Welcome to Fixya

If your DSL modem is using ehternet cable (LAN cable) as its primary connection. All you need to do is to plug in the ethernet cable at the back of your computer then you are good to go. Please see picture below.

Hi, Thomas.
I see you have access to another computer, that's a good thing.
I am providing you with the link to the Dell support page for the optiplex gx260.
If you go on the site using this link, then all you will need to do is scroll down to where it says network.
Click on it and there is a list of several different pieces of software, some are utilities, but the one you need says 3Com Driver.
It's like the second or third item on the list.
This is the driver for your onboard ethernet adapter.
Download this to a flash drive, then take the drive and hook it into the gx260 and install the driver.
If you can do that, then you will have your internet working once again.

Here is the link:

Now, there is also another way that might work as well, in cas you can't do that.

Open your control panel, and select system.
Next, select the tab that says hardware.
Then select device manager.
Once you have device manager open, go to network adapters, and there should be your onboard nic adapter listed, maybe as unknown device with a question mark, or maybe it's listed with an exclamation mark beside it.
Double click on it, and it will pop up a properties box for it.
Select update driver.
It will ask if you want to connect to the net, which of course you will select no.
Next, it will ask if you want it to automatically install the driver, and once again select no.
Next, select that you will choose the driver for it, (advanced) selection.
Next, it will list probable compatible drivers for your nic.
If it list one that says something like 3com 905, then select that one,this will only be there if there is a checkmark in the box that says show compatible devices.
If it's not there, then uncheck the box.
This should bring up a list of all the different types of devices that can be attached to a computer.
Select network adapters from that list.
Next, in the left hand column, click on 3com, and then there will be a list on the right.
Go down the list and see if there is one that says 905c adapter, or something real close to that.
If so, select it and have it install it.
If it works, it will let you know that it installed properly and that your device is ready for use.
If that's the case, then reboot and allow the settings to initialize, it should then make your nic adapter work, and you should have internet again.

I hope this helps you out, and have a good day.

I put a windowsxp cd in a dell optiplex gx260-to replace windows 2000 and added memory to 512.The network adaptor driver i installed from dell doesn't work 3com or something like had utilities...

on the drivers download page on the dell website it looks like the second one on the networking list is the one you should install, if that doesn't work you might like to ask dell for the right one.

thinking about the memory, to run xp properly you need a minimum of 1G ram, anything less and it will struggle on a fully updated system.

My lan drivers disappeared after formatting optiplex GX260. What do i do?

You'll need to access Dell's Drivers and Downloads page from another computer that has internet access, and supply the Service Tag (or other method of choice) information to obtain a list of drivers for your GX260. Assuming you're using the original LAN card, you'll have to download and install the required driver to restore network functionality from the Dell site (if other than a GX260 LAN card, you'll have to go to the LAN card manufacturer's site for drivers).

There may be more than one LAN driver from which to choose. If unsure which version you have - you'll need to get all of them and install them one at a time until you find the one needed by your machine.

Please rate this reply if it was helpful to you - good luck!

What ethernet driver do I need for dell optiplex gx260. There is no ethernet card. Just a slot for the enthernet cable.

check the Device Manager,
Go to Desktop/My Computer/Right Click/Properties/System Properties/Hardware Tab/Device Manager/look for Network Adaptor/ Expand it by clicking the + sign/Do u c any Ethernet Adaptor there or any yellow ? mark there....

If u dont c any Netwrok Adaptor then u dont have a network card installed in ur PC, if u have one then it will show up there, and if u dont ahve the correct driver or if's not installe dproperly then u will have the yellow ? amrk or an ! mark....
then in that case u will need the corect driver for the card to work....normaly Windows installs the required drivers for netwrork cards.....

Using dual monitors on a Dell Optiplex GX260

You cant.. Unless the nvidia card you added has two video OUTs. Plugging in a aftermarket card causes the motherboard to disable the onboard video..
If your nvidia card has two "outs" then you can use two monitors... most newer nvidia cards support this. sometimes it requires an adaptor, but usually it was included in the box
