Or is there a way to do this thru the ethernet?

@BadHaggis good question. I have had mine running for over a year and all is working well. If you want to add a gateway, so your account has two gateways, I think (??) you might be able to have two devices (e.g., iPhone and iPad) download and open each TM Internet app and individually setup each gateway. That would be an interesting setup.

Let us know how it turns out.
