Review on 🌩️ APC Ethernet Surge Protector for 10/100/1000 Base-T Ethernet lines with ProtectNet (PNET1GB) by Rob Allen

When I was building my house six years ago, I connected an additional building to an underground PVC pipe with CAT6A. On each page I've added one of these ProtectNet networks. I connected a ground wire to the ground of the house on each side. Ethernet connects my main router to a switch in another building. About a month ago there was a big thunderstorm (which is not uncommon in Florida). I heard a crack. The protectnet in the back building burned down but the equipment was fine but the connection slowed to a crawl until I removed the protectnet. The Protectnet in the house also burned out, but 2 ports on the router died and the LAN port on my set-top box also burned out. As a result, I replaced all faulty devices. about $400. questions without answers. (1) Do they simply wear out over time and need to be replaced regularly? (2) Do they need to be replaced after frying? How do I know they're fried? Is there any indication of when they need to be replaced? (3) The input and output ports are of course not interchangeable, but is the included jumper required or can I use my own cable. JUMPER is too short. (4) Too much guesswork. How do I know that I did everything perfectly after the installation? Due to the many unanswered questions and false assumptions as well as the fact that I have so many device losses, I cannot give this product a good rating. In retrospect, I should have run fiber optics between buildings. So far I have connected two buildings via WDS. UPDATE: I replaced two burned out ones. When I got to the speed test, I tested 150 Mbps with Powernet disabled. I'm testing at 14 kbps while connected. Well it's a joke!
