Try going into the control panel and then into the device manager. Find the ethernet device and remove it. Then re-boot the computer and the OS should re-detect the card and re-install the drivers. Hopefully this will get the card working again. Let me know if this helps.

My acer 4310 connects fast to wi-fi pero pag internet cable na as in ung dsl hindi gumagana


Hi there,


When you plugged in the ethernet cable, does it show on your windows tray (lower right corner of the screen) that the LAN is connected? It should show you "Connected" if you hover your mouse on the LAN icon.

Try also to plug in the ethernet cable to a different port on the router, and that the port number on the router is showing a solid green led light.

If all has been observed and still you cannot connect, look if the network adapter for your lan is working. RIGHT click your My Computer or "Computer" and select Manage. The Computer Management window will open. Click on the Device Manager on the left to show the list of devices on the right. Look for Network Adapters and click the + sign. See if your LAN adapter is not showing any yellow exclamation point. Also, right click on it and select Properties. You should see the device is working properly under status.

Please let me know how this goes. Thank you for using FixYa.

Ethernet connection fails to cable modem


Let's do a little bit of troubleshooting and see what we find out. First I assume that you are using some kind of Microsoft operating system. (if not, let me know.)
  1. You say that the cable is working fine. That's a good start.
  2. If you connect your cable to the GX, do you see an orange (connectivity) and a green (traffic) light next to the adapter?
  3. Did you check your Device Manager to see if the adapter is working? (Right-click "My Computer", choose "Manage" and open "Device Manager".You should have an entry under "Network Adapters". The on-board, standard network card is an Intel Pro/1000MT.
  4. If there is no entry, then the adapter is faulty (or not recognized by the Operating System).
  5. If you have an entry - is there a yellow question mark? If so, then the driver is missing. You can download it from Dell's support page here.
  6. If your adapter is broken, you can always try to find either an external USB-to-Ethernet or wireless USB adapter or install a new network card. See example here. Make sure that you get one that also comes with a small installation frame, so it fits your housing. (look at the pics in the link.)
  7. If your network card is fine and you have a driver already installed, it could be your network settings. Is your adapter set to get an IP via DHCP? Open your Control Panel and Network Connections. Do you see an entry there? If so, right-click it and choose "Properties". Scroll down to "Internet Protocol TCP/IP" and double-click it. Are both radio buttons set to "Obtain...automatically"? If not, change that and click "OK" to close all related windows.
If you have any more questions or need more help with any of the steps above, just come back here and leave a comment - I'm happy to help.

First check whether the adapter is working or not?
In the device manager you are able to detect the adapter, that is a good sign.
When you go to the adapters properties, does it say working properly,
If it is , then you just need to connect to the wireless network and the light will lit up

Cannot get on the internet


light should be green instead of orange. check in your device manager to make sure the driver is installed for the ethernet adapter, if it is then you know the motherboard is bad cause the ethernet adapter is connected to the motherboard.

If the driver for the ethernet adapter is not installed then go to support.dell.com and from there go into the drivers section, type in your model and then download the driver for your laptop and install it and then see if you can connect. If you do this and you still can't connect then that still means the ethernet adapter is bad and the motherboard would still have to be replaced.

When I connect the ethernet cable to my tower, I gave an orange light. What could be causing this to happen?


What Orange light are you refering to? You have an orange and green LED on the block of the Ethernet connecter, if the cable is plugged into the plug and the other end is terminated into another deive such as a modem,bridge,router or switch the orange light(led) should come on as that indicates a valdi link hence being called the link light, the green light(led) indicates data being received or transmitted. If orange flash with sparks(bad) from the plug it means there is power on the cable..very bad as this could be due to the ethernet card that is faulty or the device on the other end of the cable is faulty.

Have you checked your ethernet connection device? Is there a green light blinking from where you plug the cable into your computer? Do your have an on board device or an ethernet/wireless card?
What error messages (if any) are you getting?
Go to device manager in system properties ( logo + pause/ general tab/ hardware/ device manager) a quick short cut, and check to see if your have yellow exclamation mark or red x in "network adapters". Make sure your device is listed. If you see it right click/ properties/ under device status see if it is enabled and working. If not click to enable it.
Maybe a little more info on your problem like is there an icon on taskbar (bottom right by the time) that shows a monitor icon with/without an X on it?
You might have to run the internet connection wizard. If all fails try opening the case & removing the card (if thats what you use) and re seating it. Turn pc on & look for a "found new hardware" balloon on bottom right/ follow instructionsl.
Sorry for all the questions but this should leave you with 1 or 2 other options anyway.

Networking Problem


It is not uncommon for the network adapter to become faulty and stop working. Since you've checked the cable and it is still listed in device manager as working properly, I would add a PCI ethernet port to your computer, then disable the faulty one in device manager. They can be picked up for around $15 locally and even cheaper on the web.
