Ethernet port - no light! ?

Question

Hi-

I just got a new Acer X1200 pc a couple weeks ago. When I connected the cable modem directly to the computer, the internet was working fine. However, because I have two computers, I installed a linksys router. At this point, the new computer was getting no connection the internet. I, then connected the pc directly to the modem (as in the beginning), but it did not work either (when it had before). Checking the back of the pc tower, I see that when the ethernet cable is plugged into the port, no green light (or any light) shows.

I checked under device manager and saw that there was an Ethernet Controller listed under "Other devices" with a yellow exclamation point icon. Properties showed that there were no drivers installed. (There was also no "Network adapters" listed in device manager).

I also tried pinging through command prompt but (ping 4.2.2.1) but received an error code 1231.

Finally, I just did a system restore, and saw that under device manager, a network adapter does show (and properties show it to be working properly). There is also no Ethernet Controller listed under an "Other device" listing.

However, the internet is still not working and the back of the pc still shows no light when an ethernet cable is plugged into the ethernet port.

Is the device just plain dead? I find this hard to believe since the computer was bought only two weeks ago -- at least I hope it's not dead. The internet was also working just fine the first couple days.

I also already tried another ethernet cable (with no luck), as well as both tried using a different port in the router and then just direct connection with the modem. Again, no luck.

Any suggestions?


P.S. the OS is Windows Vista Home Premium

Thanks.

Answer 1

Well, to make sure you have the driver installed correctly then uninstall the device completely and then install the driver again. you can get the driver from the manufacturer's website for your model. If it does not work still than you can blame the LAN port and just get buy a LAN adapter if your built in LAN port does not work. The light should come on regardless if the driver is installed or not.

If it's not showing up in Device Manager anywhere, it's probably dead...especially if there are no lights when it's connected to a network cable. We've had this at work a couple times.



Try downloading and re-installing the drivers from the computer manufacturer's website - just in case they're corrupt.



If it's under warranty, call in for repair - if not, just get an add-on network card and use that.

There are quite a few reasons for this happening, First have you ever at present as much as date any anti-secret agent ware and spyware applications? have you ever as much as date the two working recommendations-set, even automatic updates? something comparable exceeded off to me the choice day, it grew to grow to be out the router grew to become into risky. It have been packeting the full organization's community and slowing it down. If the condominium complicated which you stay in has an IT place of artwork or cyber web risk-free practices approach it is going to have close your port down because of the fact of packet broadcasting. yet pondering the incontrovertible fact that it form of feels your port is working, your router could have fried. Even purely a water drop can do it. determine for any cracks or harm to the port. If now not, information on your tower/router could be advantageous in fixing the dilemma.
