GL-iNet Flint 3 (GL-BE9300) WiFi MLO device discovery issues

Routers

I have an issue with my Flint 3 and MLO active that some devices are not reachable in the network anymore from an MLO device.

I have a LG soundbar (Google Cast) connected to the WIFI 5Ghz and an iPhone 17 connected to MLO. The phone can’t find the soundbar in the google Home or LG app, using an iPad connected to the same WiFi wihtout MLO the soundbar is reachable.

When I deactivate MLO also the phone can reach the soundbar.

I’m using the latest firmware version 4.8.3 on the Flint 3

Hi

It is possible that some devices have poor support for multicast on MLO Wi-Fi .

Please try to SSH into the router and execute the following commands to enable the "Multicast to Unicast" feature to see if it resolves the issue:

uci set wireless.wifi2g.multicast_to_unicast_all='1'
uci set wireless.wifi5g.multicast_to_unicast_all='1'
uci set wireless.wifi6g.multicast_to_unicast_all='1'
uci set wireless.wlanmld2g.multicast_to_unicast_all='1'
uci set wireless.wlanmld5g.multicast_to_unicast_all='1'
uci set wireless.wlanmld6g.multicast_to_unicast_all='1'

uci commit 

reboot

Additionally, please navigate to Admin Panel -> Network -> IGMP Snooping and enable the feature to see if it helps.
