I use a nodemcu which is permanently attached to my router

According to the description from this page you can't run a 160MHz wide radio on IPQ8174: http://www.bitswrt.com/11AX
Males sense, however vlan is completely dead doesn't work
I'm using the latest snapshot v1 firmware. I got two questions.
- I only have radio0 and radio1, not radio2. Is this normal?
- I cannot connect to the 5GHz AP on radio0. The SSID shows up but I cannot connect into it.
My understanding that this is the current state of the upstreamed BDF. I think folks are still trying to work out what the best one to use is.
Thanks. I've managed to solve my problems by using the firmware here as mentioned in above posts: https://github.com/testuser7/openwrt/releases.
Has anyone had issues with an MX4200 V1 crashing regularly due to running out of memory?

Not after recent updates
I have prepared a new test build without removing regdomain from the calibration data. I want to make sure this change is necessary for proper operation before preparing the PR.
The update must be performed without saving the settings (sysupgrade -n).
Please check WiFi operation for different countries (US, GB, CN).
Are there specific settings which will cause problems on upgrade? I've got quite bit configured that I'd ideally not have to reconfigure manually again (DAWN, 802.11r, etc.)
You need to remove /lib/firmware/ath11k/IPQ8074/hw2.0/cal-ahb-c000000.wifi.bin and restart router after update.
But after sysupgrade you will lose your settings anyway due to the two rootfs_data partitions used.

Restoring a backup of the config should be safe after the sysupgrade though?
I think so.
But if you perform a second sysupgrade while keeping the configuration, you will probably return to the current state 
Think I'm back up and running on my V2:

Anything you'd like testing or just generally see how it goes and/or speedtests?
What country did you set in this case?
Tx-Power: 5 dBm is not correct value.
They're set to GB in Luci.
Am I being very silly or are you not actually calling the ath11k_remove_regdomain function in that build?
Nope you are not silly, it's been hashed out
Right, I misread the previous post. This build is suppose to not have regdomain removed. And we're aiming to confirm that we should be removing the regdomain? Which the fact that my TX power is wrong suggests is the case?
I set mine to US country code. The 5Ghz signal is very weak, as my Tenbay KuWfi T-MB5EU 5ghz is strong than my MX4200.
