Hello PPime
Thank you for posting on the Intel® communities.
Upon checking the official website of your computer I can not see drivers for Intel® Dual Band Wireless-AC 3168 only for
Intel Centrino Wireless Bluetooth 4.0 Adaptor and Realtek NIC Driver.

Hi Adrian,
Here are the answers to your questions:
Yea, this is the original wireless card. I haven't changed the card.
It was a higher speed yes.
I have a 400MB connection, so I think it should be much higher than 30MB.
The router is downstairs and my PC is upstairs, but I've tested my phone and other laptops upstairs, and they get much faster download speeds than my PC.
Netgear R6900P
Yea, on my old router. Didn't have this problem. I don't have that router any more and it was quite old.
I haven't tried that yet, as I don't have a cable and I can't move my PC downstairs or the router upstairs.
Here's the Intel AC 3168 I have. It should be able to provide a much faster connection.
Hello PPime,
Thank you for your input.
You might try the following steps:
You might try the following:
Access the advanced adapter settings in Windows® 10
You may also try a clean wireless driver installation:
Step 1: Get the latest driver 19.51.28.1.
Disconnect the computer from internet access while doing the installation to avoid Windows* automatic updates.
Step 2: Uninstall your Wi-Fi driver.
Windows* may have an inbox Wi-Fi driver for your wireless adapter. You can't uninstall an inbox driver (you won't see the "Delete the driver software for this device" option). Proceed to the next step if you start seeing the same version of the driver installed automatically after it’s uninstalled.
Step 3: Driver installation.
Locate the driver you downloaded back in Step 1. Run as administrator, and follow the wizard to completion.
Best regards,

Hi Adrian, I tried those things but the speed remains the same.
Hello PPime,
Thank you for your reply.
This might be related to the router configuration or the distance between the computer and router and it seems that the behavior started to happen after the router was changed for a new one even if other devices have faster download speed it could be due to different technologies and customizations performed on the hardware by the system manufacturer of the devices, Actual wireless throughput and/or range will vary depending on your specific operating system, hardware and software configurations
After changing the bands from the router, channels, advance settings on device manager, clean wireless driver installation, the same behavior happens we will recommend you to contact the ISP service, they might guide with specific settings that can help you to increase the wireless signal and performance.

Thanks. I tried TCP optimizer and that seems to have fixed the issue!
