It's worth noting that I have wired VLAN on the main router with no issues, this is specifically on a node that supports it, but with GNP VLAN clients losing connectivity on the specific node when in use.There's a few people here, myself included, who've used managed switches to put wired devices in a GNP VLAN because of AiMesh nodes that don't support wired VLAN tagging (only my main router can do that ). I can't speak for those other people but I have not experienced any client dropouts (wired or wireless) like what's being described, so I think that's solid evidence of it being something about the Asus hardware doing the wired tagging and not a result of having wired clients in the VLANs.
