I think 10Mbit ethernet requires 2pairs, 100mbit requires 4 pairs, perhaps
you broke a pair or two during installation.

I used this guide to run reliable 10Mbit Ethernet and an analog phone line
through 8 pair Cat 3 buried under a driveway.

I believe the following may useful and/or interesting:
100BASE-CX (STP) is only spec'd for 25 meters (82 feet). (Same for
1000BASE-CX, 25 meters.)
100BASE-TX uses two pairs UTP, Cat5 or better, 100 meters.
1000BASE-T needs four pairs UTP, also Cat5 or better, 100 meters.
1000BASE-TX uses two

10BASE-T and 100BASE-TX only require 2 pairs. There was a version of
100Mbit that required 4 pairs(100BASE-T4), but I believe it is
obsolete. Anyone still using 100BASE-T4 would almost certainly be
aware of that fact.

Switches don't block broadcast protocols like DHCP. Routers do and if

On a hunch after verifying that it still works when I use a 10Mbit hub,
I replaced the hub with a crossover coupler. That is, I used something
that is almost equivalent to a 100Mbit hub with 2 ports. It isn't
working where I'm seeing the same symptoms.
What could be making this work at 10Mbit

If I were working on this problem, the 1st thing I'd do is use the
ethtool command
to look at the physical Ethernet statistics on both sides. If there's
any problems at the physical layer
you'll see them reflected
