Absolutely not. CIte, fucktard!
There is ONE set of units by a company (Linksys) that was subsequently bought by Cisco that operated using an OS (Linux) who's license requisites required that they release the source code of their OS. The rest is history. Those units now have several flavors of Linux based "OS" variants that run on them, allowing them to operate like the pro models from back then do.
Nothing since has had it from any brand, because they would ALL have to release the source of their OS and routing schema, and none of them want to do that, so NO, it is NOT Linux on them (or we would be seeing OS discs with them). Just that one little family of Linksys (Cisco) products. And a few other makers they licensed it (the base design) out to. That's all. So from about 6 years ago on... nothing. I can cite that.
Wake up. little know nothing that acts like a know it all.
