A couple of months ago, another setup for a wifi to ethernet bridge was posted here: https://news.ycombinator.com/item?id=26940521

I like Will Haley's setup better though, because it keeps everything in the same subnet.

The slowdown from the bridge is negligible, in my experience. After running 10 trials, I found that:

* median ping was 2.4% higher on the bridged pi

* median download speed was 3.6% slower on the bridged pi

* median upload speed was 0.1% slower on the bridged pi
