Acer Aspire E15, MU-MIMO WiFi, Win10 x64, QCA 9377 Wireless Adaptor
I ran a few speedtests with different connections, networks, and devices:
- Laptop 1, WiFi on home router: Upload test crashes almost immediately.
- Laptop 1, LAN on home router: Upload test shows good upload.
- Android, WiFi on home router: Upload test is fine.
- Laptop 1, WiFi on Android 4G Hotspot: Upload test is fine.
Ran these multiple times. I concluded that specifically this laptop had a problem when using WiFi to connect to this specific home network.
Checked my router's page: Laptop is connected to the 5GHz Frequency Band, 40MHz Channel Bandwidth. All other devices seem to use 2.4 GHz Frequency Band, 20MHz Channel Bandwidth.
I don't really know how to solve the issue, because I don't know much about network configuration. All I know is I need the upload.
Do you know what might be wrong? Any leading ideas are welcome. Thanks in advance!
EDIT: I tried setting each band (2.4GHz then 5GHz) as preferred one by the WiFi Adapter, and updating drivers: didn't work.
