I expected to see the problem somewhere in the kernel, etc. I turned on debugging and kernel tracing and saw nothing. The fix for me is almost identical to the fix that Detlev first described. However, the problem for me was somewhere else entirely. The access point was sending out malformed beacon messages that kept it from showing up. I *hope* that this helps. However, I hope, at least, this was not a waste of bits. :-) Will > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-wireless" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html >
