I have an ESP8266 (NodeMCU v1) connected to my home Wifi, but i'm having troubles connecting it to any LAN device, in fact the connections simply fails :/
But it does not fails everytime, sometime it works when I change the ESP's static IP, but when I restart it, it stops connecting... weird.
It does works very well with an old Netgear router, but not with my ISP's router (Orange).
I don't know if it's really related to the ESP itself but I think so because others LAN devices has not difficulty to communicate with each other.
I'm using the latest Arduino IDE for ESP8266 (with the latest SDK I guess?) and a sample code (connect to a web server then do a GET request).
Any help would be appreciated
