Summary: I have solar panels an myy Envoy was initially connected to the internet via ethernet cable. Due to a change by the cable company, that option was no longer available. Enphase suggested I purchase one of these to connect my Envoy to the internet.
Summary: I needed the wireless adapter for an Enphase Energy gateway. The gateway uploads solar data to a website to be accessed by the solar owner. The gateway only works with this particular adapter.
Summary: Good, affordable usb wifi device. Not for power users (obviously), but has performed very well for my child's computer. I do have to reset it every once in awhile, and the included software feels a bit clunky and intrusive for my tastes.
