Connect FTTC Modem to Router via Homeplugs?

[Virdi]

Hi all,

So I finally had my Plusnet Fibre installed yesterday.

The BT Master Socket is in the back bedroom and this is connected to the BT Openreach Modem.

I then have the 'LAN 1' port connected to a homeplug.

The second homeplug (in another bedroom) is connected to my Billion Router (EWAN port) - and the setup is working.

However - I need to have other Homeplug(s) on the LAN side.

So effectively, this is like having two networks over the mains wiring (via homeplugs)

...is it 'ok' to do this?

Thanks
