Network adapter lightning damage

post #1 of 9
Thread Starter 
Sorry if this is in the wrong section

So there was a thunderstorm last night and it apparently broke
a) my modem
b) probably my motherboard's intergrated network adapter
c) something from my router (wan port?, it works occasionally, then it doesn't)


The adapter doesn't show up in device manager, the lights don't light up near the connector, router's/modem's port light doesn't light up when connected (tried with multiple modems). So I'm pretty sure it's busted. The computer seems to work fine otherwise.

I reset the CMOS and updated the BIOS to newest version. It made no difference.
Are there still some things I could try? Or is it dead?

When I reinstalled drivers I got this:


Also... a replacement pci adapter won't fit because of my gpu cooler and small board. Are there any other options (except for going wireless)? Some sort of an USB thing maybe? Or do I have to get a new motherboard?

Thanks for reading

Yes you can get USB Ethernet NIC's such as this:

But I do find it interesting if a lightning storm sent a surge down your network cables that more damage wasn't done.

You are lucky the PC boots at all. Most lightning strikes result in blown motherboards and power supplies when it hits an external peripheral or network connection. Most network chipsets have an internal fuse in case somebody accidentally plugs-in a telephone (90 volts AC when ringing) into the RJ-45 jack. When the lightning strike hit, it probably blew the fuse and took out the NIC chipset in the process. It can't be repaired, you will (at a minimum) need to replace the motherboard or move stuff around and use a PCIe, PCI, or USB Ethernet adapter at this point.

Thanks for the replies guys. Are those USB things just as good as the onboard NIC? And should I just get the cheapest one I can find?

edit. this and this no win7 support? are about the only ones I can find locally.

Also... one thing I find interesting is that the other computer connected to the same router (with a 15 meter cable) was left unharmed.

USB 2.0 Ethernet Adapter will give you a steady 200-300 Mbit/sec worth of bandwidth, which is more than enough to match your Internet connection. I wouldn't want to use USB Ethernet for a file server or media server though, even if it's just for home use.

If I moved my GPU down to the "PCIe 2.0 x16 (x4 mode)" slot, then I could fit in a PCI-E network adapter. This would be about the same price as the USB thing. I guess it would be a better option?
How much does moving the GPU from x16 slot to x4 mode slot affect the performance? I remember reading somewhere that it's not that big of a deal.

Are you doing anything that saturates a gigabit link? If not then just get a USB NIC. It will run at around 300Mbps.

My internet is only about 13 Mbps down and 2 up, so I guess not. I don't move a lot of stuff in the LAN so that won't matter.
So I guess it would be this one. Would it be sufficient? Looks kind of cheap but I guess it should work.
Or this. Looks the same but with a cable.

I wouldn't move your x16 video card down into an x4 slot - you might end up creating a bottleneck. x8 is definitely OK, x4 s iffy depending on your card and the games you're playing.

13 Mbps Internet is well below the threshold of what a USB network adapter can handle. I'd go that route and leave the video card where it is.
