    What is the best wifi security to use? Something that doesn't put too much off a load on the router's cpu, since I wanna get low pings when I'm gaming.

    the best security for overall use should be WPA2-PSK. if you have a Radius Server then you can use WPA2 Enterprise. if your looking low pings then you should really go for a wired connection.

    Ditto what Toxic said, PLUS, most importantly AES encryption; i.e. WPA2-PSK or WPA2 Enterprize (no difference between the 2 i.t.o. speed/load on router), but with AES, not TKIP or TKIP/AES.

    from what I've heard tkip is currently still quite safe, although it is used as a transition from wep. aes is supposedly done on hardware. wpa & wpa2 are almost the same with regard to security.

    TKIP is safeish, just a tad below AES, but is significantly slower.

    I don't believe TKIP has yet been cracked, except for a brute-force attack with poor encryption keys. However, while AES is done in hardware and is therefore fast, TKIP is done in software and will therefore be slower. And since the OP asked for "something that doesn't put too much off a load on the router's cpu", I will concur with others that have recommended WPA/AES or WPA2/AES.

    So AES is faster, it'll give me less latency in games over TKIP? What's the difference in WPA1 and WPA2. I mean they can both do TKIP or AES. So which on should I use?

    Ok, well now I have a question. I have a WRT54G running tomato set up with WPA2-PSK with AES.

    One of my laptops as a WPC54G v1.2 card
    It's running the latest drivers on the Linksys site (though I just noticed that there are much more recent Broadcom drivers I could use).

    Anyhow, nothing in the specs indicates there's any support for WPA2, yet Windows XP says I'm connected as WPA2.

    How can that be explained?

    I recently found that both my periodic client disconnects and problems with interconnecting WDS links between different firmware both went away when I switched from WPA/WPA2 PSK to WPA-PSK with AES. Stability is boring but great so although I don't really understand why, I'm sticking with that combo.

    WPA and WPA2 are pretty close to one another. WPA2 however, is the newer authentication/encryption scheme, and is therefore slightly better than WPA. But not so as you'd notice, as the benefits of WPA2 over WPA are mostly "nice to have".

    Further, WPA or WPA2 is an authentication/encryption scheme, while AES or TKIP is encryption methodologies; i.e. WPAx is the container holding authentication and encryption (and some other stuff) together.

    The WPAx functionality, also is a function of a thing called the supplicant. The supplicant is a piece of software that the OS runs over the drivers and other hardware linked bits provided by the wireless adapter and its driver. Thus, WPA or WPA2, is provided by Windows, Linux, Mac, or whatever operating system you are running.

    Also, WPA/WPA2 + TKIP/AES is probably the safest and most compatible when dealing with a mix of new and old clients and routers. Also it works in WDS, as WPA2 currently is not compatible with WDS.
