I checked the Linksys web page for a tech support number, and it said
24/7 tech support, so I called.  I got a sweet sounding lady with a
thick Chineese accent.  She was obviously trying to fit me into one
of her pre-scripted categories, as she insisted on determining whether 
I was using the hub for "file sharing" or "connecting to the
internet", and she also wanted to know the name of my ISP!  I asked to 
speak with someone a bit more technical.  She asked me to please hold.

After 15 minutes of hold (God bless speaker phones!) she comes back
and asks a few more questions trying to show me how "network
congestion" is causing the packet loss.  Good Grief!  My kingdom for
an engineer!

I think Linksys headquarters is going to receive a call from me
tomorow morning.
