    Default A lightning strike and two questions.....

    First, a question. As far as I know, surge protectors protect devices in case of high voltage surges in AC Power line (e.g. Lightning strike on electric pole) by bypassing it to the Ground/Earth line. But what if the lightning strikes the building instead? Shouldn't the surge then come through the Earth line, being easily transferred from the building structure instead of coming through the Power line?

    Now, the story. Yesterday, a lightning bolt struck our building's roof. The impact was so strong that part of the railing got destroyed. There was no electricity already when it happened, so the electrical damages didn't become apparent until a few hours later. Other flats in our building had heavy casualties, mostly LCD/LED TVs and cordless phones. But thankfully in my flat, the circuit breaker fell immediately when the lightning struck (I guess this proves that the surge indeed came through the power line), and all of the important gadgets were already protected by UPS and Voltage stabilizers. All but one single router. The result, the port on the switch of my ISP's utility box my connection came from got fried. And my motherboard's Ethernet adapter disappeared, even from the device manager. But the router in question is working perfectly fine.

    And now, the other question. The Ethernet adapter reappeared in my device manager this morning. But it now works only in 10mbps link speed, sometimes at 100mbps, but never connects at 1Gbps like before. And occasionally, it disappears for a few minutes, halting all network traffic and then reappears. So, what would be the best action regarding this Ethernet adapter?

    Also, some pictures of the impact location:

    I'm wondering what made that bolt of lightning attract that corner of your building. Shouldn't it connect with a metal rod, the ones which protrude on rooftops to prevent this kind of disasters from happening?

    You should probably buy a new LAN card and those Belkin surge protectors with ethernet pass throughs if this regularly happens in your area.

    Though I doubt the surge protector will do much if a lightning of that caliber strikes again.

    That's the landlord's fault. There were no lightning protective rods. And there were 4 buildings of almost same height around us, but the bolt had to chose our building.

    I guess I have no choice other than buying a PCI Lan card. I wonder if they work with Linux distro's out of the box. And yes, I should probably buy a separate surge protector for ethernet. I think powertree ups's surge protector was enough for the PC, but it doesn't have any Ethernet protection.

    Ahh, that explains it. Tell your landlord to install those protective rods, or another lightning will fry their expensive Samsung LED TV.

    Linux distro should have the proper drivers out of the box, if not you can always check using the make/model on the internet. I'm kinda debating whether to buy these surge protectors or not, I unplug my local ISP connection when it rains outside as a precaution.

    inna lillahi rajiun
    corner of buildings= pillar(?) = pillar with metal rods= electricity conductor = fast travel from cloud to earth. but i am not sure there was a pillar because pillars aint constructed at the very corner of a building. maybe it missed... it happens, it traveled 10Km after all

    Damn son! Shazam must have misfired or sth
    I myself am running a motherboard with a fried built-in Ethernet connecter for couple of years now for the same reason as yours.
    Even though our apartment has a lightening rod on the roof.
    I have been using Internet through another LAN card connected to one of the PCI slots
    That should work. Also like yours, mine does not appear in Device Manager.

    Ok, I'll get a new PCI Ethernet NIC tomorrow. Looks like 100mbps ones are only around 350 taka but Gigabit ones ar above 1.2k. Now I am trying to justify if I really need a gigabit card. My router is gigabit, and it is nice to have a gigabit NIC to transfer files between PCs......but unfortunately my PC is the only non-wireless device in my house that has an Ethernet port.

    It was the lightning bolt. My mom was on that side of the house, and saw the falling plasters and bricks through the window right when the lightning struck. And there was no hailstorm.

    I have seen this kinda thing before. Definitely lightning.

    If the building was properly grounded, nothing should have happened to your devices.

    Unless you really need gigabite, just a cheap pci lancard. if you really wanna buy better onces, buy PCI-E gigabit lan cards that you can use with your next motherboard. I doubt there will be any more PCI on newer motherboards unless you buy the lowest end ones.
    The abuse of greatness is when it disjoins remorse from power.
    Please do not PM me for support. You will NOT get a reply. Post in the relevant forum section.

    First, a question. As far as I know, surge protectors protect devices in case of high voltage surges in AC Power line (e.g. Lightning strike on electric pole) by bypassing it to the Ground/Earth line. But what if the lightning strikes the building instead? Shouldn't the surge then come through the Earth line, being easily transferred from the building structure instead of coming through the Power line?

    Now, the story. Yesterday, a lightning bolt struck our building's roof. The impact was so strong that part of the railing got destroyed. There was no electricity already when it happened, so the electrical damages didn't become apparent until a few hours later. Other flats in our building had heavy casualties, mostly LCD/LED TVs and cordless phones. But thankfully in my flat, the circuit breaker fell immediately when the lightning struck (I guess this proves that the surge indeed came through the power line), and all of the important gadgets were already protected by UPS and Voltage stabilizers. All but one single router. The result, the port on the switch of my ISP's utility box my connection came from got fried. And my motherboard's Ethernet adapter disappeared, even from the device manager. But the router in question is working perfectly fine.

    And now, the other question. The Ethernet adapter reappeared in my device manager this morning. But it now works only in 10mbps link speed, sometimes at 100mbps, but never connects at 1Gbps like before. And occasionally, it disappears for a few minutes, halting all network traffic and then reappears. So, what would be the best action regarding this Ethernet adapter?

    Also, some pictures of the impact location:

    Do ups's have built in surge protectors? I don't own one, but I remember seeing some with some sort of connector. It didn't look like RJ-45 ports, maybe for telephone lines. But there could be modern ups's that have surge ports for network cables. Could look into that.

My router is gigabit, and it is nice to have a gigabit NIC to transfer files between PCs......but unfortunately my PC is the only non-wireless device in my house that has an Ethernet port.

    Yes, they are RJ-11 telephone jacks. My UPS also has one. It also has a 2 pin no-avr no-backup surge-protector-only power socket. I should've put the router on that socket.
