Didn't realize that the onboard NIC was USB. That does change things a bit. As to what I was doing, I hadn't decided for sure. I had a few ideas, but they all needed more than one NIC available. One idea was a homebrew router. Of course there are others too, but let's focus on the router idea for now. One thing at a time. :) I've not heard of the Asus RT-N16. Is it a b, g, n, or ac router? How much does it retail for? If I was to do a home brew router instead of a commercial one (I do like to do things on my own, as it's a great way to learn AND I have more control than similar commercial models of my home brews usually grant) it would need to be at least somewhat price competitive. As far as routerboard goes, I admit it's been a few years since I closely looked at their products, but last I saw they wouldn't quite work. First of course is that they keep touting to be Linux compatible, but they come with their "RouterOS" which from my one brief experience is nothing but a Linux core with a whole ton of reworks. Not quite the same thing, and most confusing (caveat: I freely admit this was nearly 10 years ago that I really looked, things could have changed since then). Second, if I wanted to do an 802.11ac router via a routerboard product, I'm not aware of any boards that have the multiple chipsets you would need (Wi-Fi chip, Ethernet, bridge chip) as well as multiple Ethernet ports. I seem to recall one board that had two Ethernet ports, but no Wi-Fi. Now I will also freely state my knowledge of Routerboard is poor at best. So if I'm wrong on any of these ideas, feel free to let me know. :) Also, what the heck is a cubietruck? That one I can conclusively say I've NEVER heard of. At least, not that my mind can conjure up.
