Hi all

I've read through multiple threads & followed the app support but no joy. I set up the Deco M4R Ver 2.0 which worked well downstairs in the house, but very limited upstairs due to mass concrete walls and floors. 

Modem - router - main deco - 3x remote deco's. 

My modem is located in the garage and connected via cat6 to the house.

However there isn't enough ports on the router to feed the house (I've cat6's feeding each room from the router location). Plus with the above set up, I've no WiFi in the garage.

So, my new set up is:

Modem - TP link 8 port TL-SG108 - feed to garage wifi (working well) and house - TP Link 16 port switch TL-SG1016D - main deco (connected via cat6 to a wall port). That's where the problems start. The main deco now won't connect to the Internet despite using the same port and cable as before. 

I've changed ports, changed cables, changed deco's (I bought 4), rebooted / restarted the deco's, cleared the previous saved network etc etc.

The switches seem to be working fine. I've confirmed Internet in the house wall ports. 

When setting up the main deco, all works fine up until the "Setting up your network" step. The LED turns from blue to red and cannot make any progress from there. 

Any ideas?

Thanks in advance
