@Jashua_Bat2022 Also check if you enable the "Leagl DHCP server" option on network->LAN settings.

@Damasu I have EAP225-outdoor and one of the SSIDs can work well with untag VLAN. But my switch/router are both Omada and all of them are managed by the controller.

@Bertolechi "... cannot see each othe " means these devices cannot ping to each other? There are many things maybe related to this issue, like IGMP, FTP service port, SMB protocol...But if you can...

@JoeSea It's the ER605 doing routing on your local network VLANs, not the switch. It's ahrd to believe it is related to the switch firmware... Make sure there is no gateway ACL on your controller,...

@thisisliam Try policy routing on Location B router settings. Source IP is the IP group for all LAN except the specified device. Destination choose IP group any. WAN Interface choose the WAN port...

@WadeOx I also hope so. I saw somewhere that ER605 will receive a big update early 2023, let's see what will happen
