Wireless roaming

Folks
I am upgrading my older home dumb access points (all openwrt, and all using vlan (IOT, and LAN)).

I noticed that most of them, if not all, are using wpad-basic-mbedtls.

Earlier I used to replace wpad-basic with wpad-openssl.

For wireless fast roaming, should I upgrade this to wpad-openssl (or wpad-wolfssl)? Or just leave it to wpad-basic-mbedtls.

Much appreciate.
