Hello,

I have a very strange behaviour on my laptop Aspire A515-51G(NX.GVREP.014) with qualcomm atheros qca9377.
Problem exists on  802.11n 2.4Ghz(channel 11) and 802.11ac 5Ghz connection(channel 100).
While download any file it is downloading with max possible speed(30MB/s), but after a moment, seconds, sometimes minutes it drastically falls to lower than 1MB/s and it won't go back up even when i stop downloading, that makes work, game, video calls impossible.
I found only one solution that works: turn on or off bluetooth in windows 10 settings. It makes my download speed back to normal for a moment again but falls again anyway...


What i tried to fix it:
  1. Clean windows 10 factory reset
  2. Install every driver version for qca9377 and bluetooth i found, from the oldest(12.0.0.312) to the newest(12.0.0.916)
  3. Installing drivers listed by acer
  4. Disabling bluetooth from device manager
  5. Disabling every non microsoft services
  6. QOS/WMM is disabled on router
  7. Flushing dns, reset winsockets and ipconfigs
  8. Disabled autoturing
  9. Disabled fast boot from power management
  10. Setted wifi to max performance in power management
  11. Disabled power saver for qualcomm atheros qca9377 and bluetooth
  12. Tried to check if i can fix it with reseting any bluetooth service but not.
  13. On cable speed is correct but i can't use it because main pc is connected with LAN. 
  14. Disabled automatic proxy
There is something i can do to fix that downloading speed except buyng external wifi adapter or using cable?
In the worst scenario maybe there will be possibility to create as script to turn on/off bluetooth every 10-15 seconds but i would like not to use that solution forever...

    Nothing changed.

    It is already set at maximum performance. 

    Actually i'm able to keep my download speed pretty high for 5 minutes due to spamming bluetooth turn on off, i don't know why...
  • Have you checked if the problem remains when you connect the notebook to another network?
