@Warborn123 Unfortunately this is in most cases hardware related. They seem to force the region, with some hidden signals. Yeah, it's pretty weird.

So even when you set it, it doesn't mean it (fully) works.

@Warborn123 : Were you also able to change 6 GHz channels on your AXE11000, i.e., to allow those US/Canada channels (channel 97, 6435 MHz and above) that are "forbidden" here in Europe?

Yep, it's quite wild. I guess it has something to do with that ccode=ALL or wl2_country_code=ALL. My router now has almost all the frequency band unlocked for 2.4, 5 and 6GHz.

But I think location_code was the one that actually affected txpwr_target_max and had it increased from 15.25 to 25 dBm, and this also seems to be persistent. wl*_country_code are just set by the value of location_code.

Ubiquiti WiFiman also states 25 dBm, and I get the impression that my connection in the, from the router, most remote room has improved.

@sarusani : Cool, let's see how much you are really blowing out 😁

  1. First check the maximal allowed dbm per channel, for 5GHz most likely eth6 is the correct interface on your router model: wl -i eth6 chanspec_txpwr_max
  2. Then check the nominal power (on some Asus models this is simply the value from 1. minus 1.5 dB): wl -i eth6 txpwr_target_max
  3. Check the maximum power with wl -i eth5 txpwr1 (Note: You can set this up to 30.75 dbm or so, but you cannot get this much of power out, because it is capped by the limit from 1.)
  4. With this you can check the last actual used power per antenna: wl -i eth6 txpwr_adj_est

Let's see how well your router is hearing your clients

  1. First see who is connected, for 5 GHz most likely the interface is eth6: wl -i eth6 assoclist
  2. Then for each connected client you can check: wl -i eth6 sta_info MAC ADDRESS OF CLIENT, then you see amomg many things, RSSI

In general, if your client has a very low RSSI seen from the AP, then you should try to improve Tx power on the client side. If your client runs on linux and has a wifi card which is not self-managed, then there might be options to do that, e.g., changing regulatory country settings with iw reg set XX etc. However: If your client has an Intel card, e.g., AX-2XX, with LAR (Location-Aware Regulatory), then you have to stick what LAR detects as country, you cannot override it with iw because the interface is shown as self-managed by LAR 💩

I tried to get some infos, but I'm not very successful...

If I look at the nvram show data I can find eth0 & eth1 eth2:

acs_ifnames=eth1 eth2
wl_ifnames=eth1 eth2
lan_ifnames=vlan1 eth1 eth2
wl_ifname=eth2
wl0_ifname=eth1
wl1_ifname=eth2
wan_ifnames=eth0
wan0_ifname=eth0
ipv6_ifname=eth0

So eth1 is 2.4GHz and eth2 is 5GHz.

Was just an enquiry but i hope your reply helps someone else understand too. I don't really have any connection problems, my furthest device gives an RSSI of -64dBm on 5GHz. I've also managed to tune to output power down a little to reduce interference with my wireless headphones.

is there any way to set the territory code on an ac86u? i have also tried creating a chrono job, but nothing, once the router reboots it returns WE/02 and the AC script is not activated. also i would like to understand which country this code belongs to because it does not appear anywhere

@Reeplosin and all fyi

In general: If you restart wireless service, you will always return to the values (country etc.) fixed in the driver/firmware (or more precise: To the specific selection burned in the ROM out of all possible values in the driver, see below) So, restarting of wireless service happens also--apart from view exceptions as mentioned above in the comments--when you change settings via GUI.

Thus, there are two ways to overcome this a) put NVRAM changes in the init-start script (and then never issue a restart of wirelss service) or b) do the changes via wl command.

For a) See comments above and follow the golden rule not to restart wireless service!

For b) :

  • make sure you have latest wl version, i.e. flash latest merlin firmware. On my AX58U and AXE11000, both on 3004.388.6_2, wl ver Broadcom BCA: 17.10 RC157.2809 wl0: Dec 15 2023 10:37:38 version 17.10.157.2809 (r801046) 8e0370b

  • check available commands of wl with: wl -h and, yes this gives a different result, wl -i eth6 -h (assuming eth6 is 5G here, you need to check devices on your router model)

  • Check which countries are available in your current firmware: wl country list You can only select one of this country listed here.

  • Each country comes with a certain list of "revisions". These are regulatory settings that have changed over time, you can check which ones are supported with e.g., wl country_rev US

  • You set a country with a specific revision as wl -i ethXX country "US/699" (For Country = ALL you don't need to specify the revision)

  • So, you can do on your asus, assuming eth6 is 5G:

wl -i eth6 down
wl -i eth6 country ALL
wl -i eth6 country_abbrev_override "US"
wl -i eth6 regulatory 1
wl -i eth6 chanspec 36/160
wl -i eth6 up
wl -i eth6 5g_rate auto
wl -i eth6 txpwr1 -o -m 1496

Result:

  1. Country ALL will result in the maximum power your device can blow out in 2G / 5G / 6G and make all channels selectable. The maximum power your router can blow out is limited in the driver/firmware for country = ALL. You cannot go higher than this, independant what you select in NVRAM or with 5. below. These values are fixed in the CLM (country locale matrix) Blob loaded into the driver. Check it wich wl clmver. Or if you manage to hack the CLM Blob, you could override and load it via wl -i eth6 clmload

  2. country_abbrev_override "US" this will make your wifi now look as if it has country US although it is set to ALL, i.e. the 802.11 beacon contains now country = US. This is very useful, if your clients in STAtion mode detect country settings based on beacon country info. If you don't send country info in the beacons, i.e. just set country to ALL, then your wifi client might switch to "world" mode. This is the least common denominator of all regulations on this planet, i.e. the most conservative setting: No (!) 6G and in 5G only very few channels with very little Tx power...

  3. regulatory 1 : Set 5G to 802.11d and disable 802.11h (DSF). You can check it with wl -i eth6 spect 802.11d mode

  4. chanspec : Set your channel here NOT in the GUI! Remember: Setting it in the GUI, will return to ROM settiings. For 80 or 160 MHz channels, you need to select a 20 MHz channel in the 80/160 MHz and not the center frequency of the 80/160 MHz channel. This will not work.
    Even on a AX58U you can use the full UNII-4 band, i.e. 165/160 is possible. Don't know if this will work on your router.
    Check settings with wl -i eth6 status Mode: Managed RSSI: 0 dBm SNR: 0 dB noise: -87 dBm Channel: 165/160 ...

  5. txpwr1 : See my comment above what this means.

NOTE: If your client uses Intel AX-2xx adpaters: You will always end up in a mess!! They use LAR... I changed to Mediatek MT7922 (RZ616). This one even gives me 6G on Windows 10 and has no LAR, so you can use all wifi channels.

@pasko-zh Very good info, will try to add it to the README. 👍

You could workaround LAR, but I don't think it's possible anymore, since most devices/firmwares use hidden signals as well. So even when you could disable LAR somehow, it would potentially be something else checking your country code.

Could you give more information about the county+ other nvram settings? I'd always understood CN/02 was the best one.

@Reeplosine tutto per tua informazione

In generale: Se si riavvia il servizio wireless, si ritorneranno sempre ai valori (paese, ecc.) fissati nel driver/firmware (o più precisamente: alla selezione specifica masterizzata nella ROM tra tutti i valori possibili nel driver, vedere di seguito) Pertanto, il riavvio del servizio wireless avviene anche, a parte le eccezioni di visualizzazione come menzionato sopra nei commenti, quando si modificano le impostazioni tramite la GUI.

Pertanto, ci sono due modi per superare questo problema: a) inserire le modifiche NVRAM nello init-startscript (e quindi non riavviare mai il servizio wirelss) oppure b) eseguire le modifiche tramite wlcomando.

Per a) Vedi i commenti sopra e segui la regola d'oro per non riavviare il servizio wireless!

Per b):

  • assicurati di avere la versione wl più recente, ad esempio installa l'ultimo firmware Merlin. Sul mio AX58U e AXE11000, entrambi su 3004.388.6_2,wl ver Broadcom BCA: 17.10 RC157.2809 wl0: Dec 15 2023 10:37:38 version 17.10.157.2809 (r801046) 8e0370b
  • controlla i comandi disponibili di wl con: wl -he, sì, questo dà un risultato diverso wl -i eth6 -h(supponendo che eth6qui sia 5G, devi controllare i dispositivi sul tuo modello di router)
  • Controlla quali paesi sono disponibili nel tuo firmware attuale: wl country listpuoi selezionare solo uno dei paesi elencati qui.
  • Ogni paese viene fornito con un determinato elenco di "revisioni". Si tratta di impostazioni normative che sono cambiate nel tempo, puoi verificare quali sono supportate con ad es.wl country_rev US
  • Imposta un paese con una revisione specifica come wl -i ethXX country "US/699"(Per Paese = TUTTI non è necessario specificare la revisione)
  • Quindi, puoi fare sul tuo Asus, supponendo eth6 che sia 5G:
wl -i eth6 down
wl -i eth6 country ALL
wl -i eth6 country_abbrev_override "US"
wl -i eth6 regulatory 1
wl -i eth6 chanspec 36/160
wl -i eth6 up
wl -i eth6 5g_rate auto
wl -i eth6 txpwr1 -o -m 1496

Risultato:

  1. Country ALL garantirà la massima potenza che il tuo dispositivo può erogare in 2G / 5G / 6G e renderà tutti i canali selezionabili. La potenza massima che il router può erogare è limitata nel driver/firmware per paese = TUTTI. Non puoi andare più in alto di questo, indipendentemente da ciò che selezioni nella NVRAM o con 5. di seguito. Questi valori sono fissi nel BLOB CLM (matrice locale paese) caricato nel driver. Controlla quale wl clmver. Oppure, se riesci ad hackerare il BLOB CLM, puoi sovrascriverlo e caricarlo tramite wl -i eth6 clmload
  2. country_abbrev_override "US"questo farà sembrare che il tuo Wi-Fi abbia il paese USA anche se è impostato su TUTTI, ovvero il beacon 802.11 contiene ora paese = USA. Ciò è molto utile se i tuoi client in modalità STAtion rilevano le impostazioni del paese in base alle informazioni del paese del beacon. Se non invii informazioni sul paese nei beacon, ovvero imposti semplicemente il paese su TUTTI, il tuo client Wi-Fi potrebbe passare alla modalità "mondo". Questo è il minimo comune denominatore di tutte le normative del pianeta, ovvero l'impostazione più conservativa: niente (!) 6G e in 5G solo pochissimi canali con pochissima potenza Tx...
  3. regulatory 1: imposta 5G su 802.11d e disabilita 802.11h (DSF). Puoi verificarlo conwl -i eth6 spect 802.11d mode
  4. chanspec: Imposta il tuo canale qui NON nella GUI! Ricorda: impostandolo nella GUI, verranno ripristinate le impostazioni della ROM. Per i canali da 80 o 160 MHz, è necessario selezionare un canale da 20 MHz nel canale 80/160 MHz e non la frequenza centrale del canale 80/160 MHz. Questo non funzionerà.
    Anche su un AX58U è possibile utilizzare l'intera banda UNII-4, ovvero è possibile 165/160. Non so se funzionerà sul tuo router.
    Controlla le impostazioni con wl -i eth6 status Mode: Managed RSSI: 0 dBm SNR: 0 dB noise: -87 dBm Channel: 165/160 ...
  5. txpwr1 : Vedi il mio commento sopra cosa significa.

NOTA : Se il tuo client utilizza adattatori Intel AX-2xx: finirai sempre nei guai!! Usano LAR... Sono passato a Mediatek MT7922 (RZ616). Questo mi dà anche il 6G su Windows 10 e non ha LAR, quindi puoi usare tutti i canali Wi-Fi.

Interesting indeed. if i understand correctly i have to enter those commands inside the router, and do nvram commit right? seeing the model not if it also applies to ac86u, but i will take a look

Well, the wl command is a difficult animal. The help file is not really correct, i.e., many commands don't work. Some work on some models and some not. If you update the readme, this has to be clearly stated.
For instance, country_abbrev_override "US works on some router models, on some not. Also txpwr1 -o, where o stands for override, does not work...

Country Code:

  • The most less restrictive country setting, wrt to channels and Tx power, is #a (#a/0) <unknown>. (Whether set via NVRAM or via WL tool does not matter). You can easily compare different country settings regarding Tx power with wl -i ethXXX chanspec_txpwr_max. See above how to set a country per interface via WL tool.
  • Also, you cannot set your router to a country which is not in your firmware. Even if you set it in NVRAM, it has no effect. You get all supported countries via country list, see example for me (E0 is a superset for some european countries)
wl -i eth8 country list
Supported countries: country code and long name
#a
CA      CANADA
E0
KR      KOREA, REPUBLIC OF
US      UNITED STATES

So, no China 😀
Trying to set to China, gives:

wl -i eth8 country "CN"
wl: Unsupported

Concerning country setting, you have to experiment, what your wifi clients accept and what is more confusing them. For instance, setting country_abbrev_override = OFF and thus transmitting no country info in the 802.11 beacons, seems to work better with Ubuntu, even for 6G, but then my Pixel 7a does not "see" my 6G AP anymore... a bit of a kindergarten...

  • Ogni paese viene fornito con un determinato elenco di "revisioni". Si tratta di impostazioni normative che sono cambiate nel tempo, puoi verificare quali sono supportate con ad es.wl country_rev US
  • Imposta un paese con una revisione specifica come wl -i ethXX country "US/699"(Per Paese = TUTTI non è necessario specificare la revisione)
  • Quindi, puoi fare sul tuo Asus, supponendo eth6 che sia 5G:
wl -i eth6 down
wl -i eth6 country ALL
wl -i eth6 country_abbrev_override "US"
wl -i eth6 regulatory 1
wl -i eth6 chanspec 36/160
wl -i eth6 up
wl -i eth6 5g_rate auto
wl -i eth6 txpwr1 -o -m 1496

Risultato:

  1. Country ALL garantirà la massima potenza che il tuo dispositivo può erogare in 2G / 5G / 6G e renderà tutti i canali selezionabili. La potenza massima che il router può erogare è limitata nel driver/firmware per paese = TUTTI. Non puoi andare più in alto di questo, indipendentemente da ciò che selezioni nella NVRAM o con 5. di seguito. Questi valori sono fissi nel BLOB CLM (matrice locale paese) caricato nel driver. Controlla quale wl clmver. Oppure, se riesci ad hackerare il BLOB CLM, puoi sovrascriverlo e caricarlo tramite wl -i eth6 clmload
  2. country_abbrev_override "US"questo farà sembrare che il tuo Wi-Fi abbia il paese USA anche se è impostato su TUTTI, ovvero il beacon 802.11 contiene ora paese = USA. Ciò è molto utile se i tuoi client in modalità STAtion rilevano le impostazioni del paese in base alle informazioni del paese del beacon. Se non invii informazioni sul paese nei beacon, ovvero imposti semplicemente il paese su TUTTI, il tuo client Wi-Fi potrebbe passare alla modalità "mondo". Questo è il minimo comune denominatore di tutte le normative del pianeta, ovvero l'impostazione più conservativa: niente (!) 6G e in 5G solo pochissimi canali con pochissima potenza Tx...
  3. regulatory 1: imposta 5G su 802.11d e disabilita 802.11h (DSF). Puoi verificarlo conwl -i eth6 spect 802.11d mode
  4. chanspec: Imposta il tuo canale qui NON nella GUI! Ricorda: impostandolo nella GUI, verranno ripristinate le impostazioni della ROM. Per i canali da 80 o 160 MHz, è necessario selezionare un canale da 20 MHz nel canale 80/160 MHz e non la frequenza centrale del canale 80/160 MHz. Questo non funzionerà.
    Anche su un AX58U è possibile utilizzare l'intera banda UNII-4, ovvero è possibile 165/160. Non so se funzionerà sul tuo router.
    Controlla le impostazioni con wl -i eth6 status Mode: Managed RSSI: 0 dBm SNR: 0 dB noise: -87 dBm Channel: 165/160 ...
  5. txpwr1 : Vedi il mio commento sopra cosa significa.

NOTA : Se il tuo client utilizza adattatori Intel AX-2xx: finirai sempre nei guai!! Usano LAR... Sono passato a Mediatek MT7922 (RZ616). Questo mi dà anche il 6G su Windows 10 e non ha LAR, quindi puoi usare tutti i canali Wi-Fi.

I performed the operation, I understood that the router after entering the commands should never be restarted otherwise everything returns as before, if I created a script to avoid having to do it manually would it work?

@Reeplosin : You can run it manually or install it in a startup script. But you might call your script services-start instead of init-start, because you can use wl tool commands only after all services are up, see https://github.com/RMerl/asuswrt-merlin.ng/wiki/User-scripts.

Since I did a lot of tests, I just put everything in a bash script and execute it manually. (I don't reboot my routers for months).

So, here is one example of mine for one of my AX58U:

#!/bin/sh

# This does not work, if 2G is up
# wl country ALL

# Settings for 2G
wl -i eth5 down
wl -i eth5 country ALL
wl -i eth5 country_abbrev_override OFF
wl -i eth5 regulatory 1
wl -i eth5 chanspec -c 3 -b 2 -w 40 -s 1
wl -i eth5 up
wl -i eth5 2g_rate auto
wl -i eth5 txpwr1 -o -m 1496

# settings for 5G
wl -i eth6 down
wl -i eth6 country ALL
wl -i eth6 country_abbrev_override OFF

# set 802.11d only and disable 802.11h
wl -i eth6 regulatory 1
wl -i eth6 spect 0

wl -i eth6 chanspec 36/160
wl -i eth6 up
wl -i eth6 5g_rate auto
wl -i eth6 txpwr1 -o -m 1496

anyway Just for information; i was checking some old tweaks for the AC68u transmission power and i came across a command that i didn't see used here "nvram set pa0maxpwr=708" it's strange because many nvram commands tried by users here come from that list of tweak commands that worked for the old 68u, this is one of them but i don't see it used, maybe for current devices it's not needed anymore i don't know

@Reeplosin
Well, it all depends on your router model and OS, driver (and also wl) version. On my AXE11000 and AX58U pa0maxpwr doesn't exist in NVRAM.

Since we don't have an official documentation by broadcom, it's a bit shooting in the dark... or to put it differently try & error :-/

If you find comands working for you -- please share :)

@pasko-zh What's funny, is that I do have China as an option:

# wl -i eth6 country list
Supported countries: country code and long name
#a	
AU	AUSTRALIA
CA	CANADA
CN	CHINA
DE	GERMANY
E0	
FR	FRANCE
GB	UNITED KINGDOM
JP	JAPAN
KR	KOREA, REPUBLIC OF
Q1	Q1
SG	SINGAPORE
TW	TAIWAN, REPUBLIC OF CHINA
US	UNITED STATES

Was this from your AX-58U?

I think the nvram controls the hardware limits/bars, and with iw you actually boost them (or force some overriding).

I'll try to test later this weekend, and adjust the README.md.

Thanks again!

Well, on my linux machines I use iw a lot. But here on asus merlin, I was only trying it a bit, and most things were not working

@francoism90 Let me know if shall test anything. Happy to support.

I'd list mine in response but seriously(!) the list is 268 lines.

Still can't get channels above 165, no matter which country I try.

To get the channels I think you have to change the chainspec

the command on my ac86u is "nvram set wl1_chanspec=161/80" on your device it will have to be something like "165/160" or something like that you will have to try

You can do it via NVRAM or via wl

You may need to select a different interface number, e.g., eth6 or so... On my AXE11000 I configured it like this:

# settings for 5G
wl -i eth7 down
wl -i eth7 country ALL
wl -i eth7 country_abbrev_override OFF
wl -i eth7 regulatory 1
wl -i eth7 spect 0
wl -i eth7 chanspec 165/160
wl -i eth7 up
wl -i eth7 5g_rate auto
wl -i eth7 txpwr1 -o -m 1496

Then

wl -i eth7 status
SSID:  I HIDE MINE HERE...
Mode: Managed   RSSI: 0 dBm     SNR: 0 dB       noise: -87 dBm  Channel: 165/160
BSSID: C8:7F:54:94:95:24        Capability: ESS RRM
Supported Rates: [ 6(b) 9 12 18 24(b) 36 48 54 ]
HE Capable:
        ....

NOTE! You also need a client supporting those channels. With Intel's adapter with theri stupid LAR, I had no chance!! I replaced my Intel AX-210 with Mediatek MT7922. It works under Win10 and Ubuntu:
