Greetings. A few weeks ago, there were lightnings here in our place and our laptop was on and connected to the Internet. My brother left it just like that and later on he found out that it cannot access the Internet anymore. He told me that the PCI (or something, I don't know what that is) is probably not working because when he connects the modem, the light on the port does not blink. He is thinking of opening it so that he could see what needs to be bought because he's guessing a hardware was destroyed. Is he right? He's not good at these things as he's just 17 so I'm worried about letting him open and check the internal of the laptop. Any suggestions? I hope we can fix the problem.

Thank you so much in advance.

Hello janinaji,


I think we can help you with your issue but it sounds to me to be network related. I am going to suggest to one of the mods to have it moved to the correct thread. I'm not too sure about the WNIC being fried as opposed to it being router/modem or possibly settings related.

Hang in there and hopefully by moving it to the right thread we can get you some assistance.

Good Luck :thumbsup:

Hello bwest0703,

By being network-related, does it mean that other computers/laptops cannot use the modem? Because I'm using the modem right now on another laptop, so I think the modem is doing fine.

Thank you again. :thumbsup:

The modem can be working properly...but if the NIC (network adapter, to which the modem is connected) is not working properly, then there will be no reception of the signal from the modem.

Since this is a laptop, there is only so much that can be done (IMO) about possible hardware failures...other than to attempt to verify such.

Start/Run...type devmgmt.msc and hit Enter.

Click Network Adapter, then double-click the detailed item revealed for that.

Click Driver tab, click Uninstall button.

Reboot the system.

Start/Run...type devmgmt.msc and hit Enter.

Is there a yellow marking by Network Adapter?

Hello. Thank you Louis. I found two items under Network Adapter: Atheros AR5007EG Wireless Network Adapter and Marvell Yukon 88E8039 PCI-E Fast Ethernet Controller. I uninstalled the second one.

What yellow marking should I look for? After rebooting, the lights beside the network adapter weren't blinking, but after a while, the laptop found it (Marvell Yukon..) again and the lights resumed blinking.

System manufacturer and model?

If you see no yellow or black or red markings in Device Manager by any item...that's a good thing :thumbsup:.

The Marvell Yukon is your ethernet connection, requires a wired connection. Do you have a wired connection or is it wireless?

Take a look in Device Manager now...just to see if there are any markings beside either of the two network adapters.

Then go to Control Panel/Network & Internet Connections. There should be an item for Network Connections. Pause the mouse on it...tell me what is listed at the left column under Details.

Louis

Hello, Louis.

It's Acer Aspire 4715Z series, Model No.: MS2220. It has a wired connection.

These are the items next to Network Connections: Local Area Connection 7 (which we are using), Nokia 5800...USB Modem (OTA) (used by my brother through his phone), Sun BROADBAND BASIC, Sun BROADBAND STANDARD (the last two were used by my sister before), and Wireless Network Connection.

The Local Area Connection 7 continuously tries to acquire network address and then it says the network cable is unplugged.

Hi Bruce,

Yes, that's it, Acer Aspire 4715Z. My brother keeps on saying it could be the PCI, whatever that is. Thank you Bruce. Hope you can help us with this.

Regards,

Jani

Please download the pdf (adobe reader has to be installed to view) version of the owners manual and save to your desktop.

There is a utility called Acer eNet Manager that should be installed on your laptop.
Please read page 2 of the manual I asked you to download above. It explains how to setup a network connection, the utility should do everything automatically for you.

If this fails to work, there is a chance the hardware related to the Ethernet card is damaged.

You could try turning on the wireless function to see if it also has failed or works.

If the Ethernet card has suffered any damage, it is best to leave the repair to a qualified repair tech center, who will offer you a warranty on parts, if in the event something goes wrong after the repair.

Bruce.

Another series of tests to try at the command prompt CMD are ipconfig /all or netstat

Being that the Ethernet lights are not flashing either means one or more the following:

Ethernet cable or plug is damaged.

Drivers are not installed for the NIC.

Device is not activated or turned off, either through Windows or the BIOS setup utility.

Ethernet adapter is damaged.

Hello, Chris and Bruce. Thanks for your help.





Chris,

I did what you told me to do and it was successful. It looked like this:

Microsoft Windows XP [Version 5.1.2600]

So, the NIC wasn't damaged?











Bruce,

I'm trying to look up where the acer eNet manager or the Acer Empowering Technology program is located but I can't see it.
I also did the test you wanted me to try. I typed ipconfig/all in command prompt and it looked like this:

Microsoft Windows XP [Version 5.1.2600]
© Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\admin nahera>ipconfig/all

I also typed netstat and it simply looked like this:

C:\Documents and Settings\admin nahera>netstat

Active Connections

I'm thinking it's the ethernet port that was damaged, but just a guess.

These two entries below show that you have both an Ethernet adapter and a wireless adapter installed.

Ethernet adapter Local Area Connection 7:

Media State . . . . . . . . . . . : Media disconnected
Description . . . . . . . . . . . : Marvell Yukon 88E8039 PCI-E Fast Ethernet Controller
Physical Address. . . . . . . . . : 00-1D-72-19-9A-77

Ethernet adapter Wireless Network Connection:

Media State . . . . . . . . . . . : Media disconnected
Description . . . . . . . . . . . : Atheros AR5007EG Wireless Network Adapter
Physical Address. . . . . . . . . : 00-17-C4-16-2F-1E


I put the brand name of both your adapters in Bold print.

What we need to do is make sure you have the proper drivers installed to make the device work.

Let me do some research to see if there are updated drivers available and perhaps I will link you to those.

For what it is worth, windows is still seeing both the devices as being there, so lets see if installing a driver might get it working again.

Bruce.

Here's the driver link for Marvell Yukon 88E8039 PCI-E Fast Ethernet Controller.

Marvell's support web site. http://www.marvell.com/support.html Look for the word DRIVERS for PLATFORM choose Windows XP from drop down menu than this number 88E8039 on the second drop down menu for the PART NUMBER.

Then choose the driver for XP 32 bit, sorry, I can not link you directly to this download, it won't link there properly, you have to get there on your own computer.

This adapter also has Vista and Windows 7 drivers available for it as well, so at least you now know this NIC has Windows 7 support in case you ever decide to upgrade.

Bruce.
