I actually DO have a bridge from my router with a wired connection to my RPi 3+. It is relatively simple and works great with no slowness at all.
I use a dLink WET610N Bridge/Access Point in Bridge Mode which feeds from my Linksys 1200AC router through 2 wall to the livingroom. I have the RPi 3+, TV and NAS all connected to it with no problems. You will not get more than wireless AC speeds but I haven’t had a problem with any of the current video formats However, I haven’t tried any 4K files yet.
