text: how do i encrypt wireless network router in 128 bit? i have cable with wired router and i'm considering buying wireless router. i have networking experience with wired, are there simple instructions with setting up wireless network? whether you buy d-link, linksys, or any other wifi router, encryption setup should be really simple.  the key is, well, the key.  whether you use wep or wpa encryption, you will need a passphrase.  some router firmwares will generate a code for you, but you can create one yourself.  just be sure that you make a record of it someplace in a text file.  once you enter the passphrase in the router and reboot it, all the wireless adapters in your network will need to add that passphrase to the profile set up for your network.  most newer adapter utilities have a connection wizard that helps you enter it correctly.  once all your adapters are updated, you should be all set.  now only those users with the correct passphrase can connect to your router.  no bandwidth thieves for you!
