B . The security settings are too high could block certain actions, but scripting being disabled is a more common cause.

C . Pop-up blockers could prevent new windows from opening, but typically wouldn't affect document viewing.

A . WEP is enabled is related to security and is unlikely to cause connectivity issues.

C . There are speed limitations would cause slow performance, not intermittent connectivity.
