One of the ethernet ports on my main Deco has failed (the other 2 still work).  Is this common?  I'm trying to decide if it's worth getting a replacement under warranty, or just living with it as I only use 2 ports on 2 of my 5 Decos and none on the other 3.  After it happenned I checked all the ports on all 5 units and I found 1 port on unit that was not working.  So I have 2 units each with 1 faulty port and 3 units with all 3 ports working.
