AX3600 and AX6 wifi6 not working in stable release - OpenWrt 23.05.2

Installing and Using OpenWrt
1

I have 23.05.2 on both and If I have AX in "Operating frequency" the devices cannot see the wifi network.
Only after selecting AC its back to working condition.

23.05.2 works OK for me on an AX3600, in AX mode on both the 2.4GHz and 5GHz radios.

Some ideas:
You have 2.4GHz/radio1 set to automatic channel. Try choosing one manually.

You have 5GHz/radio0 set to 160MHz. You'll probably find it takes a long time to do an initial DFS scan and/or later gets knocked offline during operation. Try HE80/80MHz and again, specify a manual channel. Make sure your county code is set properly, and run 'iw list' to see what options look good. If you're lucky (and free from neighbors), try a non-DFS (no "radar detection") channel with > +20dBm, bearing in mind that HE80 will need four such adjacent channels to work. For me, that's channel 36 @ +23dBm only - the only other non-DFS channels open to me are +13dBm.

Edit: while on the topic, don't blindly choose the maximum available power on either of the AX radios. Back it off and check if the link rate improves. As is common, the AX3600 PA has best linearity/noise when not run flat-out. I don't know where the fall-off occurs in practice (dBi, overall gain), but e.g. the 5GHz PA is only rated for HE80 SNR up to +18dBm: https://www.qorvo.com/products/p/QPF4588

I had to reset them to factory (openwrt) and it started to work again.
