bit_user LOL, this is why I have my cable modem on a separate UPS. Then, the Ethernet cable goes through a grounded Ethernet surge protector to connect to my router, which is on the same UPS as my main PC setup. And everything that's electrically connected to my PC is plugged into the same UPS that it's on, including my audio system. I think this is the one I bought, quite a while ago. It seems to pass a 2.5 Gbps signal just fine: https://www.amazon.com/dp/B00805VUD8 It's grounded to the UPS which the cable modem is plugged into. Reply
TechieTwo Lightening can follow any electrical path and cause damage. I once experienced leghtening hitting a 120v wall outlet circuit blowing the recepticle right out of the box. Reply

Yeah, depending on how close the strike is, there might be nothing you can do. However, the law of probability says that most lightning-related power surges will not be that close. In which case, the level of precaution taken can make all the difference. Reply
dwd999 The unanswered question is whether or not the computers were on at the time of the strike. When I had my strike in 2017 my computer was off, so the strike only blew out my cable modem and router, didn't go down the lan cable. No big deal; but it also blew out my garage door opener and the circuit board in my furnace. Those were expensive! Reply

Lightning is scary stuff. When our house was hit (antenna), it exploded the braid on the coax all the way to the pole. It put a burn mark on the house where the coax was run. It MELTED the ground wire for the antenna. Something (EMP, static, ????) killed an HP41 calculator which was not connected to anything. It fried motors in the AC unit. If it hadn't been raining so hard, the house would probably have burned down from the fire started where the guy wires were attached to the house. Reply

Lighting strike in my backyard a few years ago: Industrial surge protectors and UPSs. UPS/surge protector 1: PC, 3D printer, 3 monitors, 4 port switch. Killed parts – Ethernet port on the PC motherboard UPS/surge protector 2: NAS, TV, cable box, AV receiver, laserjet printer, a few other things. Killed parts – HDMI port in the AVR, ethernet port in the printer UPS/surge protector 3: PC + 2 monitors Nothing killed. Other weirdnesses: Unused and unplugged Invisible Fence control box. The cover was blown across the garage Battery powered laser level. Was OFF. In the middle of a room upstairs, on a tripod. Voltage/EMP through the air apparently turned it ON. Reply
chance2 Looks like he might be lucky the whole apartment didn't catch on fire. Reply
Gururu Not terribly worried about the fiberoptic feeding my service, but I guess the old coax lines running along house siding is risky. Kind of second guessing my ONTs which are connected to my router. Reply

Electricity follows whatever pathway it wants. Reply
