Hi.
I've got some observation about firmware version and speed that I
would like to share.
I have tp-link archer c5 with 'ath10k_pci 0000:01:00.0: qca988x
hw2.0 target 0x4100016c chip_id 0x043202ff sub 0000:0000' running
Openwrt.
When I use firmware version 10.2.4.70.63-2 I get modulation speeds
about twice as large as with other firmware versions. I've also tried
10.2.4.70.66 and firmware-5.bin_10.2.4-1.0-00033 and one that was
Openwrt/Lede stock before that - all show performance noticeably worse
than 10.2.4.70.63-2.
In fact if my laptop stands on my desk (some distance away from AP)
and I use 10.2.4.70.63-2 I get stable 2 spacial stream reception, if I
use other versions mentioned above I usually get one 1 special stream
as shown by 'iw' command on a client.
I'm not sure if that observation if helpful or not, but since it
looks like newer FW versions have worse performance I thought I should
share it.
Please let me know if I can provide any more information.

Hi,
I also have same observations. Rx rate is not getting updated in iw station dump command
with firmware version 10.2.4.70.66.Data Throughput is also degraded by 30Mbps with this
version.My measure throughput was 180Mbps with firmware-5.bin_25_2.1 for HT40 mode(2x2).
Sometimes I can see 1 SS in station dump while my radio is 2x2.Is there any speed
difference for the FW version 10.2.4.70.66?
Please see my AP configuration below:

Hi,
WLE600VX (2x2 MIMO, QCA9888x chipset) is used as WiFi module in my access point. I am
working on certification project of this system, there I need to fix single rate in all
the legacy, HT and VHT modes for 20MHz and 40MHz channels.
There are two problems observed during this test:
1. 9Mbps legacy rate is always set to 24Mbps in g mode. While in a mode it is set as
9Mbps.What can be the issue, firmware or driver? any suggestions to see this issue?
2. Not able to set Short GI for 40MHz channels for all the MCS except MCS 7 and 15. What
cab be the reason for this. again, where should I suspect?..firmware or driver? Please
help on this.
ath10k version : git 16 oct 2017(v4.14-rc2-1-24-gc6db471)
firmware version : firmware-5.bin_10.2.4.70.66
Kernel version : 3.12
Thanks & Regards,
Kavita
