mt7622 unstable on 23.05, especially when using 802.1x dynamic VLANs

[enmaskarado]

I have no problem using my normal 2.4 Ghz Wifi (MT7620), except that it's very slow (around 16mbit/s), but I think that's a different issue

Unrelated, but try downgrading WPA3 to pure WPA2, or disabling MFP on WPA2. MT7620 doesn't have HW acceleration for MFP and software emulation caps the max speed to ~18Mbps.

I have similar instabilities with MT7610E using the 5Ghz radio/ AC mode.
I tried regular WPA2 and WPA3 and can confirm that clients get assigned correct IPv4/6 addresses and can ping internal IPs but not external ones.
Regular TCP traffic is also not working for me.

My router is a TP-Link Archer C2 v1 and i am on OpenWRT 23.05.2.

I am also thinking about a downgrade back to OpenWRT 22.03...

Perhaps you're facing openwrt/openwrt#11650?

Did you find any fix?

Unfortunately not yet, but I posted my problems in the forums: https://forum.openwrt.org/t/tp-link-archer-c2-v1-on-23-05-no-internet-coming-through-5ghz-wifi-slow-2-4-ghz

Ahh thanks for the explanation. I will try it when I'm back home and see if it makes a difference.

Edit : yes this really made a difference, i now have around 45 MBits throughput.
