Dell 8100 ethernet will not connect off the port replicator

Ethernet runs fine off the MX-01E530 port replicator which has its own ethernet connector, but the laptop shows "cable disconnected" when the cable is plugged into the laptop. Any hints?

    Dell 820 Works fine on ethernet port on back of PC, but quit working on the ethernet port on the port replicator about 3 days ago.

    The rest of the port replicator works just fine.

Let me give it a try ...

There are a few possibilities but i'll cover 2 of them :
1. There is a program that comes with your DELL that will save battery life by turning off your Network Card (LAN) I forgot what is the program name. But usually when you plug the power cable out, there will be notification at bottom right corner of your screen that told you so.

2. I don't know if your port replicator connected to power adapter (is port replicator = docking ?). The fact that your LAN connected when it's on port replicator make my first conclusion more acceptable. Since port replicator got it's own power adapter, it will just turn the LAN on.

Now if you want to check if thats the cause, just plug your notebook to it's power adapter/charger and plug your LAN Cable in. If it works than the problem is the nasty program from DELL.

If you want to disable the program just go to Startup Tab at msconfig and disable (clear the check mark) for that nasty program

Hope it helps

Can I disable wireless and connect with ethernet cord and modem, for work do not want remove wireless cord, in the day want to be able to use my wireless.


Are you talking about direct-connecting via Ethernet to a cable or DSL modem? You shouldn't have to disable wireless to do that. If the cable modem has an open Ethernet port, you should be able to run a straight-thru Ethernet Cat-5 cable between that port and the Ethernet port on your laptop. The laptop should recognize that it is connected to the modem through the direct connection. Check the manual for the cable modem or information supplied by your ISP for connection details. You may have to do some setup on the modem to get an Internet connection, like having your ISP 'activate' the modem. Just be sure your Ethernet cable is a straight-thru, standard Ethernet cable, and not a 'cross-over' cable such as is used to transfer data between two computers.

Hi lesstravelro...
No, the printer does not connect to the ethernet port.

Before you hook your printer to your laptop besure to run any softwear that came with the printer.
I would also recommend that you go to the Manufacturer's website for updated drivers for your printer.
Your printer will have a printer port or usb port on the side/back of the printer to plug the printer cable into the printer.
You will plug the other end of the printer cable into a usb port on your laptop.
Please take time to rate me thumbs up

I have acquired a Dell latitude XPi CD Laptop without user instructions...where do I connect the phone cable please


**** http://support.dell.com/support/edocs/systems/ptcd/document.htm **** Hey from Texas! I used this link and found your manual . Click on the second link (Reference & Troubleshooting Guide) it's a Pdf. file so if you didn't want to download it, your browser with the help of a reader app like Foxit or Adobe should open it up online. The page you want is 1-1 and 1-2. There was no phone jack but I did see a pci slot, and two nifty infrared ports. It said it came with a whopping lightning fast Pentium that ran at 150 Megahertz. Pretty cool for back in the day . I'd bet it a buyer a small fortune,being modern technology and all. On page 1-3 it calls for an 'advanced port replicator'? that takes a Ethernet connection for networking. I assume that's the final answer. Phone no, Ethernet only with some add-ons. Sorry I was so long winded but it was some cool reading. :p Rate me if I helped. Thanks.- jmattes Good luck...

Dell Precision M70 - Ethernet Port not recognised


if the laptop is wifi enabled there is no need o connect it through the Ethernet cable it will just pick up the signal and you will have to put in the pass code. Even if you want to connect by Ethernet cable you should be able to just plug it in and get on the internet.
if the problem is you don't know the pass code it should be on the original modem manual.

Can I use a 1978u replicator with my 8100 if I remove the locking arm?


try to turn it on ... it should have no problem with the "electronics"

if you got message that the docking is not compatible, then you will have to flash your notebook bios to the latest 8100 BIOS.

If same case still happen after updating your BIOS, use C840 bios (which AFAIK will not harm your notebook). It will then read the docking/port replicator correctly.

Both BIOS can be found here

Give it a shot ...

Ethernet in Docking Station


Some docking stations require device drivers in order for the ports to work. Try the link bellow for any drivers that are for the docking station. They're generally under utilities or applications, but could be else where. If there are no drivers, or if they don't work, then I suggest having the port checked. It could be a bad port. Also try any updated ethernet drivers for the machine, if it uses the machines integrated ethernet, then it could be the controller driver as well.
