Netgear Prosafe Bonding Router Recognising only 1 of 2 hubs

We have two isps (Virgin and BT) and both hubs have been tested independently and work as advertised.

However, the point of having two isps is that, in the event of one going down, we still have a service.

Hence they are both connected to a Netgear ProSafe Bonding Router. (which, when it's working properly also bonds the services and allows us to approximately double our broadband speed in certain use cases)

My problem is that the router recognises the Virgin Hub, no problem. But does not recognise the BT Hub and this the admin screen is telling me that WAN 2 (the BT hub) is down, when it isn't.

I thought I'd cracked it when I realised that the default ip address of the BT hub was 192.168.1.254 which was already occupied by a Novell Server. So I changed the hub address to .200. Forced the router to refresh its search for hubs.  Nada.

Any ideas?

What Netgear device is it that you're using? Is it handling the authentication to BT's network?

It sounds as if you are trying to use the same subnet on the inside and outside of the netgear router, renumber one of them to be on a different subnet

Is the BT connection ADSL or vDSL?

apologies for delayed response. Been away.

And no.   Nor does it handle the Virgin auth.

>>It sounds as if you are trying to use the same subnet on the inside and outside of the netgear router, renumber one of them to be on a different subnet

not sure I understand that.  I log in to the netgear router using ip 192.168.1.1 and the BT router is now 192.168.1.200 (after I spotted the conflict above). Are you saying I should change the BT router to, (eg) 192.168.2.200? (I suggest that because the Virgin router is on the 192.168.0 subnet and I'm presuming that we don't want to be on the same subnet as that either)

>Is the BT connection ADSL or vDSL?

...is a question I've never addressed. However they're both 100mb/sec services so I'm guessing they're both vDSL

The Virgin connection uses DOCSIS 3.0 if I remember correctly, not any form of xDSL. If you have a BT hub then that connection is vDSL.
Have you tried configuring the BT device as a bridge and letting the FVS336G handle the authentication?

>Have you tried configuring the BT device as a bridge and letting the FVS336G handle the authentication?

not yet. My gut says Arnelovius observation about subnets is the next thing I need to try. This is because the netgear isn't even recognising the existence of the BT router - so configuring to login to a service on a device it doesn't recognise sounds a bit unlikely. However, if I get the netgear to recognise the BT router and STILL have no BT access, that'll be the time to try the bridge route.

Not only does it not make any difference which goes into which port, but I've even tried the BT router on a spare bonding router (older model we replaced).

Got the IP changed to to 192.168.2.254 on Friday. Then discovered that, despite showing itself as connected and with an external IP address, we had no real connect to the web. BT tried to diagnose it remotely and reported an "unknown fault", so they have an engineer coming out tomorrow to attend. I'm guessing he'll probably replace the router and it wouldn't surprise me if the other problem then disappears entirely.

Closing this in the absence of solution but Perarduaastra's input has been helpful

You don't say which BT hub you're using, but if it's an older one that requires the white ECI or Huawei modem to present the internet connection to the router (BT Hub) via Ethernet then try using a crossover cable to connect the modem to the BT hub. Make sure that the BT hub is in bridge mode so that the Netgear device still handles the authentication for the connection.
I remember tearing my hair out some years ago over a similar problem involving a different router, and using a crossover cable fixed it. Apparently the Ethernet port on these white modems isn't auto-sensing...
