Summary: I bought this router because I was having problems with the default router provided by my ISP and the two Google Chromecasts I have in my apartment. I researched different options for a while and decided to go with the RT-N56U. It has been working brilliantly since November 2015 (~5 months now).
Excerpt: Bought to replace a similar D-Link router that started giving me problems (unable to resolve DNS names, requiring reset every day or two). Abt price matched a price I found elsewhere and it arrived quickly and well-packed. This was a straightforward plug and play installation.
