Acer F15 Wfi Fi

Just bought an Acer F15  (F5-573G-58GV)

The set up process was fine including an update to win 10 Creators.

But....

The Wifi connection is running 50 % slower than my old Laptop and 50% slower than when connected with an Ethernet cable.

So far I have updated the Network Adapter (Qualcomm Atheros QCA9377 Network) Driver.

and in the Power Saving Settings, Wireless Adapter Settings have both Battery and Power Settings on "Maximum Performance"

Made no difference to the slow WiFi.

Any help woould be appreciated.

Edit: WiFi speed has just increased, so maybe windows was still updating "stuff" and has now finished.
