Question about Computers & Internet

Can't connect to internet on desktop computer

I have a desktop PC that my husband had built for me. I connect to the internet through a router, there is one more computer & an Xbox that goes through the router. Everything was working fine, & then I couldn't connect to the internet. The systray says 'Local Area Connection 4 A network cable is unplugged'. I have tried turning the router & modem off & on, changing the ethernet cable (used the one that connects the other pc, so I know it works), connecting directly to the cable modem & bypassing the router, and (through Device Manager, which said the device was working properly) uninstalling the network adapter then restarting the computer. Nothing helped. Do I need a new network card? Could it be something else? Any advice you have would be very much appreciated! Thank You!

Most likey the issue is with the network adapter. As it does not work even with the modem and router the card seems to be faulty.

Hope this helps.

Desktop computers do not usually have a wireless card installed. They will have a built-in LAN card that uses a LAN cable.
If you want to connect your computer using a wireless connection then you will need to install a wireless card in your computer and configure it to communicate with your wireless router.
Otherwise you can connect to your wireless router using a LAN cable.
Your wireless router may have built-in LAN ports and you can connect your computer to the wireless router using a network cable.

My laptop works using my Belkin router, but my desktop will not connect to the internet


hello

your notebook has WiFi, which is radio frequency internet, it transmits and receives radio signals (frequencies) . Your desktop, most likely, does not support WiFi on its own , so you need to use RG45 cable , ethernet cable to be connected from your desktop to the router.
lan-cable-rg45-cat5e-cat6-utp-ftp-acr2101-.jpg



So in other words thsi is what happens with your notebook and the router.
  1. your notebook has built in wireless adapter which translates data into a radio signal and transmits it using an antenna.
  2. A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection, to your modem (supplied by your Internet Service Provider)
The process also works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer's wireless adapter.

The radios used for WiFi communication are very similar to the radios used for walkie-talkies, cell phones and other devices.


you need to connect your desktop to the router via RG45 ethernet cable.

Is your cable modem also a wireless router?

From my search on it, it is not a wireless router.

This means you need to attach a hub or a wireless router to your cable modem so that more than one computer can connect to the internet simultaneously.

Go out and buy a wireless router. Connect the wireless router to your cable modem.

Connect your desktop to the wireless router with an ethernet cable.

Then you should have internet on your desktop.

Let me know if this helps. Give me a good rating and vote for me please.

Modem <-- Ethernet cable --> WAN port on router

LAN port #1 on router <--- Ethernet cable --> network-port on desktop computer

LAN port #2 on router <-- Ethernet cable --> network-port on laptop computer

If the router has built-in "wireless" capability, then use the desktop computer's connection to the router to "configure" the wireless adapter, i.e., pick an SSID, and establish a password, and then your laptop computer can use the SSID/password to connect "wirelessly" to the router.

How to connect wireless router, Netgear WGR614, to my computer?


4 steps to set up your home wireless network
1.
Choose your wireless equipment
The first step is to make sure that you have the equipment you need. As you're looking for products in stores or on the Internet, you might notice that you can choose equipment that supports three different wireless networking technologies: 802.11a, 802.11b, and 802.11g. We recommend 802.11g, because it offers excellent performance and is compatible with almost everything.
Shopping list
• Broadband Internet connection
• Wireless router
• A computer with built-in wireless networking support or a wireless network adapter

A wireless router
The router converts the signals coming across your Internet connection into a wireless broadcast, sort of like a cordless phone base station. Be sure to get a wireless router, and not a wireless access point.
A wireless network adapter
Network adapters wirelessly connect your computer to your wireless router. If you have a newer computer you may already have wireless capabilities built in. If this is the case, then you will not need a wireless network adapter. If you need to purchase an adapter for a desktop computer, buy a USB wireless network adapter. If you have a laptop, buy a PC card-based network adapter. Make sure that you have one adapter for every computer on your network.
Note: To make setup easy, choose a network adapter made by the same vendor that made your wireless router. For example, if you find a good price on a Linksys router, choose a Linksys network adapter to go with it. To make shopping even easier, buy a bundle, such as those available from D-Link, Netgear, Linksys, Microsoft, and Buffalo. If you have a desktop computer, make sure that you have an available USB port to plug the wireless network adapter into. If you don't have any open USB ports, buy a hub to add additional ports.
2.
Connect your wireless router
Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further.
First, locate your cable modem or DSL modem and unplug it to turn it off.
Next, connect your wireless router to your modem. Your modem should stay connected directly to the Internet. Later, after you've hooked everything up, your computer will wirelessly connect to your router, and the router will send communications through your modem to the Internet.

assuming you have a wireless router, make sure you have purchased the correct one, as cable and dsl routers are different, as cable modems need to be connected to the router via a cable and dsl normally have a modem that can't be connected to a router, and you will require a modem/router.

You can only share a wireless connection when the line comes directly to the router and not through a pc, as the pc with the connection will have to always be on.

Pc connection problems


Sounds like you are setup to use Internet Connection Sharing. don't do this. Have each computer connect to the internet via the router. If the router is wireless connect all computers wirelessly to the router that are wireless capable and any computers that are not wireless capable, connect them to the router via a cat5 cable to the cat5 ports on the router. This will solve your problem. BPCS

Server not found} NetGear WGR614 Wireless Router doesn't connect me to the internet.


Dear Loud Nouises,

Your router must be connected properly to the cable modem. This must be to the wan port on the router.

Next, the router must be set-up accordingly to recognize the modem's internet connections. Please ask for the IP address.. and other relevant informations from your internet provider.

Set -up your computer using the internet connections wizard on each of your respective computer.

This should work fine if all connections were correctly configured.
