Fried ethernet input circuit

New Member
I have a Dell XPS 420 (32 Bit) with Windows Vista SP2.

I get DSL internet via Frontier high speed internet service.

Recently my house was struck by lightning and the ethernet input in the computer got fried. The computer still works fine offline but no connection can be established between the computer and the Frontier modem for internet service. Frontier techs verified that their modem is good and that the problem is the computer’s ethernet input circuit.

I took my problem to Best Buy and was told by their techs that Dell XPS hardwires their ethernet inputs to the motherboard…..and that it will cost a couple hundred dollars to have them remove the old input circuit and solder in a replacement. Instead, they recommended a small USB device that plugs into the computer and talks to the Frontier modem and uses it’s wifi function to convert the computer to a wireless connection. I tried it, and sure enough….it works!! (although at a slower speed than the original ethernet connection).

At a shopping mall computer kiosk, I just learned that there are fairly cheap ethernet replacement cards that are available…which will provide a ‘work around’ solution to the fried card (without having to remove the defective card). These cards (supposedly) restore the original DSL speed. The tech told me to be sure and look for a ‘full duplex’ card.

Can anyone shed any light on any of this and possibly make some recommendations?

What's your download speed from the internet?

Also, do you know what type of USB port you were using? USB 2.0?

Also, what is the bandwidth of the USB ethernet card? 54Mbps?

Any new NICs (Network Interface Cards) should work at both full and half duplex and will be auto negotiated by your router so don't worry too much about that.

As for this 'work around' card, how does it connect to the laptop?

Unless you are using a USB 1.0 your internet connection speed should not be affected with your connection being the bottleneck which is normal. That being said you may experience slower transfer speeds between local machines on your LAN.

Many Thanks,
Josh :)

Just buy any one and you are fine.

Josh, a Dell XPS 420 is a full tower.

Ahh fair enough :) For some reason I had a laptop in my head... not sure why :zip:

And internal card like above will yield much more bandwidth than a USB one (bar USB 3.0).

Thank you guys for responding.

Sorry for not mentioning that my cpu is a tower.

Sounds like I need to buy one of the cards. I looked at a couple of the ones listed in the Best Buy link, Several reviews say that I need to make sure that there is a slot available for an add-on card. How do I check that?

Nah, I know hardware to a decent extent, but start asking about the OS, and I run away...

I'm 100% certain you are fine, but pop open the case, snap a picture and post it up for triple confirmation.

Maybe even time to upgrade to wireless if you have a wifi router.

The exact thing happened to me. Do you mind if I ask what exact Ethernet card you decided on getting?

Recently my house was struck by lightning and the ethernet input in the computer got fried.

Okay.. Which did you buy?

It plugs into the White slot near the bottom.

You'll need to install the drivers most likely.

You deon't need to uninstall the old one, but if you want you can gto to the network control panel and right click on the dell adapter, then click and hit disable

Control Panel\Network Connections is where it is at.
