Im using a wireless router and trying to connect to my laptop but I when I try to connect it tells me it cant find the certificate or it just wont connect.

Hi,

Is this issue still outstanding? It is unusual for a wireless network to require a certificate. How are you trying to connect the laptop to the wireless network? Are you browsing a list of available wireless networks and then double-clicking your network in the list, which then gives you the error? If this is the case, could you please confirm the exact error message and what type of wireless router you have? Thanks

Funny thing is when I changed it to a WPA encrypted connection it worked but when I use a WEP encryption it gives me the unable to find certificate error and it never asked for the key.

WPA is a lot better than WEP so, if that works, then stick with WPA and you'll have no problem
