Ok, so your using a free wifi hotspot for gaming.....and you cant understand why your connection is obviously being throttled based on the number of packets and bandwidth your taking up???
There is nothing to configure on a "free public" hotspot unless your gking to go call Comcast, and tell thm you need your connected IP port forwarded and unthrottled.....to which they will tell you to go fuck yourself.
Using a free wifi hotspot or anything mobile is worse than a basic Colombian wired connection.
