Tp-link EAP225 V3 keeps rebooting

Installing and Using OpenWrt Network and Wireless Configuration
1

hi everyone and good day

i have a tp-link EAP225 v3 (EU) with OpenWrt 21.02.3 as AP, and it's doing well.

but ... when I set the TXpwoer of the 5GHz band above 19 dBm, the device keeps rebooting after connecting my phones and laptops.

i checked quicly the last line in the system logs befor rebooting:
Fri Jun 10 18:37:21 2022 kern.warn kernel: [ 2036.154251] ath10k_pci 0000:00:00.0: Invalid VHT mcs 15 peer stats

my setting for 5G
Channel: 44 Width : 40
Encryption: WPA2 PSK (CCMP)

my setting for 2G
Channel: 13 Width : 20
Encryption: WPA2 PSK (CCMP)
TXpower: 20

if anyone has an idea, I would be greatfull

1.) Discover the phone or laptop causing your issue.

Wait...

  • What country [setting] are you in/do you use?
  • Is that the setting on the AP?
3

country setting: TW (Tiwan)
yes >> this is my setting

notice, the problem caused by the 5G only. i try many settings in 2.4, it works perfectly.
but when I increase the txpower in 5G above 19 dBm, the problem comes here.

Some nations have a power restriction on channel 13 if it's allowed.

I cannot find information on TW. Perhaps you should test on channels: 1, 6 or 11 and see if it reboots.

Oh....are they the same SSID?

If you don't set a txpower, the radio should default to the highest power it is capable of, and that's usually what you want.

This is definitely a 5 GHz problem. It should be running the -ct-smallbuffers ath10k. Not using the smallbuffers version will definitely cause crashing on a 128 MB RAM. You can also try the non-ct ath10k.

yes .. the problem in 5GHz .....

i had test with the default country drive, but the problem is the same with this message:
Fri Jun 10 18:37:21 2022 kern.warn kernel: [ 2036.154251] ath10k_pci 0000:00:00.0: Invalid VHT mcs 15 peer stats

trying non-ct ath10 didn't solve the problem

Thank you mk24 for responding
