how is this better than my current solution?

That means I can't use venu lan and have to run my own cables.  Sometimes I
run my own cable, but If I don't have to it is nice to jack into existing
wiring.

"Newer routers, hubs and switches (including some 10/100, and all 1-gigabit
or 10-gigabit devices in practice) use auto MDI-X for 10/100 Mbit
connections to automatically switch to the proper configuration once a
cable is connected."

More hardware and more cables and make sure the right cables go to the
