Multiple routers on home network

For a very long time I've used old sky routers as AP's on my network. There is 4 of them each on a different floor.
The setup is simple in that the main sky router gives out IP addresses using DHCP
The other sky router AP's are given a fixed IP address and DHCP of all connected devices to these AP's is given the IP via the main modem as the AP's dhcp is disabled. They all have the same password so it allows for auto connect when moving about.
The connection is Router to managed switch via ethernet, switch to all devices and additional AP's
I moved to Virgin recently and kept the same configuration so only the hub 5 is different

I can see the AP's but when connected, there is no internet at the AP.
The hub 5 sees all devices on the network but it does not display the IP address of the AP's
So it can see them and every other device has its IP displayed.
The hub 5 is in router mode

Any suggestions/help to fix this would be appreciated

    Simple error as they always are:

    Checking the managed switch I discovered that it was acting as a dhcp server. Had not made any changes to it so perhaps it was a reboot after a power outage.

    Anyway, resolved..and nothing at all to do with the hub5

    Your routers cannot work because they are on the wrong subnet, so you must change their IP addresses. Do this with one of them. 

    Log into your router and change its IP address to one which is in the same range as that of your hub. If the hub's IP address is 192.168.0.1 and the default DHCP range is 192.168.0.10 to 192.168.0.254 (which I'm almost certain to be true), change the fourth octet (the number in the fourth box) to a different value such as 192.168.0.3 (which must be outside the DHCP range). The subnet mask must be the same as the hub's which is 255.255.255.0.

    You must disable the DHCP server as you do not want the router to do routing functions, that's what the hub continues to do. Turn off NAT and firewall on router if there are settings for these.

    Finally, connect the router to the hub by an Ethernet cable using any of the LAN ports. When you reboot the router you should find that its other LAN ports are active and it broadcasts WiFi.

    If it all works repeat with the other routers but change the fourth octet to 4, 5 and 6.

    Each AP  has a different IP...Its fixed...and dhcp is disabled so only the hub5 is meant to give out the new addresses.
    The AP's are on the same subnet of course.
    In addition, I have reserved the IP address on hub5 as I have done with all devices that sit on the network permanently like switches, cctv, nas etc.

    As I said, nothing changed other than moving to the hub5...so it has to be hub5 related

    The AP's are on the same subnet
    Does this mean the APs are now all on the same subnet as the VM Hub i.e. 192.168.0.xxx   

    It is good to power cycle the Network Switch and all the Sky Router / Access Points.
    This will flush the routing tables of the Network Switch.

    If the Network Switch is a 10/100 or 10/100/1000 Unmanaged Network Switch,
    it must  be connected to one of the Hub 5's three 1 Gbps ports.   

    The 2.5Gbs port of Hub 5 requires the connected device to have EEE Disabled,
    a function that is not possible with an Unmanaged Network Switch.

      yes

      have connected to both gb and 2.5gb ports on the hub 5, makes no difference to the AP's or the NAS/Switch/CCTV ext..as in they work as expected)

      The switch is managed

    Your hub is in router mode so why is your managed switch in DHCP mode? You should have disabled DHCP as you want just one device to be handing out IP addresses - and that should be the hub's DHCP server. Also you should give the switch a static IP address outside the DHCP pool (like 192.168.0.7).
