The HH5 is crap and I am going to change mine for a different router as the new software update for the HH5 has fixed nothing really for a lot of people.
I have mine hard wired to everything and an open reach modem connected to the HH5 so no issues with being disconnected the only thing is the WiFi plays up and disconnects quite a few times a day for maybe a minute or so but not a huge problem as my wife only uses WiFi for her iPhone.
Here is a look at my WiFi log for the HH5 13 fails in about 15 hours.

I have separated both the 2.4 and 5GHZ SSids and also turned off the sync option and selected a channel for both 2.4 and 5ghz and rebooted the hub but nothing makes a difference.
Looking on the BT forum this seems to be an issue as well as the hub disconnecting and no matter what I have tried with other members suggestions the WiFi seems to carry on regardless and disconnect.
My speed is still fine due to having the open reach modem connected to the hub and this is the most important thing to me.
