We review the hip and new ASUS RT-AX88U, this premium router is compatible with the new AX standard also labeled as WIFI 6 standard whilst retaining it's compatibility with AC and lower bands as well. The AX88U seems to be a bit of a beast alright, loaded with features it should offer really good wired and wireless performance. The triple band Wi-Fi router from ASUS has been fitted with a quad-core processor even.
