I have the same setup... One M5 and two M4 units. Now i have all the options i need and it seems to work good.

Aha thanks will check it when i am home

How can you see the cpu load on the deco? Curious to check mine.

I have a set of 2 M4 and i just bought 1 M5 to get some extra range. I put the M5 as master and the 2 M4 as slave devices. Now i can change the LAN IP and also the DHCP range. So the M5 can do it but...

Well first the scope has to be configurable. Then also with exclusion ranges. For example i want my dhcp scope from 100-200 but certain devices i want to have a reservation like .10 or . 253 So...

Would like some features in the M4. Change LAN IP and DHCP Pool Assign IP adresses outside DHCP pool to reservations.
