problems connecting BEFSR41 with BEFW11S4

[http://dummy.us.eu.org/robert (Robert)]

Hi.  I have a BEFSR41 and a BEFW11S4.  I already had the BEFW11S4
and it works great.  I bought a BEFSR41 hoping to connect them together.

Before doing anything, I changed the IP address for the BEFSR41 to
192.168.1.5 .  (The IP address of the BEFW11S4 is 192.168.1.1 .)  I also
disabled DHCP.

When I try to connect the uplink from one router to another, it doesn't
work.  I tried:

1)	BEFSR41 uplink -> BEFW11S4 port 2
2)	BEFW11S4 uplink -> BEFSR41 port 2

Nothing is plugged into port 1 nor port 4 on either router.  I am using
a standard CAT5 ethernet cable.

When I try either #1 or #2, the network gets flooded with ethernet frame
packets.  (I tried tcpdump when I connect them together, but there are no
TCP/IP packets.  So, I assume that they are frames, not packets.)  When
trying #1 or #2, I am unable to connect or send any data over the LAN at
all.

I also tried clicking on the "router" button (instead of "gateway") on the
Dynamic Routing tab on BEFSR41.  It made no difference whatsoever.

I tried unplugging both of their power supplies and plugging them back in.
It made no difference.

I speculate that the switch is trying to "learn" the MAC address for the
port since the 100Mbps light lights up temporarily before flooding with
the frame packets.  (All of my ethernet cards are 10Mbps, not 100Mbps.)

The firmware level on my BEFW11S4 is 1.37.9b, Jun 21 2001.

The firmware level on my BEFSR41 is 1.42.3, Jan 28 2002.

Thanks.
