Kernel errors all over

Installing and Using OpenWrt

Hi,

I'm using TP-LINK Archer C7 v4 with OpenWRT for a long time. While trying to configure OpenVPN for it, I saw these kernel errors, which I'm not aware of. What are these and how to correct them?

kern.warn kernel: [   13.590289] ath10k_pci 0000:00:00.0: Direct firmware load for ath10k/fwcfg-pci-0000:00:00.0.txt failed with error -2

My current firmware version is OpenWrt 19.07.2 r10947-65030d81f3 / LuCI openwrt-19.07 branch git-21.128.50949-ec81a49 with ver. 4.14.171 Kernel.

Thanks...

Hard to say when you have found them by chance when config another packages if you don’t know exactly when they started.
What else have you configured out of the standard setup?

I got a similar fault just by connecting a wifi light to WAN Tx data and every time the LED light up a kernel error was written in the log.

I guess you don't have a log server and a year of logs to look in?

I would I this situation simply start from the beginning by installing the latest 19.07.7 firmware and start all over with your configs.
And check the logs after every modification to see if and/or when the error comes back.
