hey,
i got this router today and im a bit worried about some kernel messages:

should i be worried? because wlan seems to work... haven't tested the speed so far.

The forum search finds quite a lot of similar questions.
Does any of the findings help you?

thanks, that helped me.

another messages i get often:

Wed Dec  5 20:49:06 2018 kern.warn kernel: [29226.781214] ath10k_ahb a000000.wifi: rate-override:  Skipping un-supported device-id, hw-nss: 2 dev-id: 0x0

i can't even find this on google.

No, don't worry about these messages. The ath10k-ct driver is trying to load it own "preferred" -ct firmwares first. However the driver uses the recommended request_firmware_*() method and is very verbose.

This could be caused by a special device on your network and your network configuration.

From what I can tell, it's because of this check:

At first glance, it looks like there is no entry for the IPQ4019/QCA4019 device in the list. But there is a the twist: The QCA4019 dev-id is "0" (which is shared with WCN3990), so this is getting confusing.

@greearb ? If he doesn't answer, then please feel free to open up a issue report on his ath10k-ct project github page: https://github.com/greearb/ath10k-ct/ . Thanks.

thx.

i switched today to the non -ct firmware from https://github.com/kvalo/ath10k-firmware/tree/master/QCA4019/hw1.0/3.6, because the -ct firmware crashed two times in two days. i already reported this issue on github.

i also will report this, if greearb doesn't read this here.

Hello,

Ignore the rate-override warning, you don't need to override rates for any normal use case anyway. I'll comment out that warning from my driver in upcoming releases.

Please do report the crashes on the ath10k-ct project page so I can track them. I should be releasing new firmware images for openwrt soon and hopefully that will resolve some of it at least.
