On TP-Link Archer c60 v3 after sysupgrade to 24.10.1 the 5GHz WiFi adapter disappears from the Interfaces/Devices and Wireless menus.
Unfortunately i won't be able to provide more precise information on the problem for now, as this is also one of the devices, affected by the wget/libustream-mbedtls incompatibility in 24.10.1, that breaks opkg. Also it has only 8MB flash. After bricking the installation when my attempt to replace mbedtls with wolfssl was prevented by the lack of space (no more https uhttpd/ssh) i had to downgrade. May test it more extensively in few days, after finding replacement router.
