I'm going to get a wireless card for my laptop computer. If the router says it broadcasts on 2.412 ~ 2.462 GHz and the card says it's 2.4 GHz, are they compatible? Or are those 2 different numbers?

yes. The first set of numbers were just discrete. They are compatible. Also you have to make sure that the letters corrospond. B is the lowest N is the highest.
N picks up N, G and B
G picks up G, and B
And B picks Up B

2.4 is a frequency range in which all wireless networks are required to run. 2.412~2.462 means that the router is about to transmitted several different channels (usually 12) between those two frequencies in the 2.4 range. So the card can see the frequency of the router.
But a second piece of information is also needed. Routers can use one of four different languages (or protocols) to transmit: A, B, G, and N. The A is rare and you will probably not be able to find a card or router for sale today that uses it.
B is only able to talk to itself. G can talk to itself and B. N can talk to itself, G and B. So you can mix any of the three and they will talk. (For example if the card is B and the router is N, they will talk "B", or if the card is N and the router is G, they will talk "G"). However B is the slowest, G is the standard, and N is the fastest (but so new that you will not find much of anyone using it yet).

im not sure about this one, this is a match ive never tested, id say try it out, and if it fails, then simply return the card. it never hurts to try. besides, those are just strength of the signal, you have to look at the broadcast

2.4GHz is the universal operating frequency band for 802.11g devices.. what u see on ya card doesnt refer to just a single frequency but the frequency band.there is a difference.
i bet they are both compatible.

Just look for the IEEE standard. thats what they are there for-Interoberability with different manufacturers. regardless of the brand, they just have to follow the same standard. 802.11a or 802.11b or 802.11g or the new 802.11n. most are backwards compatible as well.

those have nothing to do with it. 802.1 is the normal card and see if the roughter will pick up that signal those numbers you said are just the strengh of the signal

those just indicate different channles on a 2.4GHz, pretty much all routers and cards work , most of them are backward comaptible.
b,g,n in that order.

2.4 is 2.4 ... they ARE compatible.
I admit that the increased precision is confusing, but "2.4" really covers a swath of frequencies, not just 2.400000.
