In April 2016 I bought a RT-AC87U with a 2 yr warranty. In July I sent it out for repair to the west coast ASUS repair center, at my cost!. It was disconnecting from the internet, losing the 5 Ghz signal, losing the internet connection when I would try to upload medium size files and other instability issues. Yeah, I now know those are common 87U issues, wish I knew before buying it but I came from a 56U that worked flawless for years, and still does.
