#KRACK fix in 3.8.4 breaks Chromecast & AllPlay?

So my Chromecast v2 recently stopped working (my tablet couldn’t see it anymore, but the Chromecast appears to works normally otherwise), and also my Panasonic SC-ALL2 wireless speakers (again, clients couldn’t connect, but everything else OK?).

I made the following changes, after which everything seemed to be back to normal.

uci add wireless.@wifi-iface[0].wpa_disable_eapol_key_retries=‘0’
uci add wireless.@wifi-iface[1].wpa_disable_eapol_key_retries=‘0’
uci commit

I write this so other people may not pull their hair out, like I have been doing…
