As you suggested earlier, a slow clock setting in the bcm43xx device may be the cause of this
difficulty. If my laptop would suspend/resume correctly, then I could test various fixes based on
that hypothesis. Since it does not, I think the band-aid approach is warranted. A proper fix is
still on my agenda; however, getting full data rates still has priority.
