From: Jan Stary Subject: Re: bwfm fixes To: tech@openbsd.org Date: Mon, 18 Aug 2025 16:22:29 +0200 I have been running this for a few days on a Raspberry 4B (dmesg below) as a bwfm wifi AP for a macbook (running both obsd an macos) and a bunch of androids. I don't see any problems, in fact, the clients seem happier and faster than on the eduroam we have here. What is a good stress test for the bwfm? The topology is {net} - bnx[current/amd64]em - bse[RPI4B]bwfm - [clients].
