I've currently got a BT Home Hub 6 on a FTTC connection and I've read some comments there can be issues with this kind of setup.

What I would like to know is will it work with the HH or does it replace the HH entirely?

If it works connected to the HH are there any features that I lose having it configured this way?

Are they easy to configure?

Thanks in advance for any advice.
