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

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.
