I have a Node 2i, it works very well with my WiFi. I recently upgraded my router and modem to gigabit (I prefer separates) level, but that was more for streaming video. Never had a single hiccup with the Node on my 5 year old Netgear equipment. My router and modem are in the basement, the Node 2i has been used all over the first floor.
I also upgraded my service to 500 Mbps.
