I'm running a Dell laptop with XP Pro SP3. I have a d-link airplus g DWL-G630 cardbus adapter. I cannot connect to wi-fi at some locations. I have no issues at some places where you set up an account but at others that are secure and you need to enter a passkey or password, when I try to connect it says it cannot find a certificate. I can connect to free wi-fi sites with no problems.
I also cannot connect to the wireless network at my friends house either yet another friend with an HP laptop with no need for an adapter card had no problems connecting. We changed the properties for the network on my laptop to match the settings on the HP laptop and it still says it cannot find a certificate. Is there a setting we are missing? We have also tried unchecking 'enable IEEE 802.1x authentication and updating the cardbus driver. Do I need to upgrade my cardbus adapter?
