For comparison, I have a MQTT Gateway running on a Wemos D1 for 2 months now, with a RFM69W. Works perfect. Here is my hardware setup and code, maybe it is of any help to you. Change the networkid, MQTT broker and wifi credentials to your own setup. I use static ID's on my nodes.
// Enable debug prints to serial monitor
#define MY_DEBUG
// Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
#define MY_BAUD_RATE 9600
// Enables and select radio type (if attached)
#define MY_RADIO_RFM69
//#define MY_IS_RFM69HW
#define MY_RFM69_NETWORKID 83 // Own network ID, mysensors default is 100
#define MY_GATEWAY_MQTT_CLIENT
#define MY_GATEWAY_ESP8266
// Set this node's subscribe and publish topic prefix
#define MY_MQTT_PUBLISH_TOPIC_PREFIX "mygateway1-out"
#define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "mygateway1-in"
// Set MQTT client id
#define MY_MQTT_CLIENT_ID "mysensors-1"
// Enable these if your MQTT broker requires username/password
//#define MY_MQTT_USER "username"
//#define MY_MQTT_PASSWORD "password"
// Set WIFI SSID and password
#define MY_WIFI_SSID "xxxxxxx"
#define MY_WIFI_PASSWORD "xxxxxxxx"
// Set the hostname for the WiFi Client. This is the hostname
// passed to the DHCP server if not static.
#define MY_HOSTNAME "ESP8266_MQTT_GW"
// Enable MY_IP_ADDRESS here if you want a static ip address (no DHCP)
//#define MY_IP_ADDRESS 192,168,178,87
// If using static ip you can define Gateway and Subnet address as well
//#define MY_IP_GATEWAY_ADDRESS 192,168,178,1
//#define MY_IP_SUBNET_ADDRESS 255,255,255,0
// MQTT broker ip address.
#define MY_CONTROLLER_IP_ADDRESS 10, 0, 0, 47
//MQTT broker if using URL instead of ip address.
// #define MY_CONTROLLER_URL_ADDRESS "test.mosquitto.org"
// The MQTT broker port to to open
#define MY_PORT 1883
// Enable inclusion mode
//#define MY_INCLUSION_MODE_FEATURE
// Enable Inclusion mode button on gateway
//#define MY_INCLUSION_BUTTON_FEATURE
