I reset my linksys and i'm connected to the internet now, but i want to set up a password for it, i think WPA2 im supposed to do. the cisco box model no is a WRT160N V3.

i tried doing the start>run type in cmd then put the gateway password into the address bar, and it tells me to put in a password and i put in admin then default and it'll log me on but when i click the Security tab it tells me to enter username and password again so i reenter admin - default and it no longer works.

help please, thank you.
