DNS Issues between Hub 5 router and home alarm system

My Home alarm panel is connected to the router via ethernet.

The DNS address given out by the router ( DNS address : 140.192.4.100) is a strange one and not a normal “Virgin” DNS address.

The control panel network test is a routing ping test to google 8.8.8.8 address...the ping fails and the alarm system can;t connect to the cloud.

This issue only arose after a power cut - no router settings have been changed and the alarm system was fine before.

Any assistance would be appreciated

    That is a odd IP for DNS and you say your in router mode?

    Do you have HomePlug - Network Via Mains?

    What are the IP details of the panel?  They should be 192.168.0.xxx and Gateway 192.168.0.1

    140.192.4.100 is not valid and is as if the Hub 5's DHCP server has handed back an invalid response.

    If possible, check the Gateway & IP of the alarm panel. 

    With a VM Hub in router mode the Gateway has to be 192.168.0.1 ( any other value would fail the ping to 8.8.8.8 ),
    the alarms allocated IP should also be in the range 192.168.0.xxx

    If a manual configuration of the alarm is possible one could try :

    IP Address 192.168.0.200
    Mask   255.255.255.0
    Gateway 192.168.0.1
    DNS:  8.8.8.8  and  8.8.4.4

    That IP address is a University in Chicago.

      Yes, I did this and manually set to 8.8.8.8

      When running a network test the ping fails

    From your LAN is it possible to ping the alarm panel at 192.168.0.201  ?

    Encountering DNS issues between a Hub 5 router and a home alarm system can disrupt connectivity and remote monitoring. Cox internet providers Troubleshoot by ensuring the router's DNS settings are correctly configured and compatible with the alarm system. Verify network connectivity and consider assigning static IP addresses to the alarm system components. If problems persist, consult the router and alarm system documentation or contact technical support for assistance.

    Make sure you have the correct gateway 192.168.0.1 and the correct sub-net mask 255.255.255.0 in the unit.

    Does the alarm panel have a static IP address?  Is this address outside the DHCP scope?

    Just thinking about the power cut.  The alarm IP may have been fine before the outage, but the Hub's DHCP may be clashing after this outage?  Just something to check.

      The panel is set to DHCP but can also allow to switch to manually update. The panel IP Address is failing a ping test from my laptop
