My pc was ruined, I have had to get new hdd and motherboard. Cpu and ram were saved but lost my drives. External cable was shocked and blew the router and pc parts. I now use a surge for network cable.
I had the same problem with a surge from lightning last year, lightning unusually struck very close, blew the 10/100Mbps switch I had which obviously sent a surge down the line, it blew the network port on my main PC and the sound card too, the connected server network port was completely shot too (broadcom driver package says there is a cable attached that is 23 metres long all the time on that port, even when no cable is in). And that's why I went for a D-Link this time instead of a cheapy chinese thing...
Welcome to the club of line damaged and hdd failed. Same thing happened to me, Mac with hdd encrypted crashed and data lost as well as a line damage on the uplink. Now bound to 3G internet cause of that for the past 2 weeks and still ongoing... meh..
Hate to be rude but they are basically the same thing D-Link are far better than your usual chinese shit, my current router is D-Link.
I learnt the hard way a while ago. Now I unplug everything before I go to sleep at night, every power adapter has a surge protector, and both my PC's run trough a 1500VA APC RS UPS, that has built in surge for land line, network and mains. Ive turned paranoid!!!
Oh believe me, the chinese thing doesn't ever cut out from sending the power directly over the ethernet ports, it's unsafe. And I'm using the D-Link because this baby (http://www.motherwell.net.au/pd/192/digital-energy-match-19-ups-700-3000-va) uses a wee bit too much power...
