Ethernet PCs Not Seen On Home Network

[my-generation]

In connection with this problem I ran the network diagnostics tool on my hub 3.0

It came back with "gateway ipv4 address is invalid"

How do I fix this please?

Is that a complaint about the Gateway address of the VM Hub 3 or the PCs ?

For a Hub in Router mode, the PCs etc should use Gateway address 192.168.0.1 ( the IP of the Hub )
For our Hub 3 the WAN Gateway is [REMOVED]  & is seen at Hub 3 menu >>> Admin >>> Info

Looking at the Hub 3 >>> Connected devices, static IP devices and Reserved addresses below the DHCP range are not listed.  All of our devices with  regular DHCP IP from the Hub 3 are present in the Connected devices list.

It's simply a question asking how can I fix a  "gateway ipv4 address is invalid" message which the hub tells me following using the network diagnostic tool

Do you have a broadband problem.

No, but I have since found that uninstalling the ethernet network adaptor when shutting down ensures that it works when next boot up. Strange.
