Sonicwall TZ210 Access

Not sure what happened when we installed the new firmware to a TZ210   (end of life soon,)  and I have never had to access the router directly.
Can someone give me very easy steps to follow so I can plug my laptop into the device to see why I can no longer ping or communicate with it.
This is a very small secondary network.   3 devices for creating VPN tunnels to branches.   Updated firmware on branches first and then this one.   Now we can't use web interface or can't ping it.    So I am trying to plug in my laptop.

Ethernet port on laptop and then connect WHERE?

The router has WAN and LAN interface cables  with a DSL modem attached.   I tried the LAN port and nothing.   Won't open web page to log in

Sorry, but I am really GREEN.
