I just bought one of those chinese (apparently the same unit relabeled
and being sold by multiple companies) realtek RTL8187B wifi units. The
price is right.
The label name on this one is WiFySky 1500mW.
other than the fact that the case it is enclosed in is really cheesy,
there is a more immediate problem with this.
the current urtw driver returns a 6.
here we go:

If a verbose boot or any other info is needed to get this working,
please tell me, and I'll get you the info.
I do have to admit, at the price these are going for, they are rather
nice, and do reach out and touch a router. Review complaints: heat
dissipation. If you buy one, don't operate it in a hot environment.
I'd like to see it working in FreeBSD, but I don't have a handle on the
wifi driver structure. Linux source code was included on the driver
disk. I can email that directly to whomever needs it for comparison.
Thanks,
Jim, KC5VDJ
