Can someone give an explanation of wireless adapters?

    I opened up the computer, its simple, I made it that way. the slot I think is a x16

    Something similar to that haha.

    The model number I am unable to give since the huge graphics card is covering it up. Sorry.

    While technically true, a USB 2.0 connection can support up to 480Mbps...which is far faster than any wireless card is going to go anyway. So, a USB 2.0 port will NOT be a bottleneck.


    Generally speaking you can achieve 300Mbps using a standard 802.11n USB NIC. Using PIC-e with 802.11n you can achieve 450Mbps. You need a router and NIC that is capable here. This assumes 5 bars connection strength with everything else optimized.

    802.11ac changes the rules with it's beam forming and channel bonding technology on the 5Ghz frequency.

    The most important thing to remember with 802.11n is that if you are running in mixed mode you can't achieve speeds faster than 54Mbps.

    Therefore you must update your legacy clients "G or below", in order to run in the 802.11n Only mode because the legacy clients can't connect when running in N only mode. Using N only mode with channel bonding is how you get the best possible wireless speeds.

    As for 480Mbps being faster than Any wireless card, really? Maybe not. Lets see someone get this through a USB 2.0.

    Sure, if you are on the new 802.11ac standard...you can exceed USB 2.0. Very few people are using this yet. I didn't think the original poster was discussing this very new format.

    The question you need to answer first is What Kind of Router do you have?


    the adapter won't matter if the router can't handle the data stream.
    to answer some of your other questions
    you have different 802.1 (wireless transmission modes) a, b, g, n, an now a/c


    a,b,g = 54mbps and less
    n = upto 450mbps
    a/c = upto 1300mbps

    2.4GHZ only has 11 channels it can broadcast on
    5GHZ has over 20 channels

    wireless N-routers can transmit on 2.5GHz but maximum speed is 300mbps
    you need to utilize a 5GHz bandwith to achieve higher speeds

    to my knowledge only one a/c adapter can come close to attaining 1300mbps (really more like 1200mbps), I think it was an ASUS internal card.


    personally I use,
    the Netgear R6300 a/c router (it can do 1300mbps) just no adapters can go that fast
    and
    the Netgear A6200 adapters, my connect speeds are 866mbps

    I agonized over what to get, but I have to say they are absolutely flawless, and Netgear has great support, they will be able to help you with most things. Call them, they will tell you what to get

    I have some tablets with internal adapters and they can connect upto 300mbps (standard for most laptops and tablets)


    I believe my info to be accurate hope it helps.

    You should know better than to make such broad statements here in the networking forum.

    You might have explained partially, but KarterJK answered most of my questions in a way I can understand. What are legacy clients, channel bonding, etc. No need to scrutinize yourself for it.

    Yes, fair enough. But I still think 99% of the time my statement is applicable.

    I have a D-Link 802.11ac wireless adapter that plugs into the USB 2.0 port on my laptop. The Wi-Fi connection status shows a speed of 866.5 Mbps. When I test the wireless connection by sending a large file I only get around 200Mbps. I would guess that the USB 2.0 port is a bottleneck.

    It looks like the connection speed is not related to your actual throughput?
