@Birillo You will probably see better performance when the 2.1.4 beta firmware. https://community.tp-link.com/en/business/forum/topic/615998 Make sure you are on the latest controller OC200 version...

@DaKings Sounds like TP-link is using Suricata for their IPS/IDS on their routers... which they do keep their own lists updated. TP-Link trying to reinvent the wheel isn't something I can see them...

@TalkiToaster mDNS across VLAN's have always been flaky beyond any vendor I've ever used. Especially casting to another device... I think it also depends on the casting device too. My Samsung TV...

@AhmetAkkaya At this point... I wouldn't put Tik and especially PFsense up as "competitors"... That's comparing Apples to a Watermelon.

@MR.S I think this will be a license base thing versus a "free" version. Sounds like the Pro line will get some high-end features versus the standard Omada Product line. Kinda sounds like Meraki...

@PeterAl Have you tried using the copper port as a WAN and see if it holds? Just for a test.
