Intel Wireless AC3168

HP Recommended
HP Slimline Desktop PC 270-p0xx
Microsoft Windows 10 (64-bit)

My wireless connection is very slow. I need to know if I can re-configure connection, card, etc.  Other devices in home are in excess of 150mb.  This computer is hetting 3.8mb upload speed!

Hi! @OMack,


Is the ethernet connection functioning correctly?


How far is the router from the PC?


Please share the product number of the PC to assist you better.


You can update the windows to the latest version and try updating the wireless drivers and BIOS on the PC to the latest version using the HP support assistant.

Note: Before uninstalling the wireless drivers make sure the PC is connected with an ethernet connection.
