Laptop Ethernet has a constant orange light, no connection.

Is it possible my Laptop Ethernet port is dead?

After I got home today I noticed that the store that passed by caused a short power outage. I knew this because several electronic devices that rely on constant power were reset. Next to be noticed was that my computer had no connection to the internet, and my Ethernet port has a constant orange light on. I proceeded to perform a full network restart for my modem, router, and computer. This solved the internet connection to my router. My roommate was able to connect via an Ethernet cable to the internet on any of the routers ports, but I was still unable. However, I was able to connect to the wireless on my computer. Unfortunately no matter what port, or cable I use my Ethernet port still is unresponsive to it all, and still has the constant orange light.

Any steps I should take to help fin out more on this problem, or a solution is greatly appreciated. Thank you.

To use the ethernet port on your laptop, it's wireless must first be turned off.
Ethernet will not work if wireless is on at the same time.
Similarly, wireless will not work if you've got the ethernet cable connected.

Turn off the wireless on your laptop if you want to use ethernet.

Unfortunately that is not the solution. I just tried that just in case I made that mistake, but it didn't work. As I had stated, I noticed my Ethernet port had an orange light. This light stays on with or without a cable plugged in, and despite if I have my wireless turned on or off. No other change other than the one constant orange light is observed.

Thank you for the attempt.

Yes, it's possible a power surge could have fried some, or all, of the components on your motherboard. This is why a good quality surge protector/surge suppressor is always worth the $20 to $30 they cost. It's worth noting, most of those devices are a "one shot" deal in that, if they do indeed protect from a surge, then they've done their job and need to be replaced.

It is unlikely your network interface was fried by a surge when there is one or more devices upstream of it and those components weren't fried. Which is to say, since it plugs into a router and the router isn't toasted off, the power surge didn't come into the interface from the router.

It's also unlikely a surge through the computer's power connection caused the network interface to fry. You'll notice I said "unlikely" and not "impossible"

Having said all that, from what you're telling me, you could very well have a problem with the device. To check, I would uninstall it from Device Manager and then reboot and let windows "find" it again and reinstall it. Check and ensure you have the most up-to-date drivers installed and see if it doesn't work. If not, then it's possible it's fried.

The good news is, if your computer has a free expansion slot, it only costs about $15 for a decent NIC (network interface card) and they're easy to install. Simply shut your PC off, unplug it, open the case, remove the cover from the exansion slot and install the card while keeping your body grounded to the frame of the case so as to avoid an electromagnetic discharge. Typically when working inside a computer, I keep my forearm in contact with the frame of the case. Always touch the frame before touching anything inside the case or pulling the new component out of the antistatic bag.

I am currently using my laptop to make these posts. The wireless works, but the hardwired Ethernet port does not. I have a slot on the side of my laptop that I might be able to use to connect an adapter to for another Ethernet port.

I was wondering. Does the Ethernet and the wireless use the same internal card for processing?

I will try to "'uninstall it from Device Manager and then reboot and let windows "find" it again and reinstall it.'" I will also check to see if my drivers are up to date.

Thank you, and my results will be posted later today.

Typically, network cards have a small "brain" on them but do most of their processing through the CPU. The issue with having a wired and a wireless connection both enabled and connected is a Windows issue, not a hardware one. Windows tends to throw it's hands up in the air when you do that and does nothing until you disable one or the other. Luckily UNIX and Linux don't suffer from that problem

Hopefully reinstalling the device will work. If not, and that slot you mention is a PCMCIA slot (I thought you had a PC, not a laptop, my mistake) and it's empty, you can get a wireless PCMCIA network card to slip in there. It will cost more than the NIC I mentioned above, but not too much more.

I never asked but, if the unit is still under warranty, you should contact the manufacturer's support people.

My computer seems to suggest that I don't have a Wired Networking Adapter.

This is all that is shown...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Device Manager - Networking Adapters
*Hamachi
*Intel(R) WiFi Link 5100 AGN
*Microsoft Virtual WiFi Miniport Adapter
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I proceeded to check with the "IntelĀ® Driver Update Utility" on Intel(dot)com. It had nothing shown under the "Wired Networking". I apparently no longer have a Wired Networking Adapter according to this information.

And now I have another issue that has popped up pertaining to my internet connection. On the chance that this might help my Ethernet connection, I will share the problem here.

My Ethernet is still unresponsive, and still has the orange light with or without an Ethernet cable in it (currently no cable is plugged in). Only today has this new issue really shown itself with using my wireless to access the internet. My connection keeps dropping to little or no connection every 5 minutes or so. Sometimes there is no connection for several minutes or even longer. Disconnecting my internet through my start bar helps sometimes, but not always.

Any Ideas as to what might cause this problem?

Here are some troubleshooting steps to try:

1) Check for more up-to-date drivers for the device. If there are newer ones apply them.
2) If #1 doesn't fix the issue, you can try uninstalling the device from Device Manager. Once you're done so, reboot and let windows "find" the device and install it.
