Ok here goes, this can get complicated if you think about it the wrong way.
To start with configure node A to use the preferred gateway at node D, you will find this on the WiaNa settings. This will ensure that all traffic on node A uses Node D for its Internet traffic.
Then set, in WiaNa again, the 2nd preferred gateway to node B. Next you need to set the following, again in wiana 
Disabled failed upstream, which is in the extra features menu
Then in Custom local test host: you need to put an ip address in one that is part of your isp but before the internet. For example do a Tracert in cmd promt for www.bbc.co.uk then you will see a list of ipaddresses. I use tiscali, so …. I picked an ip address that was still part of the tiscali network, there for it must be a RouTer or a firewall, or something else belonging to tiscali. Input this number into the field.
Then if your ISP fails or your connection to it fails the MeshAP will not be able to ping it and turn itself into a RepeaTer. So in your scenario node A is using node D for its internet traffic. Node D is checking that it can see your ISP router, the ISP router goes down or there is a lockup on your local router. Node D can not see the ip address any more so it changes to a RepeaterNode.
Node A then sees that node D is no longer a GateWayNotes and decides to go to its 2nd preferred gateway and once again internet is re-established. Be ware though – the node D will not revert back into a gateway unless it is rebooted and can pick up an ip address!

I have 5 nodes, A, B, C, D and E. I have 2 backhaul routes. One is ADSL the other is SateLlite. Node B is one hub with ADSL connected and D is the other with Satellite. I want all users traffic on A to go through the satellite which is on D. A can only see D "through" B. Will the traffic be routed correctly or will it take the shortest route i.e. using B's ADSL backhaul? Of course if the satellite should go down, I want the traffic to go through B's ADSL backhaul route.
