Kernel Wireless Messages

Networking WiFi
1

Hi everyone,

since a few weeks I discover some wireless problems. Unfortunately
the Connections breaks randomly for a few seconds from client to ipfire hostapd.
Now I´ve got the idea to ask the logs, and there appears
nearly exactly the same time the connections breaks following information:

EEE 802.11: disconnected due to excessive missi ng ACKs
kernel: ath10k_pci 0000:05:00.0: failed to flush transmit queue (skip 0 ar-state 1):

I recognize some entrys like blue0p0: STA 10:xx:xx:xx:xx IEEE 802.1X: unauthorizing port

I using IPFire 2.29 (x86_64) - Core-Update 185 and the WirelessCard is an Qualcomm Atheros QCA986x/988x 802.11ac Wireless Network Adapter

The Hardware Mode for Wifi is set on 802.11gn in the UI, if I set it to 802.11ac the complete Wifi is not working.

Has anyone experience with this issues or ideas?
Thanks in advance and best regards

Have you set a valid 5Ghz channel which is needed for ac mode?

Hi Arne,

no I didn´t, to be honest where can I set a valid 5GHz Channel
Is it set in HT/VHT Caps? If yes, I´m lost :frowning:

There is a dropdown field for the channel.

Only channel 36 and higher can used for ac mode (5Ghz)
Which works and is available depends from you country setting. Also some wlan cards are region locked (but ATH10K should be Ok)

Hi Arne,

sorry for my late answer. I was interrupted.
That means the channel selection in the WLAN AP Configuration is for both (2,4 and 5 GHz) and if I want to use Mode 80211 ac (included the 5GHz) I have to set the channel to 36 or higher.
If I want to use only 2,4 GHz Mode 80211 gn I can set the channels lower than 36.
Is this correct?

But I’m not quite sure if my kernel error messages belongs to the settings?

Hi again,

I did some tests and ac-mode is working now.
But, as I feared the error-message:
kernel: ath10k_pci 0000:05:00.0: failed to flush transmit queue (skip 0 ar-state 1):
still appears and the randomly disconnecting from wifi isn’t solved.

Has someone further ideas?
Thanks and Best regards

core186 has a new kernel but i have not seen any related changes on the ath10k driver in the changelogs. (there was one fix but that should result in a complete crash of the kernel)

core186 is in testing tree and should released in the next days…

Hi Arne,
I’ve installed Core186 yesterday, unfortunately the errors still appears.
I’ll try to install ipFire from scratch and lets see what’s happens then.

Keep you informed
