DNS Issues between Hub 5 router and home alarm system

[bucharest2023]

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.

Panel 30R+ sw 7.03.01
Virgin router
Panel LAN IP: 192.168.0.201
Gateway address (Router) 192.168.0.1
DNS address : 140.192.4.100

Can the DNS be set manually ?

[bucharest2023]

Yes, I did this and manually set to 8.8.8.8

When running a network test the ping fails

[Client62]

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.
