Hi.,
You may find this to solve:
On the BT HH6:
x.y.z.= your network address i.e 192.168.1.?
Fixed/Reserved IP address setup :
Advanced -> Home Network -> DHCP Table
Choose device in question -> enter chosen IP address and tick 'always use this IP address', apply.
choose IP address outwith DHCP range (see below) so it's easier to identify, e.g.x.y.z.50 to x.y.z.99
Advanced ->Home Network -> IP Addresses
DHCP Network Range
tick 'Configure Manually'
start =x.y.z.100
end =x.y.z.200
apply
Makes it easier to identify how any device in question was assigned it's IP address.
i.e. IP address of x.y.z.101 = DHCP assigned IP address
