Oh, if the airport weather radar is close enough, in some cases due to atmospheric siatuations, the signal can be reflected back even if you dont have a line of site to it, and the router can pick it up. I also have a major airport in my vicinity which is blocked by a mountain, yet in some cases the radar signal can bounce back. This can also be measured with a spectrum analyzer. Sometimes they refer to this as a cloud duct effect.

After changing MODPARAMS.ath11k:=frame_mode=2 to MODPARAMS.ath11k:=frame_mode=1 WDS works fine!
Thank you!
(802.11s still doesn't work / as soon as a 802.11s network is up iPhone isn't connected to the internet anymore and Channel Analysis (lucy) keeps crashing)
Hello guys, tell me, I saw the structure ath11k_he_ru_tones_to_nl80211_he_ru_alloc (u16 ru_tones) in the sources, this is the definition of the number of resource units for devices, but not in the sources where they are distributed among the connected devices, who knows tell me. The main performance of the device is tied to the shellduler.
Little question: Does the IoT antenna work? I have an older snapshot running, r0-5432a90. And is there a benefit to the default 2,4ghz antenna/network?
It works, but it's better this way
Ath11
Wlan1 - 5 GHz
Wlan2 - 2.4ghz, wlan2.1 2.4ghz for iot
Ath10
Disable
Thanks for your answer.
Its kinda cryptic, but i guess you want to say that ath11, which offers wlan1(5ghz) and wlan 2 (2,4ghz) is more powerful than the ath10 (which ofc just has one antenna in contrast to ath11s 2,4ghz). Logical. So ath10 is just to lower the wifi standard for iot devices so you still can go for ax on ath11s 2,4ghz (some ppl claim iot devices dont like the new standards, wmm and so on). Thought theres maybe some other features or benefits i miss.
I understand you correct that i should create another 2,4ghz wifi with ath11 for iot? Didnt know this is even possible.

Yes, I did so and everything works great. about wmm etc. they can be disabled separately.
Hi all again! I just moved and changed ISPs and I have a some things to share:
Before, with my old ISP, I was only using a wan vlan to get an IP address but now my new ISP requires to use PPPoE + wan vlan to get both a ipv4 and ipv6 IP. With software and hardware offloading and packet steering I get max ~850Mb/s and with the ISP router I get 1Gb/s. I didn't have time to check but I think that the CPU is getting maxed like others reported.
I suppose that using a wan vlan + PPPoE is the worst case scenario to get a connection because the router has to work a lot, so if anyone wants me to test something I'm available.
Also, I found out that for some reason if you do a channel analysis with the iot radio the iot light turns on despite what you have configured in the led settings.
All of that was with robimarko 2022-07-08
Edit:
Also I have to report that, at the moment, I could not get the router to use high DFS channels because is detecting a radar (?). I can see others devices using the channels that I'm getting problems on and I don't really know why.
Edit 2:
My new ISP (digi) seems to use ipv6 as the primary way to get to the internet so i don't know if it helps or harms the speed and load on the router. I remember reading about ipv6 offload not working very well on openwrt.
Could you try a previous build?
I'm also getting radar detection and before I never got radar detection.
I my case with airport at 4km, I could really get hit by radar, even if it's and exeption. Anyway I'm back to the previous build to see how that goes.
Do you have any airport nearby?
Regarding PPPoE cpu load, search for @dchard last posts about that and also try the IRQ optimizations he uses.

I will test a couple of past builds tomorrow as I don't have any free time left, but as soon as I do it I'll report back.
Nope, the nearest is at 13km (I'm in a big city)
Can you link to them? I can not find the one that you are referring to. Thanks!!

Here the @dchard irq optimization, correct me if i'm wrong
#assign 4 rx interrupts to each cores
echo 8 > /proc/irq/50/smp_affinity
echo 4 > /proc/irq/51/smp_affinity
echo 2 > /proc/irq/52/smp_affinity
echo 1 > /proc/irq/53/smp_affinity
#assign 3 tcl completions to 3 CPUs
echo 4 > /proc/irq/73/smp_affinity
echo 2 > /proc/irq/74/smp_affinity
echo 1 > /proc/irq/75/smp_affinity

I tried the 2 builds before the last one and I got the same result. Seems like I have a radar signal near me and I can not use the DFS channels :(.
The WIFIs that are on the those channels have a custom name so I believe that the people that configured them seem to know enough to change the WiFi driver to a country that does not have the DFS restriction and avoid the regulations.
Thanks, that's good to know, because mine is rare and random, like once in 2 days in last build, but never happened in previous builds.

@robimarko can correct me if I am wrong, but as the radar signals are detected by the firmware/BB, which receives only the DFS list from the driver via the BDF files, I highly doubt that a change in the last two builds is causing this. Of course if you select a country illegally which does not apply the regulations, that is a different story. Or you somehow hack the BDF or apply incorrect BDF.
I am using the latest build, correct country selection, DFS list is per the country regulations, I have a weather radar on the used (160MHz) channel, yet I see no radar detect alarms. Very rarely in certain atmospheric conditions, I can get a radar detect, maybe 1-2 a year as the radar is blocked by a mountain by default.

My only explanation would be a rare and random radar reflection in the last few days that coincided with the last build. Time will tell.
Airport is blocked behind a small ground elevation and a lot of buildings.
I never paid attention to that before ax3600.
I remember reading here that US country was ok for testing and I always selected that in ax3600 (because of BDF), but I'm in EU.
I'm using the correct power and channels for my country.
I got 2x ax3600 to get a good coverage and I don't like, neither need high power wifi near me.
From the two routers with same build, only one is getting the radar detection in 5Ghz, chan 116, 80Mhz, country US.
Does not matter if you use the correct power and channels if you select US and there is no DFS working on the frequency where it should. You can never know if the only radar is the one next to the airport, your national weather service or the military or even private weather operators can also have radars in your vicinity. You need to make sure DFS is active where it needs to be, and if it detecst a radar that means you cannot use that channel. Simple as this.

have you tried to move to a higher channel ... i seem to remember that on the 80mhz above the 140 channel dfs is not checked...
@dchard
I did compare US with my country.
For (5470 - 5725 @ 160), both support DFS.
I'm using US and getting radar detection.
Still I agree I should be using my country, but I think incorrect BDF for my country is removing some allowed freqs.
The difference is, with EU (or my country) I can use chan100@160Mhz, but I can't use chan116@80Mhz. I least is what I remember when I tried it.
I don't want to use chan100@160Mhz, but want to use chan116@80Mhz instead.
EDIT: I just tried this again, I selected my country in all radios and rebooted, now I can select chan116@80Mhz that I wanted. Nice.
@rmandrad
I can use another channel, I have another ax3600 in another room, with same FW build, that never got hit by radar detection.
That is correct, no FW or BDF changes occured recently and neither driver changes

The previous test was last year, when I bought ax3600.
I retested my country (in EU) AX 5Ghz radio and I can use all the allowed freq., chan36@160Mhz, chan100@160Mhz or their 80Mhz parts. I didn't looked at power or other details. Nice.
Looking at a few EU countries in db.txt, the allowed 5Ghz AX freqs. are the same. Probably EU directives.
EDIT:
I'm now using my country code for all 3 radios.
iw reg get shows the configured country code for global, phy#2 and phy#1, but phy#0 is always country US: DFS-FCC. Trying other EU country codes gives the same result.
Is phy#0 the IOT radio?
