Question about 450mbs adapters

[Phil_Moore]

I have a wndr4000 router with a top speed of 450 on the 5gz band. I have an adapter wnda3100 with a top speed of 300 on the 5gz band. I would like to know if I got the adapter with the top speed of 450, (the wnda4100 I think it is), would I see an increase of my actual real life throughput to the internet increase 50% (or how much?) given the following:

From the location that the computer in question is positioned, it gets a fair signal: ~-60db or 4 out of 5 bars. I'm only interested in the internet, not servers on the LAN. I presently get around 10mbs down from the internet. The cable service is rated at 22mbs down, max.

Also, I was not able to find an explanation, and I did try, for what HW or SW makes these speeds possible. Some discussion spoke of the number of antennas, but it was not clear if this is the only factor. What is different about an adapter that communicates at 450mbs compared to one that only communicates at 300mbs?

Thanks for any info.

If your internet service is 22Mbps going from a 300Mbps adapter to a 450Mbps adapter would give you no difference. You said you are only getting 10Mbps from your rated 22Mbps on the cable service. Is it possible to test this speed connected directly to your cable modem and a PC via an ethernet connection? What speed CPU do you have? What type of USB port is your adapter plugged in to? It is possible it is only operating at USB 1.1 speeds or something.

To get 450Mbps you need both hardware and software support. The AP and wireless adapter have to both support 3x3 antennas as well as 3 spatial streams.

NO..

unless you have internet speed higher than 300Mbps .......


so keeping wnda3100 will be just fine unless you are looking for LAN to LAN sharing/transfer to have better performance then look in to wnda4100 for 450Mbps speed but also other wifi devices needs to be reflect to chainging to wnda4100.
