Make sure both the wireless router and your client are using the same Wi-Fi standard and configuration. If the router/client are using different wireless standards, Wi-Fi speeds will be limited by the lower of the two standards. Please check the Default/Recommended Settings for 802.11ac Connectivity If using the 5 GHz band, use channels 36, 40, 44, or 48. If using 2.4 GHz band, use only channels 1, 6, or 11. Connect only your Z370 Pro4-CB (Intel® Dual Band Wireless-AC 3168) computer to the wireless network and run the test again. Please post the results. Change the power options to Maximum performance. Go to Windows* updates, scan and apply all of them.
Was this working correctly as some point, but then begin to not work properly? And if so, what changed?
You don't mention the type of laptop this is. And it would also be helpful to know what type of wireless device you are attempting to connect to?
