Along with the new 3rd generation Fire TV, Amazon has released their own official Fire TV Ethernet Adapter that also works with the 2nd generation Fire TV Stick. It’s a fine adapter if all you want is to add Ethernet capabilities to your Fire TV or Fire TV Stick, but most people will be much better off buying this UGREEN Ethernet Adapter w/ USB Hub along with an OTG Adapter.
Amazon’s Ethernet Adapter is the best option if all you want to do is add wired connectivity to the Fire TV 3 or Fire TV Stick 2. I recommend it over the similar UGREEN Ethernet Adapter that I recommended in the past before Amazon released their own adapter. The problem with Amazon’s Ethernet Adapter is that it has OTG capabilities built-in, which means you cannot use it with additional USB devices.
If you want to connect additional USB devices to your Fire TV 3 or Fire TV Stick 2, the UGREEN Ethernet Adapter w/ USB Hub is the way to go. It gives you an ethernet port as well as 3 additional USB ports. I’ve verified that it works perfectly with both the new “pendent” Fire TV 3 and the newer Fire TV Stick 2. Fire OS, the Fire TV operating system, recognizes the UGREEN adapter in the exact same way as the official one from Amazon. No ethernet adapters work with the 1st generation Fire TV Stick unless you root the device.
Since the UGREEN adapter doesn’t have OTG capabilities (which is a good thing), you’re going to need to use an OTG adapter to connect it to the Fire TV or Fire TV Stick. Either this Generic OTG Adapter or this Angle OTG Adapter will work. The generic OTG adapter gives you a bit more cable length and flexibility with positioning, but the angle OTG adapter gives you a cleaner setup with fewer cables. I’ve verified that both work with the Fire TV 3 and Fire TV Stick 2, so the choice is yours.
By having a USB hub built into the ethernet adapter, it allows you to connect things like USB drives, keyboards, mice, game controllers, and more. Amazon’s ethernet adapter does not allow for that flexibility. If the 3 USB ports on the UGREEN adapter are not enough, you can connect any USB hub to it to gain additional ports. If the devices that you connect to the UGREEN adapter require more power than the Fire TV supplies, you can optionally add this UGREEN Power Supply which connects directly to the ethernet adapter.
The UGREEN Ethernet Adapter w/ USB Hub and OTG Adapter together are currently less expensive than Amazon’s own $14.99 Ethernet Adapter. The last time I wrote about new ethernet and OTG accessories that can be used with Fire TV devices, the increased traffic to those products caused their prices to increase. If that happens again, you might find the UGREEN Ethernet Adapter w/ USB Hub on eBay or the OTG Adapter on eBay to be less expensive.
