N450 CG300DV2 wifi can be found be devices, but no connection

Mediacom internet customer; my internet went out today, I called and they didn't have an open ticket on it, but took the info.  About 2 hours later I tried cycling the power/disconnect cables and I got my blue lights showing inccoming and outgoing connections.  However, even though I can connect to the internet through the modem/router via wired-LAN (as I am right now on my laptop) my wifi will not make any connections.  Devices such as smartphone and Roku can 'see' the network and attempt to connect - my phone gets a 'failed to obtain IP address' message.

Also, I cannot make a LAN connection to the modem using 192.168.0.1  and I guarantee I did not reassign the address of the modem.

BTW, I read entries that talked about firmware pushes; as I own this modem, can the ISP still push fimrware upgrades to it?  If I could get inside the modem I could probably find that answer....

       Actual error message?

       With the working wired connection, what is the IP address of the
    connected device, and what is it using as a gateway/router address?

       Does a command like "ping 192.168.0.1" do any better than using a web
    browser?  (It's not unheard of for a web server on a Netgear router to
    die (more or less) spontaneously.)

       One more thing to try for a cable modem(+router) would be
    "192.168.100.1".

       I gather so.  These forums contain many complaints about ISPs which
    won't push firmware to user-owned equipment, and about as many replies
    from Netgear people who say that only an ISP can (and should) do it.
