Wireless Speed is slow and limited in windows 10

Hello!


I know this topic is asked many times, but I still didn't find any solution for my issue.

The problem is my wireless speed is not normal, it is limited/capped to ~4Mbps (~500KB/s), it should be ~60Mbps to connect to the internet.

I found some points regarding this issue.

  • My wireless speed is normal in Ubuntu, with the same device. It means that the problem is not my hardware, the problem is in Windows driver or software.
  • My wireless transfer speed is limited to ~4Mbps when I copy a file from a local network location (my PC).
  • I tried to install and re-install network drivers.
  • I even fresh install windows into a new disk (I just bought a new disk to replace this laptop's old one), and the problem occurs before I install lot of programs.
  • The speed still limited using 802.11bg connection (Its different, limited at ~16Mbps).
  • I tried many 'common ways' starting from flushing dns, reinstall drivers, and etc.
  • My wireless network interface is Qualcomm Atheros AR956x.
  • LAN connection using cable does not have any problem.

Any help would be appreciated, thank you very much.
