Seems too obvious but this is exactly what happens when the WEP key is not input correctly or the firewall prevents authentication. Re-boot the router. Enable WEP - get the passkey and write it down. Then make sure you input numbers as its easy on a BB to put in letters. Then check your firewall settings on our router. Is it set to enable connections? firewalls will prevent anything attaching itself to your router if told not to. Good luck. This isnt a problem with your BB, this is a router issue.
