Throughout my house we have had a "Secured" Wireless Internet Connection with DSL.

Our internet service provider temporarily disabled connections because I suppose they were working on a couple things.

Once my internet is back up and running, my connection because "Unsecure." I entered my WEP key and now it's "Security Enabled."

Is there such a difference between Security Enabled and Secured wireless connections?

No, there is no difference between the two. There are only different types of wireless security.

They work be applying a public algorithm to a dynamic public key and a static private key. Most of them can be cracked within an hour. Honestly... it really doesn't matter. If someone knows how to crack wireless networks.. they can. The only person you're going to stop is the next door neighbor who's not paying for internet anymore, because they can use yours.
