liquidcore: It doesn't have the same processing power as a computer, so don't expect to see the full speed. It was just a quick way of seeing if the upload is faster than what you're seeing with WiFi.
Orbis have poor PPPoE performance, so don't expect to see gigabit speeds even via ethernet. You would have seen better speeds with having the Orbi in AP mode rather than router mode.
But that's the thing... 1 week ago before I went through all of this ISP change, I've been using this same Orbi for the last 2 years in Router Mode except it was behind the last ISP's modem and that was getting me 600/400 which was what I'd expect for a 1gb plan (the Orbi I have tops out at 866Mbps anyway on a 5GHz connection). So why is it though that with it still in Router mode but plugged up directly to the ONT now that the Uploads are suffering drastically?
Whenever I finally get the official Skinny gateway I'll try just that and see what speeds getting so at least get more comparisons of if I need to go back to using an ISP gateway and then having the Orbi behind it.
