you will see what your router is advertising, and how the handshake with the client goes on....
I have updated the instructions to use events, meaning it should work when changing Wireless settings in the GUI.
Could you please test? I have also added to multiple places, as it seems to be the only way to make sure settings are set on boot and such.
however it would be more practical to have an archive containing all the scripts that work for a specific model with their respective instructions for use. not all scripts work for everything in most cases if for example you used a script for an AX6000 on an AC86u the gui becomes in Chinese language and that's it

Thanks Pasko! After some digging with your command line, I found that 149-169 does not work when 160mHz bandwidth is selected. Currently I just run my router on auto channel and auto bandwidth (been on channel 100/160 since last reboot). I live close to airport so DFS may also have something to do with the issue.

Redid all the nvram changes after your update. Can confirm GUI changes persist after restart on GT-AX6000. Thanks mate!
@pewpewpew47 Thanks for testing! Yeah, it seems to be persistent now. :)
Hi Does anyone know how to disable DFS using nvram without changing country/local/transmit power? I can do it using wl command but it's not persistent.
@omrij, can you share the wl command you're using to disable DFS? Thanks!

Something like this (adjust channel and other things you need)
wl -i eth7 down
wl -i eth7 regulatory 1
wl -i eth7 spect 0
wl -i eth7 chanspec 100/160
wl -i eth7 up
Great, tried and working, thanks again!
confirmed working on ax86u pro
enabling the missing channels doesn't seem to work on my ac68u, did on my ac88u both on merlin 386.14,
the country codes reset on reboot,
settings for 5G
wl -i eth7 down wl -i eth7 regulatory 1 wl -i eth7 spect 0 wl -i eth7 chanspec 100/160 wl -i eth7 up
Thanks @omrij ! Had to change eth7 to eth6 for the AX82U. DFS is borked on this model so I'm glad my WiFi will now stay up.
@Squall-Leonhart Please dump the unmodified first nvram dump, and compare the values with the provided one. You may need to have different values, my model isn't that new, so I cannot test unfortunately.
found the reason, unlike ac88u which can retain these values over reboot, the ac68u forcibly copies the cfe values back to nvram, so you have to add them to init-start.
@Squall-Leonhart Yes, see updated instructions, because you basically have to add them all of the place lol.
Hy,
Is there a solution to change country code in asus tuf-ax5400?
Thanks
Hy, Is there a solution to change country code in asus tuf-ax5400? Thanks
Unfortunately not. Only works with Merlin firmware, for which there are no releases for non-broadcom routers.

You can install GNUton's firmware which is an official fork of Merlin and supports TUF-AX5400 https://github.com/gnuton/asuswrt-merlin.ng
Well spotted @argh0815
does it have to be for Merlin routers?
I have RT-AX58U V2 without merlin!!

Ok adding on to what I have learned from fooling around a bit.
My AX88U shipped with "DE" country. This limited transmission power to 12, i.e.:
After copying the example script and rebooting the router:
So the Tx power has increased by a bit over double. I can also see from numerous WiFi apps and also the Asus Site Survey/WiFi Radar that my transmission power has increased massively. Note that I have not copied any of the "Risky" transmission lines into my start script. All I have in my start script is what I have in the reply above.
2.4Ghz
5Ghz
I am pretty satisfied with this. It would have been nice to use Channel 14, but I can concur and confirm with others. Setting the channel to 14 will generally reset my router to "DE" region again and put the Tx power back to 12 from 26. This is generally good enough for me.
Hopefully there's no health risks from setting the Tx power so high. I sit about 1.2m from my router. Though I plan to move it into another room when I move my study area. Hence part of the reason why I started investigating this in the first place.
