So ... thanks to Rathbert and Alex (Visionworks) we seem to be (so far, touch wood) back and running...

I went Occam's Razor and back to minimum setup then bit by bit re-built. A few things along the way...

1. 861 and MS200 needed firmware updates.

2. When putting the D-Link switch back in (yes the Green Ethernet one) I ended up putting the DIM switch back to "Flow Control = ON". I know there is endless debate about Green Ethernet not playing nicely and about a 50/50 split on Flow Control On or Off debates but for the moment it's ON and it's working!

3. Devolo MAGIC 2 all now plugged back in and working. Internet through the house (albeit with bad areas due to bad wiring) but all flowing and nothing (touch wood) dropping out.

Now been operational 15 hours + per day since last Friday and so far (fingers and toes crossed) all working.

Also, the continuous need to reboot and then rebuild the QNAP has also stopped (Check File System not Clean) so weirdly that's all sorted as well.

And now what's most exciting is that my 818v3 and DSW will be finally arriving in Kenya NEXT WEEK!!! Only a year and 3 months after I bought them!!! So then we can do all DSP firmware updates and get the 818 into the 8k's moving the MS200 into the AD88 upstairs smile
