@supermach50 you would be better starting your own thread to get replies to your stability problem
this is still an issue to the point our Sky Q box upstairs is no longer connecting to the network even after reboots etc.
The constant drops and/or resets are just st resulting in noise margin increasing and speed dropping
as you have a hh6 have you tried splitting the networks as that might help your sky q box
Sorry I mean rebooting the Sky Q box not the network.
Our router is connected to BT WholeHome therefore the Wi-Fi on the main hub is not used.
