I need a gigabit router which has a download ******* capability even if not connected to a PC. So I have recently been going around the mall and found an Asus Router RT-N18U, a gigabit router, with a download master [built-in *******] capacity...although hindi sya AC at hindi rin dual ban, it is a wireless N600....The box as well as the net says that it has a Cortex A9-800HMz processor and 128MB Flash and 256MB RAM, which features are present in all ASUS AC models.....Since I am not quite familiar with routers, I'm just curious if indeed it would be a good buy at the price of P 4,300.00...

By the way, would flashing a tomato firmware void the warranty? And also, do I really need to flash a tomato firmware? TIA
