I got this one from amazon on a sale, the things that I like about this router is its speed. if u have a big home say 1300 sqft, this will not work, as you can experience signal loss.
The router has three modes
AP-Access Point
Repeater-
Wifi
I tried to update the router once and it stopped working, but asus replaced it with an other one, I tried using this router as a repeater but it never works.
Apart from that if u have a small house and need a decent router within your budget you can buy this.
