I have a device that I programmed with a static IP 192.168.5.?.  Yesterday I replaced the router.  The new routers IP is 192.168.6.1.  When I look at the connected devices I don't see my device I'm assuming that's because I was using IP'S 192.168.5.xx range now it's 192.168.6.xx range.
How do I connect to that device when I can't remember the static IP

connect device to the network, connect your pc to the same network, use like a /16 network mask on you pc, say 192.168.5/255.255.0.0, ping the broadcast address. ping 192.168.255.255, then check the arp table on your computer, ie. show arp.  your device should respond to the broadcast ping and populate the IP/MAC to your computer in the arp cache,  then you should have the IP.

Another thought would be to change the router to use the 192.168.5.x range
Take a baseball bat and trash all the routers, shout out "IT'S A NETWORK PROBLEM NOW, SUCKERS!" and then peel out of the parking lot in your Ferrari.

OP sometimes you can configure a 2nd address on the same network to allow you to connect to the downstream device and change it's IP. Then remove the 2nd address once you're done.
