i have the x60 3000 decos , Created the WIFI Deco

they had internet connection but then i changed the network topo

 I had 2 wifi routers 

First Topology:

first when i set them up, first router ip  192.168.40.0 /24 subnet

it was Main deco connected to Wifi router

Second Topology:

I removed the wifi router connected to the Main Deco

connected it to Cisco Switch which had DHCP server pool 192.168.40.0/24  

Switch have 2 Vlans  192.168.8.0/24  and 192.168.40./24

The Switch connected to router 192.168.8.1 as default gateway  

both VLans have Ip routing enabled

when i connect my phone to the Deco wifi, i can access the internet no problem

but my Decos still have red light

and when i access Deco app it's cant find them when i connect to Deco Wifi

i tried another thing connecting to Deco wifi and then connect to plex server from my phone and it worked no problem

so its Not LAN issue only WAN am guessing for the Decos ONLY, since i can have internet access when i use Deco wifi but the Decos still RED
