Broadband (Fibre)

I had the same set up as you but with an Airport Extreme instead as a Time Capsule and have moved to BT Infinity or at least I will when they get around to switching it on.

Unfortunately the HH5 cannot be set to Modem only so even if you switch the WiFi off it will still operate as an up stream router which will give some issues with the Time Capsule . To get around this you need to either do what you have suggested in getting a Vigor 130 and ditch the HH5 or ditch the Time Capsule and use the HH5 which I wouldn't personally recommend but if you do make sure you have a switch for your music.

The other alternative is to use the Time Capsule in Bridge Mode with the HH5 operating as the primary upstream Router. This is fairly simple using Airport Utility but if you get an issue post again and I will run you through it. I have done this and will see how it goes but will go the 130 route if dissatisfied.

What issues with TC please?

Very briefly, TC uses PPPoE which HH5 does not support.

I have  BT HH5 and an Apple TC which just does back ups and seems fine.

I have no idea what PPPoE is?

Is there any other set up that TC doesn't like?

If its just being used for back up, I assume (given that a TC is only an Airport Extreme with a back up facility) it's fine. I am talking about using it as a Router.

Use the HomeHub as a router.  Connect one Ethernet patch cable from it to an unmanaged switch.  Connect everything else to the switch, including the TC.

Set the TC to be in bridge mode, and to 'create a wifi network.'  Turn off wifi on the Home Hub.

That's my recommendation; it's what I do at home, but with a different ISP and a different piece of hardware for the 'home hub.'

FYI for all TC users:  I was having awful network issues with music dropouts on my NDS and Qute2.  The music would start playing but randomly pause and restart, or drop all together.  I pulled things off my network one by one and learned it was the TC screwing something up.  A did a factory reset on the TC and it's been fine ever since.  I have no idea what was going on . . . but the TC was a problem and after a factory reset and reinstall just as it was before on the network, all is well.  Something must have gotten corrupted.

OK thanks.

No. I said it cannot be set up as a Modem only which isn't quite the same thing. You can switch the wifi off but it will still act as a Router through the Ethernet connection and that is the compatibility issue with the Time Capsule.

if it helps draytek supply a modem router that can switch between ADSL/VDSL seemlessly provided you enter the tag "101" in the VDSL config on the router.  I have one and it worked perfectly on switchover.  It is the DV 2860

Ok ...let's see ...

What about BT Homehub 5 (combined fibre modem and router) with wifi switched off. All Ethernet connections to the BT device (perhaps using a Netgear switch) and also the Apple Time Capsule connected via Ethernet (in bridge mode) - used for the all wifi functions.

Does that sound reasonable or have I completely lost the plot  ?

(obviously difficult to properly consider options until the fibre and kit are installed - so just trying to plan ahead, pending installation in 2 weeks )

Spot on! That's what I would do with BT Infinity.

PS don't get hung up if the switch is consumer grade 'managed' - some of the new devices are still very simplified but you have options for setting QoS and handling multicast which can be useful as you start to get more and more applications and users using your LAN.

That sound right to me - it's the same as what Bart suggested above, isn't it?
