Ethernet cable not registering

RacAtat007 · Jul 19, 2014

Last night I got home and my PC was in sleep mode so I woke it up and noticed my internet wasn't connected. After looking around I saw all my other Wi-Fi and wired devices worked except my PC. The computer is saying no Ethernet cable is connected even though it is clearly plugged in. I did a system restore to a few days earlier and it didn't help. Any ideas?

Try changing the cable. Then see if the Ethernet port's lights are green, amber, or off. http://www.lemis.com/grog/Photos/20111016/big/Ethernet-ports.gif

Since my original post I tried changing the cable and it lights up green when I have both the Ethernet cables I tried plugged in. I also tried reinstalling the drivers with no results. I was very disappointed to find out my mobo manufacturer (biostar) has no customer service phone number so I can't call them. Idk what else it could be?

It is possible that the LAN adapter has failed. You say you tried to install the LAN driver? What did the installation pgm report?

I first tried to repair the driver without any luck then I uninstalled it and did a fresh install and both times it went through like normal bit it still said network cable unplugged. I guess the main thing I was wondering is if the Ethernet port can all together fail?

My other question would be what are my other options? I was thinking of a Wi-Fi card but would prefer a wired connection so are the any external ports or USB Ethernet ports

I didn't follow the grammar of your last sentence. If you are asking for advice for an internal LAN card, let me know what slots are free. If you would like a temporary/permanent work-around, I have used this on several builds and found it to be the best USB WiFi adapter for the money: http://www.newegg.com/Product/Product.aspx?Item=N82E16833704045
Its 8 foot extention cable allows it to be positioned for best signal strength. If you have an N-Band router, it will keep up with a wired connection.

Sorry about the grammer and spelling I am having to use my cell phone to type this since my PC won't connect and my auto correct is bad sometimes. I tried everything I can think of to get the Ethernet port to work with no luck so I went online and found a pci Ethernet card for $9.00 and ordered it. I noticed in the reviews for the Ethernet card must people said they used it for replacing their onboard nic (I'm guessing that's the Ethernet port) so I have high hopes. I would still appreciate any suggestions on how to fix it without taking up 1 of my 2 available pci slots.

It appears unfixable, from our discussion. It's a chip on the MB. Short of a new MB, the work-around you are doing is probably the best you can do if you want to saty with Ethernet.
(yes, NIC is Network Interface Controller. Also sometimes called a network interface card, network adapter, LAN adapter...)

clutchc :

After reading your reply earlier I remembered I bought a cheap Linksys USB wifi adapter a few years ago and after a lot of hassle going to 3rd party sites because Linksys apparently doesn't support their own products, I managed to get it working. I get half my internet speed but at least I can stop my internet withdraw until tomorrow when I get the card. Thank you for taking the time to help.
