I've got a BT HH3. According to BT, http://bt.custhelp.com/app/answers/detail/a_id/32322... ports 1 to 3 are equal and 4 is a Gig-E Port.
I've recently had a Salus IT500 internet thermostat fitted to control the HW and CH. It has been locking up. The Iphone App says the IT500 is offline, but the IT500 gateway and the IT500 control unit both show that they are on line. The only way to restore the connection is to reboot (take out battery) the IT500 contol unit.
I'd connected the IT500 gateway not to the back of the HH3 but via a Devolo 500 Home Plug.
Salus are saying that they have never tried it using Home Plug and their website http://www.salus-tech.com/faq/it500-faqs/ gives advice such as;
Q. I have a new BT Hub 5 router and the gateway has a solid red light.
A. BT Hub 5 uses ports 3 and 4
I have spoken to their Tech people and they say that on a HH3 Port 3 should be used. I'm trying this at the moment - and the lock out usually takes 48 hours to occur. I cannot see any logic / reason for using Port3. None of my other devices specify which port should be used to connect to the router and apart from Port 4 (Gig-E) all the ports seem to be equal. My view is the addition of a Home Plug shouldn't be a problem either.
Any thoughts from anyone?
