Intel Dual Band Wireless-AC 3168 Terrible Performance

I recently bought a CyberPowerPC that came with a Gigabyte B450M DS3H WiFi motherboard. The on-board wifi is the Intel Dual Band Wireless-AC 3168.

 

My router is a Netgear R6250, dual band 2.4 and 5.0 GHz. I can connect to either 2.4 or 5.0 and have inexcusably slow speeds, 2.4 is even worse.

 

I have had nothing but troubles with this wifi. Every device on my network runs perfectly. My iMac is directly next to the tower with the 3168 and has no speed issues whatsoever on the same network. All devices on SpeedTest run about 200-240 mbps within about 1-2 seconds of the test starting. On the PC, if im lucky enough to even get to that speed around 200 mbps, it takes the length of the entire test before it even reaches that. It will slowly rise from 1-2-3-5-8-10-15 mbps etc.

 

This is especially frustrating because this PC is solely for gaming, which is no problem on my network for anything else. Even browsing the web is noticeably slow loading on this PC.

Hello BDye0,

 

Thank you for posting on the Intel® communities

 

Please run the following tool and attach the report generated. 

 

1. Intel® System Support Utility (Intel® SSU) 

  • Intel® SSU Download link 
  • Open the application and click on "Scan" to see the system and device information. By default, Intel® SSU will take you to the "Summary View". 
  • Click on the menu where it says "Summary" to change to "Detailed View". 
  • To save your scan, click on "Next", then "Save". 

 

Questions:

  • What is the expected speed?
  • Was it working better before?
  • What is the speed that you get when the system is wired connected?

 

Regards,

Actually I found the solution... and it's nothing what "Intel" guys tell here in this forum.

Simply, in network card config, make sure that mode fot 802.11n/ac is set to 802.11ac, BUT for 802.11a/b/g set to "5G 802.11a".
Yes, you will not use 2.4G so also not sure if wireless screen projection would be possible - if you're using it.

It simply solved all my issues and transfer speeds.. I had 40Mbps DL and 90Mbps UL, now I have 300-320 Mbps DL and same values for UL.
