The internet connection of this new laptop running Windows 10 works perfectly well with an Ethernet cable (10Mbps down / 1Mbps up as expected), but with WiFi download is okay but upload is (practically) zero. I was wondering if the Qualcomm Atheros QCA9377 driver was to blame. I updated the driver from 12.0.0.116 to 12.0.0.117 but it didn't help. Other people seem to have had similar problems with the wireless network adapter so I'm hoping someone has some suggestions.
