Technical Support.
Adapter Installation Problems
If your computer cannot find the EZ Connect Wireless PC Card or
the network driver does not install correctly, check the following:
• Make sure the adapter is securely seated in the PCMCIA slot.
When you insert the wireless adapter into the notebook’s slot, a
beep should be heard if the adapter is properly inserted. Check
for any hardware problems, such as physical damage to the
card’s connector.
• Try the card in another PCMCIA slot. If this also fails, test your
computer with another SMC2632W V.2 Wireless PC Card that is
known to operate correctly.
• When operating under Windows NT, make sure a PCMCIA card and
socket services driver is installed in your computer. Also check for
resource conflicts using the Windows NT Diagnostics utility.
• Make sure your computer is using the latest BIOS.
• If there are other network adapters in the computer, they may
be causing conflict. Remove all other adapters from the
computer and test the wireless adapter separately.
• Check for a defective computer or PCMCIA connection by
trying the adapter in another computer that is known to
operate correctly.
• If it still does not work, take out the wireless adapter. Delete
CW10.sys from c:\windows\system. Then go to "Control Panel"
and delete the adapter from your network configuration menu.
Restart your PC and reinstall the card.
Network Connection Problems
