I recently updated my ISP from 250Mbps to 1Gbps.
Mobile devices are now achieving 300+Mbps connections using speedtest.net
My Dell Inspiron 15 7000 Gaming laptop is only achieving 131.49Mbps, which is about the same as prior to the ISP and modem update.
I have updated to the latest intel drivers. I have enabled U-APSD support. There are no device priorities configured in the ISP modem.
Here is the netsh wlan show interface:
netsh wlan show interface
There is 1 interface on the system:

We understand you have recently upgraded your Internet service speed, and are able to accomplish better download speeds from all connected devices except for your laptop using the Intel® Dual Band Wireless-AC 3165.
It's important to note that this adapter is mainly intended for productivity, not high performance usage, as it uses a 1x1 antenna configuration (one antenna supporting one data stream). Other devices on your network may use the more common 2x2 antenna configuration, allowing for better download speeds (throughput).
Looking at the reports you've shared, it seems your adapter is not communicating with your router at it's theoretical maximum of 433 Mbps, but it's not terribly far from it.
Adapter: Intel® Dual Band Wireless-AC 3165 (1x1)
PROSet\Wireless Software: Version 20.40.0
Security: WPA2-Personal CCMP
Band: 5 GHz
Rx/Tx Rate: ~ 325 to 351 Mbps
The main difference between connection (receive/transmit) rates and download speed, is that download speed is a simple average measuring how fast a small file is downloaded from the test server. Download speed does not account for network overhead and environmental factors such as routing, encryption, RF interference, and user congestion. Your connection rate, on the other hand, measures the overall speed at which you're currently able to transmit data between your computer and your router.
Your maximum download speed can be roughly estimated at around half (~50 to 60%) of your connection rate. Depending on your wireless router, user congestion will have a greater or smaller impact on user experience.
Here we can make the following recommendations:
Please let us know if this helps.
I have the same problem with one of my laptops with the dual band ac-3165 adapter. getting only about 20mbps upload. Another laptop running simultaneously with a dual band ac-8265 adapter gets over 350mbps on the same network. What could cause this and how do i improve the performance of the ac-3165. Both laptops were purchased at the same time about 18 months ago.
