Hi Joseph,
First to give you an idea what LEDE is, I would recommend (if you didn't already do) to read the start page of the LEDE Project: https://lede-project.org/
LEDE is a custom firmware available for many routers. It requires a little bit more knowledge to get what you want from it, but it's very powerful because you are in control. It's also very expandable. And secure. I'm not going to resume the main LEDE page here... 
If you feel uncomfortable about having the LEDE firmware, you can always reinstall the stock TP-Link firmware. There is a video on Youtube about that, and you can read more on the subject here:
Just make sure to understand everything that has to be done before attempting the restore and feel free to ask questions. Do not rush into the process.
Point worth noting: You need to use a stripped firmware from FriedZombie's website to restore, after you can use the standard stock firmware as usual.
