Good.  Mine is apparently somehow aberrant.  So the question now is 
hardware or software.

I'm voting for software.  I see ke-recv occupying >50% of cpu and >25%

And everything I try to do is terribly slow.  Even after what I think of 
as a "reboot", though I'm not sure which options *really* are equivalent 
to what.

Software is a good answer, in that I can conceivably fix this myself 
somehow.  Someday.

When I'm at work, I'm not connected to Wif.
