hAP ax3 - 5GHz channel not discoverable from MacBook Pro and Pixel 4a

Sat Feb 25, 2023 2:23 am

I used the Quick Set configuration, set the country correctly, but for some reason neither my MacBook Pro M1 (supports ax) and Pixel 4a (supports ac) see the 5GHz channel. They both find the 2.4GHz and use their highest supported standard (ax and n accordingly). Any suggestions?

This is the current config:

Check the status of Wi-Fi interface, by default it often goes DFS 10 minutes when staring, it will now allow connections before finishing DFS.
You can change it in the config to skip 10 min DFS or skip all DFS channels

It's set to skip 10 min cac:
.skip-dfs-channels=10min-cac

And from the WebFig UI:

Or do you mean something else?

Well, MikroTik support claims it work best on auto.
I have a different view, on auto my ax had a terrible performance.

Try the the example from doc: https://help.mikrotik.com/docs/display/ROS/WifiWave2

The way they use profiles is very handy. It improved my ax3 performance. I just added skip 10-min as you showed.

I’d also suggest not upgrading to 7.7 yet. First check the performance

Isn't that the default?
I remember that in my hap ax3 it was already like this...

With my macbook pro m1 is much faster with channels between 36 and 100

Remember that there are two DFS ranges, 10 minute (for meteorological radars) and 1 minute (for ATC radars). The 1 minute applies to pretty wide frequency range, so it's almost impossible to avoid it.

Now I'm about 8 meters from the hap ax3 with no walls, connection always perfect and stable.

As you can see, i always get the same download speed.
If I get closer to the router it goes even faster.

wow, I'd be happy whit your results

Can you share some details of your HW, config, country code and connection details?

What channel does router choose?

This is what I see in the WebFig interface under Status:
Channel 5500/ax/Ceee

How can I verify from the terminal?

You can check it here:
[admin@MikroTik] > interface/wifiwave2/monitor wifi1 
             state: running
           channel: 5720/ax/eeeC
  registered-peers: 2
  authorized-peers: 2
          tx-power: 23

[admin@MikroTik] > interface/wifiwave2/monitor wifi2
             state: running
           channel: 2437/ax/Ce
  registered-peers: 7
  authorized-peers: 7
          tx-power: 16

Thanks a lot for your data! I can see one big difference:
My CPU temp is higher than yours, it is currently 63 deg C vs 49 and CPU speed is lower, currently 864 vs 1320.

I need to check it with Support

Re: hAP ax3 - 5GHz channel not discoverable from MacBook Pro and Pixel 4a  [SOLVED]

Tue Feb 28, 2023 1:16 am

Solved by limiting the frequency to 5000-5450. The router selected 5260 which works (instead of 5500 that didn't work). They both are DFS channels so I'm not sure why would one be discovered quickly while the other not at all.

DFS channels between 5600 MHz and 5650 MHz are so called "weather" DFS channels which require scanning with duration of 10 minutes ... during which no transmission is allowed. So if there's no weather radar in your neighbourhood, WiFi might actually appear ... but after 10 minutes (which is forever when one wants to get things going).

Another possibility would be client not supporting those channels. Similar concept: many wifi clients don't support 2.4GHz channels 12, 13 and 14 unless they are set to country where those channels are legal (I've had an issue with smartphone LG G4 which wouldn't work with channel 13 AP until SIM card was inserted and from that phone learned it's in Europe and using ch. 13 is legal).

I see, but the chosen channel was 5500 MHz, I assume that was not the issue?

The country was set correctly. Maybe channel 100 (5500 MHz) is not supported in Israel but the router's software does not have the correct channel mapping for this country?

I don't know how exactly Israel mandates usage of WiFi, so your guess is as good as mine.

Checked it, allowed range is 5150-5350 and 5470-5725. I don't know the standard's details but if the channel width is 80 MHz and the center freq is 5500 it means it starts at 5460 which is outside the range. Just a guess though.

Israel. Wow, limited channels in 5GHz here, and low power ! (data from classic driver in ROS 7.7)
Nothing above 5320 (channel 64). 4 indoor-only channels, and 4 DFS channels.
(channels are 20MHz wide: (5180,5200,5220,5240)(5260-5280-5300-5320) 80MHz would be 5180/Ceee and 5260/Ceee.
And the "indoor" line is only available when installation is set to "indoor" or "any".

... if the channel width is 80 MHz and the center freq is 5500 it means it starts at 5460 which is outside the range.
Nope. Mikrotik shows frequency which is center frequency of Control channel. So clearly control channel was ftom 5490MHz to 5510MHz. The rest is a guess, but if channel layout was Ceee, then the 80MHz channel would span between 5490MHz and 5570MHz ... if channel layout was eeeC, then 80MHz channel would span 5430-5510MHz. But then it might opt for 40MHz only channel spanning either 5470-5510MHz or 5490-5530MHz. Or something else.

But then wifiwave2 could contain country limits which are actually invalid (but we can't check them because traditional command showing them doesn't work since 7.6). And if limits from legacy driver are correct (and other devices obey them), then it's only logical that devices ignored AP whike it was using illegal frequency channels.

Hi,

I have similar problem, When I do not chose country the radio power is at maximum I have best wifi 6 performace but the WIFI 5,4Ghz channel is too high and my TV Samsung 3 years old do not connect to this channel. When I chose my country the channel is lower and my TV can connec to 5,4Ghz

Re: hAP ax3 - 5GHz channel not discoverable from MacBook Pro and Pixel 4a

... if the channel width is 80 MHz and the center freq is 5500 it means it starts at 5460 which is outside the range.
Nope. Mikrotik shows frequency which is center frequency of Control channel. So clearly control channel was ftom 5490MHz to 5510MHz. The rest is a guess, but if channel layout was Ceee, then the 80MHz channel would span between 5490MHz and 5570MHz ... if channel layout was eeeC, then 80MHz channel would span 5430-5510MHz. But then it might opt for 40MHz only channel spanning either 5470-5510MHz or 5490-5530MHz. Or something else.

But then wifiwave2 could contain country limits which are actually invalid (but we can't check them because traditional command showing them doesn't work since 7.6). And if limits from legacy driver are correct (and other devices obey them), then it's only logical that devices ignored AP whike it was using illegal frequency channels.

Thank you for the detailed explanation! I remembered now that the Pixel 4a was purchased in the US, so it should not be limited to Israeli frequencies, and still it could not discover the router when it chose the 5500 channel.

Some MT models have specific US executions. (Chateau, SXT,LHG) mostly when mobile channels are involved. It is normally clearly documented if there is a US specific execution.
Like: https://mikrotik.com/product/rbdisc_5nd (check the freq ranges of the US version !!)

Region limitation for wifi frequencies, power, DFS, is set when the country or region is set in the config.

If in one physical region, you fill in another region, there might be problems with client devices that did set the correct or even yet another region, as only the common frequencies are usable.
With the region info as it is seen in MT, an Israeli client (set to region Israel) device will not detect wifi on 5500MHz+ channels.
(My DJI drone uses it's GPS info to set the correct region. )

The LG G4 I mentiobed in post #15 above got info about rough location from mobile network (MCC says it all).

So it doesn't really matter where devicecwas purchased (unless it's crippled to country speciffics), if it's truly "world" device it'll adjust to country regulations according to location information (and there are various location information sources).

Interesting point, you're right it can detect the location by SIM operator, GPS signal and more. Thanks!

SIM operator doesn't necessarily give current location (think roaming). So it's actually MCC of currenly used network (can even be the "emergency calls only" half-registered network, phone will be able to read MCC anyway).
