RUTX11 Kernel log full with Invalid VHT mcs 15 peer stats

[starhopper]

Hello,
I got an RUTX11 with Wireless using STA as WAN Interface and AP for remote clients. I receive many kernel warnings like this:
Tue Nov 28 21:27:08 2023 kern.warn kernel: [81251.262086] ath10k_ahb a000000.wifi: Invalid VHT mcs 15 peer stats

Hello,

Thanks for reaching us.

Based on the logs, VHT MCS 15 refers to the highest modulation and coding scheme supported in the Very High Throughput (VHT) standard, which is part of the 802.11ac Wi-Fi standard, so its a sign that there is issue when trying to gather the coding scheme.

So, kindly note the following points to troubleshoot the issue.
1- • Kindly make sure that the firmware is upgraded to the latest one “7.05.4”, you can find the firmware file on link below

• RUTX11 Firmware Downloads - Teltonika Networks Wiki
• You can upgrade the firmware on the router following below:
  WebUI > System > Firmware > Update firmware > Turn off keep settings option > Upload the firmware

2- If possible, check the devices connected to your wireless network. Ensure that they are operating correctly and have updated wireless drivers.

3- Sometimes the channel that the router in is having a high data traffic, so kindly consider changing the wireless channel on your router, You can know the low data traffic channel by downloading a Wi-Fi Analyzer app on the phone

Thanks
