Burned out Ethernet Ports?

Recently after a storm at my house, the power was knocked out for a minute or so. I was on Xbox Live (Netflix), and the internet kept disconnecting (3 or 4 times it would disconnect me from XBL, but then I could log in again). Finally I wasn't able to get on XBL at all, and noticed my other computers were also unable to get online. The router/modem (Actiontec GT784WN) was also out (didn't register a connection to the internet, only the DSL), but I got that to work again (lighting up the internet light). I was able to get the wireless network to work again, but the wired connection only works from 1 of the 4 ethernet ports on the router, and only on a laptop that wasn't plugged in during the storm. I assume my desktop and xbox both got their ethernet ports fried (red light on the desktop Ethernet port and xbox 360 keeps thinking there is an ethernet cable plugged in when there isn't). My questions are as follows:

For the desktop, which has an ethernet port built onto the motherboard, would be able to just buy a regular PCI NIC ethernet card and attach that go get internet?

As for the 360, is my best option to just send it in to Microsoft (it’s under a year old), or is there an easy fix?

And as far the router, I have tested all 4 of the ports and only one of them work (the #1 port), but could this be because I only have one device to hook up to it? I doubt it is the case, but if I only plug one device in, and plug it into the number 2 or 3 or 4 port, will it not function unless the previous plugs are being used? Or am I right that the other 3 ports are fried and it just so happens the #1 port is ok?

Also, I had surge protectors hooked up, but apparently they didn’t work (they were cheap). Do I need more effective protectors, and what kind of measure should I look for?

FYI: my desktop is connected to the router through a powerline ethernet adapter.

Thanks in advance.




UPDATE: I did get a new NIC card but it still isn't working. it acts like it is installing the driver software for the NIC card and does recognize it, but doesn't connect to my network. Also, the monitor stopped working. I've tried several monitors and none of them work. is there a quick fix to that?

I've had a similar experience. Every Ethernet and HDMI port in my house that had a cable plugged into it (power on or not) was fried by a nearby lightning strike. Surge protectors will only protect against power surges - or were you running Ethernet cables through a surge protector's network port? I now use dedicated Ethernet surge protectors, which are not cheap largely because not many are sold.

I have a 8-port switch with five working ports. Three had cables plugged in that fateful day, three are dead. I never heard of ports 1 to 3 having to be populated for port 4 to work, so I suspect you now have a one-port router.

A plugin card will work fine for the desktop. Good luck with the 360; I don't think that being hit by...

The strangest things about my lightning strike are a motherboard that works just fine except for Ethernet and sound being burned out (were the connections fused? Is Asus that smart?) and a television that used to be hi-def but is now standard resolution because the HDMI port is dead.
