How Do I Protect My Ethernet From Lightning?

You are probably aware that the “internet of things” phenomenon has become quite popular. Consequently, all kinds of devices have been connected to your home networks so far, such as dishwashers, programmable thermostats, and security cameras.

The problem with this is that some things are still not connected to the internet—for example, your cable or DSL modem or even some GASP home routers.

Thus, I have created this tutorial to help you protect your ethernet devices from lightning, even wireless! As a result, you do not need to unplug anything in your home if a storm hits.

The best way to protect Ethernet from lightning

Using a “lightning arrestor,” you can protect your Ethernet (and wireless) devices from lightning.

What is it?

An arrestor of lightning is two rods placed between two ethernet cables. As a result, electrons jump across the gap, protecting all devices on the line.

Option 1 – buy an expensive one.

There are several ways to protect your home network from lightning, but you can also purchase a lightning arrestor.

You can choose one according to your cable size. So, for example, if you have thicker ethernet cables (such as the 50′ ones), you can choose one that fits.

If you intend to purchase a lightning arrestor, you should ensure that it can handle the power provided by your modem and router.

Option 2 – Use an ethernet protector

You can also purchase an Ethernet surge protector. They are inexpensive, but they do work. I prefer to use an Ethernet surge protector for this purpose.

It is unnecessary to worry about this too much if you are utilizing a good-rated lightning and ethernet surge protector. However, since Ethernet surge protectors do not contain a grounding wire, their protection is limited to preventing damage caused by high voltage spikes.

Thus, before ordering one, it is essential to confirm that the cable is suitable for your cables, such as cat6a/cat5 or others.

Tips for Cat6a lightning protection

If you have Cat6a cable (the thicker type of Ethernet cable), you will not be able to use a normal ethernet protector. This is because Cat6a does not offer the higher speed of Cat6.

In its place, you will need a “Cat6a lightning arrestor”, which is not very different from the one used to protect Cat6 cabling.

In essence, nothing changes except that it is now Cat6a instead of Cat6. Cat6 Poe surge protectors are among the best lightning protectors for Ethernet.

Not all ethernet protectors are suitable for outdoor use. For example, to protect outdoor ethernet cable lightning, you should only use an outdoor ethernet surge protector.

You can purchase all the necessary products from Amazon or any other retailer of network equipment.

Overall, this is the end of our tutorial on protecting your Ethernet devices from lighting. If you use one of the options outlined above, you should not worry about lightning damaging your network.

I hope you enjoyed it and learned something helpful!
