That’s amazing I had it working for a while also.
Are you using the official OpenWRT or the developer build?
Does it get the speeds that the system is designed for?

I still have no 2.4 with the snapshot dated 2024-07-09 07:46:54 
2.4 radio shows as:
radio1
Generic unknown
Device is not active
I returned my Archer A9 and picked up an Archer C7 it works perfectly and its more affordable
Though it is 23.05.1, this has been working well for me:
Feel free to try out this build 
Hello, It's working really well. But can you add wireguard with its gui to it please to the build? Or make it work with downloading apps?
Thanks!
cant add sqm and other packages in this build. It says, "The installed version of package kernel is not compatible, require 5.15.164-1-da89f936… while 5.15.164-1-6ec88753… is installed."
Need help please.
A new build is live! 
@Raven993 @ricebox You both can give it a try now. Do let me know how it works out

I can't get the wifi speeds to work anywhere near what they were with stock firmware, was over 300Mbps, now maxing out around 70. Other than that it seems to be working fine, both bands are indeed working.

You'll want to use 40MHz channel width, or maybe even 80MHz.
And here, you may want to consider 40MHz channels.
I receommend against using sae-mixed as there are many client devices that just don't work properly. Stick to purely WPA2 or WPA3, not mixed mode.
Upgrading to a stable release might also be a good idea.
Since firmware-selector seems down, use https://downloads.openwrt.org/releases/23.05.4/targets/ath79/generic/
Unfortunately that yielded only about 20Mbps improvement.
Tried that, but 2.4Ghz isn't supported in the stable release, which isn't worth it. Time to go back to stock I guess
Couldn't find any documentation but J2 on the board is a 3.3v serial port with pins TX, RX, GND, and 3.3V, and 115200 baud rate
80MHz works and gets me about 300mbps.
When set to 160MHz my mt7921e nic cannot find it.
I Used the online tool here - Online tool to convert TP-Link stock firmwares to sysupgrade-compatible images Then force flashed the sysupgrade image through the openwrt web UI.
any chance you could integrate the 2.4 drivers in latest 24.10.0-rc5 ? Wanted to give it a try but don't have the know how to compile myself. Your 23.04.5 one was really stable, but with reduced speed of 200 ish in a good day for 300 mbps cable connection.
it's not just compiling, the patch will not work with new kernel without changes.
I also keep getting errors with IOT devices
hostapd: phy1-ap0: AP-STA-POSSIBLE-PSK-MISMATCH
Looks like it was fixed in snapshot [https://www.reddit.com/r/openwrt/comments/1g71yk3/apstapossiblepskmismatch_cannot_properly_join_one/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button&rdt=36418]
but oh well
