linksys wireless router security enable

I have a Linksys Etherfast Cable/DSL router BEFSR41 V3. How do I enable the the wireless network security?

I tried several suggestions already and can’t seem to find the menu to turn on the wireless security. I am accessing the Linkysys prog by entering 192.168.1.1. Somebody please help me!

under secuirty or wirless enable encryption, pick WPA-PKA and put in the key you want for the wireless signal, then in the network settings on your PC put in for encryption type WPA and put in the key..
