Great performance, questionable long-term,
This review is from: TP-LINK TL-PA211 200Mbps AV Powerline Adapter (Accessory)
I bought three of the TL-PA211 in Aug 2012.
First up, the networking speeds I got were fine, even for streaming video. I have no problem with the product other than its durability.
The first one died after about 12 months, but I put this down to moving it to a location with poor ventilation and it overheating. As I'd run an ethernet cable to my office (by far the most reliable networking option) I only needed two so wrote off the broken one.
I've now had another one die, so that one lasted 18m, and it was well ventilated. The dead adapter humms quietly when plugged in, so power is getting to some of the circuit, but it's unresponsive and none of the lights come on. I'm guessing something has burnt out in the AC-DC transform.
I can see that TP-LINK now have some "nano" versions of this product for around £14 a pair. Given the cost to replace the failed units I won't complain to much, but I would expect them to last more than 18 months.
