    So whats the differences between 802.11a, 802.11b, and 802.11g? Are they all "wi-fi" but different speeds/range? I've heard you can use 802.11b in a 802.11g system? Any clarification would be great.

    you can use a computer with a "g" adapter with a "b" router/AP, but not a "B" adapter with a "G" AP.

    also "A" is operated at 5.4Ghz instead of 2.4Ghz like B/G are. It has less range and isn't as good at penetrating walls/etc.

    BS. 802.11g is backwards compatible with 802.11b. Doesn't matter which and card or AP is. If either is b, the other will step down to match. Just like 10/100 wired Ethernet cards and hubs or switches.
