If I compile hostapd with wolfssl, the Luci web interface shows only the 5G wifi as active and shows connected stations. The 2.4G wifi is shown in gray. On the network->wireless page, the radio for 2.4G is marked as 'Device is not active'. The SSID's are marked as 'disabled'. This occurs on a ASUS AX53U and a TP-Link WDR3600 router. The 2.4G wifi is running and stations are connected. Hostapd is build with the internal radius server activated. The setup for 2.4G is 8 wifi's with encryption wpa3, wpa3-mixed, sae and sae-mixed.

If I execute 'ubus call luci-rpc getWirelessDevices' for the openssl and wolfssl build, this is the difference (shortened):

The wolfssl build detects the 2.4G as not up, in the interface section 'ifname' and the the complete 'iwinfo' part is missing. If I call iwinfo directly, it shows the full output for both builds (some values are different).
