I just bought a Dlink DWL-520 PCI adapter. I also upgraded to 4.9 STABLE and
even made the world. FreeBSD was able to detect the wi0 card but I am having
issues with it. Below is the error message I got in dmesg.
wi0: <Intersil Prism2.5> mem 0xfedfd000-0xfedfdfff irq 12 at device 14.0 on
wi0: couldn't reset prism2.5 core.
device_probe_and_attach: wi0 attach returned 6
