cant connect to router belkin 54g

Hi i have a problem,

Totally my fault and feel a right tool for doing it but i have locked myself out of my device by inputting the wrong security setting in the wep mode by putting incorrect keys 1-4 and generating 4 keys and a new pass key, however it does not match my device and everytime i search for the modem its there but with a red cross on it and an error message saying i cannot connect to this modem due to wrong settings saved on this computer,

oops, The connect button is also faded and not available. How can i resolve this to get my pc synced up with the router once more?

Any advice will be appreciated.

Regards Daz
