None built in from what I recall. That was from back in 2011, so it’s possible things changed since.
Reading through, it looks like retries do exist, but remember that duplicate packets are treated as a window reset, so it’s possible that transmission succeeded but the ack was lost.
I remember the project demos from the course though - one team implemented some form of fast retry on two laptops and had one guy walk out and away. With regular wifi he didn’t even make it to the end of the hall before the video dropped out. With their custom stack he made it out of the building before it went.
I’ll need to dig through to find the name of what they did.
