What color are the NIC LEDs when everything is turned on?

* Green = A connection exists to a 10-Mbps network
* Orange = A connection exists to a 100-Mbps network
* Yellow = A connection exists to a 1-GB (1000-Mbps) network
* Off (no light) = The computer is not detecting a physical connection to the network

Thanks for the quick reply.

On the router, the leds were dim or not lit but this is the same when the laptop is connected and working.  Are LEDs on the PC?  If so, where?  

Due to the LED issue on the router, I do have an older router, Linksys EA3000, that I will try tonight.  No chance last night when I first started working on it.  

At work, we are speculating that the oscillator internal to the Broadcom chip may have fried, either from the thunderstorm or otherwise.  Is this chip replaceable or do I need to install a PCI-E card (if it comes down to it)?

Look just right of the RJ45 cable on the rear of the computer.

Not only are all system here on an APC, I also have a small UPS in the wiring closet for router and switches. Something to think about.

Yes, when NICs fail ... system observations are often strange. Remember, only change one thing at a time while trouble-shooting. A PCIe gigabit ethernet card is $20 ... easy fix.

Looks like ports one and two on the Asus router are fried (dim sputtering light).  Installed a new NIC card but the onboard chip will probably work.  

Thank you for the replies.

I know this is very old but I have the same problem with the same circumstances, lightning strike, computer off and on a surge protector-router on and connected.  Pretty much identical.  The LED is off even when connected to a known good source.  Ideas?

I think your onboard ethernet is fried.  Install a separate ethernet card.  Slots are hard to come by but the card I got is very small and I was able to squeeze it in.

On my previous issue my ASUS router failed ethernet ports one a day.  Very wierd.  Finally dumped the ASUS and got a new router.  NOTE: I have fried two ASUS and have moved on to Netgear (R7000) but that was before the latest Linksys which looks nice.

Potentially this might be your issue.  If you have a spare router try that but if you have a R1 Aurora, I think some of the chips/systems are weak.
