OK, so what does the new service connect to? There must be some ISP box to
convert fiber to ethernet.
What all is hooked to the ISP's box? Does this ISP box have an interface of
some sort to check it's status?

> Router is an ASUS RTN12D1 running a variant of dd-wrt 3.0.0.4.380_8120 at
lan ip 192.168.1.9 .
Which side of the router is 192.128.1.9? The LAN port? What address is on
the WAN port?
What all hooks to the LAN port(s) on the router? What other networking
devices are on your LAN?

BTW, is an 'm/c' a machine? Naming devices what they are would help
describing your environment.

Are you sure it's DNS issues? How do you know?

What sort of "main box" do you have? It is unlikely you have to reboot it
because of network issues.
There are commands to drop and restart networking on Linux and for Windows,
if you are using DHCP, you can
also /release and /renew your address.

> Have an i5 m/c with OPNsense installed. Its telling me that its lan ip is
192.168.1.208.
This is separate from your main box? What do you have OPNsense configured
to do?
How many interfaces? Can you hook up a monitor and keyboard and configure
it locally
verses over the network?

Same question; Can you hook up a monitor and keyboard and configure it
locally verses over the network?

m/c is her phone in this case? It's connected to the router on WiFi?

> My cell phone is connected to the network and has web access.
Over WiFI or via the cell network?

> (Can see the m/c on the router - its ip address is 192.168.1.30. Can ping

Again, m/c is your cell phone? We have iPhones, and they can't be pinged or
pretty much anything on the lan.

That doesn't make sense. In your entire network using WiFi? If so, you
might have better luck running some
ethernet cables for a while until things are stable.

What is a "router class m/c"? What are they doing (if you don't mind
saying)?

> Is the asus router getting flakey?
Maybe, but you aren't providing any data to make that determination.

Try that again. It's really hard to work on network issues over a broken
network, so try the next easier things first.
