Dell Dimension 5100 Network Card Issue

I have a Dell Dimension 5100. We just got broadband set up and it would not work correctly. It works with another laptop - but does not with with the PC. After hours troubleshooting with the ISP, they say they think we need a new LAN/Network card. I called Dell to ask about this and they said we need a new motherboard.

Can anyone think of anything else that could be causing the internet issue apart from the network card?

Also, is the network card a part of the motherboard? Is it really necessary to get a new motherboard if it's just the network card that is not working & the computer is working fine otherwise?

    Thanks for all your help so far. We were trying to set it up wired and the laptop worked when connected with the wire also. The lights were all green - everything seemed to be working fine from the modem side of things- but we just couldn't connect on the PC.

    So, if I understand the other answers correctly, we can buy a stand alone LAN card and connect it to the the PC? Is that easy to do?

    Badically we are looking for the cheapest solution - Dell said they can get a guy out to fix it for e350 - but a new computer would only be around e450 ... so maybe we should just forget it & get a new one.

    Any advice is really helpful - thanks :)

    Is the Dimension setup via wireless or wired? When you say it works with another laptop I need to ask if the laptop was connected via a wire or wireless?

    Assuming you are wired, once you plug in the network cable, do you see any lights? Amber/Green blinking in the back?

    To answer the question if it is built in, the answer is... it could be. Some have them built-in and some don't. However, if is is built-in you can add a network card to your machine and use that. But let's work on the issue as it stands now.

    Looking for your reply.

On your dell the lan card is integral with the motherboard.
go to your device manager in the control panel and find your ethernet card. you will see it with a yellow triangle , right click it and update driver software.
if it doesn;t find a driver , write down the ethernet type and model specs and search the internet or dell support forum for the driver.
reinstall the lan driver and see if it works.
also: some ethernet configurations are not compatible with some isp's. i doubt that for your dell but there may be a driver patch available to bring your driver up to date.

    You can go to Best buy or any store and buy a 10/100 ethernet PCI card for pretty inexpensive.
    open the computer and plug it into the Open PCI slot and put the screw in holding it in place.
    close the box hook it back up and turn it on.
    It may install the drivers automatically but if it needs put in the cd and point the driver install to the drive.
    then try your internet

    Well after you plug your cable in of course

Commonly its plug and play when you hook it(broadband) in the LAN its just automatic. Could be LAN driver issue or so as they say.

Could be the network card is built in with the motherboard but you can use another Lan card and plug it in a PCI slot then install the driver. Just disable the built in one to make it sure it doesn't conflict with the new one.

Then set everything to auto detect.

What kind of sound card do I need? I can't get any

The dimension 4600 has an integrated sound card, but if that is not working and a driver update does not correct the issue, then any sound card that used a PCI interface will work with that system.

Dell Dimension 5100 won't start with new FireMV 2400 PCI Express video card

Did you check to make sure the video card is installed in the right spot? Has the onboard video card been disabled in Windows - and when you say it will not boot, do you mean physically no POST. Do you get any error codes? If you can get into the CMOS (Bios) Setup screen - change the primary display adapter from the onboard to AGP, PCI, or PCI-E depending on which card that is. Use this information at your own risk - hope it helps.

No videon

it sounds like an issue of driver installation order. If not installed in the correct order, the drivers may not function correctly. The correct order is:

Desktop System Software
Chipset Utility
Video Driver
Audio Driver
Modem Driver
Network Driver

My suggestion is to do a system restore to the 1st available restore point (The one created at boot after you reinstalled) then install the drivers in the correct order. (NOTE: Before you can play a DVD, you will have to install the DVD player too)

Wireless internet

you need to get a PCI Wireless card or a USB Wireless adapter, if you are talking about an 802.11 wireless router.

If you are talking about Sprint wireless Broadband or the link (WWAN service) you'll need a USB WWAN adapter which are available by all major Wireless vendors (Verizon, Sprint, ATT etc(
