Are you sure MIPS is only used in crap routers? For example https://www.ubnt.com/edgemax/edgerouter-lite/ this is MIPS as documented for example https://wiki.gentoo.org/wiki/MIPS/ERLite-3 here. Also, one of the first 802.11ac Wave 2 routers from Xirrus, that's also MIPS, isn't it? http://www.wireless-mag.com/News/34108/xirrus-selects-cavium...
