Asus apparently has some problems since the release of new firmware versions is so slow. the last relatively stable version was released almost a year ago, the beta version was released over 4 months ago and there are still some problems with it, by writing this I mean the xt12 model. and all this for close to 1000 euros, here in Europe. I see the same with other router models. Asus! I think it's time to go for quality, not quantity. You produce several models of routers that almost do not differ from each other! invest time and effort in good software, not in more shapes and colors of leds.
