I'm not choosing any DFS channels and I don't even get the option to select one b/c I have 160Mhz hard-coded. Otherwise, my 2 AX devices only connect at 80mhz. Do you have an AIMesh client?

Yes, I have an AiMesh client node... see my signature.

You are setting a non-DFS control channel, but notice that your log entries are scanning for 160MHz bw... to use 160MHz bw, it must use DFS channels/radio spectrum in the U-NII-2a band. I was wondering if the log entries have anything to do with you not being able to select 2a band channels... if those DFS channels are missing for you, are they also missing for the scanning process. Surely your AX node supports the 2a band(?)... why would an AX router be so hobbled as to not support the 2a band... WiFI6 is hobbled enough as it is with only two 160MHz options and only one of those able to support legacy clients rquiring non-DFS control channels.

Well the AX55 (my mesh client) is at the bottom end of the Asus line. If I remove it as AIMesh client, then my 86U get DFS channels back including when I hard-code 160Mhz. My wireless is interesting (I think). It's checking 36 for radar but 36 isn't a DFS channel, right?

You should stick with 80MHz.

Your WLog indicates cleared for 36/160 using DFS channels, and you have ax 160MHZ client connections. I guess your AX node is removed/not one of them.

Nope! and I didn't buy. We get them free from our internet provider as part of our service contract, so I got 3 of them. Tried it out as main router and immediately bumped it up to 86U (after reading up in this forum and site). AX55 and 256MB RAM is so under-spec'd. So many out of memory errors if I dared try anything like AIProtection., site history, etc.

My internet is 500/500 so you're probably right that 160Mhz isn't doing anything for me except make me happy when I look at the wireless log, lol.
 
With this firmware my 86U no longer shows or support any DFS channels... as soon as I add my AX55 as an AIMesh client. This wasn't the case in prior releases. Is it the same for everyone else? Surely, I'm not the only one w/an 86U and a lower-end AX AIMesh client. I can't remember, does the AX55 support DFS channels? And also, my log is filled completely with this set of errors repeating every half hour or so:

Your AX55 does not do DFS channels. It only has 20/40/80 MHz bandwidth. Therefore when you add it as an AiMesh node the AX86U is restricted to the channels the node can do. At least that is my experience with adding an AC66U_B1 as a node.
 
Well the AX55 (my mesh client) is at the bottom end of the Asus line. If I remove it as AIMesh client, then my 86U get DFS channels back including when I hard-code 160Mhz. My wireless is interesting (I think). It's checking 36 for radar but 36 isn't a DFS channel, right?

Right, ch 36 is not DFS but with 160 MHz set the router still has to clear for RADAR as the 160 MHz pushes into the DFS channels. If you are in an area where there is RADAR traffic you are better off to use 20-40-80-160 MHz. Then when the router detects radar it can go back to 80 MHz which will not use DFS channels and keep working. With 160 MHz set the 5 GHz band will be off for a few minutes on router reboot until it clears for RADAR.
 
Your AX55 does not do DFS channels. It only has 20/40/80 MHz bandwidth. Therefore when you add it as an AiMesh node the AX86U is restricted to the channels the node can do. At least that is my experience with adding an AC66U_B1 as a node.

Understood, but this wasn't the case prior to the very recent firmware updates (both 86U and AX55 got them). Previously, I could see and set 86U DFS channels when AX55 is AIMesh client. Now no DFS allowed on 86U with AX55 AIMesh. I guess I could try setting AX55 to AP rather than AIMesh and see what happens.

Primary channel: 36
HT Capabilities: 40Mhz SGI20 SGI40

Auto has select channel 36 but also using channel 50 (which is DFS, right?) due to my 2 AX clients. What is channel 50? It's not even listed as an available channel or DFS channel also in log:

DFS status: state In-Service Monitoring(ISM) time elapsed 126000ms radar channel cleared by DFS channel 36/160 (0xE832)

These FCC-US Unlicensed Spectrum graphics show the center channel (radio frequency) for each bandwidth. Ch 50 is the center frequency (aka channel) for 160MHz bw across the N-NII-1,2a bands... half non-DFS channels, half-DFS channels... the only WiFi6 option for 160MHz bw using a non-DFS control channnel, 36-48.

Your log shows control channel 36 and bandwidth 160, 36/160. Your router should be broadcasting a 36/160 WLAN... presumably your AX55 node is broadcasting a 36/80 WLAN since it presumably can't do DFS channels 52-64.

would everyone recommend adguard to block utube adds with the new Assign a DNS feature?
 
No, not everyone would. You do mean YouTube, correct?
 
I cannot select DFS control channels 120,124,128. This makes me wonder if this firmware permits a 160MHz bw connection in the U-NII-2c band, spanning channels 100-128(?).

You can't block YouTube ads with DNS-based ad-blockers. Use uBlock Origin browser extension.

Yes youtube, and mainly for for the TV app. I thought that the global dns settings from the router would help.

I had no idea about the free Adguard DNS servers until this firmware release added the list of DNS servers. For me, it's the greatest thing ever -- whole home ad blocking for every device. I've disabled AdBlock browser extensions and AdGuard app on Android devices. I pay for YouTube Premium/YT Music so no ads in those apps.

It was very good of ASUS to include/highlight these. I'm beyond content filtering, but many home networks will use it.
