Hello, what firmware are you using (ath10k-ct, or QCA?) If using -ct firmware,
please try QCA firmware and let me know if that fixes the problem.
Thanks,

I tried both. Both have the same problem. I tried various versions
of the both(-ct and QCA) firmware as well. All have the same problem.

Probably it is a board-file and/or calibration data issue then.
The debugfs 'ath10k/tpc_stats' file may show very low values?

I am not sure if the values are right. Here is one of the 5Ghz radio stats:

hi Ben,
I also looked at the TPC on the stock firmware on the AP. There is a
difference.
Here is the snippet from stock firmware:
TPC Config for channel 5765 mode 10
**************************************************
CTL = 0x10 Reg. Domain = 20
Antenna Gain = 0 Reg. Max Antenna Gain = 12
Power Limit = 63 Reg. Max Power = 60
Num tx chains = 2 Num Supported Rates = 109
**************************************************
**************** CDD POWER TABLE ****************
**************************************************
Where as in openwrt it is:
*************************************
TPC config for channel 5765 mode 10
*************************************
CTL = 0x10 Reg. Domain = 58
Antenna Gain = 0 Reg. Max Antenna Gain = 0
Power Limit = 60 Reg. Max Power = 30
Num tx chains = 2 Num supported rates = 109
********************************
So looks like reg ,domain is different even though both are US.
(Although I didnt set anything on stock firmware. The countrycode from
iwpriv get_countrycode says its 841.)
Also, the antenna gain seems different between stock and openwrt firmware..
How to change the reg. domain like in stock firmware in openwrt
although I set to US in the uci.
root@OpenWrt:/sys# uci show | grep country
uhttpd.defaults.country='ZZ'
wireless.radio0.country='US'
wireless.radio1.country='US'
wireless.radio2.country='US'
root@OpenWrt:/sys#
Thanks

hi Ben:
Looks like ./sys/kernel/debug/ieee80211/phy2/ath10k/cal_data is junk
for both the 5Ghz radios even though the
pre-cal-pci-0000:01:00.0.bin/pre-cal-ahb-a800000.wifi.bin is correct.
The 2Ghz cal_data seem to be correct and match the pre-cal-ahb-a000000.wifi.bin.
Openwrt seem to do the right thing in setting the countrycode.
I am clueless. Any pointers would help.
Thanks
