guys, i desperately need ur help

few days ago, there was a thunderstorm and it happened to fried both my computers' ethernet port, both my computer was on (was switched off before i went out, powered up by lightning, is this even possible?) both had errors.

okay after i restarted it, everything was fine except the ethernet ports. none were detected (device manager doesnt show)

my question is,

1. how to check if other hardware is affected?

2. i do not want to wait until something fails only to find out about it =(

Additional info,

1. my computer is fairly new (less than 6 months) and it's under warranty, the motherboard's ethernet port is screwed (i probably change the motherboard with warranty)

2. no burnt smell that i notice of. ( i assume the lightning goes in thru the router and reach my computer, but my modem is fine - using unifi, fibre optics can get zapped? )

i dont live in apartment

erm.. the modem i'm quite sure didn't fry.. because all other wireless network devices still able to connect to the modem

thing is.. i cannot even detect the Ethernet port under device manager =(

it won't install the driver..

okay.. let me put this clearly again.

On my first pc, the Ethernet port is connected to the motherboard (onboard ethernet port) the light is still on when I plug out the cable. (i'm not sure if the light should always be on or not) so, i'm assuming the port is spoilt since the light should be off once you remove the cable? windows error msg shows please install driver if you have a network adapter (windows 7) - but cannot install cause cannot detect under device manager - if the port is onboard port can it be detected under device manager under network adapters?

On my second pc, the Ethernet port is a separate card connected to the motherboard (RM50) and doesn't light up even after I plug in the cable. (Card can be detected under device manager and it says device is working properly)

On my modem currently, there is no light on all 4 Ethernet ports. Other than that, all wireless devices are working


I'm probably suspecting the port on my first pc is spoilt and the modem is probably faulty also on the Ethernet cable side.


update : i noticed my first pc's lan port has 2 lights (1 is off, the other is on, yellow colour)
motherboard model is P67A-UD3-B3

no, the modem PORT lights are all off even after i plugged in all the Ethernet cables

there are 4 ports. i plug in 4 cables all off. normally at least 3 will light up

the rest all on

guys.. i trouble shoot already..

there are 4 ports on the dir 615 modem. 2 of them are fried, which the same 2 connected to my both comps killed the ethernet port

guess need to call tmnet to change the modem, as well as claim the giga motherboard warranty..

gonna think of surge protector next..

i tested it with a brand new router..
