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. There is something i can do to fix that downloading speed except buyng external wifi adapter or using cable? On cable speed is correct but i can't use it because main pc is connected with LAN.Tried to check if i can fix it with reseting any bluetooth service but not.Disabled power saver for qualcomm atheros qca9377 and bluetooth.Setted wifi to max performance in power management.Disabled fast boot from power management.Flushing dns, reset winsockets and ipconfigs In other words, you need to download/install driver for your Qualcomm Atheros wireless network adapter on your computer.Disabling bluetooth from device manager. Install every driver version for qca9377 and bluetooth i found, from the oldest(12.0.0.312) to the newest(12.0.0.916).It makes my download speed back to normal for a moment again but falls again anyway. I found only one solution that works: turn on or off bluetooth in windows 10 settings. 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. Problem exists on 802.11n 2.4Ghz(channel 11) and 802.11ac 5Ghz connection(channel 100). product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller. jarvisramanavenkat : sudo lshw -c network. My linux kernal version: jarvisramanavenkat : uname -r. I have a very strange behaviour on my laptop Aspire A515-51G(NX.GVREP.014) with qualcomm atheros qca9377. My laptop is dual boot consists of Windows & Ubuntu 20.04.
