There are many ways to protect network devices from lighting. I have created some points that can help you to protect your entire indoor network device during lighting and thundering issues.

1:  Use the EHT and Lighting Protected Device only:

Always use the Network device having an inbuilt EHT protection circuit. If you already have many network devices that don’t have any EHT (Extra high tension) then you can use Ethernet Surge Protector (ETH-SP)  before directly connecting to the device wire coming from outside. Whenever any thundering and lightning comes into the device it will go through EHT protection and will not damage and burn the hardware.
