DHCP issue Hub 4 - any pointers?

Hello, starting June 28th, my internet connection has been incredibly patchy, both for wired and wireless devices. Numerous ip conflicts are occuring on several PCs , which leads me to suspect the router or upstream are at fault. 

Rebooting the HUB 4 seems to temporaily fix things, and / or resetting the PCs network adapters.

Again this is accross numerous devices, and both wired and wireless. 

Do these graphs look reasonable: 

 

Not sure what my next steps are -report to Virgin Media?  

 

cheers for any pointers, let me know if I can provide any other logs etc

    IP Conflicts are either a DHCP fault and / or a clash of Static IPs.

    IP Conflicts are not related to DNS or to Upstream / Downstream Hub signals.

    thank you for the reply - no static IPs set, which is why I'm confused. Am I correct in thinking DHCP is handled either by or via the hub, so does this mean the hub is faulty? 

    I may of got DNS confused with DHCP... oops

    thanks

    If the VM Hub is in Router mode, then the VM Hub is performing the DHCP function.
    The Hub Connected devices menu page should show a unique IP for each device.

    If you have added another DHCP server (e.g. a Pi-hole ad blocker), the VM Hub DHCP server should be disabled,
    because having two DHCP servers on the same LAN & IP range does cause IP Conflicts.
