Asus/Merlin Noob: Lots of Kernel entries in sys log

EagleCity

New Around Here
Hi there. I'm relatively new to the world of Asus routers and Merlin, so please be gentle.

I've been running an AX86U for about 5 months now, currently on 386.3_2. I absolutely love it. Came home after spending a week away from the house and after about 24 hours I wasn't getting anything to connect. Had full wifi signal, but websites weren't loading on any of our devices. On a whim- I changed out AdGuard's DNS for Cloudflare in the router and that seemed to fix things, however, I'm now seeing a ton of activity in the sys log.

I've reboooted a few times and re-installed the firmware, but am still seeing these types of entries. Connectivity seems to be fine, but I'm concerned about what I'm seeing now. Any ideas on a fix based on the below, or what this may be indicating?

After the full reset, how did you set up the router?

Manually reconfigured everything. Set up new SSID + pw, enabled DNS privacy. Am pretty much on default config.
Then slowly reconnected devices to see if there was something on the network causing the issue and didn't notice anything out of the ordinary.

Let it run overnight and there are 1k+ kernel entries in the log that are now all over the place. Seeing a bunch of things like this now in addition to what I was previously getting

Code:

My guess is that these messages are caused by one specific client device. You could try powering off devices one at a time until you find it. This is a bit of a long shot but try setting the 5GHz band to a fixed channel and 80MHz bandwidth.

Those messages are the normal "syslog noise".

Overnight there were a lot of Kernal entries that seem to likely be caused by our iPhones. Both my wife and I have iPhone 13's.

On my iPhone- I see a Privacy Warning now when connected to the network. Never had this before.

Privacy Warning
This network is blocking encrypted DNS traffic



Here are the WAN DNS settings. Am not using DNSFilter.

Based on the above- my theory is that this is somehow DNS related.

This all started when a few days ago I couldn't connect to any websites. The network was up, devices were connected, everything fine with the modem. But our phones and computers couldn't get anything to load.

I was using AdGuard (with DNS Privacy), as I had been for the last 6 months. I switched over to Cloudflare and magically everything started working. 2 days later and I still can't get adguard working on the router. It seems like it's unable to resolve domains- if I ping an ip address it seems to be fine.

Could just be a coincidence, but I'm leaning towards something DNS related in the router.

Update! I've kept both my and my wife's iPhones off wifi for the last 24 hours, and we haven't seen a single one of these Kernel entries since:

Code:
kernel: CONSOLE: 153161.885 ppr_get_vht_mcs: Failed ppr_t:0045b420 BW:2 Nss:1 mode:0 TX_Chain:4 rateset:00175f3c

I'm wondering what on the iPhone could be causing this... could it be the phone switching between 2.4 and 5g bands?
