I can use my Wifi without any problems (used Router: FritzBox 7360 / WiFi n+b+g / connected via 2.4GHz, Ch.7, Bandwitdth 40 MHz, WPA2, Streams 1 x 1, Link Quality=69/70 Signal level=-41 dBm).
My notebook Acer Aspire E15/E5-575G-57WP has a built-in QCA9377 network adaptor using ath10k_pci driver:
Code: Select all
Network controller: Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)
Subsystem: Foxconn International, Inc. QCA9377 802.11ac Wireless Network Adapter
Kernel driver in use: ath10k_pci
Kernel modules: ath10k_pci
I noticed it because my radio stream instantely begin to stutter - it turns out that is have constantly to buffer its 128k-Stream - which is not normal!
I had a look in the WiFi-Monitor of the Router/FritzBox and found a nearly 100% Wifi-workload without making anything heavy via WiFi (see screenshot).
I tried to change WiFi-Channels - but without any luck.
I found various similar issues in other forums, often in connection with same Chipset QCA9377 - but not any solution I would be confident to try on my LinuxMint 20.1. Most suggested solution are years old and I am not sure if they are not anyway integrated in LM or the kernel (I am on 5.4.0-70-generic).
Could you give me a hint what could be worth to try, maybe of the following suggestions:
- blacklist device in btusb.ko (another Link) (it's from 2018 / Kernel 4.18.x / stated "this issue was solved in Linux 4.16"(so nothing for me???), and I never built anything myself...
- changing "Power Management:on"-->off (Link 1, Link 2. I don't know about any other consequences and are unsure if it could be the root cause
- patching firmware of Chipset: Link1 Link2 (don't know if it could be the same from ArchLinux to LM?) Link3
- Also about firmware a very promising Link 4 (it is for the same notebook, but for Lubuntu 16 / shows instructions to replace a "board-2.bin" file with a newer one, but I think I have already the newest file. Also not sure if firmware-5.bin and firmware-6.bin has anything todo? Or something similar with this git? (seems promising - and it is just copying and renameing, no build modules etc.?). But I cannot check if this is also valid for my system)
bt_coex_
- parameter only exists for iwlwifi. My used aht10k_pci only supportsirq_mode
andreset_mode
. So no solution of this Link1

viewtopic.php?t=297124 --> resulted in gaving up and buying a external BT dongle - thats nothing for me!

On Windows 10 on same machine is working fine. Connecting Android-Smartphones via Bluetooth to the Bose-box and using wifi also works fine.
So anything you would suggest me to try to solve this problem?
Thanks for any comments of my points above (especialle with the firmware part) - or you have any further ideas?
