UDP over MQTT Loosing Packets?

Looking for advice, I`ve been trying an app using MQTT over wifi. I have a strong wifi signal at 600+m, but I`m losing connection to the MQTT Broker at about 150m?
I`m sending about 10KB on data at a time, and the Broker is responding back with about 2KB of data. I`m unable to reconnect without resetting the MQTT Broker, any suggestions as to what's happening?
