My esp has been online for hours but still not showing up. Like I said, one computer with v 1.8.2 shows it just fine but 1.8.7 doesn't. It's good to see that it does work in v 1.8.7 but I'm still confused why mine and the OPs doesn't show up.
What version of Python is running on your computer?ESP8266 OTA Updates with Arduino IDE | Over the Air[ESP8266] Alternative to serial monitor: Wifi Manager + ArduinoOTA + Telnet
I upgraded Arduino IDE on the computer that showed my esp just fine. Now it is as broke as the other computer that is running 1.8.7.
Well, if you want you could reinstall some old version:Previous IDE ReleasesBut I have to tell you that I already had problems with my routers too, one of them was repeater, and this was blocking something, I changed that repeater, and everything became more stable.How is your internal network configured? Do you have many repeaters?
Well I rebooted my router just for fun since that's the first I had heard of there possibly being network issues. Both of my ESP12s show up in the IDE now . Thanks for the tip!
Very well!Please add [Solved] at the beginning of the title
Well it worked for me but I can't speak for the OP.
