300Mbps wireless with 10/100 wired?

[Lpenguin]

I got a Netgear 834M wireless-N router and WN311T wireless-N PCI card for about $100 for both when CompUSA was closing up. As I am installing them tonight or maybe tomorrow as it is getting late now, I got thinking....

Together they are supposed to do up to to 300Mbps. But the router ports are 10/100. So how could you ever transmit data at 300Mbps? I will find out when I get it all going how fast they are, and I will by satisfied with 100.

Am I not understanding something here? The wireless may have the capability to transmit at 300, but the wired ports that feed the wireless are only 100. So what is the benefit of wireless-N without a gigaswitch in the router? Any enlightenment will be much appreciated.



******6-3-07 Set up the router and adaptor and according to the monitor program that comes with the adapter, I do transfer files at 300Mbps!!!!! And that is in another room across a hallway.

A 67 meg I moved with my old Airlink MIMO router/adapter took 25 seconds, with the netgear N 14 seconds, a 101 meg file in 21 seconds. It takes a few seconds to get up to speed, but it is clearly much faster. Should help the lag we used to get on lan games, which is why I upgraded.

Could it be that the router/adapter are connected at 300 and are actually transferring at 100? If that is the case, why build a N router without a gigaswitch. I would think that the monitor would show the actual transfer speed and not the connection speed to be useful.

Maybe the 10/100 numbers not be the same measurement as the wireless transfer numbers? I do not know how it works, but it does!


Posted this in the networking forum and did not get much response, I would sure like to know the explanation for the above if anyone knows.

Thanks

if it helps

101/21*8=38.5mbits

whatever it's supposed to be, that's pretty good for consumer 802.xx wireless

10/100 (Mbps) is the speed of the Ethernet ports on the router. Data that has to flow through these ports (such as traffic to the Internet) will be constrained by this. Though unless you have a really spectacular ISP (FiOS can exceed 10 Mbps, not much else can), it won't matter because the ISP will be the limiting factor anyway.

Data only traveling within the wireless network (from one wireless node, through the router, to another wireless node) will only be traveling through the 270 Mbps wireless links. It still won't actually hit 270 Mbps, but that's true of any 802.x standard; there's a variety of overhead involved.

The benefit is intranetwork stuff (LAN parties, PC to PC file transfers across the network, and the like where you're not transmitting to or from the internet)

And this isn't actually HT, it should've gone in networking

300 MB/s is for wireless to wireless connections. Wired to wirelless will hit 100MB/s. Unless you transfer a lot of files across the network, the wireless speed should not really matter too much.

Payload speed on wireless is half the advertized carrier bandwidth, less if more than one station is present, and if the stations aren't right next to the AP anyway. Wired ethernet in turn comes /very/ close to its theoretical figures in actual throughput.

So, in real life figures, a 100 Mbit wire link is plenty enough for a "300 Mbit" wireless AP.

lately i have been getting over 12Mb/s from cox, sometimes 14Mb/s but only late at night - 2-4AM, fwiw

i think you mean 300Mb/s and 100Mb/s....

Yes, three-hundred megabits per second and one-hundred megabits per second
