It's such a shame that WD discontiued their MyNet range. I have a N750 and it is an awesome router with OpenWrt running. It was far more powerful (SoC + Memory) than any other router I looked at.
I bought it for AUD$50. The closest router in terms of price + power was a TP-Link for around AUD$70 and it still was behind on features.
routers are more expensive and less flexible these days. industry decided that.
what you could get for 50usd (and runs linux, reflashable with your own fw) is now around 200usd and does not support open firmwares like openwrt.
