@David-TP Here is the network Plan from home.

I just realised that when the Internet is Down the wired network stops working. The wifi keeps working and I can see other computers on the network but all wired computers no longer get DHCP...

Just installed the deco M5 everywhere and now the Kindle (voyage) can not see the network. Based on my readin gthe Kindle is limited to channel 1-11. Anybody found a work around since the Deco M5...
