- Thu Aug 06, 2015 3:53 am #25164 I have a very strange problem. My esp has node mcu firmware. It boots up nicely and gets IP address from the router, but when i see it in my router it doesn't show up. Also when i telnet in to router and give "show ARP ", i don't see any entry for esp. I am able to figure out the IP address from serial. Init.lua contains sample code of httpserver and i can navigate easily.

I don't know what to do. any suggestions ??

- Fri Aug 07, 2015 1:49 pm #25296 There is no mention of the IP or even the MAC address. Also my ESP has the sample web-server code for turning on and of the GPIO pins. I am attaching the snapshot of the arp command of the router. Router is DLINK DIR-600M

Simply do a ping first and then show arp.
