I'm using a Huzzah ESP8266 and my code fires up the ESP8266 Access Point so I can connect to it via TCP to send Wifi credentials over. When I set the default IP with softAPConfig, the HTTP Client fails to work. This only happens on certain routers and it fails on the current router it's trying to connect to which has an IP range of 192.168.1.100 to .199 The default gateway is 192.168.1.254.
When I set the softAPConfig IP to 192.168.1.1, the HTTP client fails to connect. If I set it to anything else; i.e. 192.168.0.1, the HTTP client works fine. Here is the test code to recreate the problem:
