Internet connection problems


A bit vague problem description, but try this. I am assuming you are using wi-fi.

If you have a network icon in your system tray (looks like the bars on your phone), left click on the icon and see if wi-fi is turned on. If no, turn it on. If yes, select your network, click connect, enter any passcodes, and see if you are in business. If wi-fi is on and your network is not shown, your router is not broadcasting (not a PC problem).

If no icon, open your device manager (move cursor to the right of screen, wait for menu, select settings, select control panel, select device manager). Under the Network Adapters entry, look for your wireless device, right click, and select uninstall. Make sure the "remove software" box IS NOT CHECKED... Reboot your machine. Sometimes if a device gets hosed, removing it and rebooting to let Windows reinstall it fixes the issue. If you do not have a wi-fi entry under Network, then you either do not have a wi-fi device, or the one installed is not working.

Good luck.

Compaq presario v2000 wireless card not showing up in device manager


In Device Manager click the tiny arrow beside Network Adapters. This where the wireless card should be listed.
Next, locate the row of small icons just below the View tab at the top of Device Manager window.. Click the icon on the right "Scan for Hardware Changes".
Check again under Network Adapters to see if the wireless card is listed.
Or, check for any yellow exclamation marks in Device Manager list. An item might be named Unknown Device. Double-click it and select Update Driver.

I dont have a local area icon on my optiplex gx 520


check in the device manager for network adapters, it may need the drivers installing.
right click the my computer icon, select properties, click the hardware tab, then on device manager.
under the network adapters your card should be listed, if there is a yellow triangle you will need to reinstall the driver, check the dell website for the drivers.

hope this helps

Wireless network


Troubleshoot a Compaq Wireless Network Card

step 1

Open the Compaq's "Start" menu and type "Device Manager" in the "Search" box. Click the "Device Manager" icon.

step 2

Scroll down to the "Network Adapters" heading and click the plus sign to expand the list of attached network adapters. Right-click the name of your computer's wireless network card and choose "Uninstall." Follow the uninstall prompts on the screen.

step 3

Close the "Device Manager" window and return to the "Start" menu. Click "Restart" and wait for the operating system to boot up again. Follow the "Found New Hardware" prompt that loads on the screen to reinstall the network card.

step 4

Return to the "Device Manager" window and right-click the network card's entry again. Choose "Update Device Driver." Follow the prompts to install the latest driver.

step 5

Check the left side of your Compaq computer if you are using a laptop to see if it has a wireless network switch. Push the switch over to the "On" setting if it is set to "Off."

step 6

Open the "Start" menu and click "Network." Select the "Network and Sharing Center" icon at the top of the window.

step 7

Click the red "X" icon to have Windows automatically search for the problem. Follow the prompts to diagnose and resolve the network connection issue.

step 8

Double-click the networking icon in the system tray at the lower, right corner of the screen and click the name of the network you need to connect to if you are using Windows 7. In Windows Vista, instead click "Connect To" in the "Start" menu and click the name of the network.

About laptop ethernet...


First figure out whether your hardware is ok and driver is installed properly. In Windows XP, click Start , right-click My Computer , and select Properties .
  1. In Windows 98 and Me, right-click My Computer , and select Properties .
  2. In Windows XP, click the Hardware tab, and then the Device Manager button. In Windows 98 and Me, click the Device Manager tab.
  3. If the Network adapters category is present with a (+) sign , then skip to Step 6. If Network Adapters has a (-) sign , continue to Step 5. Disregard adapters that do not reference an Ethernet Adapter .
  4. If a network adapter is not listed inside, do one of the following items based on the condition of the networking hardware:
    • Networking hardware is not installed. Install a new network card (desktop computer) or a new network PCMCIA card (notebook computer) per the card manufacturers' suggestions. This does not apply to on-board networking hardware.
    • The network card is not seated fully into its socket. For Desktops, remove the side-case, reseat the network card, and replace side case. For notebook computers, remove and reseat the network PCMCIA card. This does not apply to on-board networking hardware.
    • If the computer is older, it may need to have jumpers on the network card set to an IRQ and address range that is not already being used by another device. Remove the side-case, set the jumpers on the card, and replace the side case. Replacing the older network card with a newer Plug and Play network card is probably a better option.
    • For desktop PCs with on-board networking hardware, reset the BIOS:
      1. Restart the PC.
      2. Press F1 repeatedly when the first screens appear.
      3. Press F5 and Enter to reset the BIOS to default settings.
      4. Press F10 and Enter to save the settings and exit BIOS setup .
      5. Restart the PC.
      6. Check Device Manager again for the presence of the Networks adapters category. If the network adapter name is still missing, the on-board network adapter may be damaged. The motherboard should be replaced, or a PCI network adapter should be installed.
  5. If the network adapter is listed, but has a yellow exclamation mark over its icon c00060708.jpg , do one of the following:
    • Software drivers and supportive files may be missing or corrupted. Remove the device from Device Manager and reinstall the software by restarting the computer. See Step 5: Reinstalling network adapter software drivers .
    • If the computer is older, it may need to have jumpers on the network card set to an IRQ and address range that is not already being used by another device. Remove the side-case, set the jumpers on the card, and replace the side case. Replacing the older network card with a newer Plug and Play card is probably a better option.
  6. If the network adapter listed has a green adapter icon c00060709.jpg , the networking adapter is probably functioning correctly. If the PC still cannot connect to the Internet, make sure to complete the following steps before continuing:
    • The cable or DSL hardware may have stopped responding. Reset the cable or DSL hardware using the manufacturer suggestions.
    • There still may be a connection problem. Recheck the cable connections and replace any cables that have been pinched or that you suspect are bad.
    • The Internet Service may be down at your provider. Most Service Providers have a telephone support number. Call the ISP support number. If an outage is occurring, an automated response about system wide service outages will probably play. In this case wait until the service comes back.
    If the network adapter icon is listed without problems, and the connections, service, and modem are working properly, then refresh the networking drivers.
Thanks
