The connection is lost again - at approximately the same time as yesterday.  
This time I can say for certain that microwave oven activity is not the cause.

Most of the day I have seen a 90% strength connection.  As 8 hours uptime 
approached it suddenly dropped to 14%.  I carried on working, including 
downloading and installing an rpm, for about half an hour.  Then I went for my 
daily half-hour walk.  When I came back the connection was lost and it could 
not connect again.  The symptoms are identical to yesterday.

Using system-config-services I saw that netfs was marked as dead.  That 
suggested to me that it should be running, so I started it.  netplugd is 
marked as disabled but running, as is network.  To be on the safe side I 
restarted both.  I also restarted NetworkManager.  I'd appreciate comments and 
guidance on these and any other services that could be implicated.

I am now going to power down the netbook and leave it until after dinner.  
I'll power it up again in about 1.5 hours.  If it connects then I will suspect 
a component heat problem, although I can feel no heat worth calling from the 
case.
