Summary0000163: Problems with (QC9377) ath10k partially disconnecting with firmware api6
DescriptionAfter an amount of time without establishing a new connection, the wireless network interface (Qualcomm Atheros QCA9377 802.11ac Wireless Network Adapter (rev 31)) refuses to connect to anything until the wifi is disabled and restarted. How it is restarted (gnome interface, restarting NetworkManager or rebooting) does not seem to matter in terms of whether or not function returns or how long the interval is between occurrences.

The wired interface is not affected when this happens.

Interestingly, the interface does not have to be idle, and existing connections are not terminated (Zoom meetings and SSH sessions), but new connections cannot be created (ping, DNS queries, new SSH sessions). I have continued a Zoom meeting long after my browser stopped being able to do DNS resolution without an issue.

No messages were found in any of the logs or with dmesg when this occurs, and the network requests for new connections eventually time out. The interface still shows that it is connected and the system acts as if the Internet is disconnected at the router, although existing connections are not affected.

Disabling power management, first for the QC9377 network interface, and then for the entire system did not produce any noticable difference. it happens at roughly the same frequency whether connected to power or not.

All available updates were applied.

The problem turned out to be the firmware file: /lib/firmware/ath10k/QCA9377/hw1.0/firmware-6.bin
If this is removed, then /lib/firmware/ath10k/QCA9377/hw1.0/firmware-5.bin is used and the system functions properly. To verify the fix, use the desg command below and look for "api 5"

System information: This is a Dell Inspiron 3783

Diagnosis: see line 5 below ("api 6")

Steps To ReproduceThe amount of time to the appearance of the problem is consistent. The appearance of the problem is consistent. The key feature is going a period of time without establishing a new connection. Allowing the system to sit idle will cause the problem as well.

The system may be idle, but this is not a condition of the problem. I have had it happen during a ZOOM meeting, I have had it happen during an SSH session. What is consistent is that the wireless network interface refuses to establish any new connections, even to local addresses.
Additional InformationI am unsure if this the proper place to report this (it is an upstream product, I can't find a section for wireless drivers or the ath10k driver).

It drove me crazy for a week and a half I just want anyone else having the problem to be able to find the solution somewhere.
