Repairing disabled wireless card

Hi,
Previously my desktop computer was hardwired into an ethernet connection. When setting up my internet the Comcast tech mentioned he disabled my wireless card for better performance since the computer is now hardwired. I have since moved and am looking to again use my wireless card, how do I repair the disabled wireless card?

  1. what OS are you running?
  2. Window’s EP Professional
  3. go to START > SETTINGS> CONTROL PANEL

    choose NETWORK CONNECTIONS

    right click on the Wireless Network Card and click Enable
  4. thank you. unfortunately when i get into the network connections the only available network is a "LAN or High-Speed Internet"
  5. go to your Device Manager and check if it has been disabled in there

    go to START > SETTINGS> CONTROL PANEL

    choose SYSTEM

    under the Hardware tab click the Device Manager button

    see if there is a red X under the Network Adapters
  6. The only item listed under Network Adapters is the "Realtek ... Ethernet NIC" card.

    It is not "x"ed out.
  7. what type of computer do you have? When you look at the back of the computer can you see the wireless card (antenna)?
  8. The computer is an acer, aprox. a 2004 variety (old)

    & yes there is an antenna, I purchased and installed the wireless card independent of the original tower. I believe the card is d-link.
  9. Is there anything listed under Other Devices?
  10. Other Devices lists:

    Ethernet Controller
    Video Controller (VGA Compatible)

    Both the category & the subcategory have yellow question marks as icons, and a yellow circle w/ an exclamation point layered over the question mark for both sub categories.

    I am also going to find the install CD and see if I can get anything to show by reinstalling.
  11. right click on the Ethernet Controller and choose Upgrade drivers while you are connected to the internet
