That's not simple at all. For the printer I have been moving out old USB printers in favor of new WiFi printers that actually simplify the setup as there are less wires and not as many driver hell issues.
As to a PoE modem router, nice idea but didn't find any today.
Mostly, I've got pretty simple network demands. I need a Docsis 3.0 cable modem (to replace the one Comcast charges me $10/mo for). I need Power over Ethernet (PoE), which is currently supplied by a little Trendnet switch I've got (but I'd like to simplify # of boxes); it powers a Ubiquiti range extender. I'd LOVE to have a USB 2.0 port to run a network printer, and I'd even more love to have a USB 3.0 port to hang network storage on. Oh yeah, and I'd like to serve 802.n and 802.ac network devices.
And, preferably, for less than $300.
