I have the same machine, same wifi card, and definitely similar
issues. I'm kind of relieved to know I'm not the only one. I've
tried multiple access points, forced 11g mode, 5GHz band, but the
issue persists. I get poor speeds and stalls -- some web pages never
finish loading. I've also tested with iperf on my LAN and have poor
results there as well. In a live Antergos Linux environment, I
achieve the full potential speed.
This issue has been ongoing for me since I installed OpenBSD 6.1 on
this machine, and I'm now running a snapshot from April 22. Until
pretty recently, I've only used this machine casually, so aside from a
little frustration, it hasn't affected me much. I would love to be
able to get this resolved though.
My dmesg is below. Please let me know what other information I can
provide or troubleshooting steps I can take.
