    It is a desktop. When I go to view all connections, there is no wireless option at all. I am wondering if I need another wireless card, or can I attempt to re-establish the computer to the network?

  • 19lucy59 Feb 03, 2010

    OK. I will try that. How can I reach you later? I won't be able to attempt that for a few hours, but I would like to try to resolve this today if possible.



    Thanks!

    About 3pm today.



    Thanks!

    Sorry, I am on PST (west coast time!)



    What time to you leave for the day & how late will someone be available?



    Thanks!

    Hi. I am at home now. Question about the drivers...Is it possible to download them off of a working computer & transfer them to the computer that is having problems?

  • 19lucy59 Feb 03, 2010

    I do have a USB. I just need to know where to go on the working computer to get them.

  • 19lucy59 Feb 03, 2010

    It looks like two possibilities:



    1. 3Com 3C920B-EMB Integrated fast Ethernet Controller



    or



    2. NVIDIS nForce MCP networking controller





    The other 2 connections listed are 1394 Net Adapter & 1394 Net Adapter #2

  • 19lucy59 Feb 03, 2010

    Now don't laugh. I have no idea how to do that, where to find the card etc!

  • 19lucy59 Feb 03, 2010

    Wow! So many questions that reveal my ignorance. I know that all wireless equipment is in the garage. There is a black D-Link box with 2 blue Linksys boxes on top of that. There is nothing on either computer that has an antenna. I don't know how the computers in the house communicate with the equipment in the garage.



    The computer that is not working was built out of many components (by my husband) ordered from New Egg. It is not a propriatary computer like Dell or Compaq. I don't know how to tell you who the components are made by.



    Unfortunately, he is not around to ask.

  • 19lucy59 Feb 03, 2010

    Bingo! Looks like he used black anntena that plug into the back of each computer. I unplugged the one from the non-working computer. What next?

  • 19lucy59 Feb 03, 2010

    Well, I played "musical adapters". I took one from a working computer & placed it on the non-working one. Then I took the one from the non-working computer & placed it on a working one. Guess what? There was no difference on either computer. The working computer continued to have internet access while the non-working one continues with it's problems. I noticed another thing. The light next to the adapter port is not lit on the non-working computer. Could that mean anything?

  • 19lucy59 Feb 04, 2010

    OK. Now how do I access the drivers & put them on a USB for transport to the non-working computer?

  • 19lucy59 Feb 04, 2010

    Right......And I get in to the computer case how?

There is no problem with your wireless router. Need to check the wifi network adapter in your non working system. Whether it has properly configured or drivers has been installed. Check the status of the WIFI network adapter in device manager. Also check whether you have provided the secure password properly.

If the other computers are connecting OK through the wireless, then the problem is with the computer that won't connect. Is the problem computer a laptop or desktop computer?

    You can try re-installing the drivers for the wireless card. If you have the drivers, let me know (the original CD that came with it). If not, we first need to find the drivers on the internet for the card so that we can install it. We'll need to get some information from the hardware manager on the problem computer in order to find the proper drivers before we uninstall the card.

    Yes, as long we have something to transfer them like a USB drive.

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    OK, on the problem computer, I need you to right click on My Computer and choose Manage.

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    Once in there, click on Device Manager... look for Network Adapters and find the name of your wireless card.

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    OK. It is none of those, so your card is not being recognized by the computer. Before you give up on the card, try pulling it out and reinserting it and then restarting the computer. If it is not recognized, then the card will have to be replaced.

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    That's quite alright. What kind of computer is it and what model?

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    The card that is in question will have an antenna on the back or a wire connection going to a remote antenna (or are you using a USB type wireless card?)

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    That is OK. In order to for the computers to communicate with the router, they either have to connect through a wireless connection or a wired connection. The wired connection would look like an oversized phone cable (round with 8 tiny slots in the plastic connector). If they are are USB wireless adapters, they'll be small adapters plugged into a USB port on the back or front of the computer.

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    It sounds like this is a USB device, so when you plugged it back in, it should be ready to go.

  • Mark Tidwell
    Mark Tidwell Feb 03, 2010

    If that does not work, you can try taking one from another computer and plugging it in. If it then works, you need to replace the USB adapter.

  • Mark Tidwell
    Mark Tidwell Feb 04, 2010

    From what you just told me, it sounds like your USB ports have succumbed to the power surge. This is unusual, but it does happen. When you plug the adapter into the USB port, the computer should prompt you for the software if it can't find it. Since the computer is not doing that, it is not detecting the USB adapter when you plug it in. The only other thing you can try is to plug it into another USB port. However, it is unlikely this will fix the problem as all of the USB ports on a computer usually run off of the same hub. If this is the case, you'll need to purchase a USB adapter card for your computer and install it into one of the PCI slots inside your computer case.

  • Mark Tidwell
    Mark Tidwell Feb 04, 2010

    Remove the connections from the back of the computer (labeling or remembering where each one goes). The exterior case is usually secured by screws around the perimeter of the back edge. Remove these screws and then remove the exterior case. This will expose the internals of the computer. You'll want to remove the defective USB card (if it is not integrated into the mother board). Purchase a new card to place in one of the available PCI slots. Insert the card and secure it with a screw at the top (you will probably have to remove a blank in order to insert the card into an available slot). Be sure to insert the card fully into the slot. Replace the cover and reconnect all the cords and wires. Power up the PC and once logged in the new hardware wizard should start. Have the install disk handy (if it comes with one), otherwise Windows will install internal drivers for the card. You should then be able to plug the adapter into the new card and be ready to go. The drivers are probably still on the defective computer and once the computer recognizes the adapter, it will activate the appropriate drivers.

Dell inspiron 560 won't recognize network adapter


Try reinstalling the NIC driver. If its separate network card, connected in PCI adapter, try to remove and plug it back in to see if its found after.

If these actions do not help, maybe NIC was damager with the power outage, it can happen.

My computer won't connect to the wireless internet that every one in my house uses


When youclick Refresh network list, then Choose yourwireless network and then click Connect to your secured WirelessNetwork, it will asks for a Network Key before allowing you to connectinto your wireless network. This Network Key is either the WEP, orWPA or WPA2 Encryption key that is used to configure the Wireless Router. The Passphraseis an alternate way to setup the Encryption key.
When you are requested for a Network Key, you can just enter the Passphrasethat was used to configure the Encryption key in the wireless router.http://www.fixya.com/support/r5270415-network_password_network_addressFor information on securing your wireless network,configuring the wireless router and configuring the wireless card in thelaptop/computer, please click on this link and follow my instructions :-http://www.fixya.com/support/r3559128-wireless_router_security

To connect to your wireless router, it needs the router's wireless settings configured and also the wireless cards in all the laptops and or computers needs to be configured with the router's wireless settings. Then the laptops and desktop computers can communicate with your wireless router.

On my D-Link Dir-825 Wireless Router, can I change my wireless networks name without having to go around reconnecting all the computers in my house afterwards


If your network is "unsecure", which means no pass keys will be provided by client computer when they connect, then you can do it. Just change your SSID from your router's admin interface and your connecting computers will recognize it as a new network and try to negotiate connection. If there is a passkey, then the connecting computers will be prompted for a pass key (though it is an old pass key) since they recognize it as a new network.

IPod Touch does not connect to my home network?


In my case, I keep getting endlessly prompted to enter my passcode for my wireless router. I found that if I reboot the iTouch - hold down the top power button and slide the "slide to power off". Wait for it to finish powering off and then power it back on by holding the same button. When it comes back up it automatically connects to my home network again. Seems to happen every time I connect to an outside wifi network and then return home... I wish I knew WHY it does this - I suspect it has something to do with how my home wireless router is configured.

Make certain tha you have your firewall setting allowing the wireless card to connect. When you type your password in make certain that your caps lock is not turn on. Finally if your computer can only run wireless B, you have to tell your to broad wireless B and G, or do a protection mode, where older wireless device will connect.

Internet Connection Problem on One Computer


By any chance, are you trying to use something other than Windows to manage the wireless adapter? If you are, remove it.

Now, Click on Start, right click on Network highlight properties, and click on manage network connections on the Tasks menu.
Your two options will be the icons for your LAN and Wireless Network. Is it enabled and without red or yellow marks? It could be disable, it could be not connected and you can't view wireless networks because the switch is off, or it may just nut see your unsecure network (unlikely).

If the above is clear, right click on the wireless and highlight Properties and left click so it brings up the Networking tab. Highlight IPv4 and click on Properties. Make sure the Obtain dots are ticked. That should work, since you are running unsecured.
If it already is, check the red X or if it isn't click OK and close down the box.

Now, back to where your Wireless card is showing, right click it and you have Disable, Connect/Disconnect, Status, Diagnose etc.

If you're still Disconnected but not Disabled, click on Connect/Disconnect. Does it show your wireless network?

By this time, it should. If it doesn't post back. The other possibility is that you take your computer to a wireless internet cafe, McDonalds, Panera Bread, or motel with WiFi and test it there.

It connects to your wireless router just like your computer would, but not through your computer. On the phone just enable Local Wireless, this will temporarily disable the use of the phone function. Then a pop up will occur and say the phone recognizes your houses router if your in range and the rest from there is really simple
