With my x201s direct attached to the Monkeybrains PoE box, I get 10 MBit
down and 20 MBit up -- saturating the downlink on my other end actually.

Going to a faster target I can push 30 MBit up the monkeybrains link.

Weather's clear right now, so no rain fade.  Would be good to watch
throughput as the air fills up with H2O.

The problems we're seeing with the switch+router in the picture could be
due to Cisco 100baseT negotiation problems perhaps?  Or a bad patch cord
I guess.  I'm likely to break things if I try configuring vlans or
forcing port speeds so I'll leave that to y'all.

I've put the cables back the way I found them.
