I've had Ultrafast for the last few months and generally the network is very stable and fast. The problems I have experienced ar all due to the instability of the supplied SmartHub.
Every week I have to perform a factory reset on the SmartHub to enable my Cast devices to be discoverable on the network. The Wi-Fi performance is very poor, it does not reach all rooms in my flat.
My own router managed all this fine but because there is no bridge mode on the SmartHub and BT refuse to supply a G.Fast modem, what could be a great service is let down by the SmartHub.
Is there any way around thihs or are we stuck with this poor performance.
you are not forced to use the smart hub. you can use any router/modem on your connection which is approved by openreach and that is your choice and of course at your cost
with the HH6 did you split the wifi networks and then select channels manually? did you try changing wireless mode?
it is not BT Retail that authorise the router/modem but openreach - using google https://uno.help/knowledge-base/article/openreach-approved-vdsl-modems
many devices don't like the networks combined so splitting them often helps your devices with the wireless conenction - you can choose which network to connect to assuming device has 5ghz capability
