I was trying to upload this sketch to ESP8266 and it was never succeeding connecting to my Wifi.

I replaced the connection string to hardcoded WiFi.begin("mySID", "myPassword") and it connected allright.

The problem is probably, that you read the input until '\n', which in Windows is preceded by 0xD0 character, which is not visible, but is perfectly translated by
input.toCharArray(settings.password, BUFFER_SIZE);
so I put after this line following line of code (after both ssid input and password input lines 92, 99):
if (settings.ssid[input_len-1] == 0x0D) settings.ssid[input_len-1] = 0;
if (settings.password[input_len-1] == 0x0D) settings.password[input_len-1] = 0;
respectively.
Of coarse you have to preceed the line 91 by
int input_len;
and change both lines 91 and 98 to:
if(input_len = input.length()) {
[it is really = and not == here]

and now it connects!
