I found the problem and fixed it.   

I was running my router wide open.  I don't mind sharing my connection. 

The essid on my router was "linksys".  It turns out that a neighbor
recently moved in who also set up a linksys router... with an essid of
"linksys" as well.  It also turned out that his router was within range
of my linux laptop.

Thus I was connecting to his router half the time !

I changed the essid on my router and reconnected.  Everything works
perfectly. 

LG
