Re: Networking

You will be able to access the other computer and visa versa if you have the computers set to share everything which I would not. Also if you are using a wireless router there are security settings for it that can help you be secure with your network. And yes if you do not have the computers secured it would be unwise to have that setup.

Hopes this helps you

My dell GX620 desktop does not power when ever I plug in the network (RJ 45) cable. Also if the system has boots to desktop, and I plug in the network cable it automatically goes off.

1) Does it have a separate Ethernet Card, or is it integrated?
(Part of the motherboard)


The Dell Optiplex GX620 comes with Integrated networking.
The chipset is a Broadcom 572.
It's part of the motherboard, and you plug the Ethernet Cable into the back of the computer.

However, you could have a separate Ethernet Card, plugged into the white PCI expansion slot on the motherboard.

A) If you are using a separate Ethernet Card, replace it.

B) If you are using the Intergrated networking of the motherboard, (Plug Ethernet cable into back of computer), use an Ethernet Card instead.

White PCI slot.

You have a short circuit when you plug the Ethernet Cable into the motherboard. Don't use the motherboard networking, use an Ethernet Card.

2) Plugging an Ethernet Cable into a computer that is on, = No.
It is not a Plug N' Play item.

(Not stating this is what you are doing.
Just posting in case you are. Burns out the Ethernet chipset on the motherboard)

Dell optiplex GX620 desktop has an ethernet port on it, that is not an adapter, I cannot connect to the internet, I downloaded and installed a driver for a wireless ethernet adapter, but that has not...


1) You can download a wireless Ethernet adapter driver all day, but if you Do Not have a wireless adapter card installed in your computer, the drivers do you no good.

Or if you do not have a wireless USB adapter plugged into a USB port.

Example of a wireless adapter card,

Example of a wireless USB device,

Example of an Ethernet adapter card,

If you are just going to hardwire the computer, just buy an Ethernet adapter card, (PCI version), and install it in your computer, (On the motherboard), in any available white PCI slot.

IF it is the Mini Tower model.

The Desktop, Small Form Factor (SFF), and Ultra Small Form Factor (SFF) computers, are too small in width for a regular size Ethernet adapter card.

They need a Low-Profile Ethernet adapter card,

This is for a Dell Optiplex GX620 Mini-Tower computer,

Scroll the page down until you come to the bold blue heading - System Board Components
This is an illustration of a Top view of the Mini-Tower's motherboard.

16 and 17 point to two PCI slots.
This is where an Ethernet adapter card that is the PCI version, will plug into.

PCI slots are White in color.
An example of a basic PCI slot, ( 3 are shown),

If you do decide to go wireless;

1) Wireless networking operates at half of the speed of wired networking.

A computer that is wired directly to an Ethernet adapter card, is twice as fast on the internet, as a computer that is connected wireless.

2) Make sure your Router is capable of wireless.
Make sure the wireless router has a built-in Modem, or that you have a separate Modem.

[ For DSL.
Phone line connects to Filter. Filter has a place for a telephone cable, and an Ethernet cable.
Ethernet cable connects to Filter, and other end connects to Modem.
Ethernet cable goes from Modem to Wireless router that does not have a built-in Modem.

Phone line connects to Filter. Ethernet cable from Filter goes directly to wireless router, that has a built-in Modem.

Computer has to have a USB wireless device, or a wireless adapter card, installed.

For additional questions, or to clarify anything I have stated, please post in a Comment.

I need to connect a D-Link router to my cable modem so that I can use my laptop anywhere in my home

Cable-modem <-- Ethernet cable --> WAN (or "Internet") port on the router

LAN port on router <-- Ethernet cable --> network-port on your laptop

Then, access the "built-in" web-server on the router,
and run the "Wireless Networking Setup" wizard:
* to set an SSID ("network-name")
* an encryption-level (Hint: choose 'wpa')
* a password for your wireless network

Then, disconnect the Ethernet cable from your computer,
and then "wireless available wireless networks".
Select your newly-created network, and connect to it.

I have an hp comp that wont connect to my netgear internet access

Define/explain "wont connect".

Are you trying to use an Ethernet cable to connect the two devices? If so, try a different cable, to rule-out a "bad" cable.

Do you have any software like "Norton Internet Security" on the HP? It is notorious for "blocking" attempts to connect to "unknown" networks.

Does your desktop computer have a wireless networking adapter that you are trying to configure/use?

Will any other computer, either via Ethernet cable or wirelessly, connect to the NetGear router? If not, then maybe the NetGear is the problem.

Any error-messages when you try to "connect" ??
Exact wording?

Files & settings Wizard XP Pro

1) Are you referring to the IBM ThinkCentre S50?
(S may look like an 8)

Also need the Type. On the back of your ThinkCentre is this information.
Example: TYPE 8125-E1U

(The S/N after it stands for Serial Number. Do not give this number out, except to authorized personnel)

(I can give you the direct link to Lenovo Support for the Ethernet drivers, with this information.
IF, upon installing the Ethernet drivers does not cure the problem,
look to see if there is an open, {Available}, PCI slot for an Ethernet card.

With the 'Pizza Box' style of computer case there may not be, nor may there be room inside.
However they do make low profile Ethernet cards. {Ethernet Adapter Card)

Or you can find it here,

It will go in an available PCI slot, or PCI-Express x1 slot.

2) The Model Name, and Model Number is on the bottom of a laptop. Usually in a white Service Tag of some sort, but older models may just have it etched into the plastic.

Usually close to the Windows Product Key, (Holographic sticker)

3) Use a USB to USB Crossover Cable.

A USB to USB Crossover cable, isn't simply two USB A male connectors on the ends of a cable.
There is a bridge in the middle of the cable.

It crosses over the wires.
(Easy explanation. In essence it crosses over the wires. In actuality, it crosses over terminals in the USB connector end.

This shows the pinout of a USB cable connector,

The style used for your desktop, or laptop will be a USB A style.
There are four pins in the connector.

Pin 1 is 5 Volt DC
Pin 4 is a Ground, or Negative connection)

If you have a cable with the ends in the same direction, you will BURN out the USB ports.

The crossover cable reverses these connections. (Pins)

I await the exact Model Number of your IBM ThinkCentre, and the Type.

As soon as i went from a 'B' to a 'G' router, my internet has slowed dow , worse than dial-up

The Belkin Wireless G Router lets users share files and a broadband Internet connection among their computers-without using networking cables. It features 802.11g technology that makes accessing files and networked peripherals-such as hard drives, printers, CD-ROMs, and DVDs-easier than ever. 802.11g technology provides you with networking speeds nearly five times faster than the current Wi-Fi (802.11b) standard. An integrated, 4-port 10/100Base-T Ethernet switch also allows you to connect wired computers to the network. 802.11g technology is the easiest wireless network to implement. The Router uses the wireless 802.11g 2.4GHz standard to offer you 400 feet of wireless coverage. 802.11g technology is backward compatible with the 802.11b Wi-Fi networking standard, so it allows you to implement faster wireless technologies in combination with existing 802.11b Wi-Fi networks.

so if use "g" type router the speed cannot be slow there may be some other problem....that let the internet speed down....check that......

I was told I could find tutorials on networking my 2 computers here?

Check Look towards the middle you might find a match

Technically to connect two computers together all you need is a crossover cable. But if you are planning on connecting to computers onto a network its best to describe more. I would then need to know what kind of Service Provider you have? and whats ur network setup like and so forth.generally for that you would need a router to split an internet connection to two computers. the router would have to be connected to the service provider modem.

Read above links and they should help you out. If you need any more info. Please let me know.

it will as long as the modem/router is connected to a phone line, instead of the pc, the only cable connected to the pc should be a ethernet cable; or you have the pc networking set that it connects via another pc instead of through a gateway, re run the wireless network wizard.

Connect two computers together


Technically, yes. Both computers should have an Ethernet port (LAN), a crossover networking cable, peer to peer networking using static IP add, and Internet Connection Sharing on the PC with the Wireless Internet Connection. If by chance the PC with the Internet access is already using its Ethernet port, a second NIC could be installed.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
