Nighthawk CAX80 not issuing new IPs

I have had the Nighthawk CAX80 for just one year and had several issues with this router. This time I happened to be traveling and working remotely. The issue is  that the router is not issuing new IP addresses. I have several machines and an esxi host, when i create a new VM nothing works, no new IP whastover. I thought the issue was the DHCP, but when I check it says everything is working properly. Is there anything i can do to make this work? To get the DHCP to issue IPs? I rebooted several time times and so far nothing is working.

do you have issues for devices that aren't VM's?

The devices that are not VMs have had the same IP for the last few months until i changed the Subnet. But even when I reboot the router the non VM devices maintain their IPs. But these IPs are not static.

Basically I'm curious if you connect a new (non-VM) device to the router,is it assigned an IP address? 

What are you setting with static ip addresses? 

Any other devices on your network acting as a DHCP server? (managed switch, access point that might not be in access point mode)

   A vague description of what does _not_ happen is less useful than a
clear description of what _does_ happen.

 

   The non-psychics in your audience might know very little about the
network configuration of these virtual machines.  If a broadcast DHCP
request does not propagate from a VM to the CAX80 (with its DHCP
server), then I wouldn't expect it to respond.

  "check it"?  "check" _what_?  "check it" _how_?

 

   None of that is a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

   Huh?  "not static"?  I don't know what that means.

 

   Terminology: A "static" address is configured on the device itself.
What you configure on a (DHCP server on a) router is a reserved dynamic
address, not a static address.  Either one should fix the address of a
device, but some implications are different.

   _That_ would be a useful test of the CAX80 DHCP server.
