Hi,

Happy New Year! 

I have recently moved to Omada ER7212PC and two EAP772 AP from Synology (after it failed). 

Since then, I have been trying to troubleshoot my Sonos speakers (Play1 x 2, Play3 x 2, Playbar, Beam (gen 1)) on WIFI network share with my iPhones and iPads.

I only have single LAN.

Then I have found this thread https://community.tp-link.com/en/home/forum/topic/718708 and update my settings.

I am reluctant to turn on UPnP. Is this really required?

Even with UPnP on, it seems to work better so far than off. Can I port forward instead?

Anything else should updated?

Thanks heaps~
