What does Mbps mean on a router?

Like some say 54 Mbps Does that mean the max speed you can get in speed test if you get your isp that high thats the max it will go or something? I hope you understand what i am saying.Also is this a good router?

Says its wireless N type and i need an n type as my current modem/router only has b/g and i think 54 Mbps. So i am sure it is an improvement but by how much i get 12 mbps on wireless this current router will i get my full or atleast almost full? On my Lan i get 25-30 Mbps and up 21-24 So if i get this router will i get atleast 20 Mbps wireless speed?

Theoretical speeds in Megabits.
TP-Link has a 450Mbps wireless dual band router.
300Mbps wireless routers has been on the market for awhile.
Dual band is a good idea if your area is extremely wireless 2.4Ghz noisy.
5Ghz band can give you more channels.

You will certainly get a better connection speed using wireless N than wireless G, however any wireless connection you won’t get the full connection speed that you do by using an ethernet connection to your router, due to signal loss and interference (by whatever method, wireless/physical such as walls).
As Swords To Plowshares has posted above, dual band is useful if you live in a built up area and are getting interference on 2.4 MHz band. If you use something like inSSIDer 2.0, you will be able to see what is going on in your area.

If you are getting wireless N, I personally would go with the 300Mbps (I use at home) they usually broadcast across 4 channels at once (often referred to as neighbour unfriendly mode) but you will get much better reception and throughput, but bear in mind, you need compatible wireless adapters/cards in all your equipment to take advantage. Wireless N (300 Mbps) is great if you want to stream HD movies across a wireless network at home.
Also – don’t use sites like speedtest, they are thoroughly unreliable. Try downloading a large file from a fast server, such as an Ubuntu ISO to check your download speed, you don’t need to download the entire file, just wait until the speed settles, then you can stop it.

From What I heard, But I don’t know I talk alot of crap, As far as I understand 54 mbp/s is megabytes per second, I think…And You download in MegaBits persecond..I think, So, When your download speed is 54 megabytes per second Its rougly 5.5mb as your max download speed..Something like that Your answer is 5.5 ish Mb not 54mb Which is still Good.
Answer #5
not its not megabytes its megabits get your facts straight 54 mbps is about 6.5 megabytes per second which is not bad at all but ofc that depends on the speed
of your connection…
Answer #6
In all cases a dual band router is a good buy, future proofing and your guaranteed acceptable streaming speeds.
Some firmware might actually kill a router, its never for certain.
Answer #7
True that and one or more proper antennas (30-50db gain) instead of the tiny ones it comes with will boost your range
