@RMerlin
As always your code and firmware is beyond excellent and much appreciated. I've been using your firmware exclusively for years and wouldn't consider anything else. I flashed to 386.1. All seems fine with one glaring and troubling item.
First, pertinents about my config:
RT-AC5300
Dual WAN with failover. WAN+Eth1
I have my IoT devices on guest wifi-1
I have my LAN internal devices routed through a VLAN/Switch then to LAN3 on the router.
Other internals on guest2.
This config was running fine until I upgraded from 384.19.
Now, when I look at my network map, I see the IoT devices from guest wifi-1 showing as ethernet (wired) connected along side of my LAN connected devices.
I can ping the guest-1 wifi devices 192.168.101.x from my LAN 192.168.2.x. Access Intranet is off and I tried toggling it on an off to be sure.
I then did a complete reset to factory, uploaded the firmware and reconfigured everything from scratch to be sure there wasn't a corrupted config parameter being introduced from the upgrade.
I rolled back to 384.19 to be safe until I can figure out the issue.
Thanks for any assistance.
