I did the above.  At first, I set the IP address and I couldn't do the
rest!  So, I reset the router and started again.  I did everything above
and the last step was to set the IP addr of the router to 192.168.2.1 .

After connecting the uplink, the whole LAN still hung.  As before, the
lights on the BEFW11S4 flashed.  Here's the sequence:

1) The Link/Act, Full/Col, and 100 lights on port 1 on the BEFSR41 come
   steadily on, and
2) then immediately afterwards the Link/Act, Full/Col, and 100 lights on
   port 2 on the BEFW11S4 start blinking.

They seem to blink in bursts.  First, the lights on the BEFSR41 come on,
then the lights on the BEFW11S4 blink furiously for 3 seconds and then are
dark for 3 seconds; then, repeating, the lights on the BEFSR41 come on,
the BEFW11S4 lights blink for 3 seconds and are dark for 3 seconds.  This
cycle repeats over and over.

During this time, the LAN is unusable and only a few packets (if that)
manage to get from one computer to another.
