Tips for Buying the Right FireStick Ethernet Adapter

The market is filled with micro USB TV sticks and Firestick ethernet adapters. In the beginning, you may have thought you only needed a USB power cable, but now, you come to realize you have too many options to build a wired connection for your FireStick.

So, how should you go about buying a Fire TV ethernet adapter? Well, there are certain features that all good FireStick ethernet adapters have. If you are able to answer the right questions, you can use an Ethernet connection to get stable internet access.

Let’s take a look at some of the factors you should consider as you’re shopping:

Speed is the most important part of using an ethernet port to enable high-speed network transmit rates. So, whenever you want to purchase an adapter for your Fire TV stick, you must ask for the maximum amount of speed the adapter can attain. Most of the time, for a good internet connection, your adapter must be rated around 480 Mbps or higher.

If you find it is not, you might want to seek a better solution to fix poor wireless signal problems.

If you live in a place where there are a lot of obstacles around you, then you should go with a practical ethernet adapter. More specifically, go with a compact adapter to fix your WiFi connection problems.

Replacing your old wireless router with a wired internet connection for your FireStick also means you will need a lengthy USB cable. The same goes for a USB power supply cable if your adapter needs it.

So, keep the cable length of the adapter in mind as well.

Moreover, you should also know that all types of cables are important when it comes to fixing your congested WiFi and maximizing the benefits of a non-wireless connection.

Cables not only supply power to all your devices; they also connect the HDMI port on your Fire Stick to your TV or monitor. Your power cable matters, micro USB cable matters, and the cable for connecting the internet port into your router also matters.

This is important:

So, if you want to connect your adapter to your modem/router with an ethernet cable directly, you should make sure it is of top quality. Overall, pay attention to the cables that come with your adapter.

Ease of Use

An image featuring an ease of use concept

An adapter has to be able to take advantage of streaming sticks micro USB slots. That part of the design is what separates different Fire Stick streaming device adapters.

Generally, all modern adapters have a plug-and-play feature built into them. So, all you really need to do is to take your Fire TV Stick 4K and plug, and your WiFi network router (or whatever device you use for your wireless network), and then plug the Amazon adapter into both to get it to function properly and provide you with a decent network connection. That is pretty much it.

Amazon Fire TV adapters (the good ones, of course) really know how to take advantage of an AC power source and an OTG cable to boost network speed.


To reach good internet speed anywhere and everywhere, an adapter has to be able to fix weak Wi-Fi connection problems in a variety of different ways. It has to show flexibility in different circumstances, especially for people who have multiple smart TVs.

This is important:

More specifically, you need to make sure that you fix your poor network performance with a Fire TV cube adapter that works with all other major streaming platforms. Examples include Google Home Mini, Chromecast, and Fire TV devices, and others.

Charging Ability

Some FireStick ethernet adapter devices come with USB charging ports. You may want to avoid connecting an external USB flash drive with the USB adapter, as that would have no bearing on the wired internet’s reliability.

But moving on from the obvious factors, you will have a better streaming experience if you purchase a FireStick ethernet adapter that has a charging option.

All ethernet devices for Fire Stick will have a LAN port. They would also have a way to make use of the micro USB connector on your FireStick device. But the best ones would also allow users to use a USB wall charger with the device.

Why Should You Use an Ethernet Adapter with FireStick?

There are many benefits of using an ethernet adapter with not only FireStick but many other kinds of micro USB-powered streaming devices for a stable internet.

Good ethernet adapter devices, like the official Amazon FireStick Ethernet Adapter, will usually provide you with the following benefits when you use them with a micro USB-powered streaming stick:

Lack of Buffering

No matter how good your wireless WiFi is, you will always run into speed issues with devices like FireStick and Google Home Mini. This is the primary benefit of using an ethernet adapter. With no buffering involved, your FireStick device won’t ruin your streaming experience by lagging.

Using a wired internet access connection to a device like Fire Stick or Google Home Mini also means that they won’t miss your voice commands. And when they receive them, they will be able to execute all the instructions necessary to complete a given task.

Network Reliability

An image featuring network reliability concept

Most of the time, people will have their router a distance away from the place where they have their FireStick device or smart TV. Depending on the actual distance and the number of obstacles between the router and the TV, a user can receive some very weak WiFi signals.

Devices like the official Amazon Firestick Ethernet Adapter are able to resolve this problem and provide you with reliable internet, so you don’t have to struggle with your streaming connection. Of course, we’re assuming here that you have a fast enough internet package to begin with.

Believe it or not, devices like the Amazon FireStick Ethernet Adapter can provide you with an extra layer of security. They do so in an indirect way, though.

Since in the absence of a wired connection access point, you must always go with a wireless one, this setup introduces a number of security vulnerabilities. Generally speaking, wired connections are more secure than their wireless counterparts.


With wired access to the internet, there is no access point in the air that a hacker can latch onto to gain entry to your network or computer/device and cause problems. Of course, you wouldn’t need an ethernet adapter to get a wired connection if micro USB-powered streaming sticks, like the Fire TV Stick, offered a way for users to simply slot in a wire and be done with it.

As a result, consumers are left with no other choice but to use an ethernet adapter to give their micro USB-powered streaming devices a chance to take advantage of all the benefits of a wired connection.

There are many other reasons why purchasing an ethernet adapter makes a lot of sense, especially if you have an internet package that isn’t particularly fast.

Conclusion: Best Amazon FireStick Ethernet Adapter for Faster Internet Connection + Micro USB Port Support

The best ethernet adapters are able to give you a fast internet connection and form a stable network smoothly and seamlessly.

So, which one is best for you? Ultimately, it will depend on your needs and budget. But in the community, the consensus seems to be that UGreen’s product and the official ethernet adapter from Amazon (both listed above) are two of the best options.

Some give the edge to the official ethernet adapter from Amazon, though. They argue that because the company behind this ethernet adapter is also behind the Fire TV streaming system, it makes sense to purchase this one instead of any other.

The official ethernet adapter from Amazon indeed offers the most compatibility. It works with all Fire TV devices, apart from the first-generation iterations. Even if you have the “lite” version of the latest FireStick (or one of the newer Fire TV Stick 4K versions), the Amazon Ethernet Adaptor should still work with it.

With that said, some point out that UGreen is the better choice since it offers higher speeds and better build quality. And because it comes from a third-party company, it has to offer more than the official adapter to make it in the business.

No doubt, both adapters have some strong positives. But, as we mentioned before, it will ultimately all come down to how you want to use the adapter with your FireStick device, what your budget range is, and whether or not you want more Amazon in your life right now.

If you have read the entirety of this guide, we are sure that you are seriously considering getting yourself an ethernet adapter. That way, you too can enjoy the benefits of a fast connection without any buffering or lagging issues.
