What do you mean designed for it? As far as the miner is concerned it is Ethernet. Nothing special that it has to be designed for. The miner has no idea (nor does it care) that downstream packets are traveling over a wireless link, a copper link, a sonar link, a tin can link, or smoke signal link. It sends Ethernet (100BaseTX) packets and gets back Ethernet packets. That is the whole point.
So, with that in mind, I think we'll need a wifi router on each side? The cable/internet provider gives you one with the service, which doesnt care what wifi device is connecting, but in our case, it will be another wifi router, hardwired to the miner, instead of a dongle or built in wifi...
Am I on the same page now?
