Why is my Wifi speed much slower on my PC than my M1 MacBook Air

I have a custom-built Windows 10 PC with Tp-link ac1300 High Gain USB 3.0 Adaptor for Wifi, and the internet download speed is only 36.8 MB when I check it on the internet download speed on Google. But on my M1 MacBook Air, the download speed is 177MB. I checked to see on my Windows PC to see if anything in the background was downloading, but nothing was downloading. I updated the drivers and still nothing. Both computers are in the same range as the modem. I'm also downloading the files to the SAMSUNG 990 PRO SSD.

I even changed the Tp-Link Ac 1300 to a Gigabyte 11ac Intel Wireless PCIe WIFI and Bluetooth 4.2 Card- GC-WB867D, and it's the same issue: download speed is slow.

What's causing slow download speed on my Windows PC?

Edit: forgot to add my PC spec

Intel 6700K at 4.4ghz
ASUS MAXIMUS VIII GENE M-ATX Motherboard
16GB DDR4 Ram
ASUS Nvidia 3060 12gb
Samsung 990 Pro 1Tb SSD

Edit 2: I wiped off Windows 10 and reinstalled it. Same issue. I checked the download speed on my iPhone and Xbox One, and it's the same as my MacBook Air.

Try an Ubuntu live image and see what it’s like.

Does the pc have an extended antennae or is it down the back of the pc?

Is the upload speed similarly slow?

So I manage to figure and out why. I changed setting by going to Device Manager>Network Adaptor>TP link AC 1300> going to Value section and changing it from Auto to “IEEE to 802.11ac”. It worked like a charm. Downloaded GTA 5 on Steam at 140mbs
