Laptop will not connect to Internet via Ethernet

by user60114098 / December 9, 2008 11:32 PM PST

I've got a used laptop, which connects wirelessly to the Internet when I'm on the road but when I hook it up to my DSL modem at home (no wifi) via Ethernet cable it will not connect. Any ideas?

- Defective hardware.
- Not the right driver installed.

Did it ever work? What changed since than?
What does Device Manager tell about the component?

"Did it ever work? What changed since than?"
Since I've had it, it's never been able to connect to the Internet at home thru my DSL Ethernet connection.

"What does Device Manager tell about the component?"
Which component?

From your saying "a used laptop" I gather it is second-hand. Can you contact the previous owner to see if he can tell more on the history of the machine?
It's possible, for example, he sold the machine because the Ethernet didn't work and he couldn't solve it.

The 'component' is the Ethernet controller, that (for a laptop) most likely isn't a separate card. Device Manager might show that the correct driver isn't installed. Then download that from the makers site or find it on the driver CD that you might have.

The obvious work-around is to buy a wireless router for use at home. That's a no-problem $60 solution, as shown on

Not possible to contact the previous owner.

In Device Manager I could not locate "Ethernet controller" but in "Network Adapters" I did find "Broadcom Netlink Gigabit Ethernet", which it says is working properly.

Also, "Network Adapters" was expanded showing 3 items with yellow exclamation marks "WAN Miniport (IP)", "WAN Miniport (PPPOE)" & "WAN Miniport (PPTP)". Under "Properties" for all 3 it says "Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory (code 38)"

So Ethernet adapter is working right, but the WAN miniport drivers (whatever those may be) aren't.

You might like to read through:"Windows+cannot+load+the+device+driver+for+this+hardware+because+a+previous+instance+of+the+device+driver+is+still+in+memory+(code+38)"

In it is recommended to reboot (which probably doesn't solve the problem) or to run the Troubleshooting Wizard (which might help).

But I'm afraid you won't be able to solve this without the right drivers for this specific laptop. Download them from the makers site (you didn't tell anything about it) if you don't have them on CD. Then delete these 3 devices from Device Manager, reboot and reinstall these drivers. Success isn't guaranteed, however, even if you have the right drivers.
Returning the laptop to factory conditions by using the System Recovery CD's you have (if you have them) might be the best solution.

So, all in all, I think that buying a wireless router is by far the most easy solution.


The only way to solve this would be to

Reboot (did not help)
Troubleshooting Wizard (tells me to uninstall and reinstall the device manually, which I am not real comfortable doing and don't know where to get the device or what device to reinstall)

BTW...The laptop is an MPC Transport T2300

Some DSL modems require you to install PPPoE software. I can't tell if yours needs this or not since make and model of the DSL modem was omitted.

STOP! Do not fix this without the full details.

That's why I supplied the link.

To tell if it's in bridge we have to use the manual and follow it's instructions. Your posts don't have the detail for me to guess the answer. But I'd prefer not to use bridge mode.

I can't tell how you use you dsl currently.

For example, if I want to move the ethernet from one machine to the next I would turn off that modem, move the cable and turn the modem back on. Sorry but I can't tell from your posts such detail as to bridge or not.

It shows how to configure bridge mode but still could not figure out how to tell if it's in bridge mode currently or where to get the PPPoE software, if needed?

What info do you need to tell if it's in bridge mode & how I use you dsl currently?

The PPPoE software is from your ISP.
by R. Proffitt Forum moderator / December 12, 2008 12:46 AM PST

As to bridge mode that is what you'll have to tell me. I supplied a link about your modem so you could explore its settings. I know some think it should be easier.

Typically when you connect

an ethernet cable a green light will shine showing there is a connection.

So you DSL modem has a router built in ?
Now it could be the modem isn't functioning properly or the Ethernet card is bad.
It could also be the cable. Cables are cheap so you could test it first. You could test the card if you go somewhere that you know the modem or router work you could eliminate the card.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
