That sure looks like the Ubiquiti PowerAP-N, at a little higher price.
I don't know why Ubiquiti is discontinuing production of the PowerAP-N, as it has only been on the market for one year. My unit continues to have excellent range and reliability. I just bought two more PowerAP-N routers (both as spares) from suppliers at Amazon. I would suggest you do the same, before they become impossible to purchase new. As I understand it, the PowerAP-N is still using the same AirRouter operating system with its other routers, so I don't think PowerAP-N users will be "orphaned" for some time.
I just had the top of the line Charter cable router and a new ATT Uverse router installed in my house, as I am upgrading my ISP speed from 6mbps to 15mbps. Neither the Charter nor the ATT router's wireless performance came close to working in my large house, so I have just connected the PowerAP-N with a Cat5 cable to the Charter router.
The PowerAP-N is providing all of my wireless service and has achieved speeds of 25-30mbps down and 3.5mbps up with my new Charter Cable ISP, although typical download speeds (measured by speedtest.net) are 16-22mbps. My operational distances at these speeds are 100-250 feet to several Apple laptops, two network capable LG DVD players and a couple of HP laptop PCs. The wireless signals must go through a number of walls and 2-3 floors in my old Victorian house. The wireless signals to the two HP laptops have to penetrate two exterior frame house walls and travel 100 feet across a tree-filled yard to another outbuilding.
No, I don't work for Ubiquiti, either. I am a mostly retired electronics engineer.
