    Windows 10 Not Receiving 5GHz Wi-Fi

    I have recently upgraded to a 150 mbps Wi-Fi plan, and have noticed that my laptop barely scratches 50. Apparently, this is due to the fact that my laptop uses, and can only use, the 2.4 GHz, despite both the laptop and the Wi-Fi stick supporting 802.11a/n. I'm guessing this is a problem with the OS now, but correct me if I'm wrong.

    Someone correct me if I'm wrong but I though 5ghz is called Wi-Fi standard, 802.11ac

    Does the router broadcast a 5G wifi signal? I use a modem & router combined & the 2.4G & 5G SSID's are different (ie routername & routername_5G), make sure the wifi adapter is set up with the 5G SSID name.

    As this ExpertReviews article states, both 802.11n and 802.11ac support dual band (2.4 GHz and 5 GHz) networking. 802.11ac does it faster.

    Your card is only n type is your router only n type to get top speed you need a Ac type router that supports both 2&5 gig and can in theory do 3 gig speeds what is you upload speed if your net is only 30meg having a fast wifi won't help it's only of use in local network speed your limited to you net speed

    The router is broadcasting A/N/AC, and all I need is my card to pick up at least one of them. It is currently broadcasting 5G.

    are you sure you are not confusing mbps and mb/s ? 150mbps is about 18-19mb/s (so same as a 20mb down plan....),000&unit=B/s

    That is the theoretical maximum of the connection remember ...NOT what YOUR laptop can sustain or obtain, even if the Hardware is capable due to interference , walls, etc in the way.

    Is the Router Dualband ? perhaps it only does 2.4 or 5ghz not both at a time ?

    Just because the Linksys is capable of 450mbps on N (3x3) does not mean your Router Supports that speed on N , your Router maybe only 2x2 or only 1x1 even perhaps ? The 1x1 wireless card means it has 1 receive antenna and 1 transmit antenna and can do a theoretical max transmission rate of 72Mbps. A 2x2 has 2 antennas for both receive and transmit and can do a theoretical max of 150Mbps. A 3x3 card has 3 antennas for both receive and transmit with a theoretical max of 450Mbps.

    So the problem your having is maybe an antenna issue ? ie it only has 2 antennas total (1x1). so only 60mbps with inference/range etc.

    OR Doctor9Fan maybe right , if both SSID's are named the same it maybe hooking upto the 2.4 Band as the signal is stronger and you can't tell it is on 2.4 not 5g. (see the link EdTittel posted)

    150 Mbps is 802.1n, SINGLE Band.
    802.1n can go up to 300Mbps.
    802.1n is 2,4GHz ONLY.
    802.1 AC is Dual Band, so 2,4 Ghz and 5GHz.
    150Mbps=4MB/s max. transfer rate .

    In Picture you see a Home Networking speed 300Mbps in Windows 10 . So, it is not Windows

    802.11n is NOT 2.4 GHz only. It works on both 2.4 and 5 GHz bands, but the latter requires newer, more capable (and expensive) 802.11n hardware (routers, interfaces and so forth) than original 802.11n implementations. Here's a snippet from the 802.11 page at wikipedia to buttress my assertion (I also have a later generation Asus 802.11n router in my office right now that's running on both 2.4 and 5 GHz bands):

    @EdTitel - My understanding of that table is, if a Device supports 802.1 AC then it is also possible to use 802.1n mode on 5GHz band.
    If a device is pure 802.1n then it will work on 2,4GHz band ONLY. My router is a 300Mbps and is a 2,4GHz only device.
    Worldwide most of devices that are not AC are 2,4GHz only.
    It is pointless to put a Router working on 5GHz Band and expecting that 2,4GHz devices somehow will work like that.
    I feel that many people sometimes are hopping a "miracle" will happen.
