It takes time for SSID to be shown when MAC Filter is enabled

[bahtsiz_bedevi]

I'm using Whitelisted MAC filter and phone clients are set to use device's mac address (not randomized MAC address)

If I enable MAC filter in OpenWRT, sometimes it takes several minutes for SSID to be shown in phones's wifi scan list. Is there a solution for that?

If Android 8+:

@lleachii

Androids greater than 8, as I recall - have changed their scan settings. In fact, to use advanced Wi-Fi analyzer apps, you have to now enable Developer Options to change that setting. See: https://developer.android.com/topic/performance/vitals/bg-wifi

The post you linked actually described why the [known - intended] behavior occurs and how to seek a "solution". Your wording seemed to overlook that fact.

@mk24

it changed in the code sometime last year. I don't know if it is an OpenWrt specific patch or something generally added to hostapd upstream.

@mk24 - did you ever find out if it was just OpenWrt, or was it an upstream change to hostapd?
