Why can't I connect my Nintendo DS to Wi-Fi?

DS Lite wifi connection problems?

• I keep getting told that for connections on the DS lite (for Pokemon Pearl) cannot connect to connections with a locked padlock beside it. I've tried connecting to the links that i have the wep key for, but when i enter the correct code, it says 'these settings are invalid' any help with that please??? I recently had to change from using an unprotected wifi to one with a wep key, and since then i haven't been able to connect for awhile and it's driving me crazy. the nintendo wifi ds help site hasn't really helped at all- unless i've missed some sort of important thread. ~i've heard about resetting the router somehow, or messing with its settings. will this really work? please help!!
