I have a linksys router and, as my neighborhood has caught up with ages, I feel a need to secure my network. There are several options to secure it like WPA (several versions), and WEP. Which should I use?? Then, when I tried WEP, it asked for a pass phrase to generate these different numbers and letters. When my computer asks for a password, do I give it that complicated pile of letters and numbers, or do I give it the pass phrase? Thanks.
