Hello Team,
I’m using a MikroTik NetMetal AX (L23UGSR-5HaxD2HaxD) with RouterOS v7.19.1 and the wifi2 driver, and I’m facing the following two issues:
1-No Available 5GHz Channels
I’m trying to set up a point-to-point (PTP) link using 5745 MHz or 5500 MHz , but receive:
# no available channels
#My setup:
Interface: * wifi2RouterOS: * 7.19.1Country: * Iraq (also tested with united states)Mode: * AP
/interface/wifi set wifi2 \
channel.band=5ghz-ax \
channel.frequency=5745 \
channel.skip-dfs-channels=none \
channel.width=20mhz \
channel.country=iraq \
mode=ap \
ssid=P2P-Test \
tx-chains=0,1 configuration.chains=0,1
Other attempts:
channel/print → returns nothingcountry=no_country_set → not available in wifi
2-Client Radio Name Not Showing
When devices connect to this AP:
/interface/wifi/registration-table/print shows clients,but their radio-name field is empty or missing
This makes it harder to track which station is which (especially in a multi-point or diagnostic setup).
Why are no 5GHz channels available , even DFS, despite being listed in documentation?
How can I check for available frequencies?
Is the radio-name bug a known limitation of wifi?
Is there a workaround or expected fix?
Thank you in advance. I appreciate any guidance or suggestions from MikroTik staff or the community.

Well…
on your device wifi1 is the 5ghz radio, wifi2 is 2ghz (at least I think…)
“none” is not valid for skip-dfs, “disabled” is
“iraq” is not valid for country, “Iraq” is
Otherwise should work. How are you not getting errors?
Sorry it was typo issue,
Country is Iraq, dfs is disabled, and wifi1 is 2.4, wifi2 is 5 Ghz
Netmetal is outdoor device.
My mistake on wifi1/2.
The frequencies are available for outdoor in both countries, but they are dfs.
Maybe the frequency is unavailable because of dfs? This should show up in the logs. Maybe enable wireless debug messages?
in debug shows below
and also show this in wifi2
That makes sense. 5520 is a dfs channel, and you selected to skip them.
Anyway, return to defaults, even reset the device to default. Make your changes one by one and see which one causes the conflict in your config
for now i made it allm i returned back to disabled see below
Basically you are saying: don’t use DFS channels…use frequency 5520 (which is a DFS channel). What are you expecting!?
Leave frequency empty to get it to work, or set consistent settings. If left empty you will see what frequency the device chooses (I would expect a 2.4GHz channel frequency).
Funny as it seems this is the first AX device I see where wifi2 is 5GHz and wifi1 is 2.4GHz.
FYI, yes Wifi1 is 2.4 and wifi2 is 5.0
Regarding the skipping DFS as i mentioned it was for test,
Prev (5220): ~40M to 75M
is there any idea how to select the freq that i want? previusly there was no_country_set and i was able to select any freq i want, not there is no option like that so i must check one-by-one
OMG…I use the wAP AX…CAPsMAN didn’t make me realize.
With this command you can see all allowed frequencies:/interface/wifi/radio/reg-info country=Iraq
On my wAP AX it shows:
/interface/wifi/radio/reg-info country=Iraq
Outdoor is (by regulations) limited to 5490-5710/30dBm/160MHz/dfs.
Can you please do an export instead of posting screen shots?
/interface/wifi export
Find below
/interface wifi
set [ find default-name=wifi2 ] channel.band=5ghz-ac .skip-dfs-channels=\
disabled .width=20/40/80mhz configuration.chains=0,1 .country=\
"Iraq" .mode=ap .ssid=P2P-TEST .tx-chains=0,1 disabled=no
Can you change it to something like this:
/interface wifi channel
add band=5ghz-ax disabled=no frequency=5500 name=CHAN-5G width=20/40/80mhz
/interface wifi
set [ find default-name=wifi2 ] channel=CHAN-5G configuration.country=Iraq .mode=ap .ssid=P2P-TEST disabled=no
Correct you don’t use security?
/interface wifi security
add authentication-types=wpa2-psk,wpa3-psk disabled=no name=SEC wps=disable
/interface wifi
set [ find default-name=wifi2 ] channel=CHAN-5G configuration.country=Iraq .mode=ap .ssid=P2P-TEST disabled=no security=SEC
Personal preference (next step would be adding configuration sections), makes it les complex to adjust.
Same issue
/interface wifi channel
add band=5ghz-ax disabled=no frequency=5500 name=CHAN-5G width=20/40/80mhz
/interface wifi
# no available channels
set [ find default-name=wifi2 ] channel=CHAN-5G configuration.chains=0,1 \
.country=Iraq .distance=3 .mode=ap .ssid=P2P-TEST .tx-chains=0,1 disabled=\
no
Chains for Anntenna not for Not Available Channels

Does it show a “DFS scan in progress” comment when you change any setting? To me it seems like 5500 is just not available and you only specified one frequency so it can’t select any other channel.
