At Omni we're using TP-Link dual-band home routers (N750) and modifying them for PoE.

These routers have gigabit ethernet.

Unfortunately gigabit ethernet and PoE at the same requires special ethernet transformers and these routers don't have that type of transformer.

This means that they drop to 100 mbit when we modify them for PoE (but only on the port we modify).

I was looking into how to get around this problem.

I thought maybe there was a way to do gigabit half-duplex on two or three pairs, but it seems like that's not possible.

BUT! It looks like TP-Link makes a PoE splitter which can apparently handle gigabit:

  The TL-POE10R

Here it is for $12:

I ordered one so we can try it out. If it works we should just do that to all of the routers. No reason not to have gigabit if it's only $12 extra per router. It's still only $77 total for router + PoE splitter.
