    1. Which encryption method is best to use?
    2. What is the performance loss (of any of the methods) if any?
    3. Which is easiest to set up
    4. Is one encryption better than another, if you are using the router as a AP only.
    5. Does any of the methods offer the ability to setup a username and password for people trying to connect.

    WRT54G v4.20.6
    WEP 64bit

    1. Depends on what your NIC will support, but WPA-PSK/TKIP gives good security if you use a strong (non dictionary) passphrase. You can generate and distribute it regularly via the link or an external device.
    2. WPA is only a slight performance hit, not generally noticeable compared to other factors.
    3. WPA is easy to use; just set up the WAP with the passphrase, then enter the passphrase twice on each machine for access. Only complication is passphrase distribution, but that is a common encryption problem.
    4. The AP is just the wireless portion of the router, so no difference.
    5. No; Just need the passphrase. You can also restrict to certain MACs along with the passphrase, but not a real addition to security because of the ability to clone MAC addresses readily. If you are worried about IDing users, the MAC address should do it for those who are trusted (have the passphrase).
